ABSTRACT:
A mounting head is composed of a box-shaped main body, a case contained inside the main body, and a suction tool in the lower part of the case. The main body and case are coupled by a spring member, and the weight of the suction tool is canceled by the force of the spring. A cylinder is provided in the main body, and a rod is coupled to the case and cylinder. Solder balls sucked in by a vacuum into suction holes of the suction tool are pressed onto the electrodes of a workpiece by the cylinder. The mounting head is moved up and down by elevating means comprising a ball screw, a nut, and a motor. The pressing force of the suction tool by the cylinder is set to a proper magnitude so that the solder balls are not squeezed or crushed into the electrodes or sink into the suction holes of the suction tool.
