Rogers IsoClad 933 2-Layer 1.6mm Flexible RF PCB for Conformal Antenna Applications
Rogers IsoClad 933 2-Layer 1.6mm Flexible RF PCB for Conformal Antenna Applications
Printed Circuit Boards are custom-made products; the images and specifications provided are for reference only.
Rogers IsoClad 933 PCB utilizes nonwoven fiberglass/PTFE composite technology to create circuit boards specifically engineered for applications requiring mechanical flexibility. The unique nonwoven reinforcement structure enables these laminates to be easily bent and formed into final shapes, making them ideal for conformal and wrap-around antenna designs. Through proprietary manufacturing processes and longer random fibers, IsoClad 933 PCB delivers superior dimensional stability and exceptional dielectric constant uniformity compared to similar nonwoven PTFE laminates.
