We are a profesional FR4 PCB Circuit Board manufacturer in China, and we can offer a various of single sided to multilayer PCB to you.
F (for flame) and R (for retardancies) and the 4 is a 4 epoxy.FR4 is a glass fiber epoxy laminate.FR4 is the Main material for PCB manufacture, it is the excellent quality and reasonable price material
FR-4 is widely used for single and multilayer boards, which has excellent thermal tolerance as much as 130°C. Now this type material FR-4 is more widely manufactured, but the hence is less costly.
