- a) providing a first workpiece positioned at an origination location different from a target intermediate location;
b) providing a second workpiece positioned at a work location and having a target attach location different from said target intermediate location and said origination location;
c) performing a first place step to displace said first workpiece from said origination location to an actual intermediate location, wherein said actual intermediate location is different from said origination location and is identical to said target intermediate location or differs from said target intermediate location by an intermediate error deviation; and
d) performing a second place step to displace said first workpiece from said actual intermediate location to an actual attach location on said second workpiece, wherein said actual attach location is different from said origination location and said target intermediate location and is identical to said target attach location or differs from said target attach location by an attach error deviation.

Abstract
A method is provided for placement of a first workpiece onto a second workpiece. The first workpiece is initially positioned at an origination location and the second workpiece has an attach location different from the origination location. A first place step is performed to displace the first workpiece from the origination location to an intermediate location different from the origination and attach locations. A second place step is performed to displace the first workpiece from the intermediate location to the attach location and the first workpiece is attached to the second workpiece at the attach location.
