First unveiled back in 2014, the AJ 5X was developed for those customers working to develop electronics like molded interconnect devices (MIDs), sensors, smart phones, and tablets. Many customers use the system to work on more advanced fabrication projects, as it has the ability to print high conductivity inks and dielectric materials in complex shapes on a variety of substrates and 3D surfaces, which makes it possible to shrink electronic devices down.

Optomec’s Aerosol Jet technology accurately and precisely deposits electronic inks through the use of aerodynamic focusing. First, the material is place into an atomizer, which creates a mist of ink-laden droplets that is delivered to the deposition head. There, a sheath gas (usually compressed air or clean, dry Nitrogen) surrounds the aerosol as an annular ring to focus it. Once this gas and the aerosol pass through the profiled nozzle, acceleration occurs and the aerosol is focused into a tight stream of droplets that flow inside the gas, which also insulates the nozzle to prevent any material clogs.
“The resulting high velocity particle stream remains focused during its travel from the nozzle to the substrate over a distance of 2 to 5 mm maintaining feature resolution on non-uniform and 3D substrates,” the Optomec website states. “The system is driven by standard CAD data which is converted to make a vector based tool path. This tool path allows patterning of the ink by driving a 2D or 3D motion control system. Printed features range from 10 microns to millimeters.”
The patented Aerosol Jet process is used by many to make things like sensors, RF interconnects, flexible hybrid electronics, wire replacement bonds for IC packaging, and multi-layer, miniature circuits; the technology can even be used to 3D print antennas directly onto electronics enclosures.
