What circuit boards do we do? (35) TMM 10i High Frequency PCB

Introduction

Rogers’ TMM10i microwave material is a ceramic thermoset polymer composite designed for high plated thru-hole reliability strip-line and micro-strip applications. This cutting-edge material combines the best qualities of ceramic and PTFE substrates while incorporating soft substrate processing techniques for effortless fabrication.

TMM10i laminates possess isotropic dielectric constant and coefficients of thermal expansion. The CTE closely aligns with copper that enables the creation of highly reliable plated through holes and minimizing etch shrinkage. Additionally, the thermal conductivity of TMM10i laminates is approximately double that of conventional PTFE/ceramic laminates, thus enhancing heat dissipation capabilities.

Features & Benefits

With a Dk of 9.80 +/- .245, TMM 10i increases the capacitance of capacitors, allowing for smaller designs while maintaining performance. This is beneficial in high-frequency applications where size and efficiency are critical.

Its impressively low dissipation factor of .0020 at 10GHz guarantees minimal signal loss, distortion and attenuation.

Moreover, its thermal coefficient of Dk at -43 ppm/°K and copper-compatible coefficient of thermal expansion contribute to excellent thermal stability.

The mechanical properties of TMM 10i make it highly resistant to creep and cold flow, ensuring long-term reliability in demanding environments.

Additionally, its resistance to process chemicals minimizes damage during fabrication, streamlining production processes.
