In today’s most advanced semiconductor, electronics, and laser processing equipment, motion control is no longer just about achieving position—it is about achieving precision, synchronization, and throughput simultaneously. As machine architectures evolve toward larger formats, tighter tolerances, and higher speeds, traditional control approaches struggle to keep pace.

This is where Smarter Gantry Control powered by MIMO (Multi-Input Multi-Output) algorithms plays a decisive role.

The Challenge: Coordinating Coupled Axes in Gantry Systems

Gantry stages are foundational to many high-performance systems—from wafer inspection tools to advanced packaging platforms. These systems typically utilize multiple motors driving a single mechanical structure, such as an X-axis beam carried by dual drives.

While this architecture enables higher force and longer travel, it introduces complex dynamic challenges:

• Mechanical coupling between axes (cross-axis interaction)
• Structural flex and yaw errors
• Varying loads across the beam
• Disturbances generated by one axis affecting another

In conventional control approaches, each axis is treated independently (SISO control). However, in a gantry system, axes are inherently interdependent, and ignoring this coupling leads to:

• Reduced accuracy
• Lower bandwidth
• Increased settling times
• Limited throughput

Moving Beyond SISO: The Power of MIMO Control

MIMO control fundamentally changes how motion systems are managed. Instead of treating each axis in isolation, MIMO considers the entire system as a coupled dynamic entity, where multiple inputs (drive commands) influence multiple outputs (axis positions and errors).

ACS’s Smarter Gantry Control leverages advanced MIMO algorithms to:

• Actively compensate for cross-axis interactions
• Coordinate multiple motors as a single synchronized system
• Maintain performance consistency across the stage travel

This approach enables higher bandwidth, improved stability, and more predictable system behavior, even in complex mechanical configurations.

Smarter Gantry Control: Key Innovations

ACS’s implementation of Smarter Gantry Control introduces several critical capabilities designed for high-end precision systems:

1. Dynamic Cross-Axis Compensation

Instead of reacting to errors after they occur, the system dynamically compensates for the impact of the moving cross-axis load changing the overall systems behavior.

• Minimizes cross-coupling errors
• Reduces beam skew (yaw)
• Improves contour accuracy

This directly translates into better throughput and positioning performance.

2. Dynamic Error Compensation

Advanced algorithms continuously correct system-level errors that arise from:

• Structural compliance
• Thermal variation
• Load changes

These corrections ensure consistent nanometer-level accuracy, even under varying operating conditions.

3. Position-Independent Performance

Traditional gantry tuning often depends heavily on position. Performance degrades at the extremes of travel or under different load conditions.

MIMO-based control eliminates this limitation by delivering:

• Uniform performance across the entire working envelope
• Consistent accuracy independent of axis position

This is especially critical in applications like wafer inspection and hybrid bonding, where uniformity is essential.

4. Simplified Tuning and Optimization

Despite the complexity of multi-axis dynamics, Smarter Gantry Control simplifies implementation:

• Integrated tools like FRF Analyzer enable efficient tuning
• Advanced algorithms reduce manual tuning effort
• Robust performance across a wide range of stage designs

This allows engineers to achieve high performance faster, reducing time to market.

Real-World Impact: From Nanometers to Throughput

In advanced packaging and inspection systems, Smarter Gantry Control directly enables:

• Sub-nanometer positioning accuracy for bonding and metrology applications
• Faster move-and-settle times, increasing machine throughput
• Reduced vibration and improved process stability
• Higher yield through improved positioning precision

For example, bonding applications require extremely tight alignment tolerances. By combining MIMO control with advanced servo algorithms, systems achieve both speed and precision without compromise.

Why It Matters for Next-Generation Machines

As industries push toward:

• Smaller feature sizes
• Higher process speeds
• More complex multi-axis machine architectures

The limitations of traditional control approaches become increasingly evident.

Smarter Gantry Control addresses these challenges by enabling:

• Scalable performance for complex machines
• Robust handling of coupled mechanical systems
• Integration with advanced algorithms such as learning-based control and force control

This positions OEMs to build machines that are not only faster and more precise, but also more adaptable to future requirements.

Conclusion: Intelligent Control for Intelligent Machines

The transition from conventional SISO control to advanced MIMO-based Smarter Gantry Control represents a fundamental step forward in motion system design.

