Ceramic Column Grid Array (CCGA) packages are becoming increasingly popular as an alternative to Ceramic Ball Grid Array (CBGA) packages for applications requiring very high-density interconnections with higher board-level reliability. CCGA packages use high-temperature solder columns instead of balls which create a greater standoff, providing a flexible interconnection with improved thermal fatigue life of the package solder joint. This paper introduced a technology featured a palladium addition to the 63Sn37Pb solder on the column-to-component pads which formed palladium-tin intermetallics that did not melt during initial the printed circuit board (PCB) assembly and added additional strength to the solder joint.
