jonisonvespa:
im building something and want to try a resignator and crystal in the same circuit, ive added a pad so i can fit both obviously not at the same time, just wondering if the surface mount pad will effect the resignator/ timing because of the pads?
In principle, yes (especially if there is a ground plane on the other side of the board); but the effect will be very small, so no need to worry about it.
