Hello, need some help if anyone has any insight on this issue. Ran first side and ex-ray indicates BGA parts look normal. Ran the second side and now the BGA balls on first side appear to have broken free and moved under part. This board has BGA's

Good Morning JM, Does anything come into physical contact with the BGA in question during the reflow event? Is this a RoHS process? If so, is the BGA in question also a RoHS part? Thanks Chris

Head-in-pillow (HiP) is a BGA defect which happens when solder balls and paste can't contact well during reflow soldering. Package warpage was one of the major reasons for HiP formation. In this paper, package warpage was measured and simulated. It was found that the package warpage was sensitive to the thickness of inside chips. A FEM method considering viscoelastic property of mold compound was introduced to simulate package warpage. The CTE mismatch was found contributes to more than 90% of the package warpage value when reflowing at the peak temperature. A method was introduced to measure the warpage threshold, which is the smallest warpage value that may lead to HiP. The results in different atmospheres showed that the warpage threshold was 50μm larger in N2 than that in air, suggesting that under N2 atmosphere the process window for HiP defects was larger than that under air, which agreed with the experiments.

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
