Im looking for equipment that can attach solder balls between the size 15-25 mils to the leads of a land grid array. There is also the posibility of attaching balls before leads are inserted into the socket. This is a little differant than attaching

also the balls need to be lead free, just to make it more interesting.

The paper Dave posted the link for is great. I have to go back and read it in depth. I can build prototypes by wirebonding to ENIG. I can do it on a manual wirebonder but I don't have the patience to do it on a magazine to magazine automatic machi
