[Hardware] What details should be paid attention to in the function, design and installation of the mainboard white copper shield

For products such as mobile phones, transformers, routers, and other products, the nickel silver shields used in their functions, design, and installation have some experience summarized by engineers. What are they? Xiaoshuo will communicate with you about: 1. First of all, the cover of the white copper shielding cover is mostly made of stainless steel. It cannot be stretched, but can only be bent; the shielding bracket can be stretched, but the thickness of the bracket must be 0.20mm, height ≥1.25mm; 2. The minimum inner R angle at the corners of the nickel silver shield tensile piece must be at least 0.65mm, the minimum outer R angle must be at least 1.0mm, and the welding method should be flanged in 0.20mm or more; 3. The width of the flange trimming around the nickel silver shielding cover is Bu003d0.2mm (1 times the material thickness) to increase the flatness stability; the inner round corner R1 of the outer frame can be as small as R0.65mm, preferably R1.0mm or more is better, the drawing forming cannot have a right-angle sharp turn, otherwise the drawing will break; 4. The outer corner of the outer frame R2 u003d 1.0 mm, preferably R1.5mm or more is better; A size is not required It is less than 0.7mm, preferably 1.0mm or more. The daily production capacity of hardware and foreign cupronickel shields is 3 million strokes. 16 quality inspection procedures are checked at all levels. It is a reliable manufacturer that can solve your quality and production capacity.
