Gold fingers are a vital part in PCB manufacturing. Sometime I feel a bit hard to identify whether the pcb supplier proceed the gold plating for fingers or not. But now I can use a good method: to see the Gerber files. If there is lead line in gold finger, it is gold plating as lead line is used for conductivity , and if no, it is ENIG Definitely. 

Refer to the following pictures:

Why have to judge this? Gold plating is much more expensive than immersion gold, and I don't want to spend unnecessary money.
