Abstract:
Methods, systems, and apparatuses for integrated circuit packages, such as ball grid array packages, and processes for assembling the same, are provided. A first strip includes an array of package substrate sections. An IC die is mounted to each package substrate section of the first strip. A second strip includes an array of leadframe sections. The second strip is positioned adjacent to the first strip to couple a planar protruding area of each leadframe section to a corresponding IC die mounted to the first strip. An encapsulating material is applied to the adjacently positioned first and second strips to fill a space between the first and second strips and to fill a cavity in a top surface of each leadframe section. A planar region of the first strip surrounding each centrally located cavity is not covered by the encapsulating material. The adjacently positioned first and second strips are singulated into a plurality of IC packages.
