Pogo pins generally refer to an electronic hardware material. It refers to a thimble with compressive elasticity, which is often used for connection and conduction.

Stuck pins and shucked pins
Stuck pins and shucked pins refer to undesirable phenomena such as unsmooth compression encountered during use of the spring loaded pin. The stuck pin is seriously bad. Improper pre-pressure causes the pogo pin to not work properly. The specific reasons can be analyzed from the aspects of structural design, assembly process, work schedule, electroplating process, manufacturing process and welding methods.

Premature failure of pogo pin
Premature failure of spring pin generally refers to the failure of the spring in the pogopin to rebound before it is officially used. Typically, if a customer experiences premature failure when using a spring loaded pin. It is most likely caused by excessive compression or side loading. Most customers who are interested in the products will start by pressing them with their hands, exerting extreme force on the plunger to form a retaining spring. Once the spring is secured, the plunger will no longer return to its original position. Side loads or axial loads will also contribute to bonding or adhesion, creating a pin shaft that jams the PogoPin. Therefore, the recommendation is to protect the plunger as much as possible from any side loads and excessive compression before the spring pin is used. Customers can easily resolve this issue by creating mechanical stops or limiting the compression capabilities of the application.

Contact produces sparks
Instantaneous failure: spring loaded pin instantaneous interruption refers to the phenomenon of pogo pin instantaneous circuit breakage when vibration, impact, collision, etc. occur during the use of the pogo pin connector, which affects the electrical continuity of the contact pair. To judge the spring loaded pin instantaneous interruption, you must first look at how long the instantaneous interruption lasts. Generally, the prescribed instantaneous interruption times are 1μs, 10μs, 100μs, 1ms and 10ms. The second thing to note is to check the pogo pin contact timing for voltage drop. It is now generally believed that when the voltage drop across the closed contact pair (contact pogo pin) exceeds 50% of the power supply electromotive force, it can be determined that the closed contact pair (contact) has failed. In other words, there are two conditions for judging whether a pogo pin instantaneous interruption occurs: duration and voltage drop, both of which are indispensable.
