Abstract:
1. An electronic assembly comprising: a substrate that includes a plurality of contact bumps; a die that includes a plurality of contact bumps which engages the plurality of contact bumps on the substrate; an alignment bump on one of the die and the substrate; and a group of mating bumps on the other of the die and the substrate, the group of mating bumps being positioned such that if the alignment bump engages each mating bump in the group of mating bumps, the die is appropriately positioned relative to the substrate where the alignment bump engages the mating bumps, wherein the alignment bump is higher than the plurality of contact bumps such that the alignment bump engages at least one of the mating bumps before the plurality of contact bumps on the substrate engages the plurality of contact bumps on the die.
