Abstract
Systems and methods for aligning High Density Array ('HDA') pin plates, substrates and reservoirs with respect to each other. The system includes a flexure having a flexible print head, elongated members flexibly connected off-axis to the system and a pin plate support assembly detachably connected to the flexure allowing the pin plate assembly to adapt its position during a printing operation. The pin plate has alignment ball receptacles on its surface and the reservoir has alignment balls on its surface facing the pin plate. The pin plate is positioned with respect to the reservoir such that each of the alignment balls is located within one of the alignment ball receptacles to achieve the alignment. Once the pin plate is aligned, it is secured to a supporting assembly such as a vacuum bridge, and inking and printing operations are performed.
