prepare the key for copper-plating by cleaning it with a thin layer of toothpaste or soap and water. dry it off on a paper towel. stir copper sulfate into some hot water in a beaker until no more will dissolve. your solution should be dark blue. let it cool.
electroplating: In copper electroplating, a metal substrate is placed in an electrolytic bath and an electric current is used to cause copper ions to adhere to the base materials surface. the result is a thin copper coating on the surface.
oct 26, 2013 take a fourth of the copper scoring pad and create a teardrop shape. you want the fatter end to be very tightly packed so that it doesnt float; the electroplating process creates bubbles which can get trapped in your wire mesh.
the concept of copper electroplating is straightforward: submerge the wafer to be plated into an electrolyte bath, apply a current, and copper ions will migrate and deposit onto regions with a pre-existing metal seed layer. figure image of electrolytic plating cell. the electrolyte bath contains three primary inorganic components:
