EMI shielding and thermal management: our two areas of expertise
Electromagnetic compatibility (EMC): EMI/RFI shielding and protection
A device that emits interference, or picks it up from the equipment around it, fails its EMC tests or behaves erratically in the field. The leak seldom comes from the metal walls of the enclosure. It comes through the openings: a door, a removable panel, the seam between two covers. That is where our EMI/RFI shielding products go.
Fabric-over-foam gaskets, a soft foam core wrapped in conductive fabric, suit lightweight enclosures because they need very little force to compress. Conductive silicone gaskets, filled with nickel-graphite or silver particles, shield and seal against water and dust at the same time. Contact fingers in beryllium copper or stainless steel keep electrical contact on doors and panels that are opened every day. Knitted wire mesh gaskets in Monel or stainless steel come in round or rectangular sections, with or without a silicone core. Depending on the material and the frequency, shielding effectiveness ranges from 40 dB to more than 100 dB.
Thermal management and thermal interface materials
Heat is the other threat to electronics: a component that runs too hot ages faster and loses performance. Between that component and its heat sink there is usually a small, uneven gap filled with air, and air conducts heat poorly. Our silicone thermal pads fill that gap.
They range from 0.3 to 15 mm thick and from 3 to 5 W/m·K, and they are soft enough to follow the surfaces without putting stress on the board. These soft thermal interface materials also provide electrical insulation (4 to 5 kV/mm dielectric strength, depending on the version) and are rated UL 94 V-0. Alongside our EMC/EMI shielding range, you will find them in automotive, medical, aerospace, telecoms and industrial equipment.
