Chip shield manufacturer, design knowledge of shielding cover + silk-like stamping accuracy can reach 0.01mm

Chip shield manufacturers, mobile phones, transformers, routers and other products, choose nickel-nickel copper shields, its function, design, and installation, all have some experience summarized by engineers. So what experience have been summed up? Let me know about it with you: 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 bracket material is thick Must be 0.20mm, height ≥1.25mm; 2. The minimum inner R angle at the corner of the nickel-nickel copper shield tensile part must be at least 0.65mm, the minimum outer R angle must be at least 1.0mm, and the welding method must be flanged Above 0.20mm; 3. The cutting edge width of the flanges around the white copper shielding cover is Bu003d0.2mm (1 times the material thickness), which increases the flatness stability; the inner round corner R1 of the outer frame can be as small as R0.65mm, the best R1.0mm or more is better, the drawing forming can not 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 Not less than 0.7mm, preferably 1.0mm or more. Hardware, 15 years of focus on chip shield manufacturers, 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.
