Abstract
In the work theoretical and experimental methods were used to investigate temperature fields in the conditions of soldering the metal plates, contacting with a heated body. To determine thermal conditions, necessary to provide soldering (melting of solder in the joint zone), calculation of temperature distribution with time in the joint zone was carried out, depending on characteristics of «heater-plate-solder-plate» system and thermal resistance in contacts between the system elements. It is shown that by comparing the theoretically calculated and experimentally measured thermograms, it is possible to determine thermal resistance in the contact zones. On the basis of the obtained values of thermal resistance in the contacts, the modeling of thermal fields in the systems with the arbitrary dimensions of elements was carried out. 13 Ref., 7 Figures.
Keywords: thermal fields, non-stationary process, method of finite differences, reaction soldering, permanent joint, multilayer foil, local heating
