Abstract:
1. An electronic assembly, comprising: a first element having a first surface; a second element having a second surface; electrical connections between the first and the second elements formed by heating solder bumps; and a plurality of collapse limiter structures coupled to at least one of the first and the second surfaces, wherein the plurality of collapse limiter structures are dispersed in an array of the electrical connections, wherein the array includes at least three electrical connections in a first direction and at least four electrical connections in a second direction, and wherein in the array, a plurality of the collapse limiter structures are positioned between different pairs of electrical connections in the first direction and the second direction wherein a length of the collapse limiter structures dispersed in the array between different pairs of electrical connections is less than a height of the electrical connections attached to the first surface before the heating operation.
