Overview of TMM10
Rogers’ TMM10 thermoset microwave materials are ceramic, hydrocarbon, thermoset polymer composites designed for high reliability in plated-thru-hole stripline and microstrip applications. These laminates combine the benefits of both ceramic and traditional PTFE microwave circuit laminates without necessitating specialized production techniques common to these materials.
TMM10 laminates feature an exceptionally low thermal coefficient of dielectric constant, typically less than 30 ppm/°C. Their isotropic coefficients of thermal expansion are closely matched to copper, which facilitates the production of high-reliability plated-through holes and minimizes etch shrinkage values. Additionally, the thermal conductivity of TMM10 laminates is approximately twice that of traditional PTFE/ceramic laminates, enhancing heat removal capabilities.
TMM10 laminates are based on thermoset resins, meaning they do not soften when heated. This property enables wire bonding of component leads to circuit traces without concerns about pad lifting or substrate deformation.
