Maoming pcb shield, 3.0 precision stamping design system + hundreds of advanced and precise stamping processing equipment

Hello, everyone, I am a precision shield manufacturer hardware responsible for the production of PCB shields in Maoming. Today I will bring you some knowledge about shielding covers. Let’s take a look! The inner and outer surfaces of the pcb shielding cover, and the inner and outer sides of the bend are crushed: there are two situations, (1) small hole skipping waste, large hole skipping waste: long-term production causes the punch blade to wear out and the gap becomes larger, and the waste cannot be stuck. Crushing caused by headband ejection surface (2) Powder crushing: The gap between the punch and the knife edge is too large or too small to cause the powder to scatter on the die surface. When the material passes through the leveler and the feeder, the product will be directly crushed by the dust and fine iron filings in the machine. In order to prevent external interference to sensitive circuits, a pcb 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.

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 PCB shielding cover is welded on the printed circuit board. 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.
