A bonding tool cooling apparatus () provided in the vicinity of a bonding stage, including a frame (); a cooling member () including a ground plate () having a ground surface () on which a front edge surface of a bonding tool () is grounded, and a heat radiation fin () attached to an opposite surface of the ground plate () to the ground surface (), wherein the cooling member () is supported on the frame () by a support mechanism () so that the cooling member () is rotatable about two axes, i.e., an X axis extending along the ground surface () and a Y axis extending along the ground surface (). Bonding tool cooling time can be thereby reduced.

A retaining device for holding at a place a workpiece such as a lead frame including a pair of first slits formed so as to surround the bonding window opened in the retainer. Furthermore, second slits are formed so as to extend to the outside from the end portions of the first slits, thus forming first connecting areas; and third slits are formed on the outside of the second slits so as to be perpendicular to the first connecting areas, thus forming second connecting areas.

A microscope mount for mounting a microscope, which is used for observation of bonding conditions, etc., to a bonding machine including a supporting shaft, a microscope attachment shaft and a pair of swing plates rotatably connected to the supporting shaft at one end and to the microscope attachment shaft at the other end. Pulleys are fixed on the shafts, and a belt is installed between the pulleys. A microscope is mounted on the microscope attachment shaft, and the mount is attached to the bonding machine. When in this state the mount is rotated about the supporting shaft, the facing direction of the microscope on the attachment shaft can be kept the same.
