<p><P>PROBLEM TO BE SOLVED: To provide a ball mounting mask and a method of manufacturing the same, wherein a step and a strain generated at an outer peripheral edge part of a boundary between an opening region where there is a dug recess and a no-opening region where there is not the dug recess are improved by forming many dimples (hollows) which substantially reach a depth of the dug recess in the no-opening region where there is not the dug recess. <P>SOLUTION: The ball mounting mask 3 has a screen gauze 2 stuck on a plate frame 1 by applying tension, composed of the opening region 5 where many ball insertion holes 4 into which conductive balls are inserted are formed, the no-opening region, and the dug recess formed by recessing a lower surface of the opening region, and has many dimples (hollows) 8 formed on a bottom surface side of the no-opening region of the ball mounting mask and suppressing the step and strain generated at the boundary between the opening region where there is the dug recess and the no-opening region where there is not the dug recess. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
