I have recently acquired some different PCBs and wanted to arm myself with knowledge to avoid getting bested at the recycle center. What are the generalities? I know brown is always low grade, but if green, is more populated better? are there other ways to tell if Med or high? Below are pictures. I have numbered each pic to facilitate the references in replies.
