Hi,
Most likely my error someplace, brand new to Eagle CAD. Anyway, my
question is: Is tStop layer invisible by default? Reason for this
question: I was down to zero DRC errors on my first small board layout
with Eagle, then I notice part of the perimeter (layer 20) had vanished
on my layout. So, I turned off view of all layers, then turned on just
layer 20 so I could redraw the border outline. Fine, done with that,
turn on ALL layers and ran DRC. Now have about 30 errors re tStop layer.
How is it possible to not see this before? Just for fun, I turned off
tStop layer and ran DRC again. No errors! What the heck... can anyone
shed some light on this, is there something I need to fix? By the way, I
did 99% of this layout with original default design rules, then found
that SunStone had a .DRU file for Eagle, so I loaded that. Still did not
see errors before turning on ALL layers. Should I be concerned about
these errors I almost did not notice before ordering boards? I made
Gerber files & looked at them with GerbV, they look fine to my
eyeball...but i don't perceive 3mil objects all that well! That seems to
be the top solder mask min/max in the SunStone rules.
Thanks for any enlightenment,
Bill
