Do-it-Yourself Repair FAQ u disk

Introduction of the system in the home of the U disk Tutorial article, about U disk fault Introduction to the majority of software. But in real life use, u disk hardware failures also occur frequently. For example, U disk interface is broken, this situation should do?

U disk using the mini USB cable and host for data transmission. Because the Mini in the U disk interface is a surface welding technology, not using through-hole welding, so often appear in the use of the process, because the user interface plug or force too much caused by the transfer of the mini connector inverted. When the mini USB interface is damaged, maintenance is also very simple, as long as you know the point of welding technology, the basis of the circuit can be.

The maintenance process is as follows:

1. Disassembly

U-Disk package does not adopt a general screw fastening method, its key ring with screws directly into the way, exposed part of the smooth surface, can not use the common tool to screw down. So when you want to take down the repair, you can use a small screwdriver will be deducted from the ring, or the use of sharp-nosed pliers hard screw down the way, but this way will tighten the screws screw flowers, affect the beautiful. As long as the two screws down, and then the logo of the metal strip 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.

Welding Needless to say, as long as the original position of welding 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, and the 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 succeeded.

4. End

And then in the original order of disassembly back on the machine can be. If the two fastening screws are not very tight, easy to fall out, you can use the glue to strengthen.

After reading the steps described in the tutorial, some users may be afraid of the dismantling operation. In fact, there is no need, today's electronic equipment, including U disk, the design of its internal components are relatively perfect, and will not easily be destroyed by their own dismantling. If you do the necessary preparation, you can start the work.
