The invention provides a pore opening method and pore opening apparatus for a printed circuit board in a mobile terminal. The method comprises: W mechanical holes from an Mth board and an Hth board are formed under a first device, wherein the H and the W are positive integers and the H is larger than M and is less than N; and Q blind holes are formed from a first board to the Mth board under the first device, wherein the M and the Q are positive integers, the M is less than the N, and the Q is the double of the W. According to the invention, automatic pore opening designing is carried out under the device, so that the uniformity and consistency of pore opening are improved. Meanwhile, pore opening can be carried out on the PCB continuously, so that the pore opening efficiency is improved.
