PURPOSE:To perform efficiently soldering of fine solder lands by providing a means for pressing parts to the soldering positions, providing a light transmission path to the pressing means and enabling elastic deformation in the pressing direction. CONSTITUTION:Preliminary solder 5 is formed to plural soldering lands 2, 4 on a hard substrate 1 and/or flexible substrate 3 and a pressing plate 8 which can be positioned in X-, Y- and Z-directions respectively according to the amt. of such preliminary solder is pressed to the substrate 3 from above the same. The plate 8 is constituted of glass fibers 9 allowing transmission of laser light and silicone rubber matrix 10 enclosing the same. The substrate 1 and the substrate 3 are pressed and positioned by the plate 8 and laser light 7 is irradiated via the fibers 9 to spot-heat successively the solder 5, thus soldering the substrates. The sure soldering is thus performed irrespectively of the amt. of the preliminary solder. |
