Abstract:
A wire bonding method comprising:(a) imaging a bonding point with an imaging means;(b) displaying the image from the imaging means on a display means;(c) moving vertical marks on said display means to be centered on said bonding point to determine coordinates of the bonding point;(d) registering the bonding point by storing the image in an image data storage memory in a same order as coordinates of the bonding point are stored in a bonding point coordinate memory;(e) repeating steps (a)-(d) for each bonding point; and(f) retrieving a registered image of a bonding point stored in the image data storage memory and the associated bonding point coordinates stored in the bonding point coordinate memory for more easily and accurately checking and correcting the bonding point coordinates.
