Supply of conductive carbon ink, conductive carbon ink is a liquid thermal solid ink, the cured film has a protective role of copper foil and the electric current, has good conductivity and low impedance; it is easily oxidized, stable, acid , alkali and chemical solvents erosion; with strong wear resistance, abrasion resistance, thermal shock resistance is good. There are many different models for different types of electronic printing applications, such as PCB, membrane switches, printed circuits, solar cells, RFID tags and other electronic components industry.
