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. 29 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. 42 43
