PCB Plating: The Complete Guide of Plating Techniques in

This surface PCB plating process refers to the creation of a thin silver layer over a copper layer. In other words, it involves the immersion of copper objects into a silver ion solution. So, many engineers in the electronics sector use the immersion silver plating process.

Plating Thickness And Surface Hardness Measurement

Electroplating is inexpensive, reliable, efficient, and applicable to a wide variety of shapes and sizes. However, traditional electroplating technologies often result in uneven surface finishes, and have inherent pollution problems. Electroless plating has increased in

Immersion gold or electroless gold plating on silicon

Immersion gold plating works by a replacement reaction where the substrate metal dissolves into solution in exchange for metal from the plating solution plating out onto the substrate. The familiar copper plating layer that chemistry students see deposit onto iron nails when they are placed in copper sulphate is an immersion plating; as is the deposition of silver onto copper when it's

Electroless nickel plating – everything you need to know

Electroless Nickel Plating (ENP) is the deposit of a nickel-alloy coating by chemical reduction – without the electric current that's used in electroplating processes. The majority of ENP for engineering purposes is a nickel phosphorus deposit containing 2 to 14% phosphorus.
