The Rogers IsoClad 933 is a high-performance printed circuit board (PCB) substrate material that offers excellent electrical and mechanical properties. Manufactured by Rogers Corporation, a leading provider of advanced circuit materials, the IsoClad 933 is a non-woven fiberglass/PTFE composite designed for use in a wide range of applications, from conformal antennas to high-frequency radar systems.

Material Composition and Key Features:
The IsoClad 933 is a unique PCB substrate material that utilizes a proprietary manufacturing process to create a non-woven fiberglass reinforcement. This construction allows the material to be more flexible and conformable compared to traditional woven fiberglass laminates, making it suitable for applications where the final circuit may need to be shaped or bent.

The key features of the IsoClad 933 include:

Dielectric Constant (Dk) of 2.33 at 10 GHz and 23°C
Dissipation Factor (Df) of 0.0016 at 10 GHz and 23°C
Exceptional Peel Strength of 10 lbs per inch
Low Water Absorption of 0.05%
Extremely Low Outgassing with 0.03% TML, 0 CVCM, and 0.02% WVR
Highly Uniform Dielectric Constant across the Material
 

These characteristics make the IsoClad 933 an ideal choice for high-frequency, high-performance circuit designs, where consistent electrical properties and dimensional stability are crucial.
