Rogers RO4350B RF Printed Circuit Board (RFPCB)

Rogers ro4350b high frequency circuit board

Ro4350b is a patented hydrocarbon resin system/glass cloth reinforced ceramic filler. Its electrical properties are very close to those of PTFE/woven glass cloth materials, and the processing performance is similar to epoxy/glass cloth materials.

ro4350b can use standard epoxy/glass cloth processing techniques while providing tightly controlled dielectric constants and losses at a fraction of the price of traditional microwave materials. No special through-hole pretreatment or handling procedures are required like PTFE-based microwave materials.

Ro4350b materials have passed UL 94V-0 fire protection rating for active devices and high voltage RF designs.
