    Abstract: Systems and methods for dispensing liquid materials as may be used in applications for coating flexible films and the like. Such a film may be coated by dispensing a rheological material onto its surface while drawing the film through a gap between a pair of rollers. The gap defines the thickness of a layer of the material applied to the film and is maintained at a desired width by microwires positioned through the gap. Another film across the gap from that to which the rheological material is applied aids in the coating of the layer and a contact area of the second film may be adjusted relative to the gap, e.g., when changing materials or when the coating film becomes abraded or deformed.

    Abstract: Laser jetting of droplets of a viscous material, such as an ink, is performed by coating a layer of ink on a mesh-like transport screen, with the ink being retained within spaces of the mesh-like transport screen. The ink-coated mesh-like transport screen is conveyed to a working area and a laser beam is used to heat the ink within the spaces of the mesh-like transport screen, thereby causing ink droplets to be jetted from the spaces of the mesh-like transport screen. Structures are formed on a receiving substrate arranged near the working area by jetting the ink droplets, either in an aggregation or sequentially, across a gap from the mesh-like transport screen to the receiving substrate and displacing the mesh-like transport screen and the laser beam relative to one another at times between the jetting of the droplets, or by directly printing ink droplets onto the receiving substrate.

    Abstract: In a first approach, a vacuum cell comprises a porous plate and a vacuum force generated by gas being drawn thorough the porous plate is used to pick electronic components from a donor substrate. After transport of the vacuum cell to a placing area, dots of liquid material may be deposited on a top surface of the porous plate adjacent to one or more picked components in order to disrupt the vacuum force and release the picked components onto a receiving substrate. In a refinement of the first approach, the porous plate contains a plurality of picking holes for selectively picking components. Certain picking holes can be fluidly coupled to the vacuum, allowing components to be attached within those picking holes, while other picking holes can be closed or rendered inactive with dots of liquid material deposited on a top surface of the porous plate.

    Abstract: Systems and methods in which dot-like portions of a material (e.g., a viscous material such as a solder paste) are printed or otherwise transferred onto an intermediate substrate at a first printing unit, the intermediate substrate having the dot-like portions of material printed thereon is transferred to a second printing unit, and the dot-like portions of material are transferred from the intermediate substrate to a final substrate at the second printing unit. Optionally, the first printing unit includes a coating system that creates a uniform layer of the material on a donor substrate, and the material is transferred in the individual dot-like portions from the donor substrate onto the intermediate substrate at the first printing unit. Each of the first and second printing units may employ a variety of printing or other transfer technologies. The system may also include material curing and imaging units to aid in the overall process.

    Abstract: Systems for material deposition. One such system includes a number of containers arranged relative to one another in a conical or other shape, pointing toward a common deposition point. When not actively depositing material, the containers are held at a distance from the deposition point. Another system has a rod disposed within a container and a flexible tip on the rod seals a material exit of the container when biased closed. Pressurized gas introduced into the container forces the rod away from the material exit and material from the container. In yet another system, a container includes a barrel adapter having a one-way air valve that seals the container and creates a vacuum, preventing material from leaking from the container. Upon application of a pressurized gas, the one-way valve is forced open and material is deposited from the container. The valve closes automatically in the absence of the gas.

    Abstract: A three-dimensional device is fabricated in a layer-by-layer approach using a support material. The support material is deposited in a liquid form on a surface, hardened by cooling or ultraviolet (UV) curing, and selectively ablated to create an area within which the desired structure of the device will be formed. Active material is deposited into this area, and the layer-by-layer process repeated until the three-dimensional device has been completed. Thereafter, any remaining support material is removed by water or other solvent.
