Plastic Covers Offer EMI Shielding For Small Packages

For shielding cellular handsets, PCS and other small packages, CHO-VER SHIELD EMI shielding covers combine a slim profile, metallized plastic with a low closure force conductive elastomer gasket. The covers can be used to shield selected portions of a pc board, eliminating the need to shield a device's outer housing. Custom shaped CHO-VER SHIELD covers replace the use of solder-mounted metal cans over board components. The new covers provide 100 dB of shielding effectiveness at 500 MHz. Pins, holes and other locating features can be designed for fast, precise installation.
