Definition

Taconic RF-35 uses ORCER (organic ceramic) construction combining ceramic filling with PTFE-coated fiberglass for FR-4-like processing with RF performance. Dk 3.50 ±0.10, Df 0.0019-0.0025, Tg >315°C. The key advantage: RF-35 processes with standard epoxy/glass methods, avoiding sodium naphthalene treatment and special drilling procedures. It's the best choice for low-cost, high-volume commercial microwave production. RF-35TC variant achieves Df 0.0011 with enhanced thermal conductivity and won't oxidize or yellow like some hydrocarbon competitors. Use RF-35 for commercial GPS, WiFi, and cellular applications where RO4350B performance is needed but volume pricing matters.
