Air Oxidation Oxidation resulting when panels are exposed to ambient conditions. Also see Oxidation. A material made of chromic acid and sulfuric acid that was used as an early form of etchant solution chemistry. Chloride A molecule or compound that contains a chloride atom.
Chloride ions increase etch rates in etching solutions.
Conical Spray Nozzle A spray nozzle configuration that produces a cone-shaped spray. Complex A strong chemical bond also known as a Chelate. Conductor The copper circuitry on the printed circuit board. Controller A proprietary component to the alkaline etching system used to control copper concentration based on baume or specific gravity. The controller activates a pump that automatically adds replenisher at the prescribed copper concentration and removes spent etchant.
