42 SMT007 MAGAZINE I AUGUST 2026 C omponent rework is the controlled process of removing, replacing, repositioning, or repairing electronic components on an assembled PCB. Rework may be required because of component defects, incorrect place- ment, soldering defects, engineering changes, or damage identified during inspection or testing. A successful rework process uses controlled heat- ing, soldering, cleaning, handling, and inspection techniques to restore the assembly while minimiz- ing thermal and mechanical stress to the PCB and surrounding components. Common Rework Methods Although several methods may be used to rework PCBs, hot air and infrared systems are among the most common for area-array and surface mount components.
