Abstract: A circuit board punching structure capable of preventing a copper sheet from warping. A circuit board motherboard comprises a circuit board region. Process edges are provided on two sides of the circuit board region. Multiple transverse cutting regions and multiple longitudinal cut recesses are provided in the circuit board region. The multiple cutting regions and the multiple cut recesses divide the circuit board region into multiple circuit board units. The multiple circuit board units are arranged in a matrix in the circuit board region. Four positioning structures are respectively provided on four corners of the circuit board motherboard. Half holes are respectively provided in the circuit board unit and the cutting region. The two half holes are connected to each other. A milling plate positioning hole is provided on one of corners of the circuit board unit. The circuit board motherboard has a multi-layer composite structure. The circuit board is provided with an auxiliary hole. When milling is performed on the half hole, since the copper sheet at the half hole has already been broken by means of the auxiliary hole, rotation of a milling cutter during movement thereof in a circuit board punching process will not cause copper sheet to roll up and catch at the half hole, thereby improving the yield of circuit boards.
