Laser patterning skew correction

摘要

A laser patterning alignment method provides a way to position a target at a working distance in a laser patterning system such that fiducial marks on the target are positioned in view of at least three laser patterning system cameras, and with each laser patterning system camera, to locate a fiducial mark on the target and sending location data of the located fiducial mark to a controller, to determine corrections required to align expected fiducial mark locations with the sent fiducial mark location data, and to adjust the laser patterning system with the determined corrections.
