A plurality of flipchip dies are mounted on the top leadframe strip with solder bumps of each flipchip bonded to predetermined pad portions on each of the top leadframes. The top leadframe strip is attached to a bottom leadframe strip. The bottom leadframe strip has a plurality of integrally connected bottom leadframes each having a central die attach pad (DAP) portion and a peripheral frame portion. A back face of each flipchip die contacts the DAP portion of each bottom leadframe. Lead portions of each top leadframe are attached to the peripheral frame portion of each bottom leadframe. The top leadframe strip is attached to the bottom leadframe strip with a back face of each flipchip die contacting the DAP portion of each bottom leadframe and with lead portions of each top leadframe attached to the peripheral frame portion of each bottom leadframe.

Abstract: A method includes forming a leadframe assembly to have a pair of opposing sides, and having semiconductor die receiving portions extending between the opposing sides. The method also includes placing semiconductor dies on the leadframe assembly in the die receiving portions. Each die has a row of leads on each of two opposing sides of the die and a longitudinal axis parallel to the rows of leads. The longitudinal axis of each die is orthogonal to the opposing sides of the leadframe assembly. The method further includes applying mold compound to the semiconductor dies. The method includes punching through the leadframe assembly between the opposing sides using a first tool having a first tool longitudinal axis parallel to longitudinal axes of the dies.
