The Bare Board Test Probe is a vital component used in the testing and evaluation of printed circuit boards (PCBs). It plays a crucial role in ensuring the functionality and reliability of electronic devices.

During installation, the Bare Board Test Probe requires specific mounting hole sizes to ensure secure and accurate placement on the PCB. The recommended mounting hole size for this probe is Φ 1.4 /.0551". This size allows for precise fitting and ensures a stable and reliable connection between the probe and the PCB.

The Bare Board Test Probe, designated as CPM-1, comes with specific specifications that contribute to its effectiveness in PCB testing. The recommended minimum center distance between probes is 1.9 (.0748"), providing adequate spacing between the probes for proper testing and avoiding interference. The probe offers a full travel distance of 2.54 (0.1"), allowing it to make optimal contact with the PCB during testing. It has a current rating of 3A, ensuring it can handle the electrical demands of the PCB. The contact resistance of the probe is 50mΩ, indicating low resistance for reliable signal transmission. The probe exerts a spring force of 120g, providing sufficient pressure for consistent and reliable contact with the PCB.

The Bare Board Test Probe is constructed using high-quality materials to ensure durability and performance. The plunger is made of SK4 and is nickel plated, offering excellent wear resistance and electrical conductivity. The barrel is constructed of phosphor bronze and is gold plated, providing corrosion resistance and reliable electrical contact. The spring is made of stainless steel, known for its strength and durability.
