There are a host of possibilities. Virtually any fabrication process prior to outer layer manufacturing prior to HAL could contribute to dewetting. That goes all the way to excessive brighteners in the copper plating line. Anything that prevents the

Hi, all. There is one 0.8mmX0.8mm QFN on almost of our PWBAs. But the quality report showed that we got bad solder quality for this component. My question is which elements are the root cause for this situation frequently? Thanks.

What I have seen too is that these parts normally come in a tube and from moving in the tube some of the copper starts to expose and solder will not adhere to these parts. Let me know if anyone else sees the same problem.
