Reliable PCB Test Pins for Accurate and Repeatable Electronics Testing
Test Pins
Reliable PCB test pins for accurate, repeatable probing and diagnostics from prototype to production.
What are Test Pins?
Test pins are small metal terminals soldered to a PCB to provide secure access points for measurements and quality checks. They allow engineers and technicians to probe signals, verify voltages and perform fault-finding without stressing components or traces.
- Low-cost, robust access for oscilloscopes, probes and ATE fixtures
- Speeds up development, production test and servicing
- Consistent probe repeatability compared with ad-hoc wire stubs.

Test Pin Selection Guide
Choose the right style for your probing method, available space and expected number of test cycles.
| Style | Best For | Key Benefits |
|---|---|---|
| Turret | Repeated clip-on probing; general test access | Robust post, easy hook/clip connection. |
| Loop | Hook probes; quick temporary wiring | Positive engagement for hooks and grabbers. |
| Miniature | Tight layouts; low-profile designs | Smaller footprint, reduced intrusion. |
| Gold-plated | High cycle count; low contact resistance | Improved conductivity and corrosion resistance. |

Test Pins FAQs
What’s the difference between a test pin and a test point?
In PCB terminology, a test pin is the actual metal terminal soldered onto the circuit board. It provides a reliable mechanical and electrical connection point for test equipment. A test point is the location on the PCB layout that has been designated for measurement. In practice, engineers use the terms interchangeably, but technically the pin is the component, while the point is the spot on the board.
Which style should I choose?
The right choice depends on how you intend to test your circuit:
- Turret pins - robust, upright posts that allow repeated use with clip leads and test hooks.
- Loop pins - ideal when you want to connect probes with hooks or temporary jumper wires.
- Miniature pins - perfect for space-limited designs where a low profile is essential.
- Gold-plated pins - recommended when you need low contact resistance and long-term corrosion protection.
Consider the space available on your PCB, the probe type you plan to use, and the expected number of test cycles.
Do you offer bulk packs?
Yes. Test pins are available in small packs for prototyping and educational use, as well as larger bulk quantities for production runs. Buying in bulk ensures consistency across projects and offers better value. Contact our sales team for pricing tailored to your order size.
Can I add test pins late in the design?
In many cases, yes. If your PCB has accessible copper pads or test pins can often be added during assembly to provide measurement access. However, for best results it is recommended to plan test pins into the PCB layout from the beginning, as this ensures the correct spacing, clearance and probe accessibility. Adding them early also helps reduce debug time later in the project.
Are test pins reusable?
Test pins themselves are permanent components once soldered into a board, so they are not typically removed and reused. However, their connection function is reusable: probes, clips and hooks can connect and disconnect from the same test pin many times without damaging the PCB. This repeatability is one of the key advantages of installing test pins.
Where are test pins most commonly used?
Test pins are widely used in prototyping laboratories, electronics manufacturing lines, educational settings and service departments. They provide quick and reliable access for multimeter checks, oscilloscope probing, automated test equipment and in-circuit test fixtures. Any environment where PCBs need accurate, repeatable testing can benefit from test pins.