By treating the gantry as an integrated, dynamic system rather than a collection of independent axes, engineers can unlock:

• Higher accuracy
• Greater throughput
• Improved system robustness

In the era of advanced packaging, precision inspection, and high-speed manufacturing, this shift is not just beneficial—it is essential.

The post Smarter Gantry and MIMO Control: Unlocking the Next Level of Precision Motion appeared first on ACS Motion Control.

As sequencing technologies push toward higher throughput, smaller reagent volumes, and more complex imaging and detection techniques, motion control requirements have escalated dramatically. Today’s genome sequencing machines behave more like advanced semiconductor inspection platforms than traditional lab equipment—and they demand equally sophisticated motion systems.

Why Motion Control Matters in Genomics

Modern platforms—whether based on optical fluorescence, nanopore sensing, single‑molecule real‑time (SMRT) detection, or emerging enzymatic approaches—require:

• Nanometer-scale positioning over range of travel
• Real‑time synchronization between motion and imaging
• Ultra‑smooth velocity and force profiles
• High‑speed step‑and‑scan movement to maximize throughput
• Multi‑axis coordination across stacked or hybrid (coarse + fine) stages

This blend of precision, speed, and stability is exactly where advanced motion controllers separate high‑performance sequencers from their competitors.

The Core Motion Challenges Inside Sequencing Systems

1. Ultra‑High Positional Accuracy Across Large Work Areas

Flow cells, wafers, slides, and consumables used in sequencing often span large surfaces, but detection still relies on sub‑micron or nanometer‑level alignment.
This requires:

• High‑resolution linear encoders
• Multi‑degree‑of‑freedom stage architectures
• Advanced error mapping and compensation
• Thermal‑drift mitigation for long‑run stability

These are the same types of challenges seen in metrology and semiconductor inspection, making high‑end motion platforms a natural fit.

2. Deterministic Motion-to-Process Synchronization

Optical sequencing systems depend on tightly coordinated timing between:

• Stage motion
• Illumination
• Camera exposure
• Fluidic actuation

Technologies like Position Event Generation (PEG) enable sequencers to trigger imaging or sensing based on exact encoder positions—ensuring consistent data quality, pixel‑to‑pixel alignment, and reliable chemistry cycles.

3. Multi‑Axis Coordination for Hybrid Motion Systems

Next‑gen sequencing machines increasingly use coarse/fine stacked architectures:

• Long‑travel XY or XYZ stages for global positioning
• Piezo or voice‑coil stages for nanometer‑resolution focus control
• Rotational or tilt axes for optical alignment

Coordinating these systems requires:

• Deterministic multi‑axis synchronization
• High‑speed servo loops
• Real‑time sensor fusion (encoders, force sensors, vision)

This is where advanced control algorithms—like dynamic error compensation, ServoBoost, and adaptive control techniques—deliver real performance gains.

4. Force Control for Contact‑Sensitive Operations 

Certain sequencing platforms include contact‑sensitive processes such as:

• Probe‑to‑surface interactions
• Mechanical tissue dissociation
• Microfluidic cartridge insertion
• Soft‑touch engagement for optical modules

Closed‑loop force control —with soft‑landing, multi‑segment force profiles, and real‑time adjustment—prevents damage, improves reliability, and reduces consumable variability.

How Precision Motion Control Drives Better Sequencing Outcomes

• Higher Throughput

Faster, smoother stage motion reduces cycle time per imaging field or sensing location. High‑speed triggering enables rapid‑fire acquisition without sacrificing image quality.

• Greater Accuracy and Yield

Nanometer‑level precision improves:

• Base‑calling accuracy
• Signal‑to‑noise ratio
• Fluidic alignment
• Optical stability

This directly impacts read length, chemistry efficiency, and overall yield.

• More Stable, Reliable Instruments

Advanced servo algorithms compensate for:

• Mechanical imperfections
• Thermal distortion
• Structural vibration
• Encoder nonlinearities

Result: better performance without the cost of over‑engineered mechanics.

The Future of Gene Sequencing Depends on Motion

As genomic sequencing moves toward real‑time diagnostics, massively parallel architectures, and integrated multi‑omics, motion systems will become even more critical resulting in:

• Tighter integration of motion with AI‑driven image analysis
• Expanded use of multi‑DOF mechanisms
• Increased reliance on digital twins for stage and process simulation
• High‑speed synchronization between motion, imaging, and fluidics
• More robust force‑feedback and sensor‑fusion control

The genomics revolution isn’t just about chemistry—it’s equally about the machines that make the chemistry possible. Precision motion control is the silent enabler accelerating discoveries, improving data quality, and bringing the next generation of sequencing tools to market faster.

