I need to reball some BGAs with Pb37/Sn63 solder balls. I need about 10,000 balls. Does anyone know where I can buy them? I found a few places selling lead-free solder balls, and a few places that sell solder balls by the millions, and several manufacturers that don't sell direct. But I can't find anyplace to buy a small qty (~10k) of PbSn solder balls. Thanks for any info.
Some of the BGAs are 1mm pitch, but most are 0.5mm. So I need two sizes of balls.
Btw, I have never actually reballed a BGA before, so if anyone has any pointers about good techniques, let me know. I am going to practice on the cheaper chips till I figure out what I am doing.
