Abstract
A circuit board clamp includes a clamp frame having a first and second frame supports. The clamp frame also includes a top plate arranged between the first and second frame supports. The top plate supports a piston via a threaded fastener engaging a top plate aperture. The piston may be displaced relative to the top plate in accordance with adjustment of the threaded fastener. A pressure plate assembly has a pressure plate and a stem attached to the pressure plate. The stem is positioned within a tubular section of the piston, and the pressure plate is positioned opposite the circuit board from the heat sink. The pressure plate contacts a surface mounted integrated circuit between the circuit board and the pressure plate. A bias member is seated on the bias seat and applies a biasing force on the pressure plate.
