Abstract
An apparatus for fixing electronic parts to a printed circuit board is disclosed which comprises a vapor generating tank or boiling and generating a thermal medium and a returning tank for receiving the thermal medium containing flux. The vapor generating tank and the returning tank are separated from each other. By utilizing the level difference between the vapor generating tank and the returning tank, the thermal medium is charged into a flux separator and discharged therefrom. Thus, the mixture of the flux into the thermal medium may be reduced and its maintenance work may readily be carried out, thereby reducing a running cost of the apparatus.
