TMM® Thermoset Microwave Materials

TMM® thermoset microwave materials are ceramic, hydrocarbon, thermoset
polymer composites designed for high plated-thru-hole reliability stripline
and microstrip applications. TMM laminates are available in a wide range of
dielectric constants and claddings.
The electrical and mechanical properties of TMM laminates combine many of
the benefits of both ceramic and traditional PTFE microwave circuit laminates,
without requiring the specialized production techniques common to these
materials. TMM laminates do not require a sodium napthanate treatment prior
to electroless plating.

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

TMM laminates are 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.

TMM laminates combine many of the desirable features of ceramic substrates
with the ease of soft substrate processing techniques. TMM laminates are
available clad with 1/2 oz/ft2
to 2 oz/ ft2 electrodeposited copper foil, or bonded
directly to brass or aluminum plates. Substrate thicknesses of 0.015” to 0.500” are
available. The base substrate is resistant to etchants and solvents used in printed
circuit production. Consequently, all common PWB processes can be used to
produce TMM thermoset microwave materials.
