High temp balls (spheres for you PC types) They are non-eutectic balls. Do you have a reballer or stencil setup? If one device...may not be cost effective, but if many you can usually send back the the IC house for re-ball. There are only a handf

A small benchtop system uses a mask, tooled for your part, to arrange the solder spheres onto the BGA, after it has had the excess solder heat-vacuumed off and a new layer of flux applied. The spheres are poured into the cavity, excess decanted off.

Have you looked at solderquik? Winslow Automation sells them. I've had good luck with them. They are bga preforms with the balls on a water soluble paper.

I believe that solder paste will need to be applied to this part. I have re-balled these in the past in a low volume situation and here is what I did and there appears to be no adverse effects to the component. Get a stencil (I use 8 mil for .032"

CBGA devices are a bit trickier to reball than run of the mil plastic devices. Once assemblied they are a bit like a sandwich when fitted to a PCB. From top to bottom it goes BGA device - Eutectic solder - High temp solder ball - eutectic solder -

Does anyone have any experiences with bga reballing. When I had reworked failed bga part with new part It was good. So I tried to reball bga detached but failed . I guess the cause of fail is thermal shock. IS IT OK TO REBALL BGA PARTS DETACHED ?

Contact practical components, they have masks and balls, I would not call it automated though. These are simply placing the mask over the part and dumping the balls on it then removing (brushing)the excess balls. I have run and reballed BGAs with ou

Hi Russ, Thanks for the suggestion. I have the practical components sets that you mentioned, they take too long to do 10 pcs, the "pre-forms" are much faster. What equipment do you use for your automated process?
