Colleagues,

We have to find a way to replace solder balls on small quantities of BGA
devices, and I wonder what is available on the market.  There might be just
one unit or up to perhaps fifty units per lot.

The BGAs are of various sizes, and pitches, and ball sizes.

Is there a machine which can do this job for us?  Can you suggest
manufacturers names, and give a guess at the price range.

Are there subcontractors who offer a ball replacement service - and fast
turnaround?  Again I would be grateful for any pointers from those of you who
have experience of this work.

TIA....

Tomaso
