The invention relates to a circuit board processing method, comprising: a) bonding a reinforcing plate on a first surface of the circuit board, wherein the area of the reinforcing plate is at least 85% of the area of the first surface of the circuit board, and in the range of 80 to 170 DEG C, the peeling strength between the first surface and the reinforcement plate is greater than 35.0 gf / mm; b)performing surface mounting (SMT) on the second surface of the circuit board; c) performing chip-on-board (COB) packaging on the second surface of the circuit board; and d) peeling the reinforcementplate from the first surface of the circuit board. According to the method of the invention, the deformation of the circuit board in the processing process can be effectively controlled. By effectively controlling the area ratio of the reinforcing board to the circuit board to be processed, the deformation of the circuit board can be avoided in the reflow soldering process, the area of the reinforcing board can be reduced, and the peeling workload and the peeling difficulty of the reinforcing board can be simplified and reduced.
