Ohmite's thermal interface materials (TIMs) are designed for use in applications requiring reliable performance, low contact resistance, long life, low maintenance, and high thermal conductivity. The flexible graphite materials are die-cut to ensure an exact fit and reduce module-to-module variation during assembly. The compressibility of the material improves surface contact and reduces thermal impedance. The material compression can compensate for flatness variations of up to 125 μm. The high in-plane thermal conductivity of this material reduces hot spots.
Ohmite’s high-performance TIMs are designed for long life applications with extreme heat cycles and are made of flexible graphite specifically engineered for demanding power electronics applications.
