    Abstract: Systems and methods for coating 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 alternative 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.

    Abstract: A dispensing unit for dispensing liquid material includes a hollow reservoir for accommodating a syringe and having an elongated nipple at one end of the reservoir, a piston including a shaft disposed therein, and a bracket adapted to receive the nipple of the reservoir and the piston. The reservoir nipple provides a fluid path for liquid material dispensed from the syringe supported in the reservoir. The bracket receives the nipple of the reservoir such that the fluid path for the liquid material is oriented towards a nozzle disposed in the bracket. The nipple also has holes disposed near an end thereof, and the bracket is adapted to receive the piston oriented with respect to the reservoir nipple such that the shaft of the piston is aligned with the holes in the nipple and the nozzle. The shaft is displaceable through the holes in the nipple towards the nozzle.

    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: 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: 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.
