Method for realizing low temperature starting of equipment in circuit board

The invention specifically relates to a method for realizing low temperature starting of equipment in a circuit board. The method for realizing low temperature starting of equipment in a circuit board comprises adding a heating circuit near a chip having high requirement for temperature on the circuit board, wherein when the temperature of the circuit board is lower than a specific value and cannot satisfy the starting condition, the heating circuit starts working so that the temperature of the corresponding position of the circuit board starts to rise; when the temperature is greater than the specific value, the heating circuit stops working; when the temperature is lower than the rated value again, the heating circuit starts working again; and then the above process repeats. The method for realizing low temperature starting of equipment in a circuit board is simple in design and is convenient to use, and solves the problem that electronic equipment is difficult to start and is unable to start under lower temperature so that the equipment can start normally under the lower temperature environment and the reliability of electronic products can be improved under the lower temperature environment.
