ALIO Industries Nanometer-Level Motion Control Systems Advance the Art of Micro-Electronic Testing & Assembly

(25th July 2023, Arvada, CO, USA) Precision motion control systems play a vital role in ensuring high quality and consistency in micro-electronic assembly and testing, particularly when it comes to accurate and repeatable positioning of test probes. ALIO Industries (an Allient Company) is at the forefront of innovation in this area, and is able to provide motion systems that meet the incredibly exacting requirements that are common-place in such applications.

In micro-electronic assembly, the components are incredibly small and delicate, requiring precise placement and alignment. Precision motion control systems, equipped with advanced servo motors and encoders, enable micro-electronic manufacturers to position test probes with micron-level accuracy, reducing the risk of misalignment and potential damage to the sensitive components. This accuracy is critical for verifying the functionality of each individual component and ensuring that they work flawlessly within the intricate circuitry of electronic devices.

In addition, micro-electronic testing demands a high degree of consistency to detect even the slightest defects or variations in performance. Precision motion control systems allow for repeatable positioning of test probes during testing processes, ensuring that each component is examined under identical conditions.

By minimizing positional errors, these systems enable reliable and consistent data collection, reducing the likelihood of false positives or negatives in the testing results. This level of consistency is essential in producing reliable electronic devices, as any deviation or inconsistency in testing could lead to faulty products and costly recalls.

Bill Hennessey, President of ALIO Industries says, “The scale of the components being manipulated when testing and assembling micro electronic devices is regularly on the order of micrometers requiring reliable positioning in the low two-digit nanometers. At such small scales, even the slightest inaccuracies in positioning can lead to faulty connections, misaligned components, or inaccurate test results. At ALIO, we innovate high precision nanometer-level motion solutions that can overcome the challenges of testing and assembling micro-electronic devices by employing advanced technologies and design principles. Our solutions incorporate  the most accurate linear motors on the market and high-resolution encoders to achieve nanometer-level positioning accuracy. Ironless linear motors offer precise and fast motion with outstanding responsive control at high bandwidths, ensuring that even the tiniest adjustments are made accurately. High-resolution encoders provide real-time feedback, allowing for closed-loop control and immediate correction of any positioning deviations.”

ALIO’s solutions also integrate sophisticated control algorithms and error compensation techniques to enhance accuracy further. Advanced control algorithms optimize motion trajectories, ensuring smooth and accurate movements. Error compensation techniques identify and correct systematic errors, such as thermal effects or nonlinearities, which can adversely affect positioning accuracy. By combining these technologies, ALIO’s high precision nanometer-level motion solutions can reliably and consistently address the challenges posed by microelectronic assembly and testing at such minuscule scales.

Hennessey continues, “ALIO’s rotary and linear motion systems provide high precision down to the nanometer level; excellent bi-directional repeatability, high levels of precision and accuracy, even after thousands or millions of cycles; fast response time, quickly responding to changes in position requirements, allowing for efficient and rapid testing and assembly processes; and minimal backlash ensuring that positioning remains accurate and consistent, even when changes in direction are required. As such, our precision motion control systems are indispensable tools in micro-electronic assembly and testing, guaranteeing the utmost accuracy and repeatability in positioning test probes and contributing to the overall quality and reliability of electronic products.
