Abstract: A printer deposits material onto a substrate as part of a manufacturing process for an electronic product. At least one mechanical component experiences mechanical error, which is mitigated using transducers that equalize position of a transported thing, e.g., to provide an “ideal” conveyance path; a substrate conveyance system and/or a printhead conveyance system can each use transducers in this manner to improve precise droplet placement. In one embodiment, errors are measured in advance, with corrections being “played back” during production runs to mitigate repeatable transport path error. In a still more detailed embodiment, the transducers can be predicated on voice coils, which cooperate with a floatation table and floating, mechanical pivot assembly to provide frictionless, but mechanically-supported error correction.

Abstract: The present teachings relate to various embodiments of a gas enclosure system that can have a particle control system that can include a multi-zone gas circulation and filtration system, a low-particle-generating X-axis linear bearing system for moving a printhead assembly relative to a substrate, a service bundle housing exhaust system, and a printhead assembly exhaust system. Various components of a particle control system can include a tunnel circulation and filtration system that can be in flow communication with bridge circulation and filtration system. Various embodiments of a tunnel circulation and filtration system can provide cross-flow circulation and filtration of gas about a floatation table of a printing system. Various embodiments of a gas enclosure system can have a bridge circulation and filtration system that can provide circulation and filtration of gas about a printing system bridge and related apparatuses and devices. Accordingly, various embodiments of a gas circulation and filtration system as disclosed herein can effectively remove both airborne particulate matter, as well as particulate matter generated proximal to a substrate during a printing process. As such, various embodiments of a gas circulation and filtration system in conjunction with various embodiments of a gas purification system of the present teachings can provide for a controlled manufacturing environment resulting in a high-yield of OLED various devices.
