Aiming at the mechanism model analysis of the"furnace temperature curve"and the optimal design of the reflow furnace parameters,the zero-dimensional numerical analysis model of the furnace temperature curve based on the lumping parameter method and the objective programming model of the optimal reflow furnace parameters were established by using the attached data and the basic physical laws and heat transfer laws.Finally,the corresponding furnace temperature curve under the temperature condition required by the problem and the optimal furnace temperature curve under the required conditions and the temperature zone setting temperature,the speed of the conveyor belt through the furnace and the corresponding minimum area under the furnace temperature curve are solved.final application using matlab software programming to solve the model.
