Supply of high resistance conductive carbon paste, specifically for screen printing on rigid circuit board resistance (RESISTORS) designed for high-resistance carbon paste series. It phenolic board (FR2), epoxy resin panels (FR3) and glass fiber (FR4) and copper films have good adhesion to the circuit board industry in general use have a very good resistance to detergent force. Different models will have different resistance to adapt to a variety of requirements, with the series resistance from 0.1K ohms to 1KK ohms, all models can be mixed with each other to get the resistance can be accurately controlled. Widely used in circuit boards, printed circuits, potentiometers and other industries.
