ABSTRACT:
An assembly is provided for uniformly applying pressure to a selected portion of a circuit board mounted between spaced surfaces. The assembly includes a retainer for selectively applying pressure to a proximal surface of the circuit board and a stiff U-shaped bar having a channel in which the retainer is mounted, the bar thus being interposed between the retainer and the circuit board. Preferably, the retainer includes at least one member that is attached to the bar by a snap-in fit. When the retainer is actuated, the bar is pressed against the circuit board, thereby causing the opposite surface of the circuit board to uniformly press against a housing slot wall. A side wall of the bar preferably contacts a wall of a slot in which the assembly is mounted to enhance heat transfer. The retainer preferably has members of minimal size contacting the bar to enhance uniformity of pressure and preferably has an internal channel in intermediate retainer members, which channels are only large enough for an actuator rod to pass therethrough.
