Head-in-Pillow (HiP) soldering defects are common with modern SMT component placement. As a result, Practical Components has introduced the PBGA 928-HiP, a component that is designed specifically to be susceptible to HiP defects. It features a large 4x4 body size, 928 balls and a single small die that has a propensity toward the ball-in-socket HiP soldering defect.

C-mode scanning acoustic microscopy (C-SAM) is a non-destructive inspection technique showing the internal features of a specimen by ultrasound. The C-SAM is the preferred method for finding “air gaps” such as delamination, cracks, voids, and porosity. This paper presents evaluations performed on various advanced packages/assemblies especially flip-chip die version of ball grid array/column grid array (BGA/CGA) using C-SAM equipment. For comparison, representative x-ray images of the assemblies were also gathered to show key defect detection features of the two non-destructive techniques.
