  5. 19. Tidsoptimering av en lödprocess

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Mats Ahnelöv; [1995]
    Keywords : Solder process; Sequential control; Technology and Engineering;

    Abstract : This report investigates time optimization of a process where brazed heat exchangers are soldered in a vacuum furnace. This process consists of three phases, heating soldering and cooling. Physical models have been obtained by using stationary conditions. These are not sufficient to describe the actual very complex behavior. READ MORE
