Set-top box shielding cover, what are the knowledge of shielding cover + 3 million punching next day production capacity

Hello everyone, I am a hardware shield manufacturer responsible for the production of shielding covers for set-top boxes. Today, Xiaoshuo of Hardware brings you some knowledge about shielding covers. Let’s take a look! Shield manufacturers must pay attention to the following aspects after the design of the shielding layer of the high-frequency transformer is completed to ensure the effect of the application. The novel has sorted out some information, and let’s take a look at it: First of all, for the internal shielding layer of a high-frequency transformer, the main function is not to shield the leakage magnetic field, but to shield the primary and secondary high-frequency electric field signals, so the high-frequency The main function of the transformer shielding layer is to connect to a quiet potential to ensure the connection effect of the primary side ground wire and the connection effect of the high voltage end. If the copper foil shield cuts off the path of the primary and secondary stray capacitance, it will form a capacitance. When the winding shield cuts off the primary electrophoresis path, due to the difference in the number of winding turns, the effect on the winding direction and position will be very obvious. difference. It can effectively enhance the shielding effect, so the thickness of the copper foil is generally about 0.05 mm, and the width should be smaller than the width of the primary winding. Through this design method, it can be ensured that there is no short circuit at both ends of the shielding layer. In the production process, both ends of the copper foil must be insulated with insulating tape. In the process of using the winding as the inner shield, 0.1 mm~0.3 mm enameled wire must be used for meticulous winding, and the insulating tape must be used to fix the closing position. Can enhance the insulation effect of the shielding layer. Ms. Zheng's company in Huizhou is a mobile phone communication product. There is a mobile phone shielding product that needs to be exported abroad. The specific plan has been implemented. The customer needs to send 2K goods within a week. The company was stumped. The mold required for this shielding cover has not been opened yet, and several factories have not been contacted to find a suitable choice. In the end, I found our hardware after several twists and turns. After some discussion, I didn't instigate any more, and I directly got the drawings for mold making. It took only 5 days to make the mold of this shielding cover, and on the 6th day, the finished 2K goods were delivered to Ms. Zheng’s company on time. Hardware, 15 years of focusing on set-top box shielding, has a 5000 square meter production workshop, has more than 20 mold Ru0026D and design engineers, seven precision stamping core technology patents, 20000+ sets of stamping die customized production experience, hundreds of precision processing and production equipment, The precision of silk-like stamping can reach 0.01mm, the daily production capacity can reach 3 million stamping times, 16 quality inspection layers are strictly controlled, one-to-one customized parts tracking service, customized stamping parts are evaluated in 1 hour, and stamping parts are proofed in 2 days and 4 days. Delivery within 2 days from the mold can speed up the time to market for customers' new products in 5-9 days. Improve the assembly production efficiency by 17% and increase the product qualification rate by 1.3%. It is a partner of many Fortune 500 companies. It can quickly solve the time-critical problems of stamping parts processing customization, solve the stamping accuracy problems, and solve the production quality problems for you.
