Abstract
An apparatus for mounting solder balls comprises a stage to support a substrate thereon, a mounting unit to mount solder balls on the substrate, and a solder ball mask between the mounting unit and the substrate. The solder ball mask includes a first face facing the substrate and a second face opposite to the first face. The solder ball mask has inner surfaces defining through-holes extending through a thickness of the solder ball mask from the second face to the first face. The apparatus causes the solder balls to move through separate, respective through-holes. Each of the through-holes includes a first opening defined in the first face and a second opening defined in the second face. A first spacing between adjacent first openings of the plurality of through-holes is different from a second spacing between adjacent second openings of the through-holes.
