The Aerosol Jet process is an enabling technology for creating fully printed electronic features and even complete devices on 3D automotive structures. Using this process it is possible to integrate circuits (3D MIDs), sensor networks or package SMDs on structural components from the micro scale through to large parts. The process works by jetting finely focussed aerosols, which contain functional materials, on to planar or 3D surfaces. In this way the fundamental building blocks of electronic systems (conductors, semiconductors, resistors and capacitors) of can be printed directly from CAD data. The technology works by using aerodynamic focusing of aerosols to deposit very fine patterns on planar and also 3D surfaces. A functional ink is placed into an atomizer which creates a dense aerosol of tiny droplets between 1-5 microns in size. Larger droplets cannot overcome the force of gravity and drop back into the ink and are recycled. The aerosol is carried by a gas flow to the deposition head. Within the deposition head, the aerosol is focused by a second gas flow and the resulting, high velocity converging particle stream is deposited onto the substrate creating features as small as 10 microns in size. A shutter and precision motion control system allows for the creation of complex patterns on the substrate. Key features of the process include the ability to: Process a wide range of functional inks: including metals, alloys, oxides, polymers or ceramic materials. Print on planar and 3D conformal surfaces. Print feature sizes below 10 microns to above 3mm wide (in a single pass). Precisely control layer thickness from 25nm to several microns in a single pass. Combine multiple material printing to create complete devices. This paper will describe the Aerosol Jet process and how it is being applied in printing novel electronics devices and systems.
