## About PC Test Points
PC test points are fundamental passive components that provide a secure and accessible location to make temporary electrical connections to a circuit for testing, debugging, or calibration purposes. They are soldered directly onto a PCB, offering a more reliable and durable alternative to probing directly on tiny surface-mount component leads or fragile traces, which can easily be damaged.

The importance of using dedicated test points cannot be overstated in both development and production environments. They protect the integrity of the circuit board, increase the speed and accuracy of testing procedures, and enhance the overall serviceability of the final product. From simple voltage checks to complex automated testing, test points are a vital link between the physical circuit and diagnostic equipment.

## Packaging
This product is supplied in **Bulk** packaging.
