A Shielding Cover is a protective component used in electronic devices, primarily to prevent electromagnetic interference (EMI) from affecting sensitive circuits. It is usually made of metal materials with good conductivity, such as copper, aluminum, or nickel-plated steel, effectively blocking external electromagnetic waves while also preventing internal circuit emissions from leaking out. Shielding covers are widely used in communication devices, computers, household appliances, and Other electronic products. By enclosing or covering sensitive components, they ensure that devices can operate stably in complex electromagnetic environments, improving signal quality and system reliability. The design of shielding covers is flexible and can be customized to meet the needs of different application scenarios.
