Abstract:
A bonding method which prevents wire sweep, comprising steps of:connecting a wire to a first bonding point, moving a capillary straight up a first distance, moving the capillary a second distance away from a reference line of connection between the first bonding point and the second bonding point in horizontal direction thus making a first bent point and a second bonding point of the wire, again raising the capillary a third distance to extend the wire a predetermined length, whereas the first bent point is formed between the first distance and the second distance, and the second bent point is formed between the second distance and the third distance, and moving the capillary down to the second bonding point on which the wire will be bonded, wherein the wire connects the first bonding point to the second bonding point, and wherein the first distance, the first bent point, the second distance, the second bent point and the third distance of the wire are shifted to the side of the reference line thus increasing the resistance and the deformation space of the wire counter to the mold flow.
