1. An alignment-assisting tray comprising a plurality of concave cells for storing a plurality of minute elements, respectively and individually, each of the plurality of minute elements has quadruple flat side planes, in which adjacent side planes of the quadruple flat side planes intersect each other at a right angle,
wherein the plurality of concave cells are arrayed in accordance with a layout of locations where the plurality of elements are scheduled to be mounted on a mounting board, respectively,
a space is provided in each of the plurality of concave cells for installing each of the plurality of minute elements, such that each of the plurality of minute elements is surrounded by quadruple sidewall-planes of each of the plurality of concave cells, each of quadruple sidewall-planes is prepared to be mated with a counterpart side surface in one of a corresponding element among the plurality of minute elements, and
each of the diagonal lengths of the plurality of concave cells viewed on a planar pattern is longer by 50 percent or more than 50 percent of a diagonal length of each of the plurality of minute elements in a corresponding direction of the diagonal lengths of the plurality of concave cells, and
a set of the flat side planes adjacent to each other implements a moving ridge-to-be-mated in each of the plurality of minute elements, respectively, the moving ridge-to-be-mated is a convex-ridge closest to a counterpart interfacing ridge, the counterpart interfacing ridge is implemented by a specific set of the adjacent quadruple sidewall-planes, the moving ridge-to-be-mated is elected among quadruple convex-ridges in each of the plurality of minute elements, and each of the moving ridge-to-be-mated is scheduled to be moved toward the counterpart interfacing ridge.
