Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics.

The main components of the wire-to-board terminal block can be divided into three parts: hardware, plastic case and accessories, of which the first two parts are more important. The importance of plastic case need not be overstated. Parameters such as impact resistance and flame retardant are essential, but when it comes to electrical performance, the responsibility is not to be a conductive part. Conductive parts are responsible for conducting signals. The selection of materials and electroplating directly affect the conductivity of the terminals. Which material is better? Most terminal products use alloy copper electroplating nickel as conductive parts. Pure copper has excellent electrical conductivity, but as a conductive part, it needs a certain hardness while having good electrical conductivity, so a small part of other metal materials are added to form copper alloy to meet these two needs.
