Rain forest wood wind win7 Ultimate system under the u disk interface is broken how to solve

1. Disassembly

The U-disk package does not use the universal screw fastening method. The key ring end is screwed directly into the sleeve, and the exposed part is smooth. It cannot be unscrewed with ordinary tools. Screw, so you can use a small flat-blade screwdriver to smash the buckle, or use a needle-nosed pliers to harden the screw, but this way will twist the fastening screw, affecting the appearance, just screw the two fixing screws When you push down the metal strip printed with LOGO along the USB interface, the board will be exposed.

2, soldering

The MINI USB interface has six solder joints on the board, four USB data connections, and two ground plates. The reason for the falling off is mainly because the fixed point of the MINI grounding plate is not welded firmly, and the MINI connector is directly pushed in after being loosened.

As long as the original position is welded, the grounding points on both sides are easy to solder, but the four data line contacts are not easy to solder, and must be soldered with a pointed soldering iron. It must be noted that the soldering iron must be well grounded during soldering. Otherwise, the flash memory chip or the driver chip may be damaged by static electricity, and the position of the MINI interface may not be skewed.

3, detection

Insert the MINI cable, and then connect with the PC. If the host can recognize the U disk model and read the data smoothly, it means the repair is successful. It can be reversed in the original disassembly sequence. If the two fastening screws are not tight when they are replaced, it is easy to fall out, you can use the glue to strengthen it.
