Electroless nickel/electroless palladium/immersion gold (ENEPIG) surface finish for PCBs has now become a key surface finish that is used for both tin-lead and lead-free solder assemblies. This article presents the reliability of LGA component packages with 1156 pads assembled with tin-lead solder onto PCBs with an ENEPIG finish and then subjected to thermal cycling and then isothermal aging.

Thermal via arrays under QFN components are used to conduct heat away from the device. However, thermal vias can create more voids or result in solder protrusion onto the secondary side. This paper discusses a study on the impact of via size and via design on QFN voiding and solder protrusion.
