I don't remove any transistors, IC chips or flatpacks because it can devalue the boards.
Cool. Guess it'd be good to look in to how much value boards lose by taking them off. The buyer Mechanic shared link for pays .90 a # for the transistors. I've probably git a couple hundred I already smashed the black stuff off of to get to the copper inside. Weight from them adds up quick
