KaHrpr is correct. All of the extra 'redundancy' is waste in your process and will work against any goal of being lean. I would suggest establishing a team of individuals to do a C.I. project and conduct a PFMEA and try to determine where any holes

Ideal storage conditions to stop pcbs absorbing moisture is at less then 5% RH, for example in sealed moisture barrier bags. You mention that storage was at 40~70%...at these levels the pcb will absorb quite a bit of moisture. Your baking time was no

Thanks. If based on your statement, I can understand why it still can absorb moisture. But the PCB supplier was suggested us to keep at 40%~70% RH, if any issue occur with the storage condition of less than 5% RH, I think it is difficult for us to ge

The buyers in our company like to change the PCB finishing because of reducing costs. The proposed change is going from Ni/Au to HASL lead free, I know that in the beginning of the lead free period there where a lot of problems to use the HASL especi

When you say Fine Pitch is this .5mm or is it smaller? I wonder what problems they experienced with HASL, the only problem I recall hearing was the surface was not flat. When applying paste with a stencil I can not see how the flatness is an issue.
