Multilayer PCB - Gold plated PCB

Gold plated PCB

When electronic devices demand long-term stability, anti-corrosion performance, and low-loss signal transmission—whether in 5G base stations, medical diagnostic equipment, or aerospace modules—Gold plated PCB stands out as a core component, leveraging gold’s inherent inertness and high conductivity to eliminate connectivity risks in harsh or high-precision scenarios.

Core Advantages: Material & Craftsmanship That Deliver Reliability

Each Gold plated PCB is built to strict specifications to meet critical industry needs:

Base Material: Adopts FR-4 (Tg 130–170°C) for general-purpose use, with optional Rogers substrates for high-frequency applications; the base ensures thermal stability even in temperature-fluctuating environments (e.g., industrial workshops or aerospace cabins).

Gold Plating Craft: Features a dual-layer structure of nickel underlayer (3–6μm) + gold plating (99.9% purity)—choose ENIG (Electroless Nickel Immersion Gold, 0.05–0.1μm gold) for fine-pitch soldering (e.g., BGA chips) or electroplated hard gold (0.5–2μm gold) for high-wear scenarios (e.g., frequent-insertion connectors).

Structural Flexibility: Supports 2–32 layers (typical 6–12 layers for complex systems) with standard thickness of 1.6mm (customizable 0.8–3.2mm, tolerance ±0.1mm); inner copper thickness of 0.5oz (≈17.5μm) and outer copper thickness of 1oz (≈35μm) (upgradable to 3oz for high-current modules like industrial PLC power units).

Technical Performance: Meeting High-Precision Requirements

To ensure compatibility with high-speed, high-reliability systems, Gold plated PCB adheres to rigorous technical standards:

Dielectric Constant: 4.2–4.7 (@1MHz for FR-4 base), minimizing signal delay in data transmission;

Impedance Control: 50Ω±10% (single-ended) / 100Ω±10% (differential pair), ideal for 5G RF signals and medical imaging data transmission;

Fine Wiring: Minimum line width/spacing of 3–5mil, enabling integration of dense components (e.g., aerospace control chips).

Industry Applications: Trusted in Critical Sectors

Gold plated PCB is widely used in fields where failure is not an option:

5G Telecom: Powers 5G base station RF modules, with gold plating reducing signal insertion loss to ensure stable 10Gbps+ data throughput;

Medical Equipment: Used in ultrasound machines and diagnostic scanners, where anti-corrosion gold plating meets medical-grade hygiene and long-term reliability requirements;

Aerospace: Integrated into satellite communication modules, withstanding extreme temperatures (-55°C to +125°C) and vacuum environments;

Industrial Automation: Equips PLCs and robotic control units, resisting oil, dust, and humidity in factory settings to maintain 24/7 operation.
