The invention relates to a circuit board processing process. The circuit board processing process is characterized by comprising steps that S1, raw material sheet materials are prepared and pushed toa processing punch for cutting, and a cut circuit board blank has cut width of 20-30 mm and length of 40-50 mm; S2 of raw material transportation and cleaning, the circuit board blank cut in the S1 issent to a transport cleaning device for dust cleaning and sent out after cleaning; and S3 of circuit board module etching, a CNC machine tool completes the etching work after receiving the circuit board blank discharged from the transport cleaning device, and material receiving is performed. The circuit board processing process is advantaged in that processing efficiency is high, and a safety accident is not liable to occur.
