Systems and methods for removing an adhesively-attached component from a circuit board assembly

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.

Mechanism to release cards and other components from computer

A lifting structure in the form of a release hook configured to conveniently and easily release computer components from their supporting structure by a simple pivoting action in response to lifting of thumbscrews. A typical computer component would be a PCIe card within a GPU tray. The lifting structure does not require the use of tools to release the computer components, and can be used where computer components ordinarily cannot be released by human fingers due to limitations of space. The lifting structure lifts the computer component to a height where the computer component can then be easily grasped by human fingers for removal of the component.