The post How Precision Motion Control Is Powering the Next Wave of Genomic Sequencing Innovation appeared first on ACS Motion Control.

In today’s competitive landscape, OEMs face constant pressure to shorten development cycles while delivering increasingly sophisticated motion‑control capabilities. Machine builders need the freedom to develop host applications using the tools, languages, and operating systems they already rely on—without compromising performance, usability, or reliability.

ACS Motion Control delivers exactly that.
With one of the industry’s most extensive sets of host application libraries (APIs)—spanning C, C++, C#, .NET, Python, MATLAB, LabVIEW, Linux, macOS, and low‑level socket interfaces—ACS enables unmatched development flexibility and dramatically reduces time‑to‑market.

APIs for Virtually Any Programming Language

ACS host application libraries provide a comprehensive ecosystem that supports all controller models, including the Controller Simulator, allowing engineers to write applications using their preferred development environments. These libraries include:

• C / C++ libraries
• COM and .NET libraries
• MATLAB and LabVIEW libraries
• Python libraries
• Linux and macOS support
• Low‑level TCP/IP socket interfaces

Beyond language flexibility, ACS provides rich built‑in callback options, user‑defined callbacks, and data‑collection capabilities—all designed to streamline host‑side machine logic and UI development. Sample projects included with the ADK Suite help teams get up and running fast.

Reduced Development Time Through Unified Tools

The real power of this multi‑language API suite becomes clear when paired with the MMI Controller Simulator. Developers can build and debug host applications without hardware, simulating motion responses, faults, and machine inputs in real time. This significantly speeds up feature validation and UI prototyping.

Engineers can:

• Develop and test host applications across C, .NET, Python, Linux, MATLAB, and more before hardware arrives
• Run full controller simulations with up to 128 virtual axes and 64 program threads
• Validate machine logic and visualization tools through simulated workflows

This approach dramatically reduces machine ramp-up time and the risks associated with integrating software late in the development cycle.

Compatibility That Scales Across Applications

Whether the goal is building a custom HMI, deploying real‑time data acquisition dashboards, or integrating complex motion logic into a factory‑level software suite, ACS APIs enable seamless communication with controllers over Ethernet TCP/IP.

Because the host libraries are standardized across all ACS controllers, machine builders can reuse code across platforms, reduce overhead in multi‑machine deployments, and maintain consistent UI/UX across product lines.

Focus on Performance, Not Data Pushing

With ACS handling communication robustness, event callbacks, and high‑level motion coordination, development teams can focus on what matters most—creating differentiated user interfaces and workflows that elevate machine performance.

Moreover, when combined with ACSPL+ for real‑time logic, engineers can offload time‑critical tasks to the controller while the host application handles visualization, orchestration, MES/SCADA communication, recipe management, and more.

Conclusion: Flexibility That Translates Directly to Speed

ACS host application libraries provide:

• Broad and deep multi‑language support
• A consistent API model across controllers
• A powerful simulator for rapid development
• Built‑in features that reduce coding effort and improve reliability

For OEMs building next‑generation semiconductor, electronics, laser-processing, biomedical, or precision‑automation equipment, this flexibility means faster development cycles, lower engineering effort, and shorter time‑to‑market.

With ACS, your software team can innovate faster—on the tools they know best.

The post Minimizing Time‑to‑Market with ACS: Flexibility Through APIs for Every Major Programming Environment appeared first on ACS Motion Control.

ACS addresses these challenges through advanced multi‑input multi‑output (MIMO) gantry control algorithms, designed specifically for high‑precision gantry architectures. These algorithms are a core part of Smarter Gantry Control technology and are powered by ACS’s multi‑axis servo processor architecture.

Why MIMO? The Limitations of Conventional Gantry Control

Traditional gantry control often relies on parallel single‑axis loops or MainDevice ‑ SubDevice architectures. While workable for basic motion, these methods struggle with:

• Axis‑to‑axis dynamic coupling
• Disturbances from one side exciting the other
• Mechanical compliance or yaw imperfections
• Performance consistency over large travel ranges
• Maintaining high bandwidth without risking instability

Even with advanced tuning, cross‑axis disturbances can degrade settling time, accuracy, and throughput — especially as payloads increase or the gantry structure becomes more flexible.

