What Makes CER-10 High Frequency PCB the Ideal Choice for Demanding RF Applications?

In the rapidly advancing world of wireless communication, radar systems, and aerospace technology, the demand for high-frequency printed circuit boards (PCBs) that deliver uncompromising performance and unwavering reliability is greater than ever. Selecting the right substrate material is a foundational decision that directly impacts the efficiency, signal integrity, and longevity of your electronic designs. Among the top-tier materials available,Taconic CER-10 High Frequency PCB laminate emerges as a premier solution. But what specific attributes position CER-10 PCB as the ideal choice for the most demanding RF and microwave applications? This article explores the advanced material properties, robust manufacturing capabilities, and critical application strengths that define the CER-10 advantage.

Superior Material Properties for Peak High-Frequency Performance

Taconic CER-10 belongs to Taconic's esteemedORCER product family, which represents a sophisticated fusion of organic compounds and ceramic elements. This unique organic-ceramic composition is engineered to excel where standard FR-4 materials fall short.

1) Exceptional Dielectric Properties: At the heart of its performance is a stable dielectric constant (Dk) of 10 and an exceptionally low dissipation factor (Df) of just 0.0035 at 10 GHz. This combination is critical for high-frequency circuits, as it enables effective miniaturization (a higher Dk allows for smaller wavelengths) while minimizing signal loss and heat generation, thereby preserving signal strength and clarity.

2) Enhanced Mechanical and Thermal Reliability: CER-10 is reinforced with a woven glass fabric, a feature that grants it outstanding dimensional stability and improved flexural strength, preventing warping during fabrication and operation. A key reliability feature is its optimized Z-axis coefficient of thermal expansion (CTE) of 46 ppm/°C. This low and controlled expansion is vital for protecting plated through-holes (PTHs) from stress and cracking during extreme temperature cycling, a common challenge in harsh environments.

3) Resilience in Challenging Conditions: The laminate exhibits ultra-low moisture absorption of only 0.02%, ensuring that its electrical properties remain stable even in humid conditions. Furthermore, CER-10 demonstrates low outgassing characteristics, with a Total Mass Loss (TML) of 0.02%, Collected Volatile Condensable Materials (CVCM) of 0.01%, and Water Vapor Regain (WVR) of 0.01% as per ASTM E 595. This makes it suitable for vacuum and space-related applications where contamination from outgassing is a major concern. Its UL 94 V-0 flammability rating confirms its compliance with stringent safety standards.
