The paper will be presented by Nihon Superior�s Senior Technical Adviser, Keith Sweatman on Monday, March 10th.
Since the electronics industry first became aware that it would have to change to lead-free soldering technologies to meet the requirements of the EU�s RoHS Directive, there has been concern about criteria for the selection of alloys to replace the tin-lead solder on which the industry has previously relied. The paper being presented reports the results of impact fracture energy testing of a Sn-Cu-Ni lead-free eutectic alloy compared to a Sn-Ag-Cu alloy for BGA spheres.
