Abstract
A unique housing (104) or a portable radio transceiver (100) is described that includes unique metal printed circuit panels providing for grounding and heat sinking of electrical components and circuitry thereon, and a battery as a structural element thereof. In one illustrated housing (104), three printed circuit panels (212, 213 and 214) and a stick battery (210) are held together by interlocking side rails (206,207). The unique printed circuit panels (212, 213, and 214) include mesas (422) that protrude through corresponding holes in the dielectric and circuitry layers (404 and 406) laminated on the panel. The mesas (422) are preferably soldered to the circuitry layer or electrical components thereon. The shape and size of the mesas (422) can be varied to provide the desired grounding and/or heat sinking. The unique metal printed circuit panel of the present invention may be advantageously utilized in a variety of applications including battery-operated radio transceivers, such as, for example, cellular radiotelephone systems and trunked radio systems.
