Abstract: A parallel link robot (10) allows holding a movable body (13) in midair by connecting a center portion or a peripheral portion of the movable body (13) and a center portion or a peripheral portion of a base (12), using a suspension unit (17) having elasticity such as a constant load spring.

Abstract: A paste applicator and paste application method for die bonding apply paste to adhere a semiconductor chip on a substrate. Data on paste application volume and application pattern which can be identified from paste thickness and chip size are stored. A dispensing flow rate calculator calculates dispensing flow rate of a dispenser based on the paste application volume data and application pattern data when the paste is dispensed from the dispenser and pressure fed to an application nozzle for applying paste. Based on this calculated dispensing flow rate and application pattern data, a dispenser controller controls the dispenser and a transfer table controller controls the transfer table for moving the application nozzle.

Abstract: The object of the present invention is to provide a bonding paste applicator and a method of applying a bonding paste which allow satisfactory paste applying quality and excellent operability to be realized. A bonding paste application method for applying a bonding paste by making a drawing with a paste applying nozzle made to move to a position, where a chip is mounted on a substrate, comprises the steps of storing in advance in a storing unit 46 a drawing pattern for controlling each of X, Y and Z axes to move a paste applying nozzle and a drawing pattern setting table 53 to show a category corresponding to the size of a chip to be bonded, selecting a drawing pattern corresponding to the size of the chip, which has been designated, by means of a drawing pattern selecting unit 54 and obtaining a speed pattern for each of the X, Y and Z axes based on the selected drawing pattern by means of a speed pattern computing unit 55.

Abstract: A method of applying a bonding paste efficiently and uniformly by discharging the bonding paste from an application nozzle is presented. For applying the paste along a drawing pattern including a cross shape pattern composed of crossing plural application lines, the nozzle moves from the center of the cross shape to an end point along one application line, turns to a reverse direction at the end point, and moves to an end point at opposite side of the application line. Then, the nozzle returns from the end point to the center of the cross shape. The nozzle repeats this unit application line drawing operation for each application line. As a result, the nozzle stops less frequently near the center, has a shortened cycle time, and applies the paste uniformly.

Abstract: In a paste applying method for applying paste in an application area set on the surface of the object to be applied, the application efficiency is enhanced and the application quality is improved by applying the paste in an undulation pattern of convex and concave shape that defines the interior of the surface of the object on which no paste is deposited, where the interior area is substantially enclosed by the undulation pattern of the paste. A discharge port of an application nozzle is moved with one continuous line from an application start point to an application end point along the moving route by a plurality of passing points. The plurality of passing points are set at each comer of the application area and include a plurality of first passing points and a plurality of second passing points, where the first passing points are set at each corner of the application area and the second passing points are set at the central side of the application area.
