Title: Forming method for solder layer and solder supply device used therefor
Inventor: TAKAHATA KAZUMI
IPC: H01L21/58
Filed: 1984-02-27
Abstract: PURPOSE:To preferably form a solder layer by supplying solder having high cleaning degree by discharging the solder from the portion except the upper surface portion of the melted solder in a solder tank, thereby obtaining preferable wettability even in case of no flux. CONSTITUTION:A substrate 11 is moved by a feeder 12 underneath a solder supply device 13, and heated by a heater 18 to approx. 350 deg.C. N2 gas is supplied to the heating space in the heater 18 by a gas supply device 19 to form sufficient nonoxidative atmosphere. The melted solder 14 of a tank 21 is pressed to the prescribed pressure and prescribed time pulse in the prescribed synchronous relation to the feeder 12 by N2 gas fed from the pressing unit 24 of a solder agitator 15. The prescribed amount of melted solder 14 is discharged from a nozzle 20 only when the solder 14 is pressed by the unit 24 in a pulse manner. After the solder 14a is completely supplied, the substrate 11 is fed underneath the solder agitator 15, and a film solder 14b is formed by an agitating head 28. Thus, since the nonoxidative atmosphere and the heated state of 350 deg.C are held, the melted solder film layer 14b can be formed in good wettability on the substrate 11.
