摘要： A device and method is available for detecting abnormalities of an electric discharge generated for forming a ball at the end of a bonding wire in a bonding apparatus. A high voltage is applied across the bonding wire and an electrode, and the maximum value of the applied high voltage is detected and sent, via a peak hold circuit, to a computer that compares the maximum high voltage with an insulation breakdown voltage of a normal detection range and calculates a gap between the end of the bonding wire and the electrode, thus determining the discharge abnormalities based upon the result of the calculation of the gap.

摘要： A method for cleaning a bonding tool of a bonding apparatus includes a step of positioning a tip portion of the bonding tool between a pair of discharge electrodes, which are primarily used for removing a covering that covers a bonding wire, and a step of causing an electrical discharge across the discharge electrodes by applying a high voltage, such as of 3500 V, by connecting the discharge electrodes to positive and negative poles of a discharge power source, respectively. The electrical discharge is performed with the bonding wire kept inside the bonding tool so as not to project out of the bonding tool or after the bonding wire is removed from the bonding tool.
