PURPOSE:To improve the quality of the bonding by performing a scrubbing of an adsorption nozzle in a desired direction driven by drive motors set in X and Y axes so as to select a bonding part in the optimum direction and evenly spread the bonding layer. CONSTITUTION:An adsorption nozzle 1 is moved within a slight range while a die 16a is pressed fit on a lead frame. Here, positive or opposite pulse is applied selectively on drive motors set in X and Y axes, it can perform various scrubbing motions. The scrubbing of the nozzle in the optimum direction makes the spreading of a solder, an epoxy adhesive or the like evenly for bonding thereby improving the quality. |
