When it comes to F1 AOI (Automated Optical Inspection) machines, there are various models and manufacturers available on the market. While specific features and capabilities may vary between different F1 models, here are some general factors to consi

Bingo!!! By panelizing and adding breakaway rails (as Nancy says), Stuart can pour copper up to his board fab's tolerance from the board edge. Traditionally, he just wants to make sure no copper shows on the edge of the board. Then again, it's his

If you are not placing any parts that need special attention ( BGA, CCGA, etc... ) on topside then it should be fairly easy to create a profile that will work for you. If you are wanting to use the profile you currently have for topside I am not sur

We have evaluated 4 different AOI machines and the General Scanning 8200 machine was the best. Great G R&R. As far as paste height goes, it is very paste dependant. I recently completed a DOE comparing laser stencils to EFab, varying 0.5 mm pitche
