Final finishes are key to the protection of exposed circuitry and the assembly of the components to the printed circuit board. At one time the most common finish was solder. Today there are well over a dozen different finishes, each with their own niche. The change in finishes was brought on by environmental concerns and an increase in circuit densities. Some of most widely used finishes are Hot Air Solder Leveling (HASL), HASL Lead free, Electroless Nickel Immersion Gold (ENIG), Immersion Tin and Organic coatings.

To get the legend that is often printed on the PCBs and ink-jet printer silkscreen the board.

This legend usually contains the component designators, switch settings, and other indications helpful in assembling, testing and servicing the printed circuit board.
