Uniwell strives to be an environmentally friendly PCB manufacturer. we recent advances and improvements to the surface finishes used on printed circuit boards. ENIG has been a popular surface finish because of its very flat surface, ability to handle multiple reflow cycles and good shelf life. However, there can be challenges with nickel corrosion that can cause what is called “Black Pad”. Black pad occurs when the nickel under the gold plating corrodes excessively and the component soldered to that pad loses connectivity. ENIG can be challenging for some printed circuit board manufacturers, as black pad can be difficult to detect when examining the surface finish since the gold completely covers the final surface, from below PCB flow chart, you can know about the important of the surface finishes It is a very flat surface that is ideal for Surface Mount Devices (SMDs) and Ball Grid Arrays (BGAs).  Gold is a great conductor of electricity.  Many contract assemblers prefer this finish.
