Shielding arrangement for electronic device
First Claim
1. An electronic device, comprising:
- a circuit board and an electronic component mounted to a first side of said circuit board;
a first frame composed of a molded material and secured around its perimeter to said first side of said circuit board, and comprising a plurality of longitudinally arranged rails and laterally arranged rails defining at least one closed perimeter that surrounds said electronic component on said circuit board;
a metal first cover portion carried by said first frame and closing said at least one closed perimeter, forming a chamber;
a layer of conductive material adhered to and covering an inside surface of said closed perimeter and said metal first cover portion;
a second frame, secured around its perimeter to an opposite side of said circuit board, and comprising a plurality of longitudinally extended rails and laterally extending rails at least partially defining a perimeter of said second frame; and
a metal second cover portion carried by said second frame and closing said second frame.

Abstract
A shielding arrangement for an electronic component mounted on a circuit board includes a shield formed by a frame sidewall arranged to be oriented upstanding from the circuit board and surrounding the electronic component mounted on the circuit board. A first cover portion substantially closes the surrounding sidewall, enclosing the electronic component on the circuit board. A conductive layer, formed by vacuum deposition covers an inside surface of the surrounding sidewall and an inside surface of the first cover portion, continuously. As an alternative to the conductive layer, the frame can be composed of an electrically conductive plastic. The first cover portion can be a stamped metal plate integrated with the frame by overmolding.
