    摘要: A solder-ball-supplying method, a solder-ball-supplying device and a solder-bump-forming method, which are flux-less and capable of being also applied to electrodes having a fine pitch. A substrate on which a resist with openings is positioned on electrode(s), which has a diameter of 10 through 30 μm, of the substrate is prepared. Next, plural solder balls SBL each having a grain diameter of 1 through 10 μm are shaken down to the opening(s) of the resist from a hopper and filled therein. Next, by sliding and moving a squeegee on an upper surface of the resist along X-Y direction, the solder balls SBL shaken down to the resist other than the openings are scrapped and removed and the solder balls SBL in the openings and around them are pushed into the openings by the squeegee.
