| 23 | Board dimensions/outline included as zero width trace in silkscreen layer |
| 24 | for reference. Board is made from 0.062" FR4 with 1oz copper on all |
| 25 | layers. Minimum trace/space is 6/6 mils. |
| 26 | |
| 27 | NOTE: Board contains 3 plated slots, each slot is marked at the two ends |
| 28 | and center with 0.041" drills. |

| 30 | Board layers stacked as follows: |
| 31 | |
| 32 | Top Silkscreen (Black) |
| 33 | Top Soldermask (White) |
| 34 | Top Copper (1oz) |
| 35 | FR4 (62 mil) |
| 36 | Bottom Copper (1oz) |
| 37 | Bottom Soldermask (White) |
| 38 | Bottom Silkscreen (Black) |
| 39 | |
| 40 | Process the silkscreen layer against the soldermask layer to prevent |
| 41 | overlapping silkscreen on the pads through mask openings. |
