Spring Probe Advantages

Why spring-loaded contact probes are essential for modern electronic testing

Controlled Travel

Precision spring mechanism compensates for PCB warpage and height variations while maintaining optimal contact force

Consistent Force

Calibrated springs deliver repeatable contact pressure throughout the probe’s lifetime, ensuring test accuracy

Low Wear

Smooth plunger action minimizes friction and wear on both probe and test pad for extended service life

Frequently Asked Questions

What is the typical lifespan of spring probes?

Spring probes typically last 100,000 to 1,000,000 test cycles depending on the design, spring material, and operating conditions. High-quality probes with proper maintenance can exceed these ratings. Factors affecting lifespan include contact force, travel distance, and test environment.

How do I select the right spring force?

Spring force selection depends on your test requirements. Light forces (10-50g) suit delicate components, medium forces (50-150g) work for most applications, and heavy forces (150-500g) handle power testing. Consider pad size, oxide layers, and potential PCB damage when choosing force.

Can spring probes handle high currents?

Yes, high-current spring probes are available for power testing applications. Standard probes handle 1-3A, while specialized designs support 5-30A or more. High-current probes feature larger contact areas, heavier springs, and enhanced thermal management to safely handle power loads.

What plating options are available?

We offer gold, nickel, and tin plating options. Gold provides lowest contact resistance and best corrosion resistance for high-reliability applications. Nickel offers good durability at moderate cost. Tin is economical for standard testing. Plating thickness can be customized to requirements.

Do you provide custom probe designs?

Yes, we specialize in custom spring probe design and manufacturing. We can customize diameter, length, travel, spring force, tip style, plating, and mounting configuration to match your specific test fixture requirements. Our engineering team provides complete design support.

How do spring probes compare to solid pin probes?

Spring probes offer significant advantages over solid pins: they compensate for PCB height variations, prevent pad damage through controlled force, maintain consistent contact throughout their lifetime, and enable faster testing by eliminating the need for precise fixture height adjustments.
