Rogers DiClad 527 PCB: Stable Dk and Low Loss 0.0018 for Radar and Base Station Antennas

Printed Circuit Boards are custom-made products; the images and specifications provided are for reference only.

General Description

Rogers DiClad 527 PCBs are fiberglass-woven reinforced composite materials, specifically engineered to serve as substrates for printed circuit boards.

Compared to pure PTFE-based materials, DiClad 527 laminates feature a higher proportion of fiberglass reinforcement relative to PTFE content. This precisely balanced composition not only enables a broader range of adjustable dielectric constant (Dk) values but also enhances two critical performance attributes: superior dimensional stability and more accurate registration during PCB manufacturing.
