Abstract

The circuit device has a contact element, which electrically connects a wave guide (1) with a conductor strip (2). To avoid mechanical stresses due to thermal expansion the contact element is a pre-stressed prefabricated leaf spring having reproducible properties, which is bonded at one contacting area to the wave guide (1) or the conductor strip (2) by electrically conducting adhesive or glue, while a sliding contact is provided on the conductor strip (2) or the wave guide (1) at the other contacting area. The prefabricated leaf spring is preferably a MIGA leaf spring precisely made by UV depth lithography and multiplayer galvanic methods in a batch production process.
