Electrode assembly

A method, comprising:

• positioning a roll of metal alloy in a stamping machine;
• unwinding, via the stamping machine, the roll of metal alloy;
• forming, via the stamping machine, a plurality of apertures within the roll of metal alloy;
• cutting, after the plurality of apertures have been formed, the roll of metal alloy into a plurality of electrode blanks with the apertures formed therein;
• and
• forming a plurality of electrodes by bending each of the electrode blanks in a manner such that each of the electrode blanks includes a central portion, a first flange, and a second flange, wherein the first flange and the second flange are disposed on opposite sides of the central portion;
• inserting at least a first electrode of the plurality of electrodes through an opening of a substrate;
• and
• attaching a wire to the first flange of the first electrode.

A method of fabricating an electrode assembly, comprising:

• providing a plurality of electrodes, wherein each of the electrodes includes a central portion, a first flange, and a second flange, wherein the first flange and the second flange are disposed on opposite sides of the central portion;
• providing a substrate having an elongate stem portion and a plurality of electrode connection structures coupled to the elongate stem portion, wherein each of the electrode connection structures includes a first coupling end, a second coupling end, a first opening disposed between the first coupling end and the second coupling end;
• inserting each of the electrodes into a respective one of the first openings such that the first coupling end makes a physical contact with the first flange and that the second coupling end makes a physical contact with the second flange;
• bonding the first and second flanges of the electrodes to the first and second coupling ends through a press fitting process;
• placing a plurality of wires of a wiring assembly onto the first flanges of the electrodes, respectively;
• and
• welding the wires to their respective first flanges through a resistance welding process.
