ABSTRACT:
The integrated shielding and mechanical support simultaneously addresses the problems of providing RF shielding for an electronic device such as a radio transceiver and providing a rigid mechanical assembly for the electronic device. Two conductive rails (120, 130) hold together multiple printed circuit boards (PCBs) (140, 160) having conductive layers (145, 165) to produce a four-sided shielding box (180) that protects certain electronic circuits on the PCBs from electromagnetic interference. An internal conductive shield (150) subdivides the inside of the shielding box to provide additional protection for sensitive circuitry. The shielding box inserts into an opening in a five-sided housing section (110) using guides (112, 114, 116, 118), which simplifies assembly of PCBs in the housing and facilitates automated assembly. A second housing section (190) attaches to the shielding box (180) once it is inserted into the five-sided housing section (110).
