Put them on ebay at least you will earn something.
In the forum there will be someone that can help you.
I wish it because this posts are very interesting.
I am going to look at the chip under a microscope, maybe only bond wires broke
re-reading this makes me feel rather silly (at my witch hunt tactics and short temper) but I am still proud of even attempting such a task... david vs goliath
nothing a bit of white fuming nitric acid cannot decapsulate. its quite easy to make a few ml of 90%+ using drain cleaner and food preservatives with ghetto distillation techniques, or so it seems. I think you only need a drop or three. so long your starting reactants are devoid of water then the nitric acid produced is of much higher purity then the commonly available 70% NA.
I am defiantly NOT Paying for commercially made WFNA though. those prices are scandalous. not for this "corpse"
all those people buying expensive nitric acid for decapsulating chips are probably being ripped off. you can re-distill it over dry sulfuric acid several times to increase the purity to anhydrous, especially for the drop or two required for chip die extraction,
all yoou need is a test tube and a candle. you mix the ingredients and heat to start the reaction, then you insert a clean but cold nitric acid resistant object into the test tube (such as a narrower test tube or glass rod that was stored in a freezer), but not as to touch the liquid. the pure nitric acid vapors will condense on the cooled object, which you then pull out of the test tube and swab onto your chip.
also this should be done outside with a fan blowing over your work bench so you do not get any nitric acid fumes in your lungs. from what I understand it will choke yoou, burn your lungs and give you cancer. treat it like plutonium.
