Abstract:

A captive screw for use in electronic assemblies includes a screw with a shaft having a pair of spaced grooves and a cover captivating the screw and for attaching the captive screw. A knob for rotating the screw can be moved along the shaft between an extended position and a lowered position corresponding to the grooves on the shaft, and releasably locked to the shaft in either position. A lock wafer is used to secure the knob to the shaft. A release button with a large head actuates the lock wafer.

Abstract:

A hand operable tool is provided for removing a memory module printed circuit board from an underlying processor board without an appreciable risk of bending the pins of the pin-and-socket connectors used to removably secure the circuit board to the processor board. The tool comprises a generally inverted U-shaped outer frame structure having a pair of parallel, inturned bottom pressure plates secured to its lower ends. A shorter, generally inverted U-shaped inner frame structure is slidably retained within the outer frame structure and has a pair of parallel, inturned upper pressure plates secured to its lower ends. The inner frame structure is spring-biased to a lower limit position in which the upper pressure plates engage the bottom pressure plates, and a pair of elongated upper and lower handle members are connected to the frame structures. To remove the circuit board, the pressure plates are positioned beneath opposite underside edge portions of the board and the tool handles are vertically squeezed toward one another to vertically separate the upper pressure plates from the bottom pressure plates. This causes the bottom pressure plates to bear against the processor board, and the upper pressure plates to simultaneously bear against the underside edge portions of the circuit board and vertically lift them to remove the circuit board without bending its associated connector pins.
