Is there any difference between a gold coated pad and a gold pad? I have been ordering boards from OSH park, they are really good quality, I'm just wondering what benefits this has over silver or bare copper pads.
What are the benefits of usign a gold coated pad? I do know it must have better conductivity and proably better or lower resistance but, does coating really achieve all this? doesn't the material below the coating affect the conductive properties of the tracks?
