When using the spring needle, it is necessary to make a test mold according to the wiring situation of the tested circuit board. Usually, only one circuit board can be tested by one mold. The universal needle only needs enough points to test the circuit board when it is used, so most Shenzhen charging needle manufacturers will produce different models of Shenzhen charging needles at present.
The surface of the spring needle is plated with a layer of gold, which improves its corrosion resistance, mechanical properties and electrical properties. Spring needle is widely used in aviation, aerospace, military communication, military electronics and other fields because of its small size, high precision and light weight. Secondly, it also involves cars, car navigation and other fields that are inseparable from us; In addition, medical equipment, wireless equipment, data communication equipment, etc. It also exists.
