Dongguan mobile phone shielding cover, a number of precision stamping core technology patents + 16 strict quality inspections to ensure the quality of each

Hello everyone, I am a hardware manufacturer of precision shielding covers that is responsible for the production of shielding covers for mobile phones in Dongguan. Today I will bring you some knowledge about shielding covers. Let’s take a look! The advantages and disadvantages of the raw materials of the mobile phone shielding cover are as follows: Silver nickel: 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 mobile phone 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 Tin is good and cheap. Tin bronze: the shielding effect is slightly poor, and the tin is to be checked. Brass: the shielding effect is slightly poor, and the tin is to be checked. In the analysis of the above several products, nickel silver is due to its better shielding effect, and It has 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 shielding cover. Mobile phone 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.
