Plating Services

Electroless gold is deposited from a solution purely as the result of the reaction of chemicals in the bath. The electroless plating bath is comprised of several of the same items found in an electrolytic gold plating bath, but it also includes chemicals (reducing agents) to provide electrons for the reaction and other chemicals (chelating agents and stabilizers) to control the reaction so that it can be predictable and controllable as a manufacturing process.   Why Does It Matter Which Process is Used to Plate?Is the Deposit the Same?To plate a part using an electrolytic process, every surface to be plated must be connected electrically so that it can act as the cathode in the plating cell. This becomes difficult for many products but especially for electronic circuits that generally need to have electrically isolated surfaces to be functional. Over the course of the development of the electronics industry it has become common practice to design in connections to tie different surface metal patterns together just for plating and then to remove these connections after plating. The manufacturing inefficiencies of this are obvious but a greater problem is the restriction this places on the final performance and circuit density of the component. Using electroless gold plating, circuits can be designed and fabricated in their final configuration. This saves the manufacturer several steps but more importantly it allows the circuit design to place primary consideration on optimum circuit performance and minimum circuit size. The electroless gold deposit is identical to an electrolytic pure gold deposit (i.e., Mil-G-45204 C Type III or ASTM B488 Type 1 hardness code A) in essentially every way; thickness, purity, hardness, grain size, density and color. The primary difference from an electrolytic gold deposit is it's second distinct advantage... improved thickness distribution. Electrolytic plating creates deposits that have thickness variations resulting primarily from the shape of the electrical field between the cathode surfaces and the anode. These deposits are thicker on corners and edges and surfaces where the distance to the anode is shortest. They are also thinner in the middle of surfaces, inside of holes and on surfaces facing away from the anode. Electroless plating completely eliminates this source of variation. Electroless gold plated deposits are uniform in thickness around corners, on both sides of a part, even on the inside walls of small holes that may be very deep.  

Nickel plating is an electrodeposit process that offers moderate corrosion and oxidization resistance. Nickel is sometimes used to build up worn or undersized parts. Nickel is highly recommended for increased ductility and corrosion protection . Bright finishes are obtained by using proprietary brightening agents. We offer Bright nickel and chrome plating.

We offer Zinc Plating exhibits good brightness, ductility and chromate receptivity, and has reliable and consistent coverage. Zinc plating is used extensively on Automotive, Aerospace and Military products.

Zinc plating is identical to electro galvanizing in principle in that both are electrode position processes. Zinc plating is used for coatings deposited on small parts such as fasteners, crank handles, springs, and other hardware items. The zinc is supplied as an expendable electrode in a cyanide, alkaline non-cyanide, or acid chloride salt solution. Cyanide baths are the most operationally efficient, but they potentially create a pollution and hazardous material problem.After alkaline or electrolytic cleaning, pickling to remove surface oxides, and rinsing, the parts are loaded into a barrel, rack, or drum and immersed in the plating solution. Various brightening agents may be added to the solution to add luster, but careful control of the bath and brightener is needed to ensure a quality product. Post-plating treatments may be used to passivate the zinc surface and at the same time impart various translucent colors to the coating. These post-plating treatments may be used to provide a desired color or to extend the life of the plated coating.The normal zinc-plated coating is dull gray in color with a matte finish, although whiter, more lustrous coatings can be produced, depending on the process or agents added to the plating bath or through post-treatments. The coating is thin, ranging up to 1 mil (25 µm), restricting zinc-plated parts to very mild (indoor) exposures. ASTM Specification B 633 lists four classes of zinc plating: FeZn 5, FeZn 8, FeZn 12 and FeZn 25. The number indicates the coating thickness in microns. The coating finds application in screws and other light fasteners, light switch plates and other small parts. Materials for use in moderate or severe applications must be chromate conversion coated.

Electroless means that the process used to plate the gold onto a surface is not the traditional electroplating cell having electrodes and an external power supply. Electroless gold is deposited from a solution purely as the result of the reaction of chemicals in the bath. The electroless plating bath is comprised of several of the same items found in an electrolytic gold plating bath, but it also includes chemicals (reducing agents) to provide electrons for the reaction and other chemicals (chelating agents and stabilizers) to control the reaction so that it can be predictable and controllable as a manufacturing process.

Electroless nickel plating improves corrosion resistance, increases the surface hardness of the material, provides a uniform and dense coating, and, in many cases, maintains the same surface finish the material had before plating.

Electroless nickel plating is a chemical process done without applying current by using auto catalytic chemical reduction process in higher temperature and it can be plated over a wide variety of metals like Aluminum, Mild steel, Hardened steel, Stainless steel, Copper and Brass. The main feature of electroless nickel plating is that being a chemical diping process, the deposition is absolutely uniform, and the dimension of components can be maintained within a close tolerance of 1 to 2 micron hence no need to carryout machining or grinding operations. Plating can be successfully acheived highly recessed areas such as deep bores, grooves and blind cavities, unlike in any conventional electrochemical process such as hard chrome plating.
