Abstract:
A stackable integrated circuit chip package, comprising:a flex circuit comprising: a generally rectangular, flexible substrate having opposed, generally planar top and bottom surfaces, a pair of longitudinal peripheral edge segments, and a pair of lateral peripheral edge segments; and a conductive pattern disposed on the substrate and extending along the bottom surface thereof to the longitudinal peripheral edge segments; a generally rectangular frame defining a central opening, opposed pairs of longitudinal and lateral sides, a top surface, and a bottom surface, the top and bottom surfaces of the frame being attached to the top surface of the substrate of the flex circuit; and an integrated circuit chip disposed within the opening of the frame and electrically connected to the conductive pattern; the substrate being wrapped about the longitudinal sides of the frame such that the longitudinal peripheral edge segments of the substrate extend along respective ones of the longitudinal sides of the frame and the conductive pattern defines a first portion which extends over a portion of the bottom surface of the frame and a second portion which extends over a portion of the top surface of the frame in spaced, generally parallel relation to the first portion, the first and second portions each being electrically connectable to another stackable integrated circuit chip package.
