I am re-designing a MLB Printed Circuit Board which has thro' hole chips and a BGA. I am planning to go for reflow soldering for the BGA on one side and wave soldering for the thro' hole parts on the opposite side. Is there any concern or any sequenc

Hi, Reliability was what I was worried about. We have not shipped these yet, as we are not sure about reliability. We can ship them in regions outside of the EU anytime so we are ok on that, and because of supply chain delays, we are already shippi

Being in the line of BGA rework and having performed much rework on boards that go into military planes, I can give you an opinion from a practical background rather than an in depth study. Basically BGA's have caused many of my customers big headac

I have a product with mixed in Pb free and Pb BGAs. I decide to use SnPb paste with Pb free reflow profile to make it work for both types of BGA. Do I have a reliability solder joint issue by using this method? How is your opinion on this case? Can

We all know those academic 'reliability studies' are very focused and only give a snapshot of real life. The real reliability studies of leadfree are starting as we scramble to meet our numbers. We have no idea about your customers' expectations ab

I have used both immersion silver and immersion gold and found that the immersion silver performed better in reliability studies for BGA's using 63/37 paste.

What does your customer want you to do? I would not want a CM soldering one of my boards with leadfree paste if I didn't ask him to. Whatever you do, get approval first. Two things to consider: If the other components are not rated for leadfree tem
