Abstract:
1. An electronic assembly comprising: a first layer having a first interface surface and a plurality of cavities formed in the first interface surface; a second layer having a second interface surface and a plurality of electrically conductive projections disposed at the second interface surface, wherein the plurality of projections are aligned with and disposed at the plurality of cavities, the second layer comprising a diode array having a plurality of backlit photodiodes in electrical communication with the plurality of projections; and an electrically conductive connecting material disposed at the plurality of cavities such that the connecting material non-separably connects the plurality of projections to the respective plurality of cavities, each of the plurality of cavities being configured to constrain the connecting material disposed thereat from outward flow; wherein the plurality of cavities are formed having a depth d in the first interface surface; wherein the first interface surface is disposed apart from the second interface surface by a gap g; and wherein the plurality of projections have a length h that is equal to or less than the sum of the depth d and the gap g, such that the connecting material bridges the distance defined by (d+g−h).
