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: A vacuum chuck system may include a vacuum chuck and a vacuum stopper collection and dispensing system. The vacuum chuck may include a ceramic plate with a retaining surface. The retaining surface may include a plurality of depressions and a plurality of openings, each of the openings being disposed on a bottom surface of one of the depressions and fluidly coupled to a vacuum pump. Vacuum stoppers may be used to seal one or more of the openings so as to restrict the vacuum area of the vacuum chuck. The vacuum stopper collection and dispensing system may be used to collect vacuum stoppers from and dispense vacuum stoppers onto the retaining surface. In addition or in the alternative, an electromagnet or a robotic arm may be used to move a vacuum stopper from a blocking position to a non-blocking position on the retaining surface.

Abstract: A leveling system for a 3D printing system for laser dispensing includes inner and outer frames, each supported at its corners by respective actuators of first and second sets of actuators. The outer frame supports an optical plane within which material to be dispensed by laser irradiation is disposed. The inner frame supports a receiving medium plane within which a substrate on which said material to be dispensed by laser irradiation is disposed. Each actuator operates independently to displace a respective frame corner in the vertical direction. The inner and outer frames each is attached at their respective corners to a respective actuator by a rod, thus allowing the inner and outer frames to freely rotate with respect to one another. An additional frame may support sensors for monitoring the 3D printing system.

Abstract: Systems and methods for printing a printed circuit board (PCB) from substrate to full integration utilize a laser-assisted deposition (LAD) system to print a flowable material on top of a substrate by laser jetting to create a PCB structure to be used as an electronic device. One such system for PCB printing includes a jet printing unit, an imaging unit, curing units, and a drilling unit to print metals and other materials (epoxies, solder masks, etc.) directly on a PCB substrate such as a glass-reinforced epoxy laminate material (e.g., FR4) or others. The jet printing unit can also be used for sintering and/or ablation of materials. Printed materials are cured by heating or by infrared (IR) or ultraviolet (UV) radiation. PCBs produced according to the present systems and methods may be single-sided or double-sided.

Abstract: Systems and methods for the injection/dispensing of fluid material in a volumetrically accurate and repeatable manner via an injection cell that interconnects two reservoirs of the fluid material. The injection cell has a normally closed dispensing valve that is opened for dispensing of the fluid material during a compression cycle, and closed during a return cycle. Opening and closing of the dispensing valve is effected using either or both of pressurized air and/or a motorized linkage. During the compression cycle, independent longitudinal displacements of a piston cylinder and a piston within the injection cell act to first open the dispensing valve and subsequently eject fluid material within the piston cylinder via the opened dispensing valve. The piston cylinder and piston are returned to an initial state that facilitates reloading of the injection cell from the reservoirs and closes the dispensing valve during a return cycle.

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: Methods and apparatus for the fabrication of solid three-dimensional objects from liquid polymerizable materials at high resolution. A material is coated on a film non-digitally, excess material is removed digitally, by laser, leaving an image of a layer to be printed, and the image is then engaged with existing portions of an object being fabricated and exposed to a non-digital UV curing light source. Since the only part of the process that is digital is the material removal, and this part is done by laser, the speed of printing and the robustness of the manufacturing process is improved significantly over conventional additive or 3D fabrication techniques.

Abstract: A method for layer-wise additive manufacturing of a shaped body made up of slices of processed layers, including the steps: creating a layer of a slurry, the slurry including binder, a dispersing medium and a particulate filler material, solidifying the slurry layer, directing electromagnetic radiation to the solidified layer for processing it by debinding and/or sintering, and repeating the above-mentioned steps to successively build the shaped body. A laser induced forward transfer (LIFT) process utilizing a laser to direct laser beam pulses acts on a coating of slurry on a carrier to transfer droplets of slurry to a receptor surface to create the slurry layer which is then processed further by above-mentioned steps of solidifying, and debinding and/or sintering.

Abstract: Systems and methods for coating of a thin film with a viscous material, such as a liquid, a paste, or an adhesive, at a desired thickness. In such a system, two films move adjacent to one another, optionally in opposite directions, atop two rollers separated by a known gap that defines a coating thickness, with the material being transferred from one film to the other. The rollers may be maintained in their relative positions by springs and/or linear actuators and positioned using linear encoders. In alternate arrangements, the material to be coated could be low viscosity material such as a polymeric solution. Air knives may be provided near the gap to create an air flow that aids in preventing the free flow of low viscosity materials outside the bounds of the film during coating.
