Abstract:
1. An integrated circuit package, comprising: an integrated circuit die, the die having an active surface and a back surface substantially opposite the active surface, the active surface including a plurality of I/O pads; a lower leadframe including a plurality of lower contact leads, each lower contact lead having a first surface and a second surface substantially opposite the first surface, the first surface of each lower contact lead including at least one solder-wettable portion; an upper leadframe including a plurality of metal upper routing leads, each upper routing lead having a first surface and a second surface substantially opposite the first surface, the first surface of each upper routing lead including at least one inner solder-wettable portion and at least one outer solder-wettable portion, each inner solder-wettable portion being physically and electrically connected with an associated I/O pad by an associated solder joint, each outer solder-wettable portion being physically and electrically connected with an associated solder-wettable portion on the first surface of a lower contact lead by an associated solder joint such that each upper routing lead electrically couples an associated I/O pad with an associated lower contact lead, wherein at least most of the first surface of each upper routing lead is in direct contact with the molding material and wherein the first surface of each of the upper routing leads overlies at least most of the first surface of an associated lower contact lead.
