Abstract
A method of soldering a component on a printed circuit board which has the steps of sucking the components supplied in an irregularly aligned disposition by a feeding sucking nozzle tube, then holding the components by a pair of holding arms of a soldering iron from right and left sides to always direct the component in a predetermined direction, placing the components at predetermined positions on a printed circuit board as in this state, melting the preliminary solder placed in advance on the board, air-cooling to solidify the solder to solder a number of components with a short time by always obtaining the desired designating direction so as not to displace the positions and to locally heat the chip components. Thus, this method can delete thermal adverse influence to the component and obviate an unintentional drop of chip components during the step of feeding the components.
