Silver-plated phosphor bronze PCB test terminals
Silver-plated phosphor bronze PCB test terminals are subjected to repeated, multiple press-contacts by probes during testing. Phosphor bronze ensures the terminals maintain excellent contact force and shape after tens of thousands or even hundreds of thousands of insertion/removal cycles without permanent deformation, guaranteeing reliable connections.

Primary Applications
Our terminals serve as essential components in automated testing and product lifecycle management, primarily used in:
In-Circuit Testing (ICT): At the end of production lines, spring-loaded probes (Pogo Pins) on test fixtures precisely contact these terminals to rapidly verify solder joints, component values, short circuits, and open circuits on circuit boards. This is a critical step in ensuring factory-quality standards.
Functional Test (FCT): Powering the circuit board and simulating real-world operating conditions to verify overall functionality. Test terminals often serve as access points for power, signals, and programming interfaces.
System Programming and Burning: Used for firmware burning or updating programmable devices such as microcontrollers and memory chips on circuit boards.
Debugging and Maintenance: During R&D or post-sales service, engineers can connect oscilloscopes, logic analyzers, multimeters, etc., to these terminals for convenient measurement of critical signals and voltages to diagnose issues.
Long-Term Monitoring Interface: In equipment requiring on-site data acquisition or monitoring, these terminals can serve as temporary data extraction interfaces.
Simply put, it acts as a “standardized, highly reliable” bridge between the circuit board and external testing/programming equipment.
