Abstract:
1. A package structure inspection method, comprising the steps of: a) providing a package structure, said package structure comprising a substrate, at least one chip module mounted on said substrate, a molding compound covering said at least one chip module and one surface of said substrate, and a conductive shielding layer covering said molding compound and at least a part of lateral edges of said substrate, said substrate comprising a plurality of inner grounding structures electrically connected to one another and at least one independent conducting structure exposed to the outside of said substrate, said at least one independent conducting structure and a predetermined number of said inner grounding structures being electrically connected with said conductive shielding layer; and b) measuring the resistance value between said at least one independent conducting structure and said conductive shielding layer and then comparing the measured resistance value with a predetermined reference value.
