A printed wiring board is adapted to be mounted to a chassis using a fastener. The chassis provides an electrical ground for the printed wiring board. The board includes first and second sides and a mounting aperture extending therethrough for receiving the fastener. A plurality of spaced apart solder pads are disposed on one side of the board and adjacent to the mounting aperture. The pads are adapted to provide an electrical connection to the chassis. At lease one aperture is disposed in each of the plurality of pads. The aperture is plated creating an electrical connection between the sides of the board.

In a modular power supply having a plurality of module slots capable of receiving power supply modules therein, a system and method for controlling the power supply modules to regulate an overall output characteristic of the modular power supply, including: (1) an overall control circuit for sensing an overall output characteristic of the modular power supply and developing therefrom an overall error signal representing a deviation of the overall output characteristic from a reference characteristic and (2) a separate module control circuit for each of the power supply modules, each separate module control circuit sensing an output characteristic of an associated power supply module and developing therefrom and from the overall error signal a regulating signal for the associated power supply module, the regulating signal controlling the output characteristic of the associated power supply module to control the overall output characteristic of the modular power supply.
