Abstract
A dual-board host or main printed wiring structure of a circuit module with increased component mounting area is made plug-compatible with a VME or VME64X backplane to which single-board host or main boards may be attached with connectors of differing dimensions and pin configurations, the center line of which are offset from each other. The connection sides of the two boards are respectively bonded to a heat sink frame structure having a thickness which corresponds to the connector offset on the backplane such that the total thickness of one of the printed wiring boards, the heat sink frame and the two bonding layers with respect to board to connector center line distances equals the connector offset at the backplane.
