I am working on a small profile boost driver based on LM3410. I got most of the layout done, but I am trying to make a rim of stop mask that will expose the part of the GND plane to contact the host. (I attach a photo below to show the rim i was planning to do.) But I couldn't figure it out how to do it. All i can find is how to make via without stop mask. Hopefully someone with design experience can help me out!!:thanks:
