There are several types of gold plating used in the electronics industry: • Soft, pure gold plating is used in the semiconductor industry The gold layer is easily soldered and wire bonded Its Knoop hardness ranges between 60 and 85 The plating baths have to be kept free of contamination• Soft, pure gold is deposited from special electrolytes Entire printed circuit boards can be plated This technology can be used for depositing layers suitable for wire bondingDial in the recommended voltage, which in most cases will be 5 to 6 volts and immerse the article into the gold plating solution and slightly agitate for Plating Guide by Pepetools
The solution is infused with an electric current that causes the gold to adhere to the surface of the substrate The resulting gold layer only qualifies as gold plated if it is at least 7 millionths of an inch thick and at least 10K A surface plating of blue gold on karat gold or sterling silver can be achieved by a gold plating of the surface, followed by indium plating, with layer thickness matching the 1:2 atomic ratio A heat treatment then Colored gold

Silver and gold tend to diffuse into each other, which can cause a plated piece to become dull or tarnished looking as the gold plating wears Layering the silver with copper first can create longerlasting Though hard gold contains less than 04% by weight of cobalt or nickel, the deposit hardness increases to over twice that of soft gold deposits Soft gold has a hardness of 70 to 80 kg mm2, while hard gold can have a hardness of between 170 and 200 kg mm2 on the Knoop hardness scale These hardness ratings have to do with the size of thePlating on Hard Gold vs Plating on Soft Gold Blog SPC

Selective gold plating, also called hard gold plating or gold plating, is electroplating a nickel coating and then a gold coating on the required PCB pads We call it selective because it happens before the solder mask printing and can apply to part of the PCB pads requiring itOn a circuit board, the PCB gold finger plating process is used after the solder mask and before the surface finish The plating process generally consists of the following steps: Nickel plating: Between three and six PCB Gold Fingers Specifications & What You Should
