While I am harvesting tin from s/n bridge - BGA type IC with usual methods aka heatgun or stanley knife I was thinking if there is not better one. I mean with heat gun or blade there will always stay some tin inside little cavities where solder balls are on IC. What if I will put them in HCl to dissolve all tin in solution. Then I can proceed as one will do trying to form tin crystals where cathode will be iron abut here is my problem - I do not know what should I use as anode.
I mean everytime when I saw this process for growing tin crystals anode was piece of tin but I plan to have tin already dissolved in HCl and harvest this one as crystals. What should I use as anode?
Or another question. If there is enough of tin dissolved in electrolyte and I will use another piece of tin as anode will dissolved tin deposit on anode first? If that is a case then I may dissolve as much as I can, let it deposit on cathode and then use electrolyte to dissolve more of solder from BGA chips and repeat this as many times as needed.
Am I right or it is not possible? What could be used as anode as alternative of tin to have just tin from electrolyte to deposit on cathode?
