PCB board printing process is mainly printed on the PCB board processing carbon film conductive layer and carbon film resistor layer, the high temperature (180 °C ~ 200 °C) polymerization film.
The PCB board printing process is mainly a method for processing a resistor body of a potentiometer or a resistance type sensor. At present, it is mainly used for potentiometers, automobile air-conditioning damper sensors, automotive wipers, automotive dimmers, and resistance type controllers.
On the 21st, the average price of carbon film printed circuit boards in Shenzhen was approximately RMB 3.80/PCS.
