<p>A support base (12) supports a double-sided mounting printed circuit board (66) by a horizontal surface (13). A rear side electronic part (65b) is disposed in a window hole (14). A first heating unit (15) heats an electronic part (65a) on the front side of the printed circuit board (66) from the front side of the printed circuit board (66). A second heating unit (16) heats the electronic part (65b) on the rear side of the printed circuit board (66) from the rear side of the printed circuit board (66). The electronic parts (65a, 65b) can be simultaneously removed from the front and rear sides of the printed circuit board (66). The working time can be remarkably reduced as compared with the case where the electronic parts are sequentially removed from the front and rear surfaces.</p> |
