PURPOSE:To reduce a vibration at the time of carrying, and to improve the accuracy of solder brazing by using a liquid for carrying a parts assembly body. CONSTITUTION:A soldering equipment is constituted of a heating chamber 11 which has been covered with a cover 8, and a vessel part 7 for containing a high boiling point liquid 4 such as fluorocarbon, etc. The vessel part 7 is extended long in the carrying direction 9 of an assembly body 10 consisting of a substrate to be worked 1 and electronic parts 2, and carried into the heating chamber 11 by pre-heating the assembly body 10 together with a float 3 by using a liquid surface of the liquid 4. In this regard, a heater 5 is installed in the heating chamber 11 and in the liquid 4. According to this reflow soldering equipment, the positioning accuracy can be lowesed by vibration, therefore, the electronic parts, etc., can be soldered precisely. |
