Abstract:
1. A method of performing a sequence of processing steps on a load supported by a processing plate, the method comprising: A) creating a sequential list of at least two applications to be performed in separate regions of the load, each of the at least two applications including respective processing steps; B) locating a coarse target of a first region of the load, the coarse target associated with a first application of the at least two applications; C) comparing predetermined coordinates for the coarse target of the first region with measured coordinates for the coarse target of the first region obtained from performing B); D) locating a panel target of the first region after performing C), the panel target of the first region associated with the first application; E) comparing predetermined coordinates for the panel target of the first region with measured coordinates for the panel target of the first region obtained from performing D); F) performing processing steps of the first application in the first region based on C) and E); G) locating a coarse target of a second region of the load after completing F), the coarse target of the second region associated with a second application of the at least two applications; H) comparing predetermined coordinates for the coarse target of the second region with measured coordinates for the coarse target of the second region obtained from performing G); I) locating a panel target of the second region after performing H), the panel target of the second region associated with the second application; J) comparing predetermined coordinates for the panel target of the second region with measured coordinates for the panel target of the second region obtained from performing I); and K) performing processing steps for the second application in the second region based on H) and J).
