RO4350B™ Laminates

Rogers RO4350B materials are proprietary woven glass reinforced hydrocarbon/ceramics with electrical performance close to PTFE/woven glass and the manufacturability of epoxy/glass.

RO4350B laminates provide tight control on dielectric constant (Dk) and maintain low loss while utilizing the same processing method as standard epoxy/glass. Available at a fraction of the cost of conventional microwave laminates, RO4350B laminates do not require the special through-hole treatments or handling procedures as PTFE based materials. These materials are UL 94 V-0 rated for active devices and high power RF designs.


  • Dk of 3.48 +/- 0.05
  • Dissipation factor of 0.0037 @ 10 GHz
  • Low Z-axis coefficient of thermal expansion @ 32 ppm/°C


  • Processes like FR-4 at lower fabrication cost
  • Competitively priced
  • Excellent dimensional stability
