The Rogers TMM 6 is a thermoset microwave component that is composed of a thermoset ceramic polymer. Its design boosts its reliability in high plated THT (through-hole) assembly. It also makes this laminate an excellent choice for microstrip and stripline applications. But are these the only feature that makes the Rogers TMM 6 one of a kind? Is there more to this incredible laminate? And if so, is it worth your money?
About the Rogers TMM 6 laminate and why it is unique
The Rogers TMM 6 laminate provides an incredible combo of the various benefits that traditional PTFE and Ceramic microwave circuit laminate provide. It achieves this feat without utilizing special production techniques, you hence save on cost and get a great laminate to use on your PCB.
Rogers TMM 6 laminates do not need to be treated via sodium naphthenate before electroless plating. They are hence, eco-friendly.
Rogers TMM 6 laminates have an impeccable dielectric constant when you compare them with other laminates. They also have a thermal coefficient that is exceptionally low. With these two features, the laminate can function perfectly in varying environments.
Rogers TMM 6 laminates have a thermal expansion isotropic coefficient that almost matches that of copper. Due to this property, these laminates become an excellent choice for plated THT (through-hole) production.

Rogers TMM 6 laminates have a thermal conductivity that is almost double that of the traditional ceramic/PTFE laminates. Due to this thermal conductivity, this laminate can eject a lot of heat within a short period.
Rogers TMM 6 laminates don’t soften when you heat them. They hence make the process of wire bonding different component leads to circuit traces easier and more effective. That is because, when undertaking this task, the chances of substrate deformation and pad lifting are pretty slim. You hence spend little to no time redoing a task due to these flaws.
Rogers TMM 6 laminates have varying thicknesses that range between 0.015″ – 0.500″. Hence, you can choose the thickness that suits your PCB and enjoy a remarkable performance.
Lastly, the base substrate in this laminate is pretty resistant to solvents and etchants. Due to this feature, the Rogers TMM 6 helps make the production phase more productive.
