Supply of high resistance carbon paste and carbon paste 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 performance, acid, alkali and chemical solvents erosion; with strong wear resistance, abrasion resistance, thermal shock resistance is good. Different models of high resistance carbon paste in accordance with the resistance from 100 ohms to 100,000 ohms range, different models have been deployed between the mutually desired resistance value customers in all kinds of circuit board have good adhesion.
