Abstract
A microdeposition system () and method deposits precise amounts of fluid material onto a substrate. A microdeposition head () includes a plurality of spaced nozzles that fire droplets having a deposited width when deposited on the substrate. A positioning device moves the microdeposition head () relative to the substrate at a head speed. A controller () generates over-clocking signals at a rate that is substantially greater than the head speed divided by the droplet width to improve resolution. The controller () includes a positioning module that generates position control signals for the positioning device. The controller () includes a nozzle firing module () that generates nozzle firing commands based on the over-clocking rate to fire the nozzles to form droplets that define features on the substrate.
