What circuit boards do we do? (27) TMM13i High Frequency PCB

Introduction

The Rogers TMM13i isotropic thermoset microwave material is a ceramic thermoset polymer composite tailored for high reliability in plated thru-hole strip-line and micro-strip applications. It features an isotropic dielectric constant (Dk) and integrates the advantageous properties of both ceramic and PTFE substrates, while allowing for the convenience of soft substrate processing methods.

Features

TMM13i laminates have a low thermal coefficient of dielectric constant of -70 ppm/°C, which ensures consistent dielectric performance over a wide temperature range, making it ideal for applications with expected temperature fluctuations.

The material’s isotropic coefficients of thermal expansion of 19, 19 and 20ppm/°C on X, Y and Z direction, very closely matched to copper, allow for production of high reliability plated through holes, and low etch shrinkage values.

Furthermore, TMM13i features a high dielectric constant of 12.85±0.35, allowing for the miniaturization of components and facilitating the development of more compact electronic devices.

Its low dissipation factor of 0.0019 at 10 GHz further enhances efficiency by minimizing energy loss, making it ideal for microwave circuits.
