Carbon ink is printed on PCB surface as a conductor to connect two traces on PCB. For carbon ink PCB, the most important is the quality and resistance of carbon oil, meanwhile, the Immersion silver PCB and Immersion tin PCB cannot be printed carbon oil, because they are Oxidizing.Meanwhile, the minimum line space should be more than 0.2 mm so that it is easier to manufacture and control without the short circuit.
Carbon ink can be used for keyboard contacts, LCD contacts and jumpers. The printing is performed with conductive carbon ink.
