Abstract: A system for dispensing liquid onto a substrate, the system including: a liquid ejector to dispensing liquid droplets onto the substrate; and a motion controller to provide relative motion between the liquid ejector and the substrate, wherein the order of droplet dispensing is randomized relative to deposition locations on the substrate for a first plurality of the dispensed droplets.

Abstract: In example implementations, a method is provided. The method may be executed by a processor of a fluid dispensing apparatus. The method includes dispensing a fluid onto a surface from a dispenser during an alignment procedure. The surface is ejected for alignment verification. The surface is then received for re-execution of the alignment procedure after the alignment verification. The dispenser is re-used to dispense fluid onto the surface during re-execution of the alignment procedure.

Abstract: Systems, methods, and computer readable medium to provide patterned layer deposition of liquid types to a plate surface in layers organized in layouts with sites of patterns aligned to a plate origin of the plate surface. At least one layer includes a layout defining a geometric layout of the plate surface.
