A Novel Approach to Experimentally Create and Mitigate Head-in-Pillow Defects
One of the solder joint failures encountered frequently during Printed Circuit Board Assembly (PCBA) is due to Head-in-Pillow (HiP) defects. The primary cause of HiP defect is due to the warpag

Effect of Lead-Free Alloys on Voiding at Microvia
For SnAgCu solders,the voiding rate at microvia was studied with the use of simulated microvia,and was the lowest with
95.5Sn3.8Ag0.7Cu and 95.5Sn3.5Ag1Cu. The voiding rate increased with decre
