Outside the box: Can you retro your oven with a belt chain combo? I always order my ovens this way just in case. No pallet or carrier needed then. Can justify retro against the cost of the pallet or carrier. Two part epoxy instead of heat cure?

I found this pot, and tried adjusting it. It was already turned to its maximum, and the histogram did not look good. I tried replacing the board lamp and this helped the histogram a lot, but I am not able to get the bars centered in the green. The

Electronics Forum | Thu Jan 04 20:31:21 EST 2007 | Ben_T

Have you thought about an AOI system? With the system we have where I work, I'm able to run queries that'll tell me DPMO, yield, and pass/fail rates on a board level, part level, and opportunity level. Furthermore, this data can be broken down to see
