The invention relates to the technical field of PCB (Printed Circuit Board) processing technologies, in particular to a processing method for improving the alignment precision of a U-shaped clamping groove of a PCB. The processing method comprises the following steps of: S1, writing a processing program of the U-shaped clamping groove on a numerical control encoder according to the position, the shape and the size of the U-shaped clamping groove to be processed, and simulating a processing path of the U-shaped clamping groove; S2, connecting the numerical control encoder with a drilling machine, and recognizing the position of the U-shaped clamping groove to be processed on the PCB by the drilling machine according to the machining program; and S3, drilling the U-shaped clamping groove in the PCB according to a groove drilling instruction of the machining program by the drilling machine. The processing method can quickly and accurately process the U-shaped clamping groove with high precision. 本发明涉及PCB板加工工艺技术领
