before routing
- make sure SMD pads do not fall into the route path. would like 5 mils from the board edge.
- make sure that edge pads and mouse bites are not adjacent.
- use better DFM to verify there are no stubs
- make sure that mounting holes to not have traces routed to them. possibly at a note that holes with targets are non-plated
- turn on layer 8, the assembly, and mask layers and remove unwanted text.
- for the board outline, use 2 mill on the board layer
- for route and retain use the title layer (60 mills wide)
- typically place 5 mounting holes of 10/20 spaced at 20 mills.
during panalization
- shrink mounting hole pads to just larger than the hole
- view assembly and mask layers; verify there is no small text
- look at silk layers for small text
README FILE
* vias that connect top-bottom side traces must be fully masked. if necessary, please run the mask process twice to make sure there is no exposed copper. * Holes with targets are non-plated mounting holes.
