	Plating - Wikipedia, the free encyclopedia
		Plating is indispensable as a corrosion inhibitor for the manufacture of computers, mobile phones, and electronic devices as well as other uses such as solderability, hardness, wearability, friction loss, paint adhesion, conductivity, shielding, etc. Moreover, it is a key technology for the development of new machines.
		Electroless plating, also known as chemical or auto-catalytic plating, is a non-galvanic type of plating method that involves several simultaneous reactions in an aqueous solution, which occur without the use of external electrical power.
		Gold plating is often used in electronics, to provide a corrosion-resistant electrically conductive layer on copper, typically in electrical connectors and printed circuit boards.

	Copper plating - Wikipedia, the free encyclopedia
		Copper plating is the process in which a layer of copper is deposited on the item to be plated by using an electric current.
		Often various other chemicals are added to improve plating uniformity and brightness.
		Without some form of additive, it is almost impossible to obtain anything close to reasonable plating.

	Acid Copper Through-hole Plating
		During panel plating, the entire copper surfaces on both sides of the substrate, as well as the hole walls are plated up to a desired final thickness.
		Pattern plating, as the name implies, involves masking off most of the copper surface and plating only the traces and pads of the circuit pattern.
		To normalize the plating field, it is often beneficial to add an exposed ¾" boundary around the board to increase to total plating area and suppress the formation of high potential areas at the edges of the pattern.

	Feature Article - Copper Plating
		The low metal and high cyanide levels in the copper strike are responsible for the low efficiency, but these same properties ensure against a non-adhering immersion layer of copper forming on the surface being plated.
		A high-throw bath can plate almost as much copper in the holes of printed-circuit boards, where current density is very low, as it plates on the surfaces of the boards.
		As with sulfate acid copper baths, pyrophosphate plating baths form immersion coatings on active metals such as steel and zinc die castings and thus strike layers such as cyanide copper must be used.

		Copper is an excellent undercoat for subsequent deposits, since it is a good metal to cover substrate defects such as holes and splinters, which enhance corrosion.
		Copper is among the least expensive metals and is in relatively stable supply.
		Typical plating bath compositions and operating characteristics are shown in Table I. A cyanide copper strike bath is typically used to deposit a thin, adherent layer that can completely cover an active metal surface such as zinc or steel prior to further plating operations.

	Acid copper plating tank
		Acid copper plating is one of the most forgiving of the electrochemical processes encountered in manufacturing printed circuit boards.
		The action of the ionic current in an electrolytic copper plating tank is such that, during plating, any and all suspended particulates will be forced toward the cathode (the panel that you are plating) and deposited.
		This will improve the plating uniformity along the edges of your board, which is especially important if you at plating through-holes that are near one of the edges.

	Copper Plating FAQ - first set
		To insure that all of the through-holes in your finished board are completely covered with a uniform layer of copper, it is essential that the conductive ink layer deposited during activation be as conductive as possible to optimize deposition and adhesion.
		OFHC copper, copper plumbing pipe, or copper wire is not sufficiently pure to avoid the presence of copper particles in the plating solution.
		Copper plating is also very handy if you do not have a way to create negative artwork.

		For the restorer, copper plating must be one of the most useful repair tools there is. By applying layers of copper, and sanding between applications, an incredibly smooth surface can be quickly built up, covering scratches and minor pits caused by corrosion.
		A final layer of copper plate to seal over the solder filler can then be buffed and polished to a high quality luster.
		Copper can be used to 'electroform', making complete objects from pure copper, by simply making a mold from wax and conductive powder, copper plating the mold, then melting the wax.
