Baoan mobile phone shielding cover, let you know which areas need shielding cover + 16 strict quality inspections to ensure the quality of each [5

Hello everyone, I am a precision shield manufacturer hardware responsible for the production of shielding covers for Baoan mobile phones. Today I will bring you some knowledge about shielding covers. Let’s take a look! The inner and outer surfaces of the mobile phone 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 fall off 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. The mobile phone shield is a metal shell mounted on the electronic motherboard. The interference source of the components, circuits, assemblies, cables or the entire system is surrounded by its own shield to prevent the interference electromagnetic field from spreading out and pass the board. The upper device is isolated to achieve the effect of shielding various electromagnetic devices, so that it can minimize crosstalk and sensitivity without affecting the operating speed of the system.
