ABSTRACT:
A soldering device comprising at least one strip electrode which can be electrically heated and wherein so as to avoid thermal deformation and to assure good contact between the stirrup electrode (B) and the soldering joint wherein at the outer ends of the soldering strip (Ls) of the stirrup electrode (B) is closed expansion-compensation guards (AK) are provided which are U-shaped and which are attached to the soldering strip (Ls). Vertically extending retaining strips (Hs) are attached to the ends of the expansion-compensation guards (AK) so as to provide soldering which is particularly suitable for soldering high-pole electronic components on a PC board. The two retaining strips (Hs) may be approximately one-half the length of soldering strip.
