Material Composition: Rogers TMM4 is a ceramic, hydrocarbon, thermoset polymer composite tailored

for high plated-through-hole reliability in stripline and microstrip applications, with a dielectric constant

of 4.70.

Benefits: TMM4 amalgamates the advantages of ceramic and traditional PTFE microwave circuit materials,

without necessitating specialized production techniques. Unlike some materials, it does not need a sodium

napthanate treatment before electroless plating.

Thermal Properties: TMM4 boasts an impressively low thermal coefficient of dielectric constant, typically

below 30 PPM/°C. Its isotropic coefficient of thermal expansion closely mirrors that of copper, enabling

the creation of dependable plated through-holes and minimal etch shrinkage.

Thermal Conductivity: The material offers a thermal conductivity roughly double that of conventional PTFE

/ceramic materials, aiding in effective heat dissipation.

Thermoset Resins: TMM4, being based on thermoset resins, retains its structural integrity when exposed to

heat. Consequently, wire bonding of component leads to circuit traces can be conducted without worrying

about pad lifting or substrate deformation.
