How an electronic product can measure the impact of its radiation, the key lies in the metal shield.
　　The regular electronics companies will consider how to reduce radiation when producing electronic products to meet the increasing demands of consumers.
　　Smaller electronics companies are more concerned about saving production costs and achieving more profitable goals. Therefore, some small electronics companies will reduce the radiation-reducing metal shields, resulting in the production of electronic Product radiation In the case of the same hardware facilities, health and environmental protection standards do not have the standard of a regular enterprise.
　　Cell phone shields use shields to enclose the components, circuits, assemblies, cables, or interference sources of the entire system to prevent them from spreading out; the shields are used to enclose the receiving circuit, device, or system to protect them from external electromagnetic fields. Impact. The material of the shield is usually 0.2mm thick stainless steel and white copper. Among them, nickel white copper is a kind of metal shielding material that is easy to tin. Consider the sucker design when using SMT stickers. The flatness of the mobile phone metal shield produced by the company is strictly controlled within the tolerance of 0.05mm to ensure its easy tinning performance and excellent shielding effect.
