The Bare Board Test Probe is an essential component used in the testing and validation of bare printed circuit boards (PCBs). Its purpose is to ensure the functionality and reliability of the PCBs before they are assembled with electronic components.

During the mounting process, the probe requires a specific hole size for proper installation. In this case, the recommended mounting hole size is Φ 0.7 /.0276". This ensures a secure and precise fit, allowing accurate testing and analysis of the PCB.

The Bare Board Test Probe, specified as CPM-30L-LL/R-30L-LL, follows precise specifications to deliver reliable and accurate results. The recommended minimum center distance between probes is 0.85 (.0335"), ensuring proper spacing for effective electrical connections and avoiding any interference between adjacent probes.

The probe has a full travel distance of 2 (0.787") or 4 (0.156"), indicating the maximum extent to which it can move during testing. This flexibility allows for various testing scenarios and enables comprehensive analysis of the PCB's performance.
