<p><P>PROBLEM TO BE SOLVED: To provide a mask and an arranging method for mounting micro-balls surely on a work in a specified array pattern. <P>SOLUTION: In order to mount micro-balls on one side of a work in a specified array pattern, the mask has one side being fed with the micro-balls and the other side opposing the one side, and through holes opening to the one side and the other side in correspondence with the array pattern and capable of inserting the micro-balls, wherein the other side is positioned at one side of the work and the micro-balls are passed through the through holes and mounted on one side of the work. When the other side is positioned at one side of the work, following relation is satisfied 0.8≤t/d≤1.4 between the distance t from one side of the work to one side of the mask and the diameter d of the micro-ball. The through hole has a first tapered part spreading from one side toward the other side and the ridge line at the side edge of the first tapered part on one side is shifted to the one side from the center of the micro-ball mounted on one side of the work. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
