Modeling of the soldering process for components of radio-electronic units of on-board equipment

The technological route for the production of radio electronic printed units is considered. Determined that he most critical operation is reflow soldering in the vapor-gas phase. The most significant factors of this operation are revealed by the method of expert evaluation. To construct a mathematical model a fractional factor experiment was carried out. The regression equation is obtained and carried out its verification for adequacy. A motion was made along the response surface in the direction of the gradient of the linear approximation until the area of the extremum was reached. In this case, an increase in the quality criterion has been achieved.
