I bet at the factory they had a couple of QC failures and identified the cause as contact plating issues. So they just sand the top of the board now because it made one work. Never trust a QC engineer. They’re almost as bad as software engineers.

Either way screw that - they’re added to my vendor shitlist now. Nothing should be shipping like that.

I believe the picture Kartika linked in their last post is simply an enlargement of the original one that Dave linked, with their (Kartika's) opinion as to the cause.

It is not good to see those scrubbing marks though, very disappointing from a manufacturer of Brymen's reputation.

Is that PCB pothole on your multimeter? I don't see it in your first pics so I'm a bit confused.

this is like cramp processing ... it worries me, and I only hope this is a mistake ...

Looking at the board, this pad is indeed the one used to select the high speed clamp when in ohms.   Looks like a 1.3K PTC and a 1K, typical.   I took some decent before pictures of this area and will attempt to reproduce the picture shown.
