Abstract: PURPOSE: A solder ball manufacturing apparatus is provided to improve a precision and productivity. CONSTITUTION: An apparatus includes a melting furnace(101), a nozzle(104), a vibrator(103), and a size inspector. The solder melted in the furnace is flowed to the nozzle through a pipe(102). A signal generator(109) generates the frequency of 100-5,000 Hz according the solder ball size. The signal amplified in an amplifier(110) is supplied to the vibrator which vibrates the nozzle with the applied signal. In a time, the speed of the melted solder is varied according the applied vibration, so a surface wave which frequency is same to the applied one is formed on surface of melted solder(106) left just from the nozzle. The surface wave is amplified more as far as from the nozzle and the melted solder is turned to the solder ball.
