  • Systems and methods for removing an adhesively-attached component from a circuit board assembly
    Patent number: 11553631
    Abstract: Apparatus and associated methods relate to removing an adhesively-attached component from a circuit board assembly. A complementary pair of high-permeability members are positioned on opposite sides of the circuit board assembly about the adhesively-attached component. Then, a magnetic field is induced within the complementary pair of high permeability members via a coil driver generating an AC current in an inductive coil circumscribing a central pedestal of the complementary pair of high-permeability members. The magnetic field induced is directed through the adhesively-attached component via a central pedestal located proximate the adhesively-attached component. A return path for the magnetic field is provided about a periphery of the adhesively-attached component via a peripheral pedestal.