ACS’s MIMO Gantry Control: A Smarter Approach

ACS’s advanced MIMO algorithm directly addresses these issues by treating the gantry as a coupled multi‑axis system rather than independent linear motors. According to the ACS’s control team, Smarter Gantry Control is:

“Powered by unique, multi‑axis servo processor technology… advanced multi‑input multi‑output (MIMO) gantry control algorithms that simplify configuration and tuning while enhancing accuracy, throughput, and stability.”

This system‑level control strategy enables the controller to:

1. Increase Servo Bandwidth & Disturbance Rejection

MIMO control improves how the gantry responds to disturbances — including disturbances where motion on one axis induces error on the other axis.

This creates:

• Faster settling
• Lower position error
• Improved robustness across operating conditions

2. Maintain High Performance Regardless of Position

The MIMO algorithm provides “more consistent performance that doesn’t depend on stage axis positions,” especially important for large‑format gantry systems.

3. Enable Mechanical Error Compensation including:

• Dynamic cross‑axis compensation → higher throughput & accuracy à ability to sense influence or impact from another axis in a system and compensate accordingly to minimize overall system errors
• Dynamic error compensation → improved precision à ability to measure and compensate for inherent mechanical errors in real-time as motion systems move throughout their areas of work

This compensates for real‑world mechanical imperfections — yaw, compliance, load asymmetry — in real time.

4. Support a Wide Range of Gantry Architectures

The MIMO algorithm is designed for:

• Rigid & flexible‑yaw gantries
• Mechanical, air‑bearing, and hybrid gantry designs

5. Simplify Tuning with Advanced Tools

The MIMO solution is supported by the ACS FRF Analyzer, enabling:

• Rapid frequency response measurement
• Easier parameter optimization
• More efficient tuning & validation

Smarter Gantry Control in Advanced Applications include:

• Wafer inspection
• Laser processing & micro‑machining
• Electronics assembly & inspection
• Advanced packaging
• Precision metrology

These applications require:

• Sub‑micron and nanometer accuracy
• Tight cross‑axis synchronization
• High‑speed scanning motions
• Fast settle‑into‑tolerance moves

The Bottom Line: Higher Accuracy, Higher Throughput, Lower Effort

ACS’s Smarter Gantry Control with MIMO offers machine builders:

• Higher bandwidth & stability
• Better accuracy through dynamic compensation
• Faster cycle times due to improved disturbance rejection
• Simpler setup and tuning
• More consistent performance across the gantry workspace

By leveraging ACS’s multi‑axis servo processor and advanced control algorithms, OEMs can push their gantry performance to levels not achievable with traditional control approaches.

The post Smarter Gantry Control with MIMO: Unlocking Accuracy, Stability & Throughput appeared first on ACS Motion Control.

That’s where Real‑Time C Functions come into play providing a familiar programming language for advanced applications giving even greater flexibility and computational efficiency.

These capabilities, supported across ACS motion controllers, give machine builders the freedom to implement customized, high‑performance algorithms directly in C — executed deterministically within the controller’s real‑time environment. This unlocks new levels of performance, control sophistication, and IP protection that are simply not achievable with proprietary languages or traditional PLC‑style programming.

Why Real‑Time C Functions Matter

1. Execute Complex Algorithms at Deterministic Controller Cycle Rates

Real‑Time C Functions run inside the controller’s deterministic loop — even as fast as one controller cycle — enabling the implementation of advanced algorithms that must be evaluated with microsecond‑level precision. This is ideal for:

• High‑speed compensation
• Real‑time signal processing
• Complex machine logic
• Application‑specific control algorithms

These C‑based functions “can be executed on the controller in real‑time (e.g. 1 controller cycle),” ensuring no delay between computation and motion execution.

2. Combine Flexibility with the ACSPL+ Ecosystem

ACSPL+ already provides:

• Up to 10 kHz execution rates
• Up to 64 simultaneous real‑time buffers
• Easy motion/event synchronization
• User‑defined subroutines and interrupts

But when needed, ACSPL+ functions can seamlessly call C‑based functions for heavy‑duty computation or specialized routines. This highlights how engineers can “develop sophisticated algorithms efficiently with real-time C functions” and integrate them directly into ACSPL+ program flows.

