Publication number: 20130209670Abstract: The disclosure relates to a method and apparatus for preventing oxidation or contamination during a circuit printing operation. The circuit printing operation can be directed to OLED-type printing. In an exemplary embodiment, the printing process is conducted at a load-locked printer housing having one or more of chambers. Each chamber is partitioned from the other chambers by physical gates or fluidic curtains. A controller coordinates transportation of a substrate through the system and purges the system by timely opening appropriate gates. The controller may also control the printing operation by energizing the print-head at a time when the substrate is positioned substantially thereunder.Type: ApplicationFiled: February 22, 2013Publication date: August 15, 2013Applicant: KATEEVA, INC.Inventor: KATEEVA, INC.
