Ball-pen probe

A ball-pen probe, often referred to as a ballpoint probe, is a type of precision tool used in various fields, particularly in electronics and material testing. It consists of a small, rounded tip that resembles the ballpoint of a pen. This design allows for precise contact with surfaces or materials, enabling accurate measurements or assessments. In electronics, ball-pen probes are commonly used for testing and troubleshooting printed circuit boards (PCBs) or other electronic components.
