Circuit board shielding cover, what are the experiences of designing shielding cover + stamping accuracy can reach 0.01mm

The manufacturer of the circuit board shielding cover said that the foreign white copper shielding cover selected for mobile phones, transformers, routers and other products has some experience summarized by engineers in its function, design, and installation. So what experience have been summed up? The following Xiaoshuo will know about you based on practical experience: 1. First of all, the cover of the white copper shielding cover is mostly made of stainless steel. It cannot be made as a stretched part, but can only be used for bending; the shielding bracket can be stretched, but The thickness of the bracket material must be 0.20mm and the height ≥1.25mm; 2. The minimum inner R angle at the corner of the drawing piece of the white copper shield must be at least 0.65mm, and the minimum outer R angle must be at least 1.0mm, welding method column The flanging must be above 0.20mm; 3. The width of the flange trimming around the nickel silver shielding cover is Bu003d0.2mm (1 times the material thickness), which increases the flatness stability; the inner radius of the outer frame R1 can be as small as R0.65mm , It’s better to use R1.0mm or more, the drawing can not have a sharp turn at a right angle, otherwise the drawing will break; 4. The outer corner of the outer frame R2 u003d 1.0 mm, preferably R1.5mm or more ; A size should not be less than 0.7mm, preferably 1.0mm or more. Hardware, 15 years of focus on circuit board shielding, 20,000+ sets of customized stamping mold production experience, monthly processing capacity of 100+ sets of molds, hundreds of precision processing production equipment, daily production capacity of 3 million punches, and silk-like stamping accuracy up to 0.01 mm, the raw materials are imported and the original national standard factory, and 16 quality inspections are strictly controlled.
