BGA escape routing can be routed with 4-mils width and 4-mils spacing, as long as the escape nets are less than 1 inch long, to allow 2 traces fit between vias. After signals escape the BGA field, trace widths can be widened to achieve the desired impedance and spacing.
All single-ended 50-Ω signal must have a minimum spacing of 10mils relative to other signals. Other special trace spacing requirements are listed in Table 10-7.
