<p>PURPOSE: A method for cleaning a capillary of a wire bonder is provided to improve an operating rate by automatically withdrawing a wire though the lower side of the capillary after a cleaning process is completed. CONSTITUTION: It is determined whether the number of wire bonding operations exceeds a reference number in a capillary (S1). A wire is cut on the lower side of the capillary (S2). The wire is inputted to the inside of the capillary (S3). The lower side of the capillary is cleaned (S4). The wire is withdrawn (S5). [Reference numerals] (AA) Start; (BB) No; (CC) Yes; (DD) Finish; (S1) Does the number of wire bonding operations exceed a reference number ?; (S2) Cut a wire; (S3) Input a wire; (S4) Cleaning a capillary; (S5) Withdraw a wire</p>
