Double-Sided 10mil RF PCB


RF High Frequency PCB Board

We're excited to share our newly shipped RF PCB here with you.It's a high frequency PCB made of RO4350B laminates. Rogers RO4350B, a cutting-edge solution that combines the electrical performance of PTFE/woven glass with the ease of manufacturability found in epoxy/glass materials. Developed by Rogers Corporation, the RO4350B laminates offer exceptional control over dielectric constant (Dk) while maintaining low loss characteristics. These advanced materials provide a cost-effective alternative to conventional microwave laminates, eliminating the need for special through-hole treatments and handling procedures typically associated with PTFE-based materials. Notably, the RO4350B laminates are UL 94 V-0 rated, making them suitable for active devices and high power RF designs.
