The Bare Board Test Probe is a vital component used in the testing and evaluation of bare printed circuit boards (PCBs). Its primary function is to ensure the quality and reliability of the PCBs before they are populated with electronic components.

During the mounting process, the probe requires a specific hole size to be properly installed. In this case, the recommended mounting hole size is Φ 0.75 /.295". This ensures a secure fit and proper alignment of the probe, facilitating accurate testing and measurements.

The Bare Board Test Probe, specified as CPM-201/R-201, adheres to specific specifications to ensure optimal performance. The recommended minimum center distance between probes is 1.0 (.0394"), providing adequate spacing for reliable electrical connections and avoiding any interference.

The probe has a full travel distance of 2 (0.787"), indicating the maximum distance it can extend during testing. With a current rating of 1A, it can handle electrical currents of up to 1 ampere without compromising performance. The contact resistance is specified as 120mΩ, ensuring low resistance and efficient signal transmission. The spring force can be adjusted between 30g and 80g, allowing flexibility based on the testing requirements.
