Abstract
The invention relates to a process for soldering electrical components to soldering positions, which are provided with soldering material, on a plastic sheet provided with applied conductor tracks. The plastic sheet is heated, from the side which is remote from the components, to a below its damage temperature and after heating its side which is remote from the components is thermally insulated. Then, the side which faces the components is acted on by a heating-gas stream which is concentrated onto the locations which are to be soldered by a template which has windows.