This tight integration gives machine builders the best of both worlds:

• Rapid development using ACSPL+
• Maximum flexibility and computational efficiency using C

3. Accelerate Throughput with Custom Logic and Processing

Many high‑speed applications — such as laser processing, metrology, advanced packaging, and scanning systems — require per‑cycle decisions or corrections. Real‑Time C Functions allow engineers to embed application‑specific decision‑making and processing directly into the control loop.

These C functions can:

• Significantly increase process throughput
• Allow execution of “complex algorithms efficiently” directly in C
• Support rapid evaluation and debugging through ACS’s MMI Controller Simulator

By reducing the need for external controllers or host‑side computation, machines become faster, more deterministic, and more robust.

4. Protect Your Intellectual Property

Machine builders often view their algorithms as competitive differentiators. ACS supports this by providing IP protection, including:

• Encapsulation of C code
• Encryption of real‑time functions
• Optional password protection inside ACSPL+ programs

Real‑Time C Functions come with encapsulation + encryption = full IP protection, ensuring proprietary logic remains secure on customer machines. This is essential for OEMs deploying equipment across multiple regions and customers.

5. Develop and Test with Robust Simulation Tools

Both ACSPL+ and Real‑Time C Functions are fully supported by ACS’s MMI Controller Simulator environment. This lets developers:

• Test algorithms without hardware
• Validate real‑time execution behavior
• Debug safely and quickly
• Shorten development cycles

Putting It All Together: A More Capable Machine Architecture

Real‑Time C Functions expand what’s possible inside your ACS motion controller by enabling:

• Machine‑specific control loops
• Real‑time kinematics and transformation logic
• Filtering, compensation, and signal analysis
• Integrated process control unique to your domain

With the ability to combine these functions with ACSPL+’s multitasking environment, 10 kHz execution rates, and event‑synchronized motion, OEMs can build smarter, faster, and more flexible systems.

Conclusion

As machine performance requirements continue to escalate, the freedom to create deterministic, cycle‑accurate logic inside the controller becomes essential. ACS’s Real‑Time C Function support delivers exactly that: a powerful blend of speed, customization, and security — all within the trusted ACS motion control architecture.

Whether you’re optimizing throughput, integrating custom algorithms, or adding unique process intelligence, Real‑Time C Functions give you the tools to push machine capability to the next level.

Why Advanced Packaging Is Redefining Manufacturing

Advanced Packaging introduces new structural and process challenges that ripple across the entire semiconductor value chain. The move toward 2.5D, 3D, FOWLP, and FOPLP packaging reflects the industry’s need to deliver higher performance in smaller, more efficient designs. Today’s equipment must contend with:

• Smaller chiplets
• Thinner wafers/dies
• Finer pitches
• A higher number of pick‑and‑place points
• Increased connection densities
• More sensitive inspection and via‑creation processes

These challenges drive the need for faster, more accurate, and more flexible machine architectures—capabilities that motion control technology must enable.

Motion Control: The Backbone of Advanced Packaging Equipment

The brochure highlights ACS Motion Control’s approach to solving these next‑generation requirements through EtherCAT‑based motion controllers and servo drives engineered for virtually any packaging machine configuration.

1. Better Throughput

To keep up with tighter process windows and increased throughput demands, equipment builders require motion systems that can move faster and settle quicker.

ACS improves throughput using:

Smarter Motion = Competitive Advantage in Advanced Packaging

ACS Motion Control’s Value Proposition

Better Throughput + Higher Accuracy + Faster Development + Greater Flexibility = Smarter Motion. OEMs in the Advanced Packaging market rely on motion control innovations to overcome escalating design complexity, tighter tolerances, and accelerating production requirements. As chiplet‑based SiP architectures continue reshaping the semiconductor landscape, motion control becomes not just an enabling technology—but a critical differentiator for next‑generation packaging equipment.

The post Advanced Packaging Market: Unlocking the Next Era of Semiconductor Manufacturing with Advanced Motion Control appeared first on ACS Motion Control.

