At a Glance
Material Options
The Right Substrate for Your Frequency
Three Rogers configurations and six PTFE materials — each selected for specific performance bands.
Pure Rogers
All layers on RO4350B. Dk 3.48, Df 0.0037 @ 10GHz. Maximum consistency across the full stackup. Up to 12 layers.
Rogers + FR-4 Hybrid
RF signal on Rogers, digital/power on FR-4. 40-60% cost savings vs pure. Available in single-sheet or double-sheet configurations.
PTFE Teflon
Six substrate options from Dk 2.20 to Dk 3.50. Ultra-low loss for mmWave. Available in 2 and 4 layer configurations. Specialized processing for PTFE bonding and plating adhesion.
Rogers RO4350B
Industry-Standard RF Laminate
Proven Performance to 40GHz
Our RF-qualified factory maintains Rogers material certification and verifies Dk batch-to-batch for consistent production impedance.Dielectric Performance
Dk 3.48 ±0.05, Df 0.0037 @ 10GHz. Stable to 40GHz+ with minimal frequency dispersion.
Three Configurations
Pure (2-12L), Single Hybrid with 1 Rogers sheet (4-12L), Double Hybrid with 2 Rogers sheets (6-12L).
Process Compatible
Rogers RO4350B processes on standard FR-4 equipment — no special PTFE handling needed. Shorter lead times and lower cost than traditional PTFE.
Hybrid Advantage
Put your RF critical layer on Rogers, route digital on low-cost FR-4. Get the performance where it matters without paying for it everywhere.
PTFE Substrates
Ultra-Low Loss for mmWave
Six PTFE Options
PTFE requires specialized plasma treatment, sodium etch for adhesion, and controlled lamination pressure. Our PTFE-certified factory handles this daily. Available in 2 and 4 layer configurations only.Dk 2.20 (F4BME220)
Lowest dielectric constant. For 60-77GHz automotive radar and V-band communications.
Dk 2.65 (F4BM-2)
Standard PTFE with excellent Df. Available copper-clad or unclad for bonding.
Dk 3.38-3.50 (WL-CT338 / S7136H)
Cost-optimized PTFE alternatives. S7136H at ¥0.069/cm² — lowest cost PTFE option.
Specialized (SJ9294)
Dk 2.94 with buried resistor capability. For integrated passive designs.

FAQ
RF PCB Questions
Rogers vs PTFE — which should I use?
Rogers RO4350B: for most applications up to 40GHz. Process-compatible with FR-4 equipment, lower cost, faster turnaround. PTFE: when you need Dk below 3.0 or operation above 40GHz.
Pure Rogers vs Hybrid?
Hybrid saves 40-60% if only one signal layer needs low-loss performance. Pure when every layer carries RF signals (e.g., stripline filters, coupled-line structures).
What impedance tolerance can you achieve?
±8% standard on all RF builds with TDR verification. Every RF order ships with an impedance test report.
