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: The laser-induced dispensing system incudes a cartridge assembly having a supply reel for supplying a foil having a light transmissive layer wound around the supply reel, and a take-up reel for taking up the foil. There is provided a coating device for coating the foil by a donor material during a motion of the foil. The laser-induced dispensing system also includes a irradiation head having optics configured for focusing a laser beam. Additionally, a controller, for controlling the cartridge assembly to establish motion of the foil, and the optics to focus the laser beam onto the foil at a location downstream the outlet of the coating device so as to release droplets of the donor material from the foil is provided.

Abstract: A laser-induced dispensing system for material processing is disclosed. The laser-induced dispensing system includes a fiber bundle having optical fibers. The optical fibers have first ends arranged at the first interface and second ends arranged at the second interface. Additionally, optics that direct laser beams transmitted from the second interface by the optical fibers toward a material to be deposited a substrate is provided. The optics is configured to focus the laser beams on the material to be deposited, thereby causing the material to be deposited to be released onto the substrate. Each of the optical fibers having a first end that is adjacent to a first end of another of the optical fibers at the first interface have a second end that is non-adjacent to a second end of the another of the optical fibers at the second interface.

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 in which a material or materials (e.g., a viscous material) are printed or otherwise transferred onto an intermediate substrate at a printing unit(s). The intermediate substrate having an image of material printed thereon is subsequently transferred to a sample building unit, and the image of material is transferred from the intermediate substrate to a sample at the sample building unit. Optionally, the printing unit(s) includes a coating system that creates a uniform layer of the material on a donor substrate, and the material is transferred from the donor substrate onto the intermediate substrate at the printing unit(s). Each of the printing units may employ a variety of printing or other transfer technologies. The system may also include material curing, heating, sintering, ablating, material filling, imaging and cleaning units to aid in the overall process.