As Moore’s Law continues to slow at the transistor level, the semiconductor industry has shifted innovation “up the stack”—into advanced packaging. Technologies such as 2.5D and 3D integration, chiplets, hybrid bonding, fan‑out wafer-level packaging (FOWLP), and heterogeneous integration are now central to performance, power efficiency, and system scaling.

While much of the discussion around advanced packaging focuses on materials, interconnect density, and thermal management, an equally critical transformation is happening on the factory floor. Manufacturing processes are becoming dramatically more motion‑intensive, more precise, and more tightly synchronized than ever before.

This evolution is placing new and unprecedented demands on motion control systems, from nanometer-level accuracy to ultra-smooth force regulation and deterministic multi-axis coordination.

From Front-End Scaling to Back-End Precision

Traditional front-end wafer fabrication has long pushed the limits of precision motion—lithography, inspection, and metrology being the most obvious examples. Advanced packaging, however, brings those same precision requirements into back-end and mid-end processes, where motion systems historically tolerated looser tolerances.

Advanced packaging manufacturing now includes:

• Die-to-die (D2D), die-to-wafer (D2W), and wafer-to-wafer (W2W) bonding
• Thermal compression bonding  (TCB) and hybrid bonding
• High-density interposers and redistribution layers (RDL)
• Ultra-thin wafer handling and stacking
• Panel-level processing for higher throughput

Each of these processes introduces new motion challenges that differ fundamentally from conventional pick-and-place or wire bonding.

Key Motion Control Challenges in Advanced Packaging

1. Nanometer-Level Alignment Over Large Work Areas

Hybrid bonding and chiplet assembly require overlay accuracy well below 100 nm, often across large substrates or panels. This creates a difficult combination:

• Long travel ranges
• Ultra-high resolution
• Tight thermal and mechanical stability

Motion systems must maintain global accuracy, not just local repeatability. This drives demand for:

• High-resolution linear encoders
• Advanced error mapping and compensation
• Advanced multi-degree-of-freedom (multi-DOF) encoders and thermal compensation control algorithms
• Deterministic multi-axis synchronization

2. Force Control Becomes as Important as Position

In hybrid bonding and advanced die attach, excess force can destroy micro-bumps or copper pillars, while insufficient force leads to poor yield or electrical failure.

As a result, closed-loop force control is no longer optional—it is central to the process. Motion controllers must:

• Blend position, velocity, and force control seamlessly
• React in real time to contact events
• Maintain ultra-smooth force profiles during bonding and compression
• Support sensor fusion (load cells, strain gauges, vision feedback)

This represents a shift from “move and stop” motion profiles to continuous, adaptive motion behavior.

3. Coordinated Multi-Axis and Multi-Stage Motion

Advanced packaging tools increasingly rely on:

• Stacked motion stages (coarse + fine)
• Multiple gantries operating simultaneously
• Coordinated motion between wafer stages, bond heads, and inspection optics

These systems demand:

• Deterministic coordination across dozens of axes
• Sub-microsecond synchronization
• Advanced contouring and trajectory planning
• Minimal following error during complex motion paths

Any latency, jitter, or loss of determinism directly impacts yield.

4. Throughput vs. Precision: No Longer a Tradeoff

Historically, manufacturers accepted lower throughput to achieve higher precision. In advanced packaging, that tradeoff no longer works economically.

Equipment must now deliver:

• High acceleration and settling performance
• Short tact times
• Smooth motion to avoid vibration-induced defects
• Predictable cycle-to-cycle behavior

This is driving adoption of advanced servo algorithms, vibration suppression, feedforward control, and intelligent trajectory optimization—all at the controller level.

5. Ultra-Thin and Fragile Material Handling

Advanced packaging workflows often involve wafers thinned to 50 µm or less, or large glass panels with very low stiffness. Motion systems must:

• Minimize jerk and shock
• Support smooth, S-curve or higher-order motion profiles
• Actively suppress resonance
• Adapt motion parameters dynamically based on payload and process state

Here, motion smoothness is just as critical as raw accuracy.

Software and Architecture Shifts in Motion Control

The changes in manufacturing processes are also reshaping how motion control systems are architected.

