anachronism said:The components under the black "blobs" are more likely to contain gold than the traces on that type of board. Soaking the boards in NaOH is one way to remove the green solder mask but I would recommend that you look up the dangers of working with that stuff before you do it and ensure that you follow the relevant safety precautions because it is extremely unforgiving if you get it in your eyes.

kernels said:For learning, you are far better to go on ebay and spend too much money for some RAM or trimmed fingers. It doesn't matter if you pay too much, because at least you will end up with enough gold that you can actually see it drop out of solution and melt it into a (small) button.
By processing a few of those LCD boards, you may not even have enough gold to see it drop out of solution and almost certainly not enough to make melting it worthwhile.
Same thing basically applies to those bond-wire-blobs. You want at least 100g or so of them before you are likely to end up with around 0.1g to 0.3g of gold.
