Trace width costs
Given the .75mm ball spacing
Gold Phoenix for example charges
155 Sq inch
2 layer base cost $99
6mil/5mil/4mil trace width/ clearance(2layers) $20/$40/$60
4 layer base cost $330
6mil/5mil/4mil trace width/ clearance(4layers) $40/$80/$200
If our breakout board was 4 sq inches for example that would yield about 38 peices so below is the cost per piece for reference
Trace widths
8 6 5 4
2 layer 2.55 3.07 3.58 4.10
4 layer 8.51 9.54 10.58 13.67
Since I have ordered with them before I might be ablet to get another 10% off
