Flux and Cleaning

The selection of flux and cleaning processes plays a critical role in the manufacturing yield and product reliability of electronic assemblies. The subjects of flux and cleaning are interrelated - one cannot be discussed without the other. The function of flux is to remove oxides and other nonmetallic impurities from the soldering surface and prepare a clean surface for joining. After soldering, cleaning may be required to remove flux residues.

BGA Reballing

When working with ball grid arrays (BGA), two of the most commonly asked questions are, "Can I reuse components?" and "How do I reball the components?"
