FR4 material consists of a thin layer of copper foil laminated to one or both sides. By contrast, multi-layer PCBs consist of multiple layers of PCB material which are laminated together.

At Bay Area Circuits, to offer many different types of PCB materials for PCB manufacture, from standard FR4 material to Flex, High Copper Weight, Hybrid Capable, Low/High Temp and Polyimide materials, we work with a variety of material suppliers including Arlon, Isola, Iteq, Nelco, Rogers, Taconic, Tuc & Ventec.

Our Material Library provides links to data sheets for many of the more popular PCB materials we offer; RF, Polyimide and FR4 material.  This is by no means an all-inclusive list of materials we offer so please contact us for information on other available material suppliers and types.

Your application should influence your choice of PCB material (e.g. printed circuit board assemblies). If you need assistance selecting the right material – whether it’s standard FR4 material or something unique – contact our customer service team and we’ll be glad to assist!
