摘要:
A microdeposition system includes a stage, a printhead carriage, and a controller. The stage holds a substrate. The printhead carriage includes N printhead modules, where N is an integer greater than one. Each of the N printhead modules includes a printhead and an alignment mechanism. The printhead includes a plurality of nozzles that deposit droplets of fluid manufacturing material onto the substrate while relative movement between the substrate and the printhead is along a first axis. The alignment mechanism adjusts the printhead with respect to the printhead module. The controller controls the alignment mechanisms of the N printhead modules to set effective nozzle spacing for the pluralities of nozzles to a uniform value. The effective nozzle spacing is defined as spacing between adjacent ones of the plurality of nozzles as projected onto a second axis perpendicular to the first axis.
