The Leading Source for EMI Shielding
Reliable Board, Enclosure and Cable Solutions
PCB shielded enclosures with RF absorbers
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.
RF Absorber Shield
modular fence and cover design
The versatile shield design includes a solderable fence and tight-fitting
cover assembly of copper alloy 770 (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.

custom tuning to the exact frequency
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 up to 116 GHz.
