Abstract:
1. A microdeposition system, comprising: a head including a plurality of nozzles; a controller that generates nozzle firing commands that selectively fire said plurality of nozzles to create a desired feature pattern; configuration memories corresponding to each of said plurality of nozzles, which each stores voltage waveform parameters that define a plurality of voltage waveforms; a selector that selects one of said plurality of voltage waveforms for each of said plurality of nozzles from said corresponding configuration memory; digital to analog converter (DAC) sequencers corresponding to each of said plurality of nozzles, which each outputs said selected one of said voltage waveforms from said corresponding configuration memory; DACs corresponding to each of said plurality of nozzles, which each outputs analog voltages based on said selected one of said voltage waveforms from said DAC sequencer; and amplifiers corresponding to each of said plurality of nozzles, which each drives said corresponding nozzle based on said analog voltages from said corresponding DAC.
