You also need to get with the PCB manufacturer. Their is a lot that can go wrong with that many layers. If the manufacture is trapping that much moisture. you may have a hard time baking it out. Dave and Graham are right about the time and energy. It

We have experience with this alloy, but with enig and we did start with PB HASL, none of our PCBs would of course pass thermal cycling at normal temperatures with the HASL so we went to ENIG. we could thermal cycle at 100-115C with no issues. We foun

We have been struggling for a while with some through hole sealed mechanical relays that fail at test after they have been sitting a while. They will initially pass test, but seem to fail if they sit for a few days. We made sure our wave process was

Can anyone tell me that between Mirtek & Kohyoung which AOI machine will be better and why?

Electronics Forum | Thu Feb 12 21:14:37 EST 2015 | kahrpr

They are both very good machines however Kohyoung will give you better first pass results meaning a lot less false calls and when you run the first board after initial programming you have to fix very few things. However the cost is a lot more. This
