The invention relates to the field of circuit board machining, in particular to a drilling method for a large-sized circuit board. Through a workbench, a first positioning hole is formed in a first area of the circuit board, and a first positioning piece is arranged on a backing plate of a workbench; and through a workbench, a second positioning hole is formed in a second area of the circuit board, and a second positioning piece is arranged on a backing plate of the workbench. Circuit board position mounting errors caused by inconsistency of a setting tool of the positioning holes and a setting tool of the positioning pieces are avoided. Further, in the drilling process, the same reference point serves as a coordinate reference point for drilling in the first area and the second area, so that machining errors caused by inconsistency of reference points adopted by the workbenches are overcome. The production quality of the circuit board is improved, and the rate of finished products is increased. 本发明涉及电路板加工领域，
