ABSTRACT:
Components such as IC's mounted on a substrate such as a PCB are removed from the PCB in a heating apparatus. The heating apparatus has a mounting frame which positions the PCB above an array of infra red heating sources. The method includes the steps of bombarding the PCB with infra red energy which is absorbed and conducted to the solder joints to melt the solder to permit extraction of the components.
