What is Carbon Printed Circuir Board and What is its capability?

Carbon PCB Prototype
Carbon printing oil refers to the use of screen printing technology, printed on the PCB board designated position of carbon oil, after the oven curing test OK to form a qualified carbon film with a certain resistance value to replace the original resistance element. The production is similar to the character screen printing, except that the carbon oil has good electrical conductivity, and the character is a semiconductor material, only plays the role of marking and welding
