Strange solder mask openings [message #165459] Thu, 14 April 2016 23:14 Go to next message

I have an Eagle 7.5 PCB that I am working on.  The solder mask layer on
top and bottom have some very strange line openings.  I do not know how
they got there, nor do I know how to remove them.  Please see the images
below.  They don't seem to be part of any component as if I move the
component, they are still there.  Can someone tell me how to remove
these?  Thank you!

To be honest, photos of your board are of no use whatever in answering
the question. We can't tell you what's wrong with your board. If you
showed us both the Eagle board editor (or posted your .brd file) and the
Gerber files you sent to the board house, then we would be able to see
whether the error is in your design, the CAM processing, or a mistake by
the board house. Without them we can say nothing.

If you see it in the Gerber data it is sure that there is something
drawn in the solder stop layer. If you can not delete them in the layout
editor in EAGLE it is obviously something that comes from a library.
What if you try to move on of the components in this area? Do the solder
stop wires belong to one of the parts there? If yes, you have to check
the package definition......

I finally gave up trying to figure out this problem.  So I simply used
Viewmate to edit the gerber files.  Thank you for your advise.
