Contacts of a multipin connector may be soldered to leads of a board of the like by forming coatings of magnetic materials on each contact and locating the contacts between poles defined by an air gap of the magnetic core, each pole having a separate pair of opposed pole pieces disposed adjacent a pair of contacts whereby upon application of a constant a.c. current to a coil wound about the core the magnetic material is heated to a temperature approaching its Curie temperature whereby temperature regulation occurs. |
