Rogers TMM13i Substrate Introduction

Rogers TMM13i is a ceramic-filled hydrocarbon thermoset polymer composite microwave laminate, specifically designed for high-reliability plated thru-hole (PTH) stripline and microstrip applications.

It features an isotropic dielectric constant (Dk) with a thermal coefficient of dielectric constant of less than 30 ppm/°C, ensuring excellent electrical stability across a wide temperature range. The material exhibits isotropic coefficient of thermal expansion (CTE) that closely matches that of copper, significantly enhancing plated thru-hole reliability under thermal cycling. Low etch shrinkage enables high-precision circuit patterning. Its thermal conductivity is approximately twice that of conventional PTFE/ceramic laminates, providing superior heat dissipation.

Based on a thermoset resin system, TMM13i does not soften when heated, eliminating concerns of pad lifting or substrate deformation during wire bonding. Furthermore, it requires no sodium naphthalate pretreatment prior to electroless plating and can be processed using standard PCB fabrication equipment, combining excellent RF performance with manufacturing convenience.
