How about this scenario: Need to rework a BGA on a 2 year old board. Originally the board was assembled with Sn63/Pb37 and the BGA has eutectic spheres. Now this package only comes with lead free balls. I believe that the board finish is not idea

Hello All, I recently had a case of excessive tin coming from a solder pot sample. The solder is SN63 but the results of testing had a 64.97% for Sn. The J-STD-001 spec is 61.5% to 64.5%. The pot is used to pre-tin wires which will then be solder

In switching to lead free processing, we find ourselves having over 400 PCB part numbers with Sn63 HASL finish. And there is no hope of quickly purging inventory and getting our drawings changed to call out a lead free finish. I want to avoid having
