FR4 PCB Material

FR4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing). Because of this FR4 is the most common substrate used in Printed Circuit Board (PCB) manufacture.

With near zero water absorption, FR4 is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. 

Below are a few FR4 manufactures along with their datasheets. If you require a substrate not listed then please get in contact with us as we have most likely manufactured PCB’s using it anyway.
