(PCB's are custom-made products, the picture and parameters shown are just for reference)

Rogers TMM4 thermoset microwave material is ceramic, hydrocarbon, thermoset polymer composite designed for high plated-through-hole reliability stripline and microstrip applications. It's available with dielectric constant at 4.70. The electrical and mechanical properties of TMM4 combine many of the benefits of both ceramic and traditional PTFE microwave circuit materials, without requiring the specialized production techniques. It does not require a sodium napthanate treatment prior to electroless plating.

TMM4 has an exceptionally low thermal coefficient of dielectric constant, typically less than 30 PPM/°C. The material’s isotropic coefficient of thermal expansion, very closely matched to copper, allows for production of high reliability plated through holes, and low etch shrinkage values. Furthermore, the thermal conductivity of TMM4 is approximately twice that of traditional PTFE/ceramic materials, facilitating heat removal.

TMM4 is based on thermoset resins, and do not soften when heated. As a result, wire bonding of component leads to circuit traces can be performed without concerns of pad lifting or substrate deformation.
