Abstract
The utility model relates to a carbon oil printed circuit board and belongs to the technical field of printed circuit boards. The carbon oil printed circuit board comprises a printed circuit board substrate (1), a printed circuit (2), a carbon oil layer (3), a solder mask (4), a converter (5) and a protective printing ink layer (6), wherein the printed circuit (2) is arranged on the printed circuit board substrate (1), the carbon oil layer (3) is arranged in the printed circuit (2), the solder mask (4) is arranged below the carbon oil layer (3), the converter (5) is arranged at the middle of the printed circuit board substrate (1), and the protective printing ink layer (6) is arranged between the carbon oil layer (3) and the printed circuit (2). The carbon oil printed circuit board is advantageous in simple structure and convenient manufacture. With the carbon oil printed circuit board adopted, carbon oil does not ooze along a solder masking open window, and therefore, short-circuiting of the circuit board can be avoided; the carbon oil layer is narrow, and the carbon oil layer is basically the same with the circuit in width; and a centralized distribution mode is adopted, and therefore, process difficulty is small, and the carbon oil printed circuit board is easy to product, and the conductive property of the circuit board can be ensured.
