The WCET houses two Electro-hydrodynamic inkjet-printers from SIJ Technology, Inc. Capable of printing high-resolution traces with line-width and spacing in the order of 1 µm, using conducting, semiconducting and insulating materials. These printers use glass capillary tubes as jetting “nozzles” and are capable of jetting organic or water-based fluids with a wide range of viscosity (1cP to ~10000cP).
SIJ 050
Single AC nozzle system. Print area is 50mm x 50mm with a vacuum table.
SIJ 150
5 AC nozzle heads and 1 10kV DC micro-spraying head. The 5-nozzle system allows for automated sequential printing of different materials for multi-layer devices (e.g. electrodes and insulators). Print area is 150mm x 150mm with vacuum and print speeds of up to 50 mm/s.
