Introducing our latest shipment of PCBs based on TMM3: the ultimate solution for high-reliability strip-line and micro-strip applications. The Rogers TMM3 thermoset microwave material combines the best features of ceramic and traditional PTFE microwave circuit laminates, all without the need for specialized production techniques. With TMM3 laminates, you can enjoy the benefits of exceptional performance and reliability while avoiding pad lifting or substrate deformation during wire-bonding.
The TMM3 substrates offer exceptional performance and reliability. With a dielectric constant (Dk) of 3.27 +/- .032 at 10GHz and a dissipation factor as low as .0020 at 10GHz, these PCBs ensure consistent signal performance and excellent signal integrity. They also feature a thermal coefficient of Dk of 37 ppm/°K for stability across temperature variations and a high decomposition temperature (Td) of 425°C TGA for thermal stability. Additionally, the PCBs have a copper-matched coefficient of thermal expansion and a thermal conductivity of 0.7W/mk for enhanced reliability and efficient heat dissipation. Available in a thickness range of .0015 to .500 inches (+/- .0015”), these PCBs provide versatility to meet various design requirements.
