TRF-45 PCB: 2-Layer 32mil Thick ENIG Finished High-Frequency Circuit Board

1.Introduction

The TRF-45 laminated materials represent a new generation of low-loss, thermally-stable laminated material from Taconic Advanced Dielectric Division. TRF-45 is woven-glass reinforced for enhanced dimensional stability and coupled with Taconic's expertise in ceramic technology. It exhibits low and consistent Z-axis expansion across a wide range of temperatures, including soldering conditions.

TRF-45 can be sheared, drilled, and plated using standard methods for PTFE woven fiber-glass materials, making it ideal for high-frequency applications.
