Baking boards, especially multi layer, will help with blowholes and delimitation, but not with solder balls. Normally about 120c for 1 hour or so is sufficient. I usually will not go to this trouble unless a board has proven to be a problem or if th

We just got a lesson on the effectiveness of heat sealed metalized vapor barrier bags. A customer sent us two bags of 100% saturated PBG components by air freight. This was for a demoisturizing test. When we found the devices 80% dry when they arrive

Sal: If it�s not the PCB, what about the connector itself ? Is it from a different production lot with some unregularities ( dimensions, tolerances, pin alignment, material weakness)? How about handling, storage, shipping causes ? Could it be a tooli

I just started an analysis concerning broken capacitors (0603 ceramic). My first question concern the standard used to determine the maximum force a capacitor 0603 can support on a pcb. Some capacitors suppliers use the die sheer test of MIL-STD-883
