I am looking for a vendor for solder spheres and tack flux for BGA reballing. Preferibly on the east coast or new england area. My current distributors have them but require a min purchase of 200,000 that's a lot of balls!!!! thanks greg

Can anyone recommend ways of reducing damage to solder masks ... a new wick perhaps. I find that using standard wicks the imposed damage is un-acceptable. Also any good links on the subject of bga rework would be really appreciated in earnest ...

Here's what I do: - Test Surface Insulation Resistance (we're in the high reliability market and use a test significantly harder than IPC's). I also test SIR in combination with other assembly materials like conformal coatings and wave solder flux

For the most part there would not be a lot of change over. There are two primary boards at this time that would be run on the line that also use common components. At this point all but a couple of the pick and place machines we have looked at have t

I have nothing to add technically but we have been washing no-clean for years. Use very clean filtered DI water to avoid the white residue issue and some good detergent or sopanifier and you will get great results.
