Having silk screen ink on the surface mount pads is ok if you don't
intend on having solder joints on those pads! The silk screen ink will
interfere the formation of the solder joint and give you questionable
solder joint reproducibility.

Recently I have seen PC boards with silk screen ink on surface mount
pads. Is any of this allowed? Looking at the PC board IPC standards, I
don't see this subject addressed. May I have some guidance?
