ABSTRACT:
Probe tips are produced from electrically conductive wire by electrolytic machining of a zone of the wire above a free end utilizing a liquid electrolyte layer in contact with this zone, a ring electrode surrounding this zone, and a layer of an insulating fluid into which the free end extends. The insulating fluid can be air where the electrolyte is a membrane between layers of air above and below the membrane, or a body of a liquid insulator below the electrolyte layer where the insulator and the electrolyte form a bath.
