Shield can mounting clip design for robust and enhanced shielding effectiveness in mobile devices

A small metallic shield enclosure, commonly called a shield can, is an indispensable component of modern mobile devices in reducing electromagnetic interference. A sophisticated clip design utilising an embossing technique and a furrow structure for mounting shield cans on printed circuit boards in mobile devices is proposed in order to enhance the robustness and effectiveness of the shield cans. The proposed design is validated by radiated spurious emission measurement and three-dimensional field simulation.
