RT/duroid 6035HTC 2-Layer 60mil ENIG PCB for High Power RF Applications

1. Introduction

Rogers RT/duroid 6035HTC high frequency circuit materials are ceramic filled PTFE composites for use in high power RF and microwave applications. They are an exceptional choice for high power applications. The laminates have a thermal conductivity of almost 2.4 times the standard RT/duroid 6000 products, and copper foil (ED and reverse treat) with excellent long term thermal stability. Additionally, Rogers advanced filler system enables excellent drill-ability, reducing drilling costs as compared to standard high thermally conductive laminates that use alumina fillers.
