Does anyone know what are the available type for LF solder balls? I only know LF35. Is there any other types besides this? Does anyone have the data for the hardness of SAC type and LF type solder ball? Many thanks in advance

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

What type of solder ball defect that you want to avoid is it voids or misregistration or ball-pad adhesion. Cemal Basaran

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

Not an unusual problem, especially for nc flux users. Search the fine SMTnet Archives for background.
