Features, Applications
The Leading Source for EMI Shielding Reliable Board, Enclosure and Cable Solutions

Shielded enclosures for RF radiations from PCB components stop RF energy right at the source, eliminating re-radiation and interference with other nearby components as well as reducing the number of other shielding expenditures such as filters, gaskets and RF hardening of the equipment exterior structure. The addition of a frequency-tuned absorber membrane layer adds unprecedented performance, assimilating radiated energy without relying on repeated reflections from the interior surfaces of the shield, and without problems of harmonic resonance. Refer to sketches at right.

Typical shielding approach allows reflected radiation to affect neighboring components.

The versatile shield design includes a solderable fence and tight-fitting cover assembly of copper alloy (C77000), a tough solder-compatible material which does not require plating nor has corrosion prone bare edges. The removable cover provides convenient access to circuitry; and is very cost-effective due to the use of universal multi-use manufacturing tooling.

RF absorber approach assimilates radiated frequencies and converts to imperceptible heat energy. Specific frequency-tuned absorber material is bonded toRF the Absorber lid interior. Shield A wide range of EMC and Microwave absorbers can be specified from 40 MHz to 116 GHz.

Each enclosure shield size can be combined with frequency-specific absorber material bonded to the cover interior for exacting remediation of otherwise errant frequency emanations - a selection of five EMC absorbers effective from 50 MHz to 1 GHz along with an extra wideband version effective from 40 MHz to 5 GHz; and, ten Microwave versions effective to 116 GHz.

PCB Shield effectiveness can be further RF Absorber Shield enhanced by adding RF absorber material under PCB (see pages 30-34).
