Optomec direct-write aerosol jetting

The laser module adds the additional capability of curing materials, even on low temperature targets. A continuous conveyor belt transports the work pieces beneath the pulsing lamp units for high speed processing. YAG laser, however a variety of lasers may be employed so that the deposit, aerosol, or target is absorbing at the laser wavelength.

A detachable optomec direct-write aerosol jetting also means that interchangeable nozzles may be used.

A method as recited in claim 37, wherein said conductive feature has a thickness of at least about 0. Aerosol Jet technology is used to print a wide variety of materials, including conductive and ceramic inks suitable for antenna and sensor applications.

A method as recited in claim 37, wherein said conductive trace has a resistivity of not greater than about 10 times the resistivity of bulk copper metal. The largest structures deposited using extended nozzle 10 in a single pass of the deposition head may have linewidths approximately as large as the diameter of exit orifice One requirement of the material to be deposited is a uniform colloidal particle size distribution within the liquid suspension.

The apparatus of claim 7 wherein said extended nozzle is reattachable to said flowhead without requiring realignment. A method as recited in claim 37, wherein said substrate is an organic substrate. The minimum feature size attainable with this method was reported to be approximately microns.

The deposited linewidth can be approximately from as small as one-twentieth the size of the orifice diameter up to the size of the orifice diameter. The formulation is an improvement over previous copper formate solutions, and comprises a crystallization inhibitor selected from glycerol, citric acid, malic acid, malonic acid, and glycine.

The present invention includes several methods to increase the gas stream density. Various embodiments of the invention, the atomizer 12 may comprise a device that utilizes an ultrasound or pneumatic device, or that employs a spray process, forms an aerosol or condenses particles from a vapor.

Enhanced deposition characteristics include improved collimation of the jetted aerosol stream, improved focusing of the stream, minimized particle overspray, and facilitated delivery of material into recessed features.

The nozzle and collection probe are preferably opposed to each other along the axis of the chamber. Discussion of such publications herein is given for more complete background of the scientific principles and is not to be construed as an admission that such publications are prior art for patentability determination purposes.

This evaporation allows for the modification of the fluid properties of the aerosol for optimum deposition.

The goal of incubation is to produce a desired biochemical reaction, such as the development of enzyme activity.

Aerosol Jet 3D Printing – Electronics

The deposited feature size is dependent on the diameter of the deposition stream but also on the particle inertial momentum. The high absorption coefficient at the laser wavelength allows for very localized heating of the deposit, which in turn may be used to produce fine deposits for example, as small as 1 micron for a frequency-doubled Nd: The plasma does not require a vacuum environment, and can be integrated directly within any of the direct-write printing systems.

This is also somewhat dependent upon the viscosity of the start material. One embodiment of the invention may be implemented at a relatively low range of temperatures. These properties enable the deposit of structures with intricate geometries. The extended nozzle increases the working distance; that is, the distance from the flowhead to the target.
