Patent ID: 8093694

Claim:
A method of manufacture of a non-leaded integrated circuit package system comprising: etching differential height lead structures to form inner leads and outer leads, the outer leads comprising bottom outer lead surfaces and a reduced height extension, the reduced height extension having a height less than that of the outer lead, and the differential height lead structures having different heights with transition points between the inner leads and the outer leads, having the inner leads at a paddle height; providing mold locks at the transition points of the differential height lead structures; etching an elevated paddle at a same height as the inner leads; mounting a first integrated circuit on the elevated paddle; electrically connecting first electrical interconnects between the first integrated circuit and the inner leads; and applying a molding compound with the mold locks within the molding compound for exposing the bottom outer surfaces of the lead structures and the reduced height extension protruding from a side of the molding compound and extending along the bottom outer lead surfaces.
