Rain forest Wind Win7 flagship system under the U-disk interface is broken how to solve

1. Disassembly

U disk package does not adopt a general screw fastening method, its key ring end using screws directly into the way, the exposed part is smooth surface, cannot use the common tool to unscrew the screw, therefore may use the small one word screwdriver to pry down the ring, or uses the method which the sharp nose pliers hard to unscrew the screw, but this way will tighten screws to twist the flower, Affect beautiful, as long as the two fixed screws down, and then the logo printed on the metal bar along the direction of the USB interface, will reveal the circuit board.

2, welding

MINI USB Interface on the circuit board welding a total of six solder joints, four USB data connection, two floor fixed. The main reason is that the mini floor of the fixed point of welding is not tight, loose after the mini connector is directly pushed into the resulting.

As long as the original position welded on the line, the two sides of the grounding point is easy to weld, but four data line contact is not easy to weld, you must use a pointed soldering iron. Must pay attention to soldering soldering iron must be good grounding, or flash chips or drive chips may be caused by static electricity and breakdown damage, there is a mini interface can not skew the position.

3, testing

Insert the Mini connector, and then connect with the PC, if the host can identify the U disk model and read out the data, it shows that the repair successful Oh, and then the original dismantling order back on the machine can be. If the two fastening screws are not very tight, easy to fall out of the words, you can use a little glue to strengthen it.
