I have thousands upon thousands of these. They are difficult to isolate the board and have been having problems with aqua rigia being really dirty. I am wondering if it is worth it to try and get the gold out of them. Does anyone have an idea if it is worth the time and effort. They are chips from an old digital billboard. These are specifically the chip for the actual LED lights.
