What are Pogo-Pins?

Pogo-pins, or spring pins, are commonly used in clamshell fixtures to access test points and depopulated SMT pads on a board. While clamshell fixtures are essential for complex applications with high pincounts to balance forces, simpler applications can benefit from fixed probes without the need for a clamshell. For boards with fewer test points, a cost-effective approach using pogo-pins with cables can replace the clamshell, allowing for a mix of automated and manual testing.

Clamshells are optional.

A single-sided pogo-pin fixture, which includes optional toggle clamps or thumbscrews for securing the unit under test (UUT), enables full access to the board. This setup allows a technician to flip and manually probe the board while keeping cables connected. The pogo-pin plate is modular, adapting test points to a cabled form, offering flexibility and ease of replacement for design changes. This makes the system ideal for early deployment or frequently modified designs.
