9.0 BGA Component Rework and Reballing Procedures

The guides in this section provide comprehensive procedures for BGA component rework and reballing on circuit board assemblies. It covers process flow and inspection guidelines for both reworked and reballed components, as well as profile development using standard or Smart Track methods. Detailed rework techniques address component removal, solder ball removal (via braid or robotic methods), and reattachment using mini-oven or reflow oven processes. Special procedures are included for machining removal of BGAs installed with non-reworkable underfill. Each method emphasizes proper thermal profiling, inspection standards, and handling practices to maintain solder joint integrity, component functionality, and overall assembly reliability.
