Rogers RO4350B PCB Double-Layer Circuit Board

Introduction to RO4350B

Rogers RO4350B materials represent a significant advancement in PCB technology, combining the best aspects of woven glass-reinforced hydrocarbon/ceramics with electrical performance characteristics that closely mimic those of PTFE/woven glass laminates. This innovative material provides the manufacturability of traditional epoxy/glass while maintaining tight control over the dielectric constant (Dk) and ensuring low loss.

RO4350B laminates offer a cost-effective alternative to conventional microwave laminates, eliminating the need for special through-hole treatments or handling procedures commonly associated with PTFE-based materials. Additionally, these laminates have achieved a UL 94 V-0 rating, making them suitable for active devices and high-power RF designs. The thermal coefficient of expansion (CTE) of RO4350B closely matches that of copper, providing excellent dimensional stability essential for mixed dielectric multi-layer board constructions.
