TMM6 2-Layer 15mil PCB – High-Frequency RF Microwave Circuit Board with Immersion Silver Finish
1.Introduction to TMM6 2-Layer 15mil PCB
Rogers TMM6 is a ceramic thermoset microwave laminate designed for high plated through-hole reliability in stripline and microstrip applications. Combining the benefits of ceramic and traditional PTFE materials, TMM6 does not require specialized production techniques and offers a unique dielectric constant within its product family. This makes it an ideal choice for high-frequency and high-reliability PCB designs.