Real-Time, Software-Defined Control

Advanced packaging equipment increasingly relies on:

• Advanced EtherCAT-based multi-axis motion controllers
• Deterministic real-time operating systems
• Tight integration with vision, metrology, and process control

This allows equipment designers to:

• Rapidly iterate process recipes
• Simulate motion behavior before hardware is finalized
• Tune control loops for specific bonding or alignment tasks

Simulation and Digital Twins

Given the cost of scrap and downtime, motion simulation is becoming essential. Controller-level simulators enable:

• Validation of multi-axis coordination
• Optimization of trajectories for throughput and smoothness
• Early detection of resonance or stability issues

For advanced packaging, this can significantly reduce time-to-yield.

What This Means for Motion Control Suppliers and OEMs

Advanced packaging is no longer a niche—it is a strategic battleground for semiconductor innovation. For motion control technology, this means:

• Precision alone is not enough: Controllers must combine accuracy, force control, determinism, and throughput optimization.
• Flexibility matters: Packaging technologies evolve quickly; motion platforms must adapt without complete redesign.
• Software differentiation is growing: Advanced algorithms, simulation tools, and open architectures are becoming key competitive advantages.

Motion control is no longer just an enabling subsystem—it is a process-critical technology that directly impacts yield, reliability, and cost.

Conclusion: Motion Control as a Yield Enabler

As semiconductor scaling moves beyond transistors and into packaging, manufacturing complexity is rising sharply. Advanced packaging technologies demand motion systems that are:

• More precise
• More responsive
• More synchronized
• More intelligent

In this environment, motion control is no longer hidden in the background. It sits at the heart of advanced packaging equipment—enabling the next generation of high-performance, heterogeneous semiconductor devices.

Read more in the ACS Advanced Packaging Brochure.

About ACS Motion Control ACS delivers advanced motion control solutions purpose‑built for semiconductor advanced packaging, helping manufacturers achieve higher throughput, greater accuracy, faster development, and more flexible machine designs. With industry‑leading servo algorithms, precise force and current control, scalable EtherCAT architectures, and powerful development tools, ACS enables reliable performance for increasingly complex SiP chiplet architectures, finer pitches, thinner wafers, and more demanding inspection and hybrid‑bonding applications.

The post Semiconductor Advanced Packaging appeared first on ACS Motion Control.

ACS Motion Control’s Laser Control Interface (LCI) directly addresses these pressures by delivering deterministic, position‑synchronized laser firing and power modulation across 2 to 5 axes. As laser processes evolve toward higher density, finer geometries, and complex multi‑axis coordination, LCI provides the trigger fidelity and temporal precision needed to keep pace with market demands.

Market Drivers: Finer Features, Higher Throughput, and Multi‑Axis Complexity

Across semiconductor and electronics manufacturing, the shift toward advanced packaging, micro‑interconnects, and heterogeneous integration demands increasingly fine laser features and higher process stability. Key laser‑processing application domains from your files include:

• TSV/TGV drilling, direct‑write lithography, and laser direct imaging, where consistent pulse placement and minimal thermal variation are critical.
• PCB/FPCB cutting and drilling, where multi‑layer stacks require precise depth control and synchronization between translational and rotational axes.
• OLED and micro‑LED fabrication, where uniform energy delivery prevents pixel‑edge damage at high process speeds.
• Glass, foil, and wafer micromachining, driven by consumer electronics miniaturization.

These applications increasingly involve multi‑axis contouring, complex spline‑based toolpaths, and smooth constant velocity throughout the entire process.

Why the LCI Matters: Deterministic Laser Firing at Sub‑Microsecond Latency

The LCI is designed specifically for position‑based and velocity‑dependent laser control, enabling precise energy placement even in high‑speed contour motion. Its capabilities include:

1. Sub‑microsecond latency

LCI delivers position‑based trigger outputs with extremely low latency and deterministic timing, ensuring each laser pulse aligns with the actual toolpath. This is crucial for multi‑axis processes where velocity can vary dramatically through corners or along spline paths.

2. Multiple laser‑activation modes for any contour

LCI supports a full suite of programmable modes:

• Fixed Distance Pulsing
• Segment‑Based Gating
• Coordinate Array Pulsing
• Distance Array Pulsing
• Coordinate Array Gating
• Distance Array Gating

These modes can also be combined internally for greater flexibility—an advantage for complex part geometries requiring selective pulsing or adaptive energy modulation.

View our LCI datasheet with the following examples and more.

