CEM-3 PCB Manufacturer
CEM-3 PCB Manufacturer in India
If your application requires a balance between performance and cost, choosing a reliable CEM-3 PCB manufacturer is crucial. At RAPID CIRCUIT, we manufacture highquality CEM-3 PCBs that offer improved electrical and mechanical performance compared to CEM-1 and FR1, making them ideal for OEMs and industrial applications. Â
What is a CEM-3 PCB?
A CEM-3 PCB is made from a composite glass epoxy material similar to FR4 but with a different internal structure. It typically consists of woven glass fabric layers combined with epoxy resin, providing better strength and electrical performance than paper-based materials.
CEM-3 is often used as a cost-effective alternative to FR4 in double-sided PCB applications.
