Pb-free flip-chip bga
Splet08. sep. 2006 · Because of the higher level of process-induced voids in Pb-free solders, this debate is more intensified in Pb-free joints. This study presents finite element analysis (FEA) of the influence of void size, location, and spacing on the durability of Pb-free solders. SpletAccordingly, Pb-free flip chip packages should have an additional reliability issue that is not a concern for Pb solder packages. In this paper, a typical flip chip package is modeled to quantify the impact of the volumetric …