3. Flexible power‑control formats

LCI offers PWM, analog, and digital power‑control outputs, enabling OEMs to interface with a wide range of industrial, UV, ultrafast, and fiber lasers. This versatility is essential given the market’s diversity of wavelength, pulse‑width, and power‑modulation requirements.

4. Consistency through speed variations

One of the persistent challenges in laser processing is scorching or over‑burning during speed drop‑offs (e.g., contour corners). LCI’s fixed‑distance pulsing maintains uniform spatial energy distribution, preventing damage even when axis velocities fluctuate.

Serving the Full Spectrum of High‑Demand Laser Markets

LCI’s feature set aligns directly with the needs of OEMs operating in:

• Semiconductor wafer processing (singe‑digit microns; TSV/TGV; interconnect drilling)
• OLED & micro‑LED display machining (thin‑film layers requiring ultra‑consistent energy)
• PCB/FPCB processing (multi‑layer, varied thickness materials)
• Automotive & aerospace components (precision metal cutting and welding)
• Biomedical device manufacturing (micro‑features and thin‑wall components)

As these industries push for more throughput and tighter tolerances, LCI provides the synchronization backbone that enables high‑speed, high‑density laser processing systems to scale.

Integrating Motion and Laser: LCI within the ACS Architecture

The LCI is part of ACS’s larger SPiiPlus motion‑control ecosystem, which combines:

• Universal servo drives supporting various motor and encoder types
• High‑bandwidth servo algorithms like ServoBoost for faster settling and reduced jitter
• Advanced profile‑generation tools such as XSEG and SmoothPath, enabling smooth, high‑speed contour execution with minimal error and reduced cycle times
• Real‑time programming via ACSPL+, ensuring deterministic coordination between motion profiles and laser events, even at 10 kHz program cycle rates

This architecture allows the LCI to operate not as an isolated laser trigger, but as an integrated, synchronous part of the motion system, ensuring that every pulse is placed exactly where the toolpath requires.

Conclusion: LCI as a Strategic Enabler in a Growing Market

The laser‑processing market’s trajectory is clear: higher density, more materials, tighter tolerances, and faster production cycles. ACS’s LCI directly aligns with these trends by offering:

In automation of high volume production processes – every millisecond of cycle time matters. As precision stages move faster and accuracy demands tighten, traditional PID‑based control schemes often become the bottleneck. ACS Motion Control’s ServoBoost algorithm directly addresses this challenge, providing a quantum leap forward in servo performance that translates into higher throughput by decreasing overall move‑and‑settle times while increasing overall system stability.

ServoBoost Addresses Limitations to Improve Throughput

1. Reduces Move-and-Settle Time

ServoBoost’s advanced compensation algorithms analyze system errors in real time and applies optimal corrective actions at high frequency.

• Stages arrive at target positions sooner
• Process tools (cameras, lasers, probes) engage earlier
• Short-move sequences (e.g., inspection, die attach, scanning) achieve higher cycle rates

2. Minimizes Velocity Error for Higher Constant‑Velocity Performance

For scanning, imaging, and laser‑processing applications, constant velocity is critical. ServoBoost significantly reduces velocity ripple, yielding smoother motion and allowing higher feed rates without degrading process quality.

3. Enhances Stability Across Frequency Ranges

Traditional servo loops struggle with mechanical resonances — especially large‑format stages and tools with cantilevered masses. ServoBoost identifies these resonances and automatically attenuates them to minimize effects on the system.  Additionally, ServoBoost also integrates seamlessly with complementary ACS features like MotionBoost, SmoothPTP, and Input Shaping, which further reduce motion‑induced resonances to increase throughput.

4. Reduces the Need for Extensive Manual Tuning

OEMs frequently struggle with tuning consistency from prototype to production systems. ACS explicitly highlights that ServoBoost helps address variability in system performance and reduces the burden on engineering teams. This makes scaling production faster and more predictable.

5. Improves Stability in High-Duty-Cycle Applications

ServoBoost’s real-time correction ensures stable performance compensating for mechanical wear, and variable loads over time.

Conclusion: A Simple Upgrade with Significant Throughput Payoff

ServoBoost represents a major advancement in servo control performance, and because it is easily activated in ACS motion controllers and drives, OEMs can activate these benefits without mechanical redesign.

For machine builders pushing the limits of speed and precision, ServoBoost provides:

• Higher throughput
• Improved accuracy
• Reduced tuning time
• More consistent performance across machines
