30mil Taconic CER-10 2-layer Immersion Silver DK10 High Frequency Laminate PCB

30mil Taconic CER-10 2-layer Immersion Silver DK10 High Frequency Laminate PCB

1.Product Overview

This 30mil CER-10 2-layer PCB represents a sophisticated integration of Taconic's proprietary organic-ceramic laminate technology with precision fabrication processes. Designed for high-frequency microwave applications, this 30mil Taconic board combines the electrical advantages of a high-Dk ceramic-filled PTFE composite with the mechanical robustness of woven glass reinforcement. The resulting product delivers consistent RF performance, excellent dimensional stability, and long-term reliability in challenging operating environments.

The selection of TaconicC ER-10 as the base material is particularly significant for applications requiring stable dielectric properties over frequency and temperature. With a nominal dielectric constant of 10.0 at 10 GHz and a dissipation factor of 0.0035, this material minimizes signal loss while enabling circuit miniaturization–a critical advantage for modern compact microwave assemblies.

5.Core Differentiated Performance Advantages of This CER-10 Immersion Silver PCB

5.1 High-Frequency Electrical Stability (Core Differentiator vs Common RF PCBs)

The substrate’s fixed Dk=10 at 10 GHz and ultra-low Df=0.0035 eliminates frequency drift of dielectric constant, a critical advantage over FR-4 (Df>0.02) and general low-Dk PTFE laminates. The bare copper + immersion silver finish removes dielectric solder mask covering transmission lines, cutting insertion loss by 12–18% at microwave bands compared to masked RF boards. Immersion silver delivers a flat, non-porous pad surface with uniform thin silver coating, perfectly matching the skin effect of high-frequency microwave current and avoiding uneven signal attenuation caused by HASL’s uneven tin-lead surface.

5.2 Mechanical & Thermal Reliability for Compact Miniaturization

CER-10’s woven glass reinforcement delivers stable X-Y axis CTE (13–15 ppm/°C) and low Z-axis thermal expansion of only 46 ppm/°C, drastically reducing PTH barrel cracking risk during thermal cycling of power amplifiers and filters. Interlaminar bond strength outperforms standard ceramic-filled PTFE materials, resisting delamination under multiple reflow soldering cycles; moisture absorption is limited to 0.02%, so dielectric performance remains consistent in high-humidity industrial environments without capacitance shift or signal phase deviation. With UL94 V-0 flame retardancy, the PCB meets safety requirements for high-power RF amplifier hardware.

5.3 Manufacturing & Application Customization Value

The 5/6 mil fine line processing capability supports miniaturized microwave passive component layout, while the 0.4mm minimum drill size balances high-density routing and mechanical hole wall integrity. The 2-layer simple rigid stackup cuts fabrication cost and lead time versus multi-layer hybrid high-frequency boards, and the 100% electrical test rule eliminates open/short circuit defects before delivery. Standard PTFE machining processes (shearing, drilling, plating) apply to CER-10, so manufacturers can process this PCB without specialized custom equipment. Primary target applications include power amplifiers, waveguide filters, directional couplers and compact microwave passive components across telecommunication RF frontends and radar sensor systems.
