Hi guys, I'm new here. I did some searching but there didn't seem to be a thread that talked about removing low value stuff from PCBs. Where I live there aren't really anyone who buys whole PCBs so I'm interested in depopulating everything worth even a tiny amount. Besides the obvious like small transformers and coils, tantalum caps, MLCCs, etc, what's worth removing? I've heard aluminum electrolytic caps are worth aluminum breakage, and the ceramic caps are good to take. What about common resistors and diodes? Or poly caps? Basically, what should I be leaving on the board that no one's going to buy for scrap?

Thanks
