Thermal SIL PAD® Materials

Bergquist Company Thermal SIL PAD® Materials are electrically and non-electrically insulating silicone thermal interface materials. These materials minimize thermal resistance from the external package of a power semiconductor to the heat sink. This is achieved by isolating the semiconductor electrically from the heat sink and providing sufficient dielectric strength to withstand high voltage. The Bergquist SIL PAD materials are made of conformable fiberglass and silicone rubber, which provides a more versatile material than mica or ceramics and grease. These materials are designed to be clean, grease-free, and flexible. The SIL PAD materials feature reinforcements to resist cut-through, a wide range of thermal conductivities and dielectric strengths, and excellent thermal performance with minimized thermal resistance. These cost-effective materials are resistant to electrical shorting and enhance performance for high-heat compacted assemblies.
