Abstract
The invention relates to an electrode arrangement for a plasma jet device comprising a first and a second printed circuit board each having an exposed surface of a circuit path serving as electrode and facing the other printed circuit board, a spacer arranged between the first and second circuit board and a plasma cell arranged between the first and second printed circuit board and the spacer wherein the plasma cell has a gas inlet and a plasma outlet. The invention further relates to a plasma head comprising said electrode arrangement.
Claims13
An electrode arrangement for a plasma jet device comprising:
- a first printed circuit board having a first exposed surface of a first conductive track serving as a first electrode, and a second printed circuit board having a second exposed surface of a second conductive track serving as a second electrode;
- a spacer sandwiched between and in contact with the first and second printed circuit boards;
- a plasma cell formed by the first and second printed circuit boards and the spacer wherein the plasma cell has a gas inlet and a plasma outlet;
- wherein the spacer defines side walls of the plasma cell and a height of the spacer defines a distance between the first and second printed circuit boards and between the first and second electrodes;
- wherein the first exposed surface of the first conductive track is facing the second printed circuit board and the second exposed surface of the second conductive track is facing the first printed circuit board;
- wherein the first and the second printed circuit boards have an identical shape and are arranged in a mirrored position flipped by 180 degrees around a longitudinal gas flow axis between the gas inlet and the plasma outlet;
- wherein each of the first and the second printed circuit boards has a finger shaped projection providing an electrical connection located at a side of the gas inlet.
