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.

Features:

The RO4350B laminates boast remarkable features that make them an ideal choice for high-frequency applications. With a dielectric constant (DK) of 3.48 ± 0.05 at 10GHz and a dissipation factor of 0.0037 at the same frequency, these laminates deliver excellent electrical performance. Additionally, the thermal conductivity of 0.69 W/m/°K ensures efficient heat dissipation. Their coefficient of thermal expansion (CTE) values are 10ppm/°C in the X-axis, 12ppm/°C in the Y-axis, and 32ppm/°C in the Z-axis, providing stability across temperature variations. Operating within a wide temperature range of -40℃ to +85℃, the RO4350B laminates exhibit exceptional thermal resilience.
