Longhua shielding cover, the knowledge of shielding cover will take you to understand +3.0 precision stamping design system [hardware]

Hello everyone, I am the hardware shield manufacturer hardware responsible for the production of Longhua shielding covers. Today I will bring you some knowledge about shielding covers. Let’s take a look! In order to prevent external interference to sensitive circuits, a shielding cover is provided on each sensitive circuit in the prior art to prevent interference from EM1, signals and pulses. However, a printed short circuit board often includes multiple sensitive circuits, and the cost of each shielding cover is several thousand. Therefore, a shielding cover is provided on each sensitive circuit, which makes the traditional shielding cover packaging land structure production High cost. In order to prevent external interference to sensitive circuits, a shielding cover is provided on each sensitive circuit in the prior art to prevent interference from EM1, signals and pulses. However, a printed short circuit board often includes multiple sensitive circuits, and the cost of each shielding cover is several thousand. Therefore, a shielding cover is provided on each sensitive circuit, which makes the traditional shielding cover packaging land structure production High cost. In order to solve the above problems, the present utility model has designed and developed a shielding cover packaging structure. A shielding cover is welded on the printed circuit board. The shielding cover can cover a plurality of circuits to be shielded on the printed circuit board, and shield the The cover is divided into a plurality of cavities corresponding to the circuit to be shielded, and a shielding cover is used to shield the plurality of circuits to be shielded, so as to achieve the purpose of saving production cost. The price of the raw materials for the shielding cover varies greatly, and the materials used are also different, but the materials are only the following: stainless steel, nickel silver, tin bronze, brass, tinplate, etc., of which nickel silver, stainless steel, tinplate is the most used widely. The hardware and system are complete and formal, the team is stable, and there is a stepped reserve of technical personnel, which can respond in time when the order breaks out, and the after-sales service responds to customers 24 hours a day.
