A dual clutch actuation device generates the axial compression force required to compress a first and second set of frictional elements of a dual clutch module. The endoscope apparatus comprises an endoscope portion and a control and display unit. Vertically aligned apertures are formed in the hypotenuse and base sides for receiving therethrough a retaining stake. The LGA contacting portion is configured to have its contact regions electrically engage with an un-oxidized portion of the circuit board’s contact pad, thereby achieving an effective electrical connection between the LGA connector contact and the corresponding circuit board pad. In order to be able to solder without difficulties the solder onto work pieces that exhibit sensitivity to breakage it is proposed that the solder is heated, is applied to the work piece that is supported in particular in a spring-mounted manner, and is soldered-on subject to the influence of ultrasound.
