Comparison study on reliability performance for polymer core solder balls under multiple reflow and HTS stress tests

Drop ball reliability for Ball Grid Array (BGA) package on lead-free product is a major reliability concern. Integrating a polymer core in the solder ball could be a good strategy to dissipate stress better compared to the purely metallic solder ball. However, the diffusion rate of the copper is muc...
