ABSTRACT:
A method and structures are provided for implementing enhanced reliability for printed circuit board high power dissipation applications. An external return current member provides a return current path outside of the printed circuit board, thereby minimizing power dissipation within the printed circuit board. The external return current member can be implemented with an associated stiffener formed of electrically conductive material. Alternatively, the external return current member can be implemented with a sheet of electrically conductive material with an insulator provided between the sheet and the associated stiffener.
