Temperature control plays a vital role in the circuit board production process. In order to control the temperature change in the reflow oven, we establish a differential equation model of the PCB heat transfer based on the theory of heat transfer and use the boundary conditions to solve the temperature distribution in the oven. We also accurately simulate the heating and cooling process of the PCB. According to the requirements for the shape of the oven temperature curve in actual production, we respectively use the heating factor and the area enclosed by the temperature as evaluation indicators, establish a target optimization model, and obtain the best set temperature for each temperature zone and the best transmission speed of PCB board. Through analysis of different cases, we could get the conclusion that the model in this paper is reasonable and effective.
