Patent ID: 7569939

Claim:
An electronic assembly comprising: a substrate; a die; a plurality of alignment bumps on one of the die and the substrate; a plurality of groups of mating bumps on the other of the die and the substrate, the plurality of groups of mating bumps being positioned such that if each alignment bump engages each mating bump in each respective group of mating bumps, the die is appropriately positioned relative to the substrate; a plurality of solder contact bumps that extend from the die; and a plurality of solder contact bumps that extend from the substrate to engage the plurality of solder contact bumps that extend from the die, wherein the solder contact bumps extend from the respective substrate and die to engage one another without engaging the plurality of alignment bumps and the plurality of groups of mating bumps, wherein both the die and the substrate each include at least one group of mating bumps and at least one alignment bump, wherein each of the solder contact bumps on the substrate engages only one solder contact bump on the die.
