Problems solved by technology

The cost of the mold and the cost of mold maintenance are also high, especially for products that require a small number of products, the cost of the mold alone is very high
However, during the use of the existing shielding cover, the legs of the shielding cover product are generally welded to the parts that need to be protected, such as the PCB board, with a metal welding process. The process is complicated and the assembly cost is high.

Abstract

The invention discloses a shielding case and a manufacturing method of the shielding case. The shielding case comprises an insulating case body and a metal conducting layer arranged on the outer side of the insulating case body. The thickness of the metal conducting layer is 0.001mm-0.003mm. The shielding case and the manufacturing method of the shielding case have the advantages that the shielding case is formed by arranging the metal conducting layer on the insulating case body, the structure is light and simple, working procedures are simple, processing efficiency is high, and assembly cost is low.

Description

technical field [0001] The invention relates to electromagnetic shielding technology, in particular to a shielding cover and a preparation method thereof. Background technique [0002] In the field of electronic manufacturing, shielding covers have a wide range of applications, mainly in mobile phones, GPS (positioning system) and other fields. Use the shielding cover to surround the components on the PCB board (printed circuit board) and electronic components such as LCM (liquid crystal module), circuits, assemblies, wires or interference sources of the entire system to prevent the interference electromagnetic field from spreading outward and prevent them from being affected. The influence of the external electromagnetic field, so as to achieve the purpose of anti-electromagnetic interference. The material of the existing shielding cover is generally processed by metal materials such as stainless steel, nickel-nickel copper, and nickel-plated steel plates of different thic...
