Patent ID: 7866534

Claim:
A conductive ball mounting method of mounting one conductive ball on each of a plurality of pads coated with an adhesive flux on a substrate, the conductive ball mounting method comprising: (a) disposing a conductive ball mounting mask over the substrate such that the conductive ball mounting mask is opposed to the substrate, wherein the conductive ball mounting mask includes a plurality of ball mounting through holes for mounting each of conductive balls on each of the plurality of pads and a plurality of air vent portions spaced from and between the plurality of ball mounting through holes to allow air to ventilate through the conductive ball mounting mask, the vent air portions being sized so as to prevent conductive balls from passing therethrough; (b) supplying the plurality of conductive balls on the conductive ball mounting mask; and (c) moving or removing the plurality of conductive balls on the conductive ball mounting mask by sucking an air on an upper surface side of the conductive ball.
