Rogers IsoClad 933 PCB 2-layer 20mil 0.508mm Substrate ENIG

Rogers IsoClad 933 PCB 2-layer 20mil 0.508mm Substrate ENIG

Introduction

The 20mil IsoClad 933 PCB is a high-performance 2-layer rigid printed circuit board designed for RF, microwave, and aerospace applications where flexibility, low signal loss, and dimensional stability are critical. Built on IsoClad 933—a nonwoven fiberglass/PTFE composite—thisIsoClad laminates PCB offers superior dielectric uniformity, bend tolerance, and thermal stability, making it ideal for conformal antennas, missile guidance systems, and radar electronics.

With an ultra-low dielectric constant (Dk) of 2.33 @ 10GHz and an exceptional dissipation factor (Df) of 0.0016, this Rogers IsoClad PCB ensures minimal signal attenuation in high-frequency circuits. Its nonwoven fiberglass reinforcement provides greater flexibility than traditional woven fiberglass PCBs, allowing it to conform to curved surfaces without delamination.
