The Taconic hybrid PCB multilayer stackup integrates high-performance, low-loss materials with structural FR-4 layers to deliver superior thermal and electrical stability. By utilizing this mixed-dielectric configuration, RF engineers can place expensive, low-loss Taconic laminates exclusively where high-frequency signals require low dissipation factors, utilizing cost-effective materials for the remaining layers. This precise material integration allows product developers and procurement managers to balance strict signal integrity requirements with commercial project budgets.
Key Features of Taconic Hybrid PCB Stackups
-
Mixed-Dielectric Integration: Combines Taconic PTFE/ceramic laminates (such as TLX, TLY, or RF series) with standard high-$T_g$ FR-4 or polyimide cores.
-
Optimised Electrical Performance: Low dissipation factor ($\tan\delta$) and stable dielectric constant ($D_k$) across wide frequency bands up to 40 GHz+.
-
Thermal and Structural Reliability: Carefully matched Coefficient of Thermal Expansion (CTE) across X, Y, and Z axes to prevent delamination during reflow.
-
Blind and Buried Via Support: Engineered to accommodate complex laser-drilled microvias and sequential lamination processes.
-
Surface Finish Options: Available with ENIG, ENEPIG, Immersion Silver, or ISIG to ensure reliable solder joints and wire bonding.
-
Compliance Standards: Manufactured in accordance with IPC-A-600 Class 2 or Class 3, RoHS, and REACH directives.
High-Frequency Applications
-
Telecommunications: Base station antennas, power amplifiers, and 5G cellular infrastructure components.
-
Aerospace & Defence: Radar systems, satellite communications (SATCOM), and guidance electronics.
-
Automotive: Advanced Driver Assistance Systems (ADAS), 77 GHz radar modules, and vehicle-to-everything (V2X) transceivers.
-
High-Speed Computing: Server backplanes, high-speed routers, and test and measurement instrumentation.
