With a remarkable portfolio of nine patents, Li Sun has made significant contributions to the field, particularly in electromagnetic shielding and substrate design.

Latest Patents

Li Sun's recent inventions showcase his ingenuity and technical expertise. One of his notable patents is the "Package with Self Shielding." This innovation addresses the challenge of preventing electromagnetic fields from leaking outside a module by emulating an electric wall using through vias arranged around cavities in printed circuit boards. By thoughtfully selecting the density of these vias based on the expected wavelengths of electromagnetic fields, Li's design effectively self-isolates components within the cavities from interference.

Another groundbreaking patent from Li is the "Substrate Having Undercut Portion for Stress Mitigation." This device features a substrate with two opposing surfaces and a solder material-receiving curved surface exposed at the second surface. The design includes a solder resist material that partially covers this curved surface, creating an undercut that aids in stress mitigation. This clever arrangement ensures that the solder material is securely held within the designated area, enhancing the overall performance of electronic devices.
