PTFE Composite Material High Frequency PCB Board DiClad 527

Substrate Introduction

Rogers DiClad 527 laminates are composite materials reinforced with woven fiberglass for use as substrates in printed circuit boards. These laminates offer a higher proportion of fiberglass reinforcement compared to PTFE content. This carefully balanced ratio results in a wider range of dielectric constant (Dk) and improved dimensional stability and registration.
