Electric arc. An electric arc between two nails. An electric arc (or arc discharge) is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma, which may produce visible light. An arc discharge is initiated either by thermionic emission or ...
Electroetching is a metal etching process [1] that involves the use of a solution of an electrolyte, an anode, and a cathode. The metal piece to be etched is connected to the positive pole of a source of direct electric current. A piece of the same metal is connected to the negative pole of the direct current source and is called the cathode.

The primary properties of the photoresist are resolution capability, process dose and focus latitudes required for curing, and resistance to reactive ion etching. [ 14 ] : 966 [ 15 ] Other key properties are sensitivity, compatibility with tetramethylammonium hydroxide (TMAH), adhesion, environmental stability, and shelf life.
A small wood engraving by Ralph John Beedham. Ralph John Beedham (1879–1975) was a British wood-engraver. He occupies a unique position in the history of twentieth-century wood-engraving because, being a formschneider, he was probably the last person in Britain to serve an apprenticeship as a professional reproductive wood-engraver.
