Head-in-Pillow BGA Defects Head-in-Pillow BGA Defects. Head-in-pillow (HiP), also known as ball-and-socket, is a solder joint defect where the solder paste deposit wets the pad, but does not fully wet the ball. This results in a solder joint
Leaded and Lead-Free Solder Paste Evaluation Screening Procedure Leaded and Lead-Free Solder Paste Evaluation Screening Procedure Numerous studies have shown that greater than 60% of end of line defects in SMT assembly can be traced to solder
Defect Free QFN Assembly Defect Free QFN Assembly The problem with soldering QFN packages is that they float, skew and tilt on the 'domed' melted solder during the SMT re-flow process. This floating, skewing and/or tilting will lead to solder
