System and method for side to side registration in a printed circuit imager
Abstract:
A method of recording aligned images on two sides of a printed circuit board substrate, comprising: recording an image of an electrical circuit pattern on a first side of a printed circuit board substrate; forming an alignment pattern on a side of the printed circuit board substrate, wherein said alignment pattern has a known spatial relationship to said image of an electrical circuit pattern; determining a location of the alignment pattern on the printed circuit board substrate; and recording an image of an electrical circuit pattern on a second side of the printed circuit board substrate in response to the determined location of the alignment pattern.
