Patent ID: 8525312

Claim:
A microelectronic assembly, comprising: a lead frame including a first unit and a second unit overlying the first unit and assembled therewith, the first unit having a first metal layer comprising a portion of the thickness of the lead frame and including terminals and first conductive elements extending away therefrom, the first unit having a first encapsulation supporting at least portions of the first conductive elements, the terminals exposed at a surface of the first encapsulant and configured for connection with a component external to the microelectronic assembly, the second unit having a second metal layer comprising a portion of the thickness of the lead frame and including bond pads and second conductive elements extending away therefrom, the second unit having a second encapsulation supporting at least portions of the second conductive elements, at least some of the second conductive elements overlying portions of corresponding ones of the first conductive elements and being joined thereto; and a microelectronic element having contacts electrically connected with at least some of the bond pads of the lead frame, the microelectronic element overlying a die attachment pad portion of the second metal layer, the die attachment pad portion overlying at least some of the terminals, the die attachment pad portions being electrically insulated from the terminals by the first and second encapsulations.
