Automated optical inspection (AOI) and automated X-ray inspection (AXI) have been around for some time in various configurations and both have played a role in improving the quality of circuit boards.
The use of AOI (automated optical inspection) systems with dual-lane configurations is increasing in high-speed PCB (printed-circuit board) assembly, due to the systems’ ability to double capacity in ...
One high-volume OEM proves that even simple feedback from an AOI system can reduce end-of-line defects by an order of magnitude. Until recently, the use of pre-reflow optical inspection usually was ...
