Thanks for the quick reply. Just a note on all these boards, they came from an industrial setup not a computer based setup. I do not know if that makes a difference as the gold platting is thicker.

Thanks again.

It doesn’t. I will hesitantly say the larger board may get a higher rate. But the rest of the etch are peripheral.
They look like interface boards. Such as the dgae-1 375 comes up as a flow controll interface. I’ve sent boards like this to boardsort before. I had a YouTube scrapper refine one like the big one for me and he came up with $1.80 in gold after 2 months of bath. He didn’t say as much but I’m fairly sure he spent more on the acids than he got for the gold.

The boards were control boards for old machine equipment but the layout was bad so they scrapped them and were sitting around for 25 years.

Thanks again
