Dear all, We haven't been using CPH (chips per hour) as an index of our production capability, but it seems more and more attractive as a basis by which we can compare the capability of different plants producing different products. Are there any o

Sounds like black pad to me. I just suffered this last week. Track your fab lot codes. Just in case. I processed 1000 fabs of 2 lot codes through 1 line (also WS609). 1 lot code failed with black pad the other did not. With one common mfg. proc

Finepi......., If you are going to use a naming convention where a 1206T1 has a height of 1mm why are you using 1206 instead of 3216T1. That is what it should be called to keep the mm across the house! That's just my opinion, I could be wrong!

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
