Abstract:
A system for precision self-alignment of multiple modules, comprising:at least one alignment substrate including at least one mounting surface and a plurality of self-alignment features having a first profile formed along a first crystalline plane of the mounting surface; and a plurality of module substrates, each module substrate including a base surface and an alignment key having a second profile formed along a second crystalline plane of the base surface, the second profile complements the first profile and the first and second crystalline planes are identical to each other, the module substrates are connected with the alignment substrate by inserting their respective alignment keys into a selected one of the self-alignment features so that the alignment keys and the self-alignment features are connected in mating engagement with each other, and wherein the module substrates are positioned in near perfect self-alignment with one another with substantially no skew in a X-Y plane, a X-Z plane, and a Y-Z plane of a coordinate system.
