Abstract: The invention relates to a method for producing a conductive contact part for a detachable electric plug-in connection. Said method provides a contact element comprising a bushing part, sections of which contain longitudinal slits and which has ribs distributed around its periphery. A sleeve part, which can surround the bushing part and cover the ribs, comprises two opposing end faces. The sleeve part is placed and positioned in an approximately coaxial manner in relation to the bushing part, in such a way that it covers the ribs, the positioned sleeve part being locked by one of its two faces on the bushing part. The bushing part is elastically twisted about its central axis, in such a way that the ribs are towards said central axis and the other face of the sleeve part is locked on the bushing part that is held in a twisted position against the elastic restoring force of the ribs.

Abstract: A method and apparatus for soldering surface-mountable components to a printed circuit board includes a soldering head have a suction pipette located in the center of a thermode with a rectangularly arranged set of soldering stirrups. The thermode and suction pipette are individually vertically moveable relative to one another for precise positioning of a surface-mountable component at a predetermined position on a printed circuit board. Soldering at a predetermined solder location with positional correctness is accomplished in a single work cycle.
