    摘要: This invention discloses a method for printed circuit board (PCB) inspection, including providing a multiplicity of PCBs placed on an inspection panel, defining each non-identical PCB in terms of geometry and features which are to be inspected, grouping the PCBs into at least one cluster, the at least one cluster being defined in terms of an amount, location and orientation of the PCBs in the at least one cluster, creating a reference image for the panel defined by a location and orientation of the at least one cluster on the panel and inspecting the panel by comparing sensed information with the reference image.

    摘要: Method and apparatus for automatically optically inspecting electrical circuits by matching portions of an electrical circuit being inspected to corresponding portions in a reference, wherein an adaptive spatial tolerance representing a permissible deviation in the location of corresponding portions is applied to a portion. The spatial tolerances for each portion is in part a function of a characteristic of the portion, for example one or more of: the proximity of the portion to other portions of predetermined type, a spatial location of the portion in an electrical circuit, a material from which the portion is formed, the color of the portion and the intensity of light reflected by the portion. Non-defective matching portions an electrical circuit being inspected and in a reference must be separated by a distance which is less than the adaptive spatial tolerance.
