Abstract: PURPOSE:To realize the automatic soldering (binding of a supporting member  and a vibrating bar), by supplying the paste solder on the upper surface of an  airtight terminal set to a carrier after setting a vibrating bar to a tool and then applying hot air to the tool and the carrier which are set together to eliminate the soldering process to the vibrating bar and the supporting member. CONSTITUTION:An airtight terminal 4 is set to a tool A, and then a vibrating bar 1 is set to a vibrating bar setting tool B. Then the paste solder is supplied to the upper surface of the set airtight terminal. A carrier with which the above- mentioned processes are through is set to the tool A. The bar 1 set to the toolslides down between two supporting members and set on the stuck paste solder. Under such conditions, the hot air is blown to the area of the paste solder. Thus the solder is melted to stick to the electrodes formed to the supporting member and the bar 1 owing to the surface tension and the wetting property of the solder, and the solder between two supporting members is separated. As a result, a complete oscillator has no short circuit although the paste solder was first supplied over the two supporting members.
