<p>PROBLEM TO BE SOLVED: To provide a method and an apparatus with which an irradiating treatment can be applied for a short time, in a light beam soldering method and a light beam soldering apparatus irradiating a plurality of cream solders (S) coated on a base material (W) to be treated. SOLUTION: In the irradiation of the plurality of cream solders (S) coated on the base material (W) to be treated, the converged light beam irradiating from a light beam irradiating part (1), is introduced into a cylindrical member (3) having a reflecting characteristic in the inner surface. This irradiating treatment is peculiarly applied by setting the above cylindrical member (3) to the opening part and the length, with which the irradiating treatment can be applied at a position widened into such optimum range so as to collectively irradiate the plurality of cream solders (S) on the base material (W) to be treated after converging the irradiating light beam from this light beam irradiating part (1) at least at once.</p> |
