Abstract:
A package-on-package arrangement for maintaining die alignment during a reflow operation is provided. A first top die has a first arrangement of solder bumps. A bottom package has a first electrical arrangement to electrically connect to the first arrangement of solder bumps. A die carrier has a plurality of mounting regions defined on its bottom surface, wherein the first top die is adhered to the die carrier at a first of the plurality of mounting regions. One of a second top die and a dummy die having a second arrangement of solder bumps is also fixed to the die carrier at a second of the plurality of mounting regions of the die carrier. The first and second arrangements of solder bumps are symmetric to one another, therein balancing a surface tension during a reflow operation, and generally fixing an orientation of the die carrier with respect to the bottom package.
