1. A method for determining accuracy of a circuit assembly process, the method comprising the steps of: capturing an image of an assembly of a substrate, the assembly formed by the circuit assembly process, the image comprising a first shape representative of a first component of the assembly and a second shape representative of a second component of the assembly; identifying a first set of numeric coordinates defining a location of the first shape and a second set of numeric coordinates defining a location of the second shape; determining coverage of the assembly by calculating overlap of the first and second components from the first and second sets of numeric coordinates; and comparing the coverage to a threshold to determine accuracy of the circuit assembly process.
