Printed wiring board (PWB) for high amperage circuits

摘要

A printed wiring board (PWB) includes a substrate having first and second opposing surfaces and a busbar coupled to the substrate. The busbar includes a power input connector and a cross-sectional dimension configured and disposed to carry at least 100 amperes. At least one semiconductor device is mounted to the busbar. The at least one semiconductor device includes an input electrically coupled to the busbar and an output. One or more output conductors are electrically coupled to the output of the at least one semiconductor device. The one or more output conductors include a cross-sectional dimension configured and disposed to carry at least 50 amperes.

1. A printed wiring board (PWB) comprising:
a substrate having first and second opposing surfaces; a busbar extending through the substrate between the first and second opposing surfaces, the busbar including a power input connector and a cross-sectional dimension configured and disposed to carry at least 100 amperes; at least one semiconductor device mounted to the busbar at the first surface, the at least one semiconductor device including an input electrically coupled to the busbar and an output; another at least one semiconductor device mounted to the busbar at the second surface, the another at least one semiconducting including an input electrically coupled to the busbar and an output; and one or more output conductors electrically coupled to output of the at least one semiconductor device and the another at least one semiconductor device, the one or more output conductors including a cross-sectional dimension configured and disposed to carry at least 50 amperes.
