ABSTRACT:
A printed wiring board file arranged to mount printed wiring boards in an efficient manner while simultaneously providing for the convection cooling of such boards. The boards include components of varying heights. Each printed wiring board is supported by a connector at one side edge and a printed wiring board guide at the opposite side edge. Each board guide includes two sets of grooves which allow it to be used as a guide for the left or right sides of the boards. The first set of grooves is used when the board guide supports the left side of the printed wiring boards and the second set of grooves is used when the board guide supports the right side of the printed wiring boards. The grooves are formed in the board guide at a vertical spacing less than the minimum permitted vertical spacing for the printed wiring boards. Multiples of the groove spacing are selected to mount printed wiring boards with a minimum or greater than minimum spacing.
