About RO4350B

RO4350B laminates offer tightly controlled dielectric constants (Dk) and low loss characteristics, and can be processed using the same methods as standard epoxy/glass. Unlike PTFE, RO4350B laminates do not require specialized through-hole processing or handling procedures, resulting in significantly lower processing costs than traditional microwave laminates. The material also achieves a UL 94 V-0 flame retardancy rating, making it suitable for active device and high-power RF designs.

Advantages

• Low RF loss

• Minimal dielectric constant fluctuation with temperature

• Low z-axis thermal expansion coefficient
  

• Low board expansion coefficient
  
• Low dielectric constant tolerance
  
• Stable electrical characteristics at different frequencies
  
• Easy to mass produce and multi-layer mixing, high cost-effectiveness
