Drum fixture and drum treating unit and drum treating method using the same fixture

Abstract

A spool gripper (20) is coupled to any one of flanges (12) provided at both sides of a spool (10) wound with a semiconductor device bonding wire thereon. The spool gripper has an inner diameter portion (22) for receiving a spool holder when the spool is fitted to the spool holder, a coupling portion (24) coupled to the circumference of the flange (12) while bearing a diameter larger than the inner diameter portion (22), and an outer diameter portion (26) with a diameter larger than the coupling portion (24). The worker grips the outer diameter portion (26) to handle the spool (10). The handling of the spool can be made without directly touching the spool. The wire bonding operation is made while the gripper being coupled to the flange. Therefore, it is not needed that the gripper (20) should be decoupled from the flange (12) to make the wire bonding operation. Accordingly, the durability of the gripper and the reliability in the spool holding can be maintained without deterioration while preventing separation of the spool from the gripper. Irrespective of the length of the spool holder or the presence of the spool fixation member, the spool handling unit can be used with any typed spool holder.

Description

technical field [0001] The present invention relates to a soldering wire assembly for processing semiconductor chip packages, in particular to a reel clamp detachably mounted on the flange of the reel; the invention also relates to a method of handling a reel using the reel clamp , this method can effectively prevent the welding wire from being polluted and damaged due to the carelessness of the staff. Background technique [0002] In general, a bonding wire assembly is a device for electrically connecting a lead wire of a lead frame to a bonding pad of a semiconductor chip having electrical characteristics through a conductive wire such as a high-purity platinum (Pt) wire or aluminum Silk. [0003] A wire assembly typically has a spool, spool clamp, wire supply guide, wire clamp, and capillary. The conductive filament is wound on a spool, and the spool is mounted on a spool clamp. The conductive filament is melted by a capillary and a welding torch, and soldered to the p...

Problems solved by technology

Therefore, the wire will be contaminated and damaged

[0016] Also, when the reel clamp is longer than the sum of the lengths of the reel and the handle, the reel cannot be fully fitted in the reel clamp, so that connection and detachment of the reel by the base is not easily performed

When the spool clamp has a clamp handle at its end, the clamp handle is internally caught by the handle of the base, so that the base cannot be used to connect and detach the spool, while limiting the capacity of the spool magazine. Available range
