Abstract

A metal electronic package is provided having improved electromagnetic interference shielding. Metal base and cover components are electrically interconnected to remain at same voltage potential thereby reducing EMI induced mutual inductance. An electrically conductive conduit, such as a contact pin, provides interconnection. If the electronic device is mounted on a chip pad attach, the conductive conduit also connects to the support pads of the chip attach.
