Real-time measurement of the printed line of an aerosol jet printer provides a good indication of whether the printing process is correctly configured. However, the complexity of the printing process means that this endpoint measurement may not uniquely indicate the necessary process variables that need to be adjusted when print line quality decreases.

UW Madison researchers have developed a tool to make a droplet field measurement of the aerosol jet from the nozzle before it is deposited on the substrate. This enables droplet field measurement of velocity and mass distributions. The information from these distributions, lost after material is deposited on the substrate, allows superior control of the process variables that ultimately affect line quality.
