Methods for making electrical connections to obscured contacts on an electronic component, such as when an LED die is placed active side down on a transparent substrate, and devices manufactured therefrom. In some examples a conductive material, optionally with an underlying dielectric or insulating layer, is deposited on the component that wraps from the contact around to a component face which will not be obscured. After the face with the contact is placed on the substrate, connection can be made to the conductive material on the unobscured face. In other examples a contact can be disposed on a conductive bump on the substrate. Conductive traces on the substrate are shaped to prevent shorting between contacts. The faces of the die can be coated with a reflective material to increase the LED output in a desired direction, for example through the substrate.
Methods and apparatuses for printing a jet of ink, such as a jet produced by an aerosol jet apparatus or an ink jet printer. The print head is rapidly swiveled, tilted, pivoted, or rotated during deposition to print lines or other shapes on a substrate. Parallel lines and arbitrary shapes can be printed by shuttering the jet and/or moving the substrate relative to the print head. Metallic lines from the top surface to the bottom surface of the substrate can be wrapped around the edge of the substrate without losing electrical connectivity. In one example connections can be printed from a printed circuit board (PCB) to an integrated circuit on the PCB. The deposition rate can be over 50 mm/s, meaning that over 25 lines/s can be printed, depending on their length and thickness.

High reliability sheathed transport path for aerosol jet devices
An apparatus and method for depositing an aerosol that has an ultrafast pneumatic, shutter. The flow of aerosol through the entire deposition flow path is surrounded by at least one sheath gas, thereby greatly increasing reliability. The distance between the aerosol switching chamber and a reverse gas flow chamber input is minimized to reduce switching time. The distance from the switching chamber to the nozzle exit is also minimized to reduce switching time. The gas flows in the system are configured to maintain a substantially constant pressure in the system, and consequently substantially constant flow rates through the deposition nozzle and exhaust nozzle, to minimize on/off switching times. This enables the system to have a switching time of less than 10 ms.

Methods for welding materials such as superalloys, hard-facing materials, and aluminides that are difficult to weld without cracking. Instead of welding one layer at a time on the weld surface like existing methods, the weld comprises stacks of weld beads that are first built up vertically to a desired weld height. After a first stack is produced, the weld surface is translated relative to the filler material source and a second adjacent stack is produced. The process is repeated, traversing the weld surface. The stacks are preferably deposited at an angle to the filler material deposition direction. By building the thickness of the weld first, the heat of welding is preferably concentrated into a sufficiently small area on the weld surface so that weld pre-heating is not required, and each portion of the weld and weld surface undergoes only one heating and cooling cycle, reducing cracking.
Method and apparatus for splitting an aerosol flow into multiple streams prior to deposition. The aerosol flow is surrounded in each outlet by a sheath gas flow. Adjusting the sheath gas flow in each outlet determines the amount, if any, of aerosol transported through each of the outlets. For example, the sheath flow in an outlet may be increased until all of the aerosol flow through that outlet is diverted to one or more other outlets. One of the outlets can be an exhaust outlet, which can exhaust all of the aerosol produced by the system if the aerosol flows in the other outlets are stopped, thus preventing material settling and, in combination with increasing the sheath gas flows in the other outlets, enables fast shuttering rates. The sheath gas prevents the aerosolized material from building up on the bottom of the splitter chamber and inside the outlets.

Methods and apparatuses for controlling aerosol streams being deposited onto a substrate via pneumatic shuttering. The aerosol stream is surrounded and focused by an annular co-flowing sheath gas in the print head of the apparatus. A boost gas flows to a vacuum pump during printing of the aerosol. A valve adds the boost gas to the sheath gas at the appropriate time, and a portion of the two gases is deflected in a direction opposite to the aerosol flow direction to at least partially prevent the aerosol from passing through the deposition nozzle. Some or all of the aerosol is combined with that portion of the boost gas and sheath gas and is exhausted from the print head. By precisely balancing the flows into and out of the print head, maintaining the flow rates of the aerosol and sheath gas approximately constant, and keeping the boost gas flowing during both printing and shuttering, the transition time between printing and partial or full shuttering of the aerosol stream is minimized. The pneumatic shuttering can be combined with a mechanical shutter for faster operation. A pre-sheath gas can be used to minimize the delay between the flow of gas in the center and the flow of gas near the sides of the print head flow channel.

FABRICATION OF THREE-DIMENSIONAL MATERIALS GRADIENT STRUCTURES BY IN-FLIGHT CURING OF AEROSOLS
A method for fabricating three-dimensional structures. In-flight heating, evaporation, or UV illumination modifies the properties of aerosol droplets as they are jetted onto a target surface. The UV light at least partially cures photopolymer droplets, or alternatively causes droplets of solvent-based nanoparticle dispersions to rapidly dry in flight, and the resulting increased viscosity of the aerosol droplets facilitates the formation of free standing three-dimensional structures. This 3D fabrication can be performed using a wide variety of photopolymer, nanoparticle dispersion, and composite materials. The resulting 3D shapes can be free standing, fabricated without supports, and can attain arbitrary shapes by manipulating the print nozzle relative to the target substrate. Multiple materials may be mixed and deposited to form structures with compositionally graded material profiles, for example Bragg gratings in a light pipe or optical fiber, optical interconnects, and flat lenses.

DIRECT PATTERNING FOR EMI SHIELDING AND INTERCONNECTS USING AEROSOL JET
A miniaturized aerosol jet, or an array of miniaturized aerosol jets for direct printing of various aerosolized materials. In the most commonly used embodiment, an aerosol stream is focused and deposited onto a planar or non-planar target, forming a pattern that is thermally or photochemically processed to achieve physical, optical, and/or electrical properties near that of the corresponding bulk material. The apparatus uses an aerosol jet deposition head to form an annularly propagating jet composed of an outer sheath flow and an inner aerosol- laden carrier flow. Miniaturization of the deposition head facilitates the fabrication and operation of arrayed deposition heads, enabling construction and operation of arrays of aerosol jets capable of independent motion and deposition. Arrayed aerosol jets provide an increased deposition rate, arrayed deposition, and multi-material deposition. Applications for the miniaturized aerosol jet or jet array include direct patterning for EMI shielding and interconnects.
The present invention includes an apparatus and method by which the three-dimensional form or configuration of a distorted workpiece, such as a turbine component, is reverse engineered, and then this reverse engineering capability is combined with welding equipment, preferably a laser powder fusion welder, all integrally carried within a single machine, whereby a tool path unique to each workpiece is created and the welding machine accurately replaces lost material on the workpiece. The present invention consists of a series of operations or steps, preferably carried out by a single machine.
