IsoClad 933 PCB 2-Layer 31mil High-Frequency PTFE Laminates for Conformal Antennas and Radar Systems

1. Introduction of IsoClad 933

Rogers IsoClad 933 laminates are non-woven fiberglass/PTFE composites designed for use as PCB substrates. The non-woven reinforcement makes these laminates suitable for applications where the final circuit requires conformability. IsoClad 933 laminates utilize longer random fibers and a proprietary manufacturing process to achieve excellent dimensional stability and enhanced mechanical strength.

2.Features

Dielectric Constant (DK) of 2.33 at 10 GHz/23°C
Dissipation Factor of 0.0016 at 10 GHz/23°C
Strong Peel Strength of 10 lbs per inch
Low water absorption at 0.05%
Low outgassing with 0.03% TML, 0 CVCM, and 0.02% WVR
