Just send it to me, I'm confident I can do it here.

Tony: What kind of QA controls do we have for optical inspection?

Production lines here in Germany usually have _really_ high resolution
CCD cameras and pattern matching software to detect stuff like missing
components.

Something like a bent contact on a connector is probably only detected
safely by an electrical test.
