#167666 - Not such a good idea Responding to: ???'s previous message |

[...] I suggest that you make the top and bottom layers your power/ground planes [...] While that may work for an all through-hole board, for an SMT board like Lucas' it's a definite no-no. For a ground plane to work effectively, it must be as uninterrupted as possible and there is just no way to achieve that on the component layer of an SMT board. Also, keep your signal traces away from the edges of the planes (fringing effects). That is sound advice :-). |
