System, method and apparatus for pulsed induction heat removal of components from structural assemblies

摘要

A pulsed induction heating system removes bonded elements from underlying substrates. A coil loop of a tool fits around the base of the clement to be removed. The tool heats the element and the substrate in short pulses that are followed by brief, non-heated wait periods. The temperature of the substrate is measured during the wait periods between pulses to avoid overheating. When the substrate reaches a target temperature, the adhesive is sufficiently softened such that the element and adhesive are readily scraped off without damaging the substrate.
