Are they visibly "popped" after wave but not before? Remember that many BGAs, especially plastic (PBGA) are very moisture sensitive and even 24 hours or less out of a controlled environment violates exposure rules.

No, but answer me this? 1 What type of BGA? 2 What's the wave process, materials and temps? Are you waving the BGA or top-side flowing it? 3 If the BGA is plastic, what are you doing to prevent/remove entrapped moisture before solder processing?

That should not happen. There are some threads concerning BGA and wavesoldering you could look for. It�s said that you should protect the vias in the BGA-area by soldermask or at least with tented vias to prevent rereflow of BGAs solderjoints what co

We have just completed some studies of with ABPAC, who is a large subcontract assembler of plastic ball grid arrays. BT laminates can pick-up appreciable moisture in just two hours. They are using TVP demoisturizing, our product (I apologize for the

It depends on the carbon polymer that the fabricator printed on your board. It could be: * No wave soldering * Wave soldering with a peelable mask * Wave soldering ... probably one of the latter two. Watch it. Some temporary masks can affect the
