WebENIG is quickly becoming the most popular surface finish in the industry. It’s a double layer metallic coating, with nickel acting as both a barrier to the copper and a surface to which components are soldered. A layer of gold protects the nickel during storage. WebThe surface finish has two essential functions: –To protect the exposed copper circuitry. –To provide a solderable surface when assembling (soldering) the components to the PCB. Most surface finishes are considered SMOBC (Solder Mask Over Bare Copper). 3 SURFACE FINISHES Factors When Choosing Finish: –Cost –RoHS \ WEEE \ ELV
