Beschreibung
Zusammenfassung:	A process for soldering electrical components (2,3) onto a plastic film (1) having conductors with solder points, comprises heating the plastic film (1) on the opposite side to the components (2,3) then thermally insulating it. The plastic film is heated to a temperature below the damage temperature of the components (2,3). The component side of the plastic is then subjected to a hot gas stream (9), concentrated on the solder points, which is applied through stencil windows. The plastic film (1) and the components (2,3) are heated simultaneously, and the gas stream temperature controlled. The apparatus for carrying out the process comprises a hot gas blower, a heater plate (4) for preheating the plastic film (1), and a sheet metal stencil (5). The hot gas blower has positionable outlets.
