Defect

Currently building The Abyss. Two little metal spots, not touching the tracks. Cleaned board with isopropyl alcohol and metal spots still there. Wondering if this is a defective board or it’s merely cosmetic.

It appears to be just a flaw in the solder mask.

The lower two spots are in the ground plane and shouldn't be an issue. You can verify that the trace isn't damaged by the upper spots by measuring continuity between these two points.

Thank you!

Shoot me an email if the trace is broken.
