The Electronic Equipment Shielding case is an essential component in electronic systems, primarily used to block electromagnetic interference, prevent internal electromagnetic signal leakage, and effectively resist external electromagnetic disturbances that could affect device performance. By protecting circuit boards and key components, the Shielding Case enhances the device's anti-interference capability and electromagnetic compatibility (EMC) performance, ensuring stable signal transmission and improving the overall reliability and safety of the system. As electronic products become increasingly sophisticated, shielding cases play an increasingly important role in fields such as communication equipment, medical devices, automotive electronics, and industrial control, becoming a key protective measure to ensure stable device operation and extend service life.
