Waveform shaping interface

摘要

A method and system of facilitating development of fluids having a variety of elemental compositions are disclosed. A graphical user interface allows user interaction with a lab deposition system to control fluid drop ejection of fluids through multiple nozzles. Fluid drop ejection and drop formation can vary from fluid to fluid, and require adjustments to waveform parameters of a drive pulse applied to the multiple nozzles. The system implements a drop watcher camera system to capture real-time still and video images of fluid drops as they exit the multiple nozzles. The captured drop formation of the fluid drops are displayed to the user, and based on the images the waveform parameters are adjusted and customized specific for individual fluid. In addition to adjusting the drive pulse that effects fluid drop ejection, a tickle pulse can also be adjusted and customize to prevent clogging of the nozzles.

1. A system comprising:
a computer system configured to control a deposition system comprising a plurality of nozzles including a first nozzle; a graphical user interface to the computer system, the graphical user interface configured to control waveform parameters for jetting a fluid through the first nozzle, the waveform parameters depending on the fluid to be jetted; a camera coupled to the lab deposition system, the camera configured to provide real-time feedback information of a fluid ejected through the first nozzle, the graphical user interface configured to allow a user to adjust waveform parameters of a drive pulse delivered to the first nozzle based on the real-time feedback information; and a drop watcher communicatively coupled to the camera and a waveform editor, the drop watcher configured to display real-time still images and video images of the fluid jetting through the first nozzle.
