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

Sounds like the boards were not properly manufactured since you have baked them prior to assembly. We just had a customer return from China becasue of this issue. We have made 10K without issue. Let me take a stab and ask if they were made in the USA

we encounter the same problem as you 3 years ago. but now we have implement to use KIC 24/7. you just need to take 1 time profile (for the base line profile), and then for the next time you run your product, it will take profile for each board you b

KIC 24/7 has evolved into RPI. Not only will it give you virtual profiles, it also gives you DPMO and yield, based where each board lands in the process window. The good thing about this software, you can go back a year later and look up a specific

Well their demo was interesting. We're an OEM with our own product line, so the part numbers don't change much and we don't cross things often. It seems like it might do what I need for the next few years. If you're selling to upgrade, out of curios
