Abstract:

The present invention provides a method for automatically defining a part model for a semiconductor component. An image of the component is provided. The automatic method may be any of a trial and error method, systematic method or a method based on distance-angle signatures. The trial and error method is described in the context of defining a part model for a ball grid array. The systematic approach is described in the context of a leaded semiconductor and the distance angle signature approach is described in the context of defining a part model for an odd form semiconductor component.
