Abstract

PURPOSE:To enable deposits to be fully removed from a coated wire bonding tool in a short time by a method wherein frames are shot against the tip of the tool. CONSTITUTION:Thermally sublimatable coating 7 of a coated wire 5 are thermally sublimated into gas and solidified as deposits 8 to attach dispersedly to the tip 11A of a coated wire bonding tool. Inflammable gas is supplied to a torch tube 21 through the intermediary of a pipe and ignited at the outlet of the torch tube 21 to shoot a strong jet of flame 20 against the tip 11A of the coated wire bonding tool to heat it instantaneously to sublimate the deposits 8 quickly. By this setup, deposits are fully removed in a short time.

Therefore, when the coated wire is heated by using the coated wire bonding tool as described above, the thermally sublimable coating is sublimated to bare the core wire, and the bare core wire is reflow-soldered to sublimate. A part of the heat-sublimable coating thus formed comes into contact with the tool tip 11A after cooling to become a low temperature and adheres to the tool tip 11A. By repeating such wire bonding several times, this deposition progresses and accumulates to form a relatively large deposit 8.

When such a deposit 8 is generated in the tool tip 11A, especially in the arcuate recess, the end surface of the tool tip 11A comes into close contact with the outer peripheral surface of the coated wire 5 when the tool body 11 is pushed down. Is hindered. Therefore, the coated wire 5 does not rise to a predetermined high temperature, and the sublimation of the thermally sublimable coating 7 becomes insufficient, so that the connection strength of wire bonding decreases.

However, the conventional cleaning method in which the tool tip is rubbed with a cloth or the like which has been impregnated with a solvent to remove extraneous matter is to put the cloth in the arc-shaped recess of the tool tip with a finger. Since the rubbing is performed by pushing in, there is a problem that not only it takes time, but also there is a residue of adhered matter.
