Abstract:
A solder-removing apparatus for removing solder from an object, comprising:a heating portion for heating the object having the solder adhered thereto; a measuring portion for measuring the distance from said measuring portion to at least two points of the object; a solder-drawing portion for drawing the molten solder on the object by suction; an X-Y moving portion for moving the object in an X-direction or a Y-direction; a Z moving portion for moving the object relative to said solder-drawing portion in a Z-direction; and a control portion for controlling said X-Y moving portion and said Z moving portion; wherein said control portion obtains displacement of the object in accordance with measured results during the time when the molten solder on the object is drawn by said solder-drawing portion, said control portion causes said X-Y moving portion to move the object, and also causes said Z moving portion to move the object relative to said solder-drawing portion in accordance with said obtained displacement, so that the distance between said solder-drawing portion and the object can be kept constant.
