5. GENERAL REPAIR INFORMATION
In this section you will get some general hints how to carry out repairs:
o
Before starting the repair you must take care of ESD precautions like being in your
ESD-area and connecting your wristband.
o
Use gloves to avoid corrosion and fingerprints.
o
Protect windows and displays with a foil to avoid dust and scratches.
o
When cleaning the pads you have to use a soft cloth and isopropanol. It is not
allowed to use a glass fiber pencil because it scratches the surface and will lead
later on to corrosion.
o
Soldering with
manual hot air gun
is totally forbidden because of the very
sensitive µBGA components and µVia technology. Please check general Service
Bulletin-122.
o
Mechanical parts, which didn’t repair the failure, can be reused, if they are not
soldered.
o
Use always original Nokia parts or accessories.
o
Meet the torque requirements when assembling the unit (see also the document
“torques for transceiver assembly” on Partner Websites).
o
Always use your own equipment for testing where you are sure that it works. E.g.
if the customer complains about charger function, please test the phone with your
own charger to be sure if phone or charger causes the malfunction.
o
The bottom side of a module is the side where the part no. of the pcb is seen.
o
Please check Partner Websites (PWS) for latest news and files on a regular
basis.
