The spring thimble, also known as the probe, is the contact medium for electrical testing and an advanced precision electronic hardware component. When used for circuit board testing, it is divided into pogo pin and ordinary pin. When using pogo pin, the test mold must be made according to the wiring of the tested circuit board. Generally, the mold can only test one type of circuit board. Most pogo pin manufacturers produce different types of pogo pins. There is a layer of gold on the surface of the pogo pin to improve its corrosion resistance, mechanical properties and electrical properties. Pogo pin is widely used in aviation, aerospace, military communications, military electronics and other fields due to its small size, high precision and light weight.
In recent years, electronic products have developed in the direction of lighter weight and portability. The spring thimble manufacturers are second to none. The stable contact resistance of the spring thimble ensures the stability of electronic equipment, and the spring thimble needs to be plugged and used repeatedly. The life span can reach about 50,000 times. In addition, it is waterproof, moisture-proof and shock-proof, so the production and development of spring thimble is another milestone in my country's electronic products.
