15 years of precision stamping parts factory tells you how to choose the type of shield material

Shields are used more and more in electronic products, but because of the cost of raw materials and the different signal requirements of each product, each company has its own consideration in the selection of materials. At the same time, because the price of raw materials varies greatly, the materials used are also different, but the materials are only the following: stainless steel, nickel silver, tinplate, etc., of which nickel silver, stainless steel, and tinplate are the most widely used. The advantages and disadvantages of various shielding cover materials are as follows: Nickel-nickel alloy: The shielding effect is slightly worse, it is softer, the price is more expensive than stainless steel, and it is easy to tin. At present, most of the shielding covers are made of nickel silver. Stainless steel: good shielding effect, high strength, moderate price; but difficult to tin (it can hardly be tinned without surface treatment, it can be improved after nickel plating, but it is still not conducive to the patch) Tinplate: the shielding effect is the worst, but the upper Good tin, low price. In the above analysis of several products, nickel silver is used for its better shielding effect, better corrosion resistance and good welding performance. Although the price is more expensive than stainless steel, most of them use nickel silver as The raw material of the shield.
