The Taconic RF-35 6-Layer Hybrid PCB is a high-performance circuit board engineered to handle high-frequency microwave signals while maintaining a cost-effective, rigid structure. By combining advanced Taconic RF-35 PTFE-based materials with standard FR4 cores, this hybrid stackup allows designers to route sensitive, low-loss RF signals on the outer layers while utilising the internal FR4 layers for lower-frequency control circuits and power distribution. This precise material integration minimises signal attenuation, reduces thermal expansion mismatch, and significantly optimises overall production costs for complex multi-layer assemblies.
Key Features of the Taconic RF-35 Hybrid Stackup
-
Advanced Material Integration: Combines woven fiberglass matrix PTFE-based Taconic RF-35 laminates with reliable FR4 glass epoxy.
-
Optimised Dielectric Properties: Features a stable dielectric constant ($D_k$) of $3.50 \pm 0.1$ at 1.9 GHz for predictable impedance control.
-
Low Dissipation Factor: Achieves a low loss tangent ($D_f$) of 0.0018 at 1.9 GHz, drastically reducing signal insertion loss.
-
6-Layer Build Configuration: Engineered with a balance of dedicated RF signal routing outer planes and internal power/ground distribution layers.
-
Thermal and Mechanical Reliability: Low moisture absorption (less than 0.02%) ensures dimensional stability across fluctuating operating environments.
-
Surface Finish Options: Available with ENIG (Electroless Nickel Immersion Gold) or HASL-LF to support ultra-fine pitch component placement and reliable solder joints.
Applications
-
Wireless Communications: Cellular base station antennas, power amplifiers, and satellite receiver modules.
-
Radar and Navigation: Automotive radar collision avoidance systems and marine navigation control boards.
-
High-Speed Computing: Enterprise servers, backplanes, and high-frequency data routing switches.
-
Industrial Telemetry: Remote monitoring hardware and high-speed test instrumentation.
