Aerosol jet printing operates by first atomizing an ink solution into a fine aerosol mist using an atomizer, such as ultrasonic or pneumatic. The aerosol is then transported by a carrier gas to a deposition nozzle, where it is focused into a narrow jet using a sheath gas. This focused aerosol jet is directed onto a substrate, allowing for precise, high-resolution deposition of materials.
Aerosol Jet Process:
1. An ink, such as a conductor or dielectric, is atomized within the Print Module creating a dense aerosol with a tight distribution of droplet sizing.
2. The aerosol is transported to the Print Head using high purity nitrogen as a carrier gas.
3. The aerosol is focused within the Print Head by an annular sheath of nitrogen focusing and accelerating the material onto the substrate as it travels through the nozzle.
4. The Print Head’s in-line shutter facilitates fast feature termination. Interchangeable Print Heads with various nozzle geometries allow for feature size flexibility.
