Abstract
In accordance with the present invention, a heater element which includes a layer of ferromagnetic material is included in a connecting device along with a fusible material such as a solder preform. The connecting device includes, for example, a hollow sleeve formed of heat shrinkable material. The solder preform, the heater element and the heat shrinkable hollow sleeve are integrally formed as a self-contained solder sleeve device such that the heater element is separate from the objects to be joined and does not completely shield to generation of a inductive current in the objects to be joined. The connecting device thus promotes even flow and bonding of the fusible material around a junction between the objects. Further, a connecting device is provided which permits visual inspection of a connection between objects bonded upon activation of the connecting device, thus providing an opportunity to confirm the integrity of the junction.
