Circuit motherboard shielding cover, the principle of magnetic shielding effect + 15 years of experience, the manufacturer will take you to understand in three minutes

Shielding cover of circuit main board, shielding is a device method in electrical engineering. In order to prevent the interference of external electric, magnetic or electromagnetic fields on the internal equipment or to avoid the influence of the electromagnetic field of the equipment on the outside, the equipment is placed in a closed or nearly closed metal shell or metal mesh cover. For the shielding cover. In structural chemistry, the word shielding is used to name the following effects. The repulsion of the inner electrons in the atom to the outer electrons reduces the effective attraction of the outer electrons by the nucleus, which is equivalent to the inner electrons 'shielding' part of the nuclear charge, so it is called the shielding effect. The magnitude of the shielding effect between electrons can be approximately expressed by the shielding coefficient. Hardware, 15 years of focusing on circuit board shielding cover, 20,000+ sets of mold custom processing and production experience, monthly 100+ sets of mold processing capacity, daily production capacity of 3 million punches, stamping accuracy up to 0.01mm, and 16 quality inspections strictly. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve mass production quality problems. Choose, choose rest assured!
