What are Test Points components?

Test points are dedicated PCB features that allow probes to contact specific circuit nodes without damaging traces or components. They are essential for signal validation, in-circuit testing (ICT), and firmware debugging during the prototyping and manufacturing phases.

How to Choose Test Points Components

Select test points based on your probing method, assembly process, and physical board constraints.

  1. Mounting Style

    Choose SMT for automated assembly lines or through-hole for high-mechanical-stress environments.

  2. Probe Compatibility

    Ensure the geometry (loop, turret, or pad) matches your specific oscilloscope or ICT probe tips.

  3. Material & Plating

    Select gold or tin plating based on the required contact resistance and environmental exposure.

  4. Board Space

    Use low-profile or ultra-miniature points to minimize footprint impact on dense high-speed designs.

  5. Mechanical Stability

    Consider turret or post styles if the test point will be used as a wire wrap or frequent manual probe point.
