Electromagnetic
Laird products’ ability to mitigate disruptive waste energy is reflected in our Electromagnetic business. A range of technologies in this sector, borne of the material sciences, significantly lowers stray electromagnetic interference. Microwave absorbers and mm wave absorbers in various configurations reduce the negative effects of radiated energy. As an enclosure solution, fabric-over-foam gaskets are a popular choice for applications requiring low compression force but also needing high conductivity and shielding attenuation. Our form-in-place elastomers are compatible with plastic, metal, and plated substrates. Electrically conductive elastomers provide environmental sealing for added protection. More than 400 standard Laird fingerstock metal gaskets are available for grounding and shielding. Standard surface mount board level shields are available in both one- and two-piece designs. The Electromagnetic business incorporates.
Microwave Absorbers
Microwave absorber and mm wave absorber products are for free space to cavity resonance through near field applications. Included are low loss dielectric materials such as filled polymers. Also available are custom molded elastomeric and thermoplastic, reticulated foam, along with textile, liquids, and custom composite products. Microwave absorbing gap fillers lower noise and open a thermal path. Hybrid absorbers in interface configurations resolve compliance issues at minimum deflection force. Ruggedized specialty microwave and custom magnetic absorbers are idea for use in harsh conditions on land, sea air. Elastomers and films net good shielding from low to high frequencies and solve internal cavity resonance issues up to the mm range.
Enclosure Solutions
Fabric-over-Foam
Laird fabric-over-foam gaskets provide soft shielding for computer, telecommunications or other applications where high conductivity and shielding attenuation are critical. The line comes in a variety of shapes and thicknesses to suit any need. Fabric-over-foam is available in nickel/copper and tin/copper to deliver versatile galvanic compatibility.
Electrically Conductive Elastomers / Form-in-Place Elastomers
Laird electrically conductive elastomers block signal interference and are ideal in fluctuating weather conditions, operating temperatures, and differing levels of chemical exposure and corrosion. Excellent mechanical functionality and electromagnetic shielding solve issues involving unique circumstances. Resilient Laird form-in-place gaskets deliver protection for compartmentalized case or plastic enclosures and packaged electronic assemblies. They optimize waste energy blocking and performance in a variety of electronics including telecom antennas, automotive (cluster/infotainment, chassis shielding, radar, autonomous driving, and datacom (optical transceivers, high speed connectors.
Fingerstock Metal Gaskets
We specialize in designing miniature parts of thin strip metal in quantities ranging from thousands to millions of pieces and offering an extensive selection of enclosure shielding gaskets.
These contact strips are used for grounding and shielding in high-frequency equipment and for forming large diameter contact rings. A wide variety of Beryllium Copper contact strips – tape mounted, clip-on, edge mount, slot and track, rail mounted, metal connector - provides engineers and designers with flexibility in solving grounding and shielding problems. Various lengths, widths, thicknesses, contours, and hole locations are possible. A low compression force version is available for every standard product.
Standard Board Level Shields
Laird’s standard surface mount shields are available in both one-piece and two-piece designs. One-piece shields offer six sides of electromagnetic interference protection. Two-piece shields enable inspection or repair of shielded components such as chip packages without having to risk board damage by removing the entire shield or incur any tooling costs. This makes repair of the component under the shield quicker and easier and reduces board re-work. There are no tooling costs associated with either the single-piece or two-piece standard designs.
