A machine and a method for attaching solder balls are provided to quickly and easily replace a solder ball cartridge according to various patterns of a substrate or wafer, thereby accurately seating the solder balls on an altered pattern. A first clamp(110) pneumatically holds a flux cartridge(40) having protruding pins corresponding to a pattern formed on a substrate or a wafer. A first transfer unit transfers the first clamp so that flux is adhered on the pins of the flux cartridge and then is adhered on the pattern. After a solder ball cartridge holds the solder balls, a second transfer unit transfers the solder balls onto the pattern. The first clamp has a first clamp body integrally secured to the first transfer unit and a grip block moved by a guide bar inserted in the first clamp body.
