[0025] figure 1 It is a flowchart schematically showing the circuit board processing method according to the present invention. As shown in the figure, according to the circuit board processing method of the present invention, the specific steps are as follows:
[0026] a) Glue the reinforcement board 2 on the first surface 11 of the circuit board 1. The area of the reinforcement board 2 is at least 85% of the area of the first surface 11 of the circuit board 1. At 80-170°C, the first surface The peel strength between 11 and the reinforcing plate 2 is greater than 35.0gf / mm;
[0027] b) surface mount (SMT) on the second surface 12 of the circuit board 1;
[0028] c) performing chip-on-board packaging (COB) on the second surface 12 of the circuit board 1;
[0029] d) Peel off the reinforcement board 2 from the first surface 11 of the circuit board 1 .
