The pen drive is the standard usb interface with added to it
a small memory chip. All usb pen drives are made by the same principle that the
communication is based on usb signals.
When we brake the usb dongle usually the crack occurs when
the metal plug is connected to the PCB inside the device. The inside structure
of this device is similar and varies just the how manufacturer implements the
wiering or in other words the tracks on the PCB.
In every drive we will find the two tracks that are in the
middle of the plug. They are data + and data – tracks. The other two are power
as +5 V and the ground.
To repair the broken we just need to connct again the broken
tracks together and copy the data as soon as possible. The drive after we do
this would not be usable just because the wires can broke again best is just to
bin it.
Here is the image that show the internal structure of the
pen drive.
We need to connect together wery small four wires that are
on the so called PCB (printed cirquit board). Ia am doing it with very small
soldering iron. And this is not so easy to do so if you do it first better is
to practice this on something else.
You will need also a flux and tip dip to clean the soldering
iron tip. Also the solder is necessary.
To better understand what to connect here is more images
showing the connections.
