The burning tool 100 can be used for double-sided burning of a board to be burned, so as to improve burning efficiency. For example, the burning tool 100 burns the chip board to load the system program to the chip board.

Taking the case that the burning tool 100 burns a board to be burned as an example, the structure and function of the burning tool 100 will be described. The board body to be burnt comprises a plurality of first chips to be burnt and a plurality of second chips to be burnt, and burning contacts of the first chips to be burnt and the second chips to be burnt are located on two opposite sides.
