Spring needle in use, the need to test the circuit board according to the circuit board wiring situation to make test molds, and usually, a mold can only test a circuit board board; universal needle in use, only enough points to test the circuit board, so most of the current shenzhen rechargeable needle manufacturers will produce different types of shenzhen rechargeable needles.
Spring needles have a layer of gold on the surface, improving its corrosion resistance, mechanical properties, electrical properties. Because of the advantages of small size, high precision, light weight spring needle is widely used in aviation, aerospace, military communications and military electronics; secondly, also involves with our inseparable automobile, car navigation and other fields; in addition, medical equipment, wireless equipment, data communication equipment, etc. also have its figure.
