TV shielding cover, take you to understand what is a shielding cover + Fortune 500 corporate partners

Hello everyone, I am a hardware shield manufacturer responsible for the production of TV shielding covers. Today, Xiaoshuo of Hardware brings you some knowledge about shielding covers. Let’s take a look! Shielding cover design check points: 1. The overlapping area of u200bu200bthe shielding cover and the shielding bracket (including the side wall and the top surface) must not have insulating glue or insulating paint. Insufficient contact prevents noise leakage; there are high short-circuit high device positions at the edge, which can be allowed to extend to the edge of the top surface to ensure insulation requirements; 2. The clearance between the PCB shield and the circumference of the electronic component is 0.5mm, and the clearance in the depth direction is at least 0.3 mm (less than 0.2mm plus insulating tape or spraying insulating paint) to prevent short circuits; 3. The distance between the edge of the pads of the two welding shielding brackets is not less than 0.6mm; 4. The SMT shielding bracket should be designed with a suction platform, the specification is less than 30* 30mm, the suction platform requires ≥φ5.0mm, the specification is greater than or equal to 30*30mm, and the suction platform requires ≥φ6.0mm; 5. For chips above 5*5 under the shielding cover, the shielding bracket needs to reserve a dispensing needle space for easy chip Dispensing. (It must be confirmed with the process); 6.2D drawings need to add insulation paint reliability test requirements; 7. The distribution of the fixing screws of the laser spot welding shielding cover must be balanced, and the bulging and deformed parts must be fixed with screws. For the nut mounted on the PCB board, the diameter is φ3.0; 8. The flatness of the laser spot welding shielding cover must be within 0.15mm; 9. The laser spot welding shielding cover rib and the nut are not allowed to be cloth within 0.5. Avoid short circuit; 10. Laser spot welding shield, the distance between bracket shrapnel is 6.0mm, and the width of rib is 0.8mm. 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 anymore, 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 focus on TV shielding, with 5000 square meters production workshop, more than 20 mold Ru0026D and design engineers, seven precision stamping core technology patents, 20000+ sets of customized stamping mold production experience, silk-like stamping accuracy can reach 0.01mm, The daily production capacity is 3 million punching times, 16 quality inspection layers are strictly controlled, stamping parts are proofed in 2 days, 4 days are out of mold and delivered in 2 days, which can speed up the time to market for customers' new products in 5-9 days. 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.
