Drawing notes:
1
Maintain a solder mask web
between pads when traces are
routed between the pads on the
same layer. The solder mask may
not encroach onto the pads within
the pad dimension shown.
2
VIAs not allowed on these pads.
VIA edges may be tangent to pad
edges as long as a solder mask
web between VIAs and pads is
maintained.
