Ремонт L3. Гнилая. Порваны пятаки

L3+ Chips (BM1485) - http://www.elenblog.ru/BM1485 L3+ Stencil - http://www.elenblog.ru/Stencil_BM1485 Good Rolling Paste - http://www.elenblog.ru/Mechanic_paste... Flux - Original Glue - http://www.elenblog.ru/Glue_hash_board I don't know the details, but it looks like the ASIC was bought from China. Naturally, they bought it as a working board, but in fact, they received drivers. There are traces of diagnostics on the board, and judging by the fact that three chips needed to be replaced, they decided not to bother with repairs and just shove it into the ASIC for the happy buyer. As it turns out, the board had been operating in a humid climate for quite a while. Probably in China, on the bank of a river near a hydroelectric power station, since part of the board was rotted by water (moisture). If you buy used ASICs (and as far as I understand, that's the only kind now), open and inspect each board; everything should be clean and looking good. If there's rot, it's best not to buy it. The board can die at any moment.
