Copper wires with 0.1 mm diameter with a layer of isolation lacquer.Hot air gun station (for example – Lukey 702).USB soldering iron with a very thin solder tip.A good optic microscope with x2, x4, x8 zoom.For example, you can buy a couple of them just to test your skills of preparing and soldering.īelow you can find the list of necessary equipment: If you never tried to solder monolithic devices before, it’s better to try your skill on some donor devices where data is not important. In such cases, the full process of recovery was very simple – we just unsoldered the memory chip, read it in PC-3000 Flash, and made the same preparation as with common USB Flash drives.īut what should we do if our Memory Card, or UFD device is based on monolithic architecture? How can we get access to a NAND memory chip and read data from it?īasically, in this case we should try to find a special technological pinout on the bottom side of our monolithic device by erasing the ceramic layer of coating.īefore you start dealing with monolithic recovery, we should warn you that the complete process of monolithic device soldering is complicated and requires good soldering skills and special equipment. Until recently, all memory cards like SD, Sony MemoryStick, MMC and others, contained a very simple “classic” structure with separated parts – a controller, a PCB and a NAND memory chip in the TSOP-48 or LGA-52 package. Nowadays a lot of modern NAND flash devices use a new type of architecture, where the interface, the controller and memory chips are integrated into one common ceramic layer.
