Application Areas
Our 0.07mm phosphor bronze single-sided silver-plated spring contacts, with their outstanding conductivity, elasticity, and miniaturization capabilities, are widely used in precision electronic devices with extremely high demands on space and performance:

Micro/Precision Connectors: Used for battery connections, mainboard-to-subboard connections, and FPC connections in ultra-thin devices like smartphones, smartwatches, TWS earbuds, and tablets. The 0.07mm thickness allows seamless integration into extremely constrained spaces.

RF Shielding and Grounding: Serves as contact springs within shielding enclosures or grounding points for devices, ensuring effective electromagnetic shielding (EMI/RFI) and electrical grounding. Single-sided silver plating guarantees low-impedance contact surfaces.

Precision Switch Contacts: Acts as the core contact and spring-loaded component in miniature switches requiring high reliability and long lifespan, such as side buttons and detection switches.

Test Fixtures and Probes: Function as high-frequency, low-loss test probes or contact points in fixtures for chip testing and circuit board testing (e.g., ICT, FCT testing).

Wearables and Medical Devices: Provide stable electrical connections in applications demanding extreme size and reliability constraints, such as ECG monitoring patches, hearing aids, and implantable medical devices.

High-Precision Optical Modules: For connecting moving parts in components like smartphone camera modules and LiDAR systems, where the spring sheet must not interfere with optical paths while ensuring stable signal transmission.
