Unfortunately nothing ground breaking to report. The board shops analysis (SEM/EDS)showed high levels of carbon and oxygen, likely indicating an organic based contaminate. They are still stumped on where it is coming from. We recieved some boards y

On the bare boards, no paste, just a bare FAB board. We get them from a PWB manufacturer and inspect them to IPC-A-600 and then ship them to another manufacturer to populate them and we then inspect them to IPC-A-610. I have written several program

The SimmScope is an first article inspection system that uses an overhead digital microsope on a motorized gantry to inspect the board - much like an AOI - except that it does not automatically make the pass/fail decisions. It is up to the operator t
