The Bare Board Test Probe is a critical component used in the testing and inspection of bare printed circuit boards (PCBs) before they are populated with electronic components. It ensures that the PCBs meet the required electrical specifications and functionality.

During the mounting process, the probe requires specific hole sizes to be accommodated properly. For this particular probe, the recommended mounting hole size is Φ 0.75 /.0296". This precise hole size ensures a secure fit for the probe, enabling accurate testing and measurements.

The Bare Board Test Probe, specified as CPM-20/R-20, follows specific specifications for optimal performance. The recommended minimum center distance between probes is 1.0 (.0394"), providing adequate spacing for reliable electrical connections and preventing any interference.
