Key Characteristics of High-Frequency Substrate Materials
- The dielectric constant (Dk) must be small and stable for optimal signal transmission
- Dielectric loss (Df) must be minimal to ensure high signal quality
- Copper foil thermal expansion coefficient should match the substrate material
- Low water absorption to maintain stable dielectric properties
- Excellent heat resistance, chemical resistance, impact strength, and peel strength
High-frequency applications typically operate above 1GHz. Current high-frequency PCB substrates include fluoropolymer-based materials (PTFE) for frequencies above 5GHz, and FR-4 or PPO substrates for 1GHz-10GHz applications.
The three primary high-frequency substrate materials are epoxy resin (most economical), PPO resin, and fluoropolymer resin (highest performance). Fluoropolymer substrates offer superior dielectric properties but require special copper foil treatment due to their molecular inertness.
Advanced fluoropolymer PCB development requires collaboration between material suppliers, research institutions, equipment manufacturers, and PCB producers to meet the evolving demands of high-frequency circuit applications.
