Why the RF-10 PCB is a Breakthrough in RF Circuit Design

In the fast-evolving world of high-frequency electronics, engineers constantly seek PCBs that deliver low signal loss, stable dielectric properties, and superior thermal performance—all while keeping costs competitive.

Today, I’m proud to introduce our newly shipped RF-10 PCB, a 2-layer, 60mil immersion tin-finished board engineered for RF and microwave applications. Whether you're designing patch antennas, satellite components, or radar systems, this PCB is optimized for high-frequency stability, minimal insertion loss, and excellent thermal management.

Let’s dive into what makes this PCB a game-changer for RF engineers.

Key Features & Technical Advantages

1. Premium RF-10 Material for High-Frequency Performance

Unlike standard FR-4, the RF-10 laminate is a ceramic-filled PTFE composite with woven fiberglass, offering:

• Dielectric Constant (Dk) of 10.2 ± 0.3 @ 10GHz → Enables circuit size reduction without sacrificing performance.
• Ultra-low Dissipation Factor (0.0025 @ 10GHz) → Minimizes signal loss in high-frequency applications.
• Thermal Conductivity (0.85 W/mK) → Better heat dissipation than traditional RF substrates.
• Low CTE (16-25 ppm/°C) → Reduces risk of warping under thermal stress.

2. Optimized for Signal Integrity & Manufacturing Precision

• 2-layer stack-up with 1oz (35µm) copper for controlled impedance.
• 4/6 mil trace/space and 0.4mm minimum hole size for fine-line RF circuits.
• Immersion tin surface finish → Excellent solderability and oxidation resistance.
• 100% electrical testing ensures reliability before shipment.

3. Robust Construction for Demanding Environments

• 1.6mm total thickness with 60mil RF-10 core for mechanical stability.
• V-0 flammability rating → Suitable for aerospace and defense applications.
• Low moisture absorption (0.08%) → Performs reliably in humid conditions.
