Inkjet printing of nano particles is a new technology for the manufacturing of Printed Circuit Boards. Inks containing silver, copper or Carbon Nano Tube particles were deposited on various substrates like polyimide, Fr 4, paper or even wood with a special inkjet system as well as with standard office printers. Depending on the ink composition, at temperatures from 150-250 °C sufficient electrical conductivity was achieved. The capability of functional inkjet printing is demonstrated with a FM radio which was printed with silver ink, the components being attached by isotropic conductive glue.
