Product Introduction
Rework stations repair misplaced or defective components. Hot air tools desolder parts without damaging PCBs. BGA reballing requires precise temperature control and alignment jigs. Challenges include pad oxidation and thermal stress on adjacent components. J-STD-001 defines acceptable rework criteria. X-ray inspection verifies hidden joint integrity after repair. Nitrogen-assisted reflow minimizes re-oxidation. Training operators in IPC-7711/7721 standards is critical. Advanced systems use laser heating for localized rework. Rework logs ensure traceability for automotive/aerospace sectors.
