Circuit motherboard shielding cover, 15 years of design and production of the shielding cover + stamping accuracy of 0.01mm

The hardware technicians of the circuit motherboard shielding cover manufacturer said that the nickel silver 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? 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 It needs to be 0.20mm, height ≥1.25mm; 2. The small inner R angle at the corner of the nickel silver shielding cover tensile part must be at least 0.65mm, and the smaller outer R angle must be at least 1.0mm, and the welding method should be turned over The edge must be above 0.20mm; 3. The width of the flange trimming around the white copper shielding cover is Bu003d0.2mm (1 times the thickness of the material) to increase the flatness stability; the inner round corner R1 of the outer frame can be R0.65mm , 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; A size is not required It is less than 0.7mm, preferably 1.0mm or more. Hardware, 15 years of focus on circuit board shielding, 20,000+ sets of customized stamping die 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.
