have you try to change the stencil apertures to another figure like the one that look like a baseball home? I was having that problem and some solder beads and with that I was able to decrease the tombstones

Hi, follow up, Thanks to everyone that responded. We finished the build, the sun burst thru the clouds and the birds sang. Well that was a slight exageration. Sorry for lack of detail on the original post, I was frazzled. Since the 0201's were p
