Causes of quality problems of spring needle

　　Spring pin is usually used in mobile phones, communications, cars, aerospace and other electronic equipment for high-precision connection. Because the spring pin is a very fine electrode and its volume can be ensured to be very small, it can reduce the net weight of RF connector, save indoor space, and clean up the appearance of commodities (such as ultra-thin mobile phones, intelligent wearable devices, etc.) Unmanned aircraft, service robots, etc.).

　　In the process of spring mould thimble electroplating, gold plating process has a significant key influence on the electroplating process of spring mould thimble due to its high requirements of electrical equipment characteristics. At present, barrel plating and vibration plating are still used in the hole plating of many other pin hole parts, except for some spring mould thimbles with material. In recent years, with the development of connector volume more practical, the quality problems of electroplating products in the holes of pinhole loose parts gradually appear, and the quality requirements of customers for gold layer are also higher and higher. Some customers even achieve a particularly harsh level for the appearance quality of gold layer. In order to ensure the quality of connector electroplating layer, these common product quality problems have always been important to improve the quality of connector electroplating. The reason that this kind of product quality problem causes and everybody discusses below.

　　1. Abnormal tone of gold layer

　　The color of electroplated coating of spring mould thimble is different from that of all normal gold layer, or the color of gold layer of different parts in the same supporting facilities is different.

　　2. Hazard of raw material residue

　　When the residue brought by the chemical materials added with the plating solution exceeds the bearing level of the plating solution, the tone and chroma of the gold layer will be quickly damaged. If the organic chemical residue is harmful, the gold layer will be dark and flowery. The dark and flowered parts will not be fixed. If the residue of metal material is affected, the reasonable range of current intensity will be reduced. The Hall cell experiment shows that the medium and low current intensity of the test piece is not bright or the high-grade plating is not bright, and the medium and low-end coating is not bright, which shows that the coating on the plated piece is red or even black, and the color change in the hole is obvious.

　　3. Excessive current intensity

　　It is better than the calculation error of the floor area of the parts in the plating bath. The marked value exceeds the specific area, which makes the electroplating current too much, or the vibration amplitude is too small when using vibration plating gold, so that all or part of the gold coating crystal in the bath is not smooth, and the gold layer turns red.

　　Spring mould thimble is a kind of RF connector, its function is simply to have a connection effect. Spring mold thimble can be formulated according to the specific work requirements, and different specifications and models can be selected in the formulation. The key function of spring mould thimble is connection. The spring mould thimble can keep constant electric flow in work, and the electric flow can be customized according to customer satisfaction according to the size. Spring mould thimble has excellent elasticity and retractability, which plays a key role in connection.
