We are fixing to run a board with both pb and pb-free BGA's..double sided.. The board is RoHs compliant so I could go either way on the solder paste. I was thinking pb-free paste would be the best bet. Any opinions would be greatly appreciated. Th

Will the Pb part handle 240C? That is the first question that you need to answer. If it will then yes I would run the pbfree paste and profile. I assume that all other components are pbfree. If not, the same questions will need be asked as for th

Any idea what the "industry standard" is for fall out on assembled PCB's? I realize that the controls put in place in your processes will effect your overall quality. But I'm trying for a general answer. On pre-tested assemblies, should you expect

Maybe I was not clear in my original post. So we have boards that have SMD components on one side and TH components on the opposite side. We want to assemble the boards using our SMT and Wave lines. Now the problem is that if we solder the SMD firs

Hi all, I would like to assemble boards that have one side all SMD and the other side all TH components. I have no idea how to do it. Any help will be appreciated.

There are several ways to assemble a board like you describe. Since you're asking this question, we assume that your production technology is limited. What tools, machinery, and equipment can you access?

Not an easy question to answer with out seeing the board. There is selective soldering, gluing, maybe a wave soldering pallet. As DaveF said since your asking the question I would assume your shops expertise is limited.

Thank you very much for your informative and helpful reply. I have a few more questions:) 1- So for the case 1: should I apply the glue to the PCB with the same method as I apply solder paste? (with screen printer and squeegee). If so, I would guess
