One of the first lessons in quality management is the difference between quality assurance and quality control. Quality assurance focuses on eliminating defect opportunities before they occur, while quality control focuses on inspection strategies that eliminate defects before they escape the factory.

That said, use of automated inspection equipment has been growing dramatically in recent years because increasing density and complexity in printed circuit board assemblies (PCBAs) is driving the need for a blended quality assurance/quality control approach that includes mass inspection.
Over the past 18 months, SigmaTron International’s facility in Tijuana, Mexico, has been exploring the best way to automate inspection and integrate the captured data into real-time corrective action throughout its entire PCBA assembly process. In 2022, Industry 4.0 compatible automated optical inspection (AOI) technology was added in the SMT area. This year, customized Industry 4.0 compatible AOI equipment was added to secondary assembly.
