AI Technical Summary

Technical Problem

As the integration of electronic devices increases, electromagnetic interference problems in electronic devices are becoming increasingly serious. Existing shielding structures are difficult to effectively shield low-frequency electromagnetic interference and occupy additional planar design space, affecting the reliability and miniaturization of equipment.

Method used

Introducing at least one second shielding layer into electronic devices, set within the first shielding layer, and forming a small shielding cavity through multiple sub-layers, combined with highly conductive and high-loss materials, enhances the electromagnetic shielding effect while avoiding occupying additional planar design space.

Benefits of technology

It improves the shielding effect of electronic devices against electromagnetic interference, especially low-frequency interference, enhances the reliability and flexibility of the devices, and supports the miniaturization design of the devices.
