Luotian transformer shielding covers, set up 16 strict quality inspections to ensure the quality of each one + the stamping flatness of the shielding cover reaches 0.07

Hello everyone, I am a precision shield manufacturer hardware responsible for the production of Luotian transformer shields. Today I will bring you some knowledge about shields. Let’s take a look! In order to prevent external interference to sensitive circuits, a transformer shield 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-mentioned problems, the present utility model has designed and developed a shielding cover packaging structure. A shielding cover is welded on a printed circuit board. The transformer shielding cover can cover a plurality of circuits to be shielded on the printed circuit board, and use the shielding plate to The shielding cover is divided into a plurality of cavities corresponding to the circuit to be shielded, and one shielding cover is used to shield the plurality of circuits to be shielded, so as to achieve the purpose of saving production cost. All companies engaged in the production of transformer shields are mainly based on foundry. Some private-owned enterprises with independent brands have introduced, digested, and absorbed foreign advanced technologies, and have accumulated technology and talents, and have gradually formed an independent research and development as the core, The development path of enterprises participating in international market competition, the business model began to enter the brand era from the foundry era. 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 after-sales service responds to customers 24 hours a day.
