Chip metal shield, how to choose material to have more shielding effect + stamping appearance is as smooth as jade

The chip metal shield mold design manufacturer Hardware said that the mobile phone shield is a cover with a metal shielding function to shield the signal interference of electromagnetic waves. In the selection of raw materials, most of the materials are selected with stable shielding performance and easy to tin. So which material can be selected for the customized shielding cover to have a better shielding effect? The following Xiaoshuo will take you to understand: 1. Tinplate material, which is an iron material with a tin-plated surface layer, which can be tinned and has a shielding effect. But it is easy to rust. 2. Zinc-tin-nickel alloy, a material originating from Japan, that is, in the nature of iron, an electroplated layer of zinc, tin, and nickel is added. It can be tinned, and it also has a shielding effect. But the essence is still iron, and there is also the problem of rust. 3. Foreign white copper is one of the most used raw materials so far. The shielding effect is good, and the tinning performance is good. Many customers use this material when designing. Of course, there are some other materials, such as: copper, brass, and then electroplating for shielding cover, and some aerospace fields, using aluminum for shielding. Hardware, 15 years of focusing on chip metal shields, 5,000 square meters production workshop, hundreds of precision processing and production equipment, more than 20 Ru0026D and design engineers. The monthly processing capacity of 100+ sets of molds, the daily production capacity of 3 million punching times, the stamping accuracy can reach 0.01mm, and the 16 quality inspections are strictly controlled. It can quickly solve the time-urgent problem of stamping parts, solve the problem of stamping accuracy, and solve the problem of production quality for you. Choose, choose rest assured!
