The invention of mobile phone has developed to the present with the
increasing penetration rate, more and more people have mobile phones and
we can see that mobile phones have subverted this era. Naturally, it
will also drive many people to join the mobile phone repair industry.
1. Determine what
type of fault the phone belongs to and the possible fault range.
When repairing mobile phones, we should follow the some repair
operation rules. First connect the test instrument correctly, open the
test instrument and set it correctly, also preliminarily determine what
type of fault the phone belongs to and the possible fault range.
2. Check and understand the failure of the mobile phones
You
must carefully check and understand the failure of the mobile phones
before repairing. This step is the premise of precise and efficient
repair.
3. Do not perform repair operations under strong
magnetic fields and high voltages.
There are integrated chips of different manufacturers
and different models on the phone circuit board, as well as some new
components. And some weak current signals are transmitted on the chip
and important components.
Do not perform repair operations under strong
magnetic fields and high voltages, as high current shocks may damage
these components.
4. Know the performance of each cell phone chip and logical connection before repairing.
Since mobile phone is microelectronic
product and its internal integrated circuit structure is very precise,
this requires you to know the performance of each chip and component in
the mobile phone circuit board well before repairing it.
You also
need to know the logical connection between the chips in the mobile
phone circuit printed board. So you can operate it accurately to avoid
misjudgment, human failure and economic loss.
5. Ensure work platform is organized, and repair
tools are easy to reach.
When installing or disassembling mobile phone,
it must be operated in a certain order, and the chip components that
are picked and placed should also be arranged in a certain order to
avoid confusion or loss of any chips or components.
So it is necessary
to ensure that the work platform is organized, and the phone repair
tools are easy to reach. Pay attention to keep the mobile phone circuit board clean so as
not to affect the maintenance operation.
During the maintenance process,
it is also necessary to prevent all solder, tin beads, Jump wires, and conductive objects from falling into the circuit board to avoid other failures.
6. Use qualified and normal chips and components of the same
version.
When repairing some mobile phones that need to replace components, be
sure to use qualified and normal chips and components of the same
version, and avoid replacing chips of different versions.
Because
different manufacturers, different models, and different styles have
different version numbers. In order to ensure that the
communication quality of the repaired mobile phone does not decline.
It
is best not to use those chips and components with substandard technical
indicators, low quality, pirated, smuggled chips and components during
the maintenance process, so as to avoid more complicated failures.
7. Repair the mobile phone on the anti-static phone repair platform
Since the signal transmitted by the mobile phone is a little weak, the
static electricity attached to the mobile phone user or the operating
tool is enough to burn some components.
In order to reduce this loss, we
must repair the mobile phone on the anti-static phone repair platform. Also, ensure that the electrical shielding between the test instrument, maintenance personnel, and bench is well grounded.
