  • Publication number: 20240173961
    Abstract: In a printing method, at least one image of a substrate supported in a printing system is acquired. An actual position of a first alignment feature on the substrate in a frame of reference of the printing system is determined based on the at least one image. Expected positions of second alignment features on the substrate are determined based on the actual position of the first alignment feature. Actual positions of the second alignment features in the frame of reference of the printing system are determined based on the at least one image and the expected positions of the second alignment features. Target positions of print regions on the substrate are determined based on the actual positions of the second alignment features. Ejection of print material onto the substrate in the print regions is controlled based on the target positions of the print regions.

  • Publication number: 20240167143
    Abstract: 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.

  • Patent number: 11985887
    Abstract: A system may include a support surface for supporting a substrate, a plurality of first passages arranged to distribute flows of a first gas to establish a gas bearing to float the substrate above the support surface, and a plurality of second passages arranged to distribute flows of a second gas to convey the substrate along the support surface. A method may include floating a substrate above a support surface of a substrate support apparatus via a gas bearing; and while floating the substrate, conveying the substrate along the support surface by flowing gas toward a surface of the substrate and in a nonperpendicular direction relative to the surface of the substrate.
