20130257462 | PACKAGE STRUCTURE WITH CONFORMAL SHIELDING AND INSPECTION METHOD USING THE SAME - A package structure with conformal shielding includes a substrate providing electrically connected inner grounding structures, a chip module mounted on the substrate, a molding compound covering the chip module and one surface of the substrate, and a conductive shielding layer covering the molding compound and the lateral sides of the substrate, and electrically connected with a part of the inner grounding structures. The substrate further provides one or multiple independent conductive structures electrically connected with the conductive shielding layer and exposed to the outside. By measuring the resistance value between one independent conductive structure and the conductive shielding layer or another independent conductive structure or one ground contact and then comparing the measured resistance value with a predetermined reference value, the EMI shielding performance of the package structure is determined. | 2013-10-03 |
