PROBLEM TO BE SOLVED: To provide a method and device which can prevent deterioration of reliability on a soldered bond due to occurrence of a stringing phenomenon and can achieve accurate feeding of a proper amount of solder, when a soldering is performed with a string solder. SOLUTION: Using solder balls 11 as a solder material, they are filled in line inside a tubular member 12, picked up by a designated amount using members 13, 14 for controlling transfer of solder balls inside the tubular member and then discharged outside the tubular member. Discharged solder balls are heated and melted by a solder iron or the like and used for soldering. When solder balls are discharged, flux can be concurrently discharged together with solder balls so that corrosive action of the flux to the solder can be reduced. COPYRIGHT: (C)2005,JPO&NCIPI
