ABSTRACT:
A fixture supports and secures a printed circuit board ("PCB") during processing thereof. The fixture includes a frame for supporting the PCB and an attachable and entirely detachable bar or plate for securing the PCB in the fixture. A first opening is defined by the frame and is of sufficient dimensions to expose a first surface of the PCB. The plate defines a second opening, the second opening being of sufficient dimensions to expose a second surface of the PCB for processing. Spring-loaded latch assemblies connect the bar or plate to the frame at its ends or corners, respectively. The latch assemblies are simultaneously actuated by application of a slight pressure on the plate or bar. Simultaneous actuation of the latch assemblies ensures uniform application of pressure on the PCB, to avoid creation of a moment in the board. The latch assemblies do not require an operator's individual, repeated manipulation, but are actuated with a single application of slight pressure to the plate or bar.
