    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.

    This place sells reballing kits

    I have not personally used them.

    Kit Contents:
    Vial of 50,000 Solder Balls.
    Choice of 20 mil, 25 mil or 30 mil solder spheres.
    Choice of Sn63/Pb37 or Sn10/Pb90 solder alloy.
    1 standard stencil (component specific).

    Hope that helps.

    Thanks for the info. But it really didn't help me because they
    don't sell the 12mil balls that I need. They also don't list any
    prices, or apparently, any way to actually order their products.
    I often wonder how companies like this stay in business.

    Anyway, I ended up buying the solder balls I needed from
    I paid about $80 for 20,000 12mil 63Sn37Pb solder balls.
