Abstract:
1. An electronic package, comprising: a support plate; at least one integrated circuit chip supported by said support plate; a plurality of electrical connection pads mounted to the support plate and electrically connected to the at least one integrated circuit chip; an encapsulation block encapsulating the at least one integrated circuit chip and the plurality of electrical connection pads and covering an upper surface of the at least one integrated circuit chip and respective upper surfaces of the plurality of electrical connection pads, the encapsulation block defining a first peripheral edge and a second peripheral edge opposite the first peripheral edge; and at least one weakening deep groove formed in the encapsulation block and extending to a short distance directly above the at least one integrated circuit chip and extending from the first peripheral edge to the second peripheral edge, said at least one weakening deep groove configured to reduce a resistance of the electronic package to bending stresses perpendicular to the support plate.
