Application Areas
1. Consumer Electronics (Widest Application)
This is the largest market for gold-plated brass terminals, owing to their outstanding overall cost-performance ratio.

Smartphones/Tablets: Battery connectors, SIM card slots, terminals for certain board-to-board connectors.

Laptops: Inner core terminals for external ports like USB, HDMI, and power connectors.

Audio/Video Equipment: Internal contacts for 3.5mm headphone jacks, RCA connectors, and HDMI ports.

Home Appliances: Control board connectors for smart appliances and battery terminals for remote controls.

2. Communications and Data Transmission
A field demanding high signal integrity, where gold’s stability and low resistance are critical.

Network equipment: Contacts in RJ45 network interfaces (Ethernet jacks).

Fiber optic communication equipment: Electrical interface sections of high-speed backplane connectors and optical modules.

Base station equipment: Central conductors in certain RF coaxial connectors (especially for low-power applications).

3. Automotive Electronics
In vehicles, it is primarily used in the “body” area where current and reliability are required but the environment is relatively mild.

Body Control Modules: Connectors for door/window controls, seat adjustments, and lighting systems.

Infotainment Systems: Connection terminals for audio, navigation, and display screens.

Low-voltage wiring harnesses: Plug-in connectors for instrument panels, climate controls, etc.

Note: High-temperature, high-vibration areas like engine compartments may use higher-performance phosphor bronze or beryllium copper with gold plating.

4. Industrial Control & Instrumentation
Applications requiring reliable connections to ensure stable system operation.

I/O module interfaces for PLCs (Programmable Logic Controllers).

Measurement instruments: Test ports and internal connections for oscilloscopes, signal generators.

Board-to-board and wire-to-board connectors on automation equipment control panels.

5. Medical Electronics
Strict requirements for reliability and corrosion resistance (resistance to disinfectants).

Monitoring equipment: Electrode contacts and data interfaces for ECG monitors and blood pressure monitors.

Battery connectors and data ports for portable medical devices.
