More Information
Summary:The invention relates to the technical field of PCB processing technologies, in particular to an identification method of a PCB and the PCB, and the method comprises the steps: S1, writing a processing program for milling the edge of the PCB on a numerical control encoder; S2, selecting a corresponding LOT number identification program according to the LOT number, and selecting a corresponding expansion and contraction identification program according to the expansion and contraction identification; S3, forming a corresponding LOT number groove and a corresponding expansion and contraction groove in the board edge of the PCB through the milling machine according to the selected LOT number identification program and the selected expansion and contraction identification program, and forming one LOT number groove and/or one expansion and contraction groove in one PCB through milling. According to the method, the PCB batch identification number and the PCB expansion and shrinkage identification can be quickly and
