Aerosol Jet® Material Deposition for High Resolution Printed Electronic Applications
Aerosol Jet printing, is finding wide use in a number of electronic manufacturing applications. The Aerosol Jet systems deposit a wide variety of functional materials onto a wide variety of substrates without conventional masks or thin-film equipment. The process is non-contact, enabling
traces to be printed over steps or curved surfaces. Printed features can be from less than 10 microns to several centimeters, with thicknesses from 10's of nanometers to 10's of microns. The Aerosol Jet process utilizes both low viscosity inks and diluted pastes for an operating
range of approximately 1-1000cP. Typical materials that can be printed include nanoparticle metal suspensions, polymers and adhesives. Conductor traces can be printed using gold, silver or other nanoparticle inks. Conductors can also be formed by printing a seed layer, followed by electroless
plating. Polymer thick film pastes can be printed to form embedded resistors. Polyimide and various epoxies can be printed for adhesives, overcoat dielectrics, etc. The system also supports deposition of semiconducting inks, carbon nanotubes (CNTs) and biomaterials. The Aerosol Jet process
is compatible with a wide variety of substrates, including silicon, polyimide, glass, FR-4 and aluminum oxide. In principle, virtually any substrate can be used provided that the ink is compatible with the substrate. Applications for the Aerosol Jet technology include flexible displays, touchscreens,
fuel cells, high efficiency solar cells, 3-dimensional interconnects, and embedded components including sensors, resistors, and antennae. Aerosol Jet has distinct functional and cost advantages over traditional methods such as screenprinting, lithography and wirebonding. The solution also
compares well versus InkJet printing, especially in meeting high-volume manufacturing requirements. The Aerosol Jet process is compatible with a variety of substrates, including silicon, polyimide, glass, FR-4 and aluminum oxide. In principle, virtually any substrate can be used provided that
the ink is compatible with the substrate. Applications for the Aerosol Jet technology include flexible displays, EMI shielding, solder-free electronics, high efficiency solar cells, 3-dimensional interconnects, and embedded components including sensors, resistors, and antennae.
