TMM10i High Frequency PCB Ceramic Thermoset Microwave Circuit Board

August 26, 2025

Introduction to TMM10i High Frequency PCB

Rogers TMM10i is a ceramic thermoset polymer composite material engineered for high plated through-hole reliability in strip-line and micro-strip applications. It combines the advantages of ceramic and PTFE substrates with easy processing features. The material offers isotropic dielectric properties and thermal expansion coefficients closely matched to copper, ensuring excellent PTH reliability and minimal etch shrinkage. Its thermal conductivity is approximately twice that of standard PTFE/ceramic laminates, significantly improving heat dissipation.

Key Features of TMM10i PCB

Stable Dielectric Constant (Dk) of 9.80 ±0.245 for consistent performance
Low Dissipation Factor of 0.0020 at 10GHz for minimal signal loss
Excellent Thermal Stability with CTE matched to copper and low thermal Dk coefficient
High Resistance to Creep and Cold Flow for long-term reliability
Chemical Resistance for easier fabrication and processing
Superior Thermal Conductivity for enhanced heat management
