PURPOSE:To perform automatically soldering without giving any trouble to electric parts and to improve the working property, by installing a through-hole in the support of insulating substrate and a means which moves the substrate to a preheated soldering position through the through-hole. CONSTITUTION:An insulating substrate 26 equipped with terminals 27a and 28a of electric parts 27 and 28 is put in the recessed part 22 of a support 20. The support is placed on rails 4 and a groove 24 at the lower surface of the support 20 is faced to a preheating heater 11 and the soldering part at the lower surface of the substrate 26 is preheated through a through-hole 25 formed in the groove 24. Then, the support 20 is transferred by using a transferring plate 10 and the groove 24 is allowed to correspond to an ejecting hole 17 installed in a solder tub 13. The molten solder 18 ejected from the ejecting hole 17 is controlled by the groove 24 and contacts the terminal 27a (28a) at the lower surface of the substrate 26 through the through-hole 25 formed in the groove 24, and thus, the soldering is performed. |
