Common Materials for Rigid PCBs

Standard Substrates

FR-4 (Fiberglass Epoxy)

  • Features: Cost-effective, high mechanical strength, flame retardant (UL94 V-0)
  • Applications: Consumer electronics, industrial controls

FR-1/FR-2 (Paper Phenolic)

  • Features: Ultra-low cost but poor heat resistance
  • Applications: Low-end appliances, simple circuits

High-Frequency Materials

Rogers Series (RO4000, RO3000)

  • Features: Low dielectric loss (Df <0.004), stable Dk
  • Applications: 5G antennas, satellite communications

Taconic TLY/TLF Series

  • Features: Ultra-low loss (Df as low as 0.001)
  • Applications: High-frequency filters, aerospace

Our engineers will help select the optimal material
