Abstract:
1. A multi-chip module (MCM), comprising: a first substrate having a first surface and a second surface on an opposite side of the first substrate from the first surface, wherein a set of first coupling elements are disposed on the first surface, wherein each first coupling element comprises a layer with a first reflow characteristic, and wherein the set of first coupling elements are configured to mechanically couple the first substrate to another component; and a second substrate having a third surface that is mechanically coupled to one of the first surface and the second surface by a set of second coupling elements, wherein each second coupling element comprises a layer with a second reflow characteristic, and wherein the first reflow characteristic is different than the second reflow characteristic, wherein each coupling element in the set of first coupling elements comprises a positive feature and a negative feature, wherein the negative feature of the coupling element in the set of first coupling elements defines an opening on the first surface of the first substrate and wherein the positive feature of the coupling element in the set of first coupling elements is coupled to the negative feature inside the opening and protrudes from the first surface, wherein a set of first proximity connectors are disposed on one of the first surface and the second surface, wherein a set of second proximity connectors are disposed on the third surface, and wherein the set of second coupling elements align the first proximity connectors and the second proximity connectors, and assemble the MCM, thereby facilitating proximity communication between the first substrate and the second substrate.
