Classification: CPC H | IPC H

Claim 17:
18. A component comprising:
a main body having a surface with a main-body electrode thereon, the main body being made of a material having a first coefficient of the thermal expansion;
an external electrode positioned away from the main body, the external electrode being made of a material having a second coefficient of the thermal expansion that is different from the first coefficient of thermal expansion; and
a connecting material located between and making contract with the main-body electrode and the external electrode, the connecting material having a melting point that is below at least some of the operational temperatures of the component such that the connecting material changes from a solid state to a liquid state to relieve the mechanical stresses from the different coefficients of thermal expansion of the main body and the external electrode, the connecting material maintaining electrical connection between the main-body electrode and the external electrode when in both the liquid state and the solid state,
wherein the main body and the external electrode are pressed against one another by a prestressing unit.
