In a second operating condition, the base assembly of the magnetic clamping heat sink assembly is positioned in a second position adjacent to the ferromagnetic element, and the carrier body is driven downward against a force of the spring to a lower position and into contact with the base plate by magnetic attraction between the at least one magnet and the ferromagnetic element.

Systems and methods are presented herein for a method of attaching a strip to a housing. An internal support member is inserted into a collapsible housing, such that it is arranged along a longitudinal axis of an inner surface of the collapsible housing. An outer support member is arranged along an outer surface the collapsible housing opposite the internal support member. A strip is positioned along the outer surface using the outer support member and the internal support member. Then the strip is permanently welded to the outer surface using a welding element. Welding is performed by a welding element located in one (or both) of the internal support member or the outer support member.
