METHOD AND DEVICE FOR REFLOW TYPE SOLDERING AND METHOD AND DEVICE FOR CLEANING HEATING TIP FOR REFLOW TYPE SOLDERING

摘要

PURPOSE:To improve the quality of soldering and to shorten the time for soldering by parting a heating tip from a soldering part in accordance with the degree of the penetration of solder and further cleaning the surface thereof in accordance with the degree of contamination on the tip surface. CONSTITUTION:A welding head 1 disposed with the heating tip 2 is provided above the soldering part on a working table 6 and a displacement means 7 for displacing the tip 2 in a vertical direction is disposed. The position of the tip 2 is detected by a detector 902 when the tip 2 descends upon melting of the solder 3. Then, a displacement driving control means 8 drives a motor 702 to part the tip 2 from the solder 3 in accordance with the penetration amt. of the solder 3. Further, a tip cleaning means 14 cleans the tip 2 to get rid of the contaminations in accordance with the excess of the heating time. The overheating of the soldered part is prevented by parting of the tip 2 and since the tip 2 is maintained always in the clean state, the quality of soldering is improved and the required time is shortened.
