the effects of pogopin gold plating thickness on the cost-life of salt spray?

　　The needle and barrel of the pogopin spring probe Pin needle are generally made of brass, and copper is a very active metal material. It will react with oxygen in the air when exposed to the air, and the surface will be oxidized by the air. Therefore, pogopin spring needles must be surface electroplated; the more common one is generally to do surface gold plating. Do you know how thick the pogopin gold plating is more appropriate? What is the impact of salt spray on the cost life of the product?

　　The gold-plating process occupies a significant key influence in the pogopin connector electroplating process. Generally, the thicker the pogopin gold plating, the better the effect and the higher the unit price. Therefore, the thickness of the gold plating is directly related to the cost of the Pogopin. The commonly used pogopin gold plating thickness on the market is average It is 3u". Now many customers consider the cost of gold-plated 1u" and use it. In fact,  3u" and 1u" do not have much difference in compression reliability in terms of service life, but the thick salt spray and wear resistance of the gold-plated layer are better. The needles of these two thicknesses of salt spray Pin needles can last 48 hours and 24 hours, respectively.

　　With the development of mobile products, led by mobile phones, in the direction of miniaturization, thinning, and high performance, the connection between the pogo pin connector custom display assembly and the substrate has become more complicated, and the precision and compact research and development of the pogopin connector industry has become more and more popular. pay attention to.

　　Because pogopin is a very fine probe, it can be used for precision connectors, reducing the weight and volume of the connector, making the connector more exquisite and beautiful, and its main advantages: stable dynamic impedance, large current, long life, small size, and customization Strong performance; the use of spring thimble connectors can easily achieve waterproofing, and the electroplating process used has anti-corrosion function, which can effectively prevent the pogo pin thimble from vulcanization, oxidation and corrosion in the working environment.
