The probes are manufactured by imported precision lathes or precision molds for optimal performance. Selecting a high-quality test probe is a way to solve the problems of false open circuit, unstable resistance, short life, poor contact, electric spark generation, quick needle blackening, easy bending and wear during the test process, which can immediately improve the efficiency of the test department and reduce the cost of production. Probe materials: Generally used phosphorous copper, brass, beryllium copper materials after heat treatment nickel gold-plated products have high hardness, strong wear resistance, stable electrical conductivity and other characteristics; Probe spring: The use of stainless steel wire, piano steel wire, precision series of probes tested by the testing machine, the use of probe life testing machine, hardness testing machine, X-ray thickness gauge, strict detection of probe quality; Probe tube: the inner and outer tube walls are thickened and gold-plated, and part of the spring is gold-plated, which reduces the resistance value and is easy to contact to prevent oxidation reactions caused by long-term testing of the probe and the influence of external environment; The advantages of gold-plated probe: gold-plated probe can resist corrosion and is not easy to oxidize, and the thickness of the gold-plated layer usually reaches a certain thickness. For products with smaller and deeper holes in the needle tube, it is necessary to increase the gold plating thickness to plate bright holes, and the smaller the resistance value of the probe, the better the conductivity. At the same time, the side holes of some blind holes can be increased to form a return flow of gold-plated water in the inner holes to ensure uniform gold-plated thickness. The thicker the gold layer, the better the electronic properties and wear resistance of the product, and the better the service life. The downside is that the thicker the thickness, the higher the price. Gold plating thickness is independent of spring life. The life of the spring is related to the test conditions, such as the current and voltage of the pipe, the ambient temperature and humidity, etc., if the gold is thin, the needle is prone to black, and the conductivity is not good. |
