A method and device for determining manufacturing information about a printed circuit board (PCB). The method comprises: presetting a correlation between a plurality of pieces of manufacturing information about a PCB and a plurality of pieces of coding information (S202), wherein the coding information is generated by level signals of a plurality of pins of the PCB; when the PCB is processed, etching the plurality of pins according to the correlation (S204); and determining manufacturing information about the PCB through the level signals of the plurality of etched pins (S206). The problem that it is difficult to directly acquire manufacturer information in a PCB is solved. |
