Abstract:
1. A method of making an exposed-pad ball-grid array (BGA) package comprising: applying a conductive sheet to an adhesive tape; forming a die pad from the conductive sheet by stamping a portion of the conductive sheet and removing a remainder of the conductive sheet, wherein the stamped portion of the conductive sheet defines the die pad; applying a substrate to the adhesive tape proximate to the die pad; attaching a semiconductor die to the die pad; electrically coupling the die to a top surface of the substrate; encapsulating at least a portion of the die, the die pad and the substrate with an encapsulant above the adhesive tape; removing the adhesive tape from the die pad, substrate and encapsulant; and attaching at least one conductive ball to a bottom surface of the substrate.
