Why Hybrid Stack-ups?
Pure Rogers boards can cost 3-5x more than FR4. A hybrid stack-up (Rogers outer layers + FR4 core) provides 80% of the performance at 40% of the cost.

Why Engineers Switch to Us
“PCBLion’s engineering team suggested a hybrid Rogers/FR4 stack-up and caught a critical impedance mismatch in our antenna feedline during DFM. They saved us a costly re-spin and improved our signal range.”

Frequently Asked Questions
Do you stock high-frequency materials to support quick-turn prototypes?
Yes. We maintain a bonded inventory of premium high-frequency laminates, including Rogers, Taconic, and Isola. This allows us to start production immediately and deliver RF prototypes in as fast as 5-7 working days.
How do you ensure via reliability and signal integrity for PTFE-based microwave boards?
PTFE (Teflon) materials are inherently non-stick and notoriously difficult to plate. We utilize a rigorous Plasma Desmear process before plating to alter the hole-wall chemistry, ensuring robust copper adhesion and eliminating via failures during thermal cycling. Furthermore, we maintain ultra-tight trace etching tolerances down to ±0.0005″ (12.7µm) to mitigate “skin effect” losses and maintain strict ±5% impedance.
Can I combine standard FR4 with high-frequency materials to save cost?
Yes, this is a highly recommended practice known as a Hybrid Stack-up. We frequently laminate expensive RF materials (like Rogers or Taconic) on the critical outer signal layers, while using standard High-Tg FR4 for internal power and ground routing. This maintains excellent signal integrity while significantly reducing your overall board cost.
