    摘要: A soldering machine using lead-free solders is provided which can uniformly heat a printed circuit board and electronic parts to be mounted thereon, and which can solder the electronic parts without thermally damaging them. A porous member having a number of holes formed therein is disposed between a blower fan and a heater for making uniform the pressure of a fluid. A radiation plate is disposed between the heater and a heating target for blowing the fluid having been heated by the heater to the heating target in the form of a turbulent flow. The heated fluid is blown to the heating target for heating the same, whereby solder is melted.

    摘要: A mask 11 has a plurality of holes formed at positions corresponding to positions of a plurality of electrode portions 10a on one surface of an object to be processed 10 to mount thereon conductive particles 13, and the plurality of holes are opposite to the plurality of electrode portions 10a formed on the object to be processed. A table 12 has a plurality of holes 12a for sucking the object to be processed 10 from the other surface of the object to be processed 10, and for sucking the particles 13 through the plurality of holes 11a in the mask 11 so that the particles 13 may be mounted on the electrode portions 10a formed on the object to be processed 10. A hopper 14 contains therein the plurality of conductive particles 13, prevents the plurality of conductive particles 13 from adhering to each other, and has a slit portion 17 for dropping the plurality of conductive particles 13 by the self-weight. A slit portion 17 in the hopper 14 is moved, facing the upper surface of the mask 11 with a gap between the slit portion 17 and the upper surface of the mask 11 larger than a diameter of the particle 13, and the hopper 14 is arranged in the front side in the moving direction, and the unit 15 is arranged in the rear side, and the particles 13 not dropped into the holes of the mask being collected by the collecting unit 15.

    摘要: This invention provides a soldering method capable of solving soldering defects due to excess molten solder in the case of soldering while applying an inner pressure into a through-hole of a lead component mounting substrate: (a) In a primary soldering step, a lead component mounting substrate is lowered, and the rear surface thereof is put close to or brought into close contact with an upper end opening edge of a nozzle. Simultaneously, the soldering surface of the molten solder supplied to the nozzle is elevated. (b) In a secondary soldering step, the rear surface of the lead component mounting substrate is relatively spaced from the soldering surface of molten solder by lowering the soldering surface. (c) In a lead separating step, the lead component mounting substrate is elevated while tilting the lead component mounting substrate.
