PRINTED CIRCUIT BOARD, MAINTENANCE METHOD THEREFOR, AND DISPLAY APPARATUS

Provided are a printed circuit board, a maintenance method therefor, and a display apparatus. In the printed circuit board, normal pads (300) that are not peeled off or damaged are first pads (310), each first pad (310) and a wire (200) connected to same have an integrated structure and are directly formed on a substrate (100). After a pad (300) at a certain position on the substrate (100) is peeled off, a second pad (320) can be provided at the position where the pad (300) is peeled off, so as to replace the pad (300) that was originally peeled off, and the second pad (320) comes into contact with the wire (200) and is fixed by solder (500), and a second pin (412) of a component (400) overlaps with the second pad (320) and is fixed by the solder (500). Using the second pad (320) to replace the peeled pad (300) for maintenance can avoid replacing the entire printed circuit board, thereby increasing the success rate of maintenance, reducing the production cost, and avoiding material waste.
