Silver/carbon hybrid conductive ink and ink-curing unit use microwave-heat printing technology to form traces on flexible printed circuits. Uses selective microwave heating and novel Photonic Curing process for printing on low-heat-resistant plastic films and roll-to-roll continuous printing. Controls spark discharge by separating microwave’s magnetic field and electric field and applying the fields separately in heating. Uses novel silver/carbon hybrid conductive ink, in which carbon particles (which do not develop a phase change during heating) have been added to silver particles to ensure uniform curing of ink under microwave heating, preventing a nonuniform distribution of conductivity.
