Test Points, Spring Probes (pogo pins) and Receptacles for PCB testing

This category includes components dedicated to PCB testing and verification: test points for measurement access, spring probes (pogo pins) for repeatable temporary contact, and receptacles used to locate and interface probes inside fixtures. They are key elements to shorten troubleshooting time, standardize inspection steps and improve contact consistency during tests.

Typical B2B applications

• Production test fixtures (functional test, in-circuit test, end-of-line)
• Test benches, jigs and tools for electronics labs
• Maintenance and repair: quick access to signals and power rails
• Prototyping and PCB debugging with dedicated measurement points
• Repeatable testing across lots and PCB revisions (standardization)

What test points, pogo pins and receptacles do

Test points provide fixed measurement or programming access on the PCB. Spring probes create a pressure-based temporary contact, ideal for fast and repeatable connections in fixtures. Receptacles house and locate probes, improving stability and making wear parts easier to replace.

How to choose (practical criteria)

• Form factor and mounting: THT/SMT, orientation and available space on the PCB or in the fixture
• Pitch and placement: spacing between test points and mechanical tolerances of the tooling
• Travel and spring force: balance contact reliability vs stress on pads/PCB
• Tip style: match to pads, vias, pins or specific contact surfaces
• Electrical rating: current needs and contact resistance requirements
• Materials and plating: selected to improve contact stability and lifetime
• Lifecycle and maintenance: expected cycles and ease of replacement (with receptacles)

Operational benefits for production and service

Well-designed test access reduces rework and diagnostic time. Consistent pitch, travel and tip geometry improve repeatability and contact stability, helping both in-line testing and after-sales service workflows.

Frequently asked questions

Q: When should I use a test point instead of a spring probe?
A: A test point is ideal as a permanent PCB access point. A spring probe is preferred for temporary, repeatable fixture contact withou
