The Bare Board Test Probe is an indispensable tool in the field of electronics testing, specifically for evaluating the functionality and reliability of bare printed circuit boards (PCBs) before they are populated with components. This probe ensures that the PCBs meet the required standards and specifications.

During the mounting process, the probe requires a specific hole size for accurate and secure installation. In this case, the recommended mounting hole size is Φ 0.57 /.0225". This ensures a precise fit and allows the probe to make reliable electrical contact with the PCB.

The Bare Board Test Probe, specified as CPM-40/R-40, follows strict specifications to ensure consistent and accurate testing results. The recommended minimum center distance between probes is 0.75 (.0295"), providing proper spacing for efficient testing and minimizing interference between adjacent probes.

The probe has a full travel distance of 1.5(0.059") or 2.0(0.78"), indicating the maximum range of movement during testing. This versatility allows for thorough testing and analysis of the PCB's performance and functionality.
