Rogers TMM 10i is a microwave circuit laminate based on a ceramic-filled hydrocarbon thermoset composite. Rogers identifies this grade by its isotropic dielectric constant. It belongs to the TMM family used for electrically and mechanically stable microstrip and stripline circuits.
Use grade-specific dielectric data
The Rogers product page lists a typical process dielectric constant of 9.80 and a design value of 9.9 for TMM 10i. TMM 10 has different published values, so the two product names should remain distinct in drawings, purchasing records and simulation files.
A high dielectric constant can support compact RF structures, but a useful design comparison also considers conductor geometry, dielectric thickness and fabrication tolerances. Evaluate the final circuit response rather than selecting a substrate from a single material property.
Agree the manufacturing requirements
TMM 10i is a thermoset material, and Rogers states that it does not require sodium treatment before electroless plating. Consult the manufacturer’s TMM fabrication and handling documents for the proposed board construction. Discuss drilling, routing, plated holes and assembly conditions before releasing a production drawing.
For a review, provide the operating band, full stackup, copper specification and electrical acceptance criteria. Explore related options in the RF materials guide or submit manufacturing files through the PCB quote form.
