The ball-attach process for BGA and PGA packages uses a flux that is usually applied via pin-transfer from a dipping tray. Solder spheres (solder balls) are then placed into the deposits and the whole assembly is reflowed. BGA fluxes are usually water soluble, while PGA fluxes are often very reactive no-clean materials.

The ball-attach process can be considered a trivial step when creating an FCBGA or similar package, but the final soldering step can be rather complex. There are several variables that impact the final ball-attachment from the number of assembly processes needed before. These processes can be…
