2-Layer RF-30A High-Frequency PCB – 20mil (0.6mm) with ENIG Finish
Product Introduction
We present our 2-Layer RF-30A PCB – a high-performance, thin-profile circuit board engineered for demanding RF and microwave applications. Fabricated with RF-30A laminate (Dk 3.0, Df 0.003 @ 10 GHz) and finished with Electroless Nickel Immersion Gold (ENIG) , this 0.6mm (20mil) board delivers excellent signal integrity, low insertion loss, and superior environmental stability. The thin dielectric profile minimizes parasitic effects, making it ideal for compact, high-frequency wireless and radar systems.

Why RF-30A?
RF-30A is a next-generation RF laminate featuring an advanced resin system and optimized glass fabric reinforcement. Unlike conventional PTFE-based materials, RF-30A processes like standard FR4 – no special handling required – while delivering exceptional high-frequency performance. With a Tg >180°C, it fully supports 260°C lead-free assembly and offers outstanding thermal and chemical resistance for harsh operating environments.

Benefits of This 20mil RF-30A PCB
Ultra-Low Loss: Df of 0.003 at 10 GHz minimizes signal attenuation for long RF traces.
Stable Dk: Consistent dielectric constant across frequency and temperature ensures predictable impedance control.
Thin Profile (20mil): Reduces parasitic capacitance and inductance, ideal for compact RF modules and portable devices.
Lead-Free Assembly Ready: Withstands 260°C reflow (T260 >90 min, T288 >30 min).
CTE Matched to Copper: X/Y CTE (9–13 ppm/°C) closely matches copper, reducing stress on plated vias and improving solder joint reliability.
ENIG Finish: Provides a flat, solderable, oxidation-resistant surface for fine-pitch SMT components (24 top SMT pads).
Process-Friendly: No PTFE-specific handling – compatible with standard FR4 fabrication lines, reducing lead times and cost.
Reliable in Harsh Environments: Ultra-low moisture absorption (0.08%) and excellent CAF/chemical resistance ensure long-term field performance.
