Conductive Shielding and Thermal Gap Pads

Die Cut EMI/RFI Shielding Gaskets 

Electromagnetic interference (EMI) can disrupt the operations or affect the performance of electronic systems, equipment, and individual devices. For ones used in critical applications, such as in the aerospace, medical, military, navigation, or transit sectors, these disruptions or alterations can have catastrophic effects.

EMI/RFI shielding gaskets serve as a preventative measure, protecting sensitive electronics from both electromagnetic and RFI (radio-frequency interference). These hybrid mechanical-electrical devices are made of various conductive elastomers and filled silicones suitable for use in a variety of operating environments and temperature extremes. Depending on the project specifications and application, the gaskets can be designed using a pressure-sensitive adhesive (PSA), mechanical fastening, or grooved press-fitting methods.

Die Cutting for Thermal Transfer Pads

We manufacture thermal conductive gap filler pads for managing heat within electronic assemblies. These gap fillers are used to bridge the interface between hot components and a chassis or heat sink assembly to increase the overall heat transfer from the system. The unique combination of thermal conductivity and softness reduces mechanical stress while maintaining thermal performance. We are authorized distributors of extensive gap filler product lines that cover a wide range of performance capabilities, including ultra-thin gap fillers, a high deflection, and materials that provide electrical isolation.

Thermal gap filler pads are made from silicone polymer that is combined with a thermal medium (usually ceramic). The silicone and ceramic powders are mixed, cast, and cured to a soft, conformal thermal pad in sheet form. Gap filler pads are inherently tacky which also aids in the assembly process. Thermal pads are also more stable than phase change products and have higher operating temperatures. Thermal conductivity silicone gap filler pads range in thickness from .020″ to .250″. Thermal performance ranges from 1.0 Watt/meter-Kelvin (W/m-K) to 5.0 W/m-K. Gap pads are cut into individual pads using our digital cutting process or die-cut for larger quantities.
