ALIO Industries nanometre-level motion solution
ALIO Industries is hoping to meet the requirements in motion system applications. Precision motion control systems help ensure high quality and consistency in microelectronic assembly and testing, with a specific focus on accurate and repeatable positioning of test probes.
Key information:
- Microelectronic assembly processes require parts to be placed and aligned precisely to reduce damage and misalignment of parts.
- Process motion control systems aim to improve accuracy levels through its ability to position test probes repeatably during the test process.
- ALIO Industries claims its nanometre-level motion solution can further improve quality assurance.
During the microelectronic assembly process, components tend to be small and delicate which requires parts to be placed and aligned precisely. Precision motion control systems with advanced servo motors and encoders, enable microelectronic manufacturers to position test probes with a high level of accuracy. This allows for the reduced risk of misalignment and damage of sensitive parts. With this level of accuracy, the systems can verify the functionality of each component.
Additionally, microelectronic testing requires high standards regarding consistency and the detection of defects and variations. Requirements that precision motion control systems meet due to the repeatable positioning of test probes during testing processes. With these high levels of accuracy, these systems can provide reliable and consistent data collection with a reduced chance of false positives or negatives. This level of consistency is required in the production of reliable electronic devices.
“The scale of the components being manipulated when testing and assembling microelectronic devices is regularly on the order of micrometres requiring reliable positioning in the low two-digit nanometres,” said Bill Hennessey, President of ALIO Industries. “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 nanometre-level motion solutions that can overcome the challenges of testing and assembling microelectronic devices by employing advanced technologies and design principles.”
He continued, “Our solutions incorporate the most accurate linear motors on the market and high-resolution encoders to achieve nanometre-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 claims to integrate control algorithms and error compensation techniques to further improve accuracy levels within its solutions. These algorithms aim to optimise motion trajectories to create smoother and more accurate movements. Additionally, error compensation techniques help by identifying and correcting systematic errors like thermal effects and nonlinearities, which can negatively impact positioning accuracy. ALIO combines these two technologies in its high-precision nanometre-level motion solutions to reliably and consistently address issues found in microelectronic assembly and testing.
“ALIO’s rotary and linear motion systems provide high precision down to the nanometre 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,” said Hennessey. "As such, our precision motion control systems are indispensable tools in microelectronic assembly and testing, guaranteeing the utmost accuracy and repeatability in positioning test probes and contributing to the overall quality and reliability of electronic products."
