- Keep the copper away from the very edge of the board
- Copper to the edge or of the board can cause shorts along the side of the board
- copper layer could peel up
- increases the chance of corrosion on the exposed copper
- Make sure there are no right angles in poly pours or solid regions - could act as antenna otherwise.
Board - Mounting
- All mounting holes are kept away from the edge of the board
- There is adequate support for all the heavy components and connector plugs
- Large boards should have more than 4 mounting points
- Make sure that edge mounting holes are about 2.7mm radius an are at least 3mm away from each edge. Lock these components after placement.
- Make sure there is a keepout/polygon cutout around mounting holes -> cannot be on the keepout layer → has to be copied on the bottom and top layers
