Patent number: 8705249Abstract: Some invention embodiments relate to a method for forming a fuse which electrically connects two metal surfaces (2) that are arranged on a printed circuit board (4) next to each other and spaced apart from each other. It is provided according to the invention that the two metal surfaces (2) are each partially covered with a protective coating (5), wherein a partial region forming a contact region (2a) remains uncovered, liquid soft solder material (1) which bridges the gap between the two metal surfaces (2) is applied onto the two uncovered partial regions (2a), and the protective coating (5) in a surrounding area of the solder material (1) is removed after the soft solder material (1) has solidified, in order to form receiving regions (2b) which are wetted by the solder material (1) when the latter fuses, with the result that the solder material (1) flows off from a printed circuit board region (3) between the two metal surfaces (2) and the electrical contact formed by the solder material (1) is interrupted.Type: GrantFiled: September 1, 2010Date of Patent: April 22, 2014Assignee: Borgwarner Beru Systems GmbHInventors: Michael Luppold, Alexander Dauth

Patent number: 7911314Abstract: A electric circuit includes a connection to a current source, an electric load, and a thermal-mechanical fuse which, in the case of failure at an excessive heat emission, interrupts the current supply to the load, which is effectuated by a feeder in which is arranged a spring having two ends, at least one end is soldered to a solder point provided in the feed line. The one solder point is under a mechanical pretension caused by the restoring force of a spring, that separates the solder joint between the spring and the solder point in the feed line, when the solder melts at the solder point.Type: GrantFiled: July 21, 2007Date of Patent: March 22, 2011Inventors: Alexander Dauth, Jürgen Paul, Rolf Merte, Michael Luppold
