Key points of shielding isolation cover design

Shielding is the metal isolation between two space areas to control the induction and radiation of electric field, magnetic field and electromagnetic wave from one area to another. Specifically, shielding is used to surround the interference sources of components, circuits, assemblies, cables or the whole system to prevent the interference electromagnetic field from spreading outward; shielding is used to surround the receiving circuits, equipment or systems to prevent them from being affected by the external electromagnetic field. Because the shielding body has the functions of absorbing energy (eddy current loss), reflecting energy (interface reflection of electromagnetic wave on the shielding body) and counteracting energy (electromagnetic induction generates reverse electromagnetic field on the shielding layer, which can counteract part of interference electromagnetic wave) to the external interference electromagnetic wave and internal electromagnetic wave from wires, cables, components, circuits or systems, etc The function of reducing interference. （
