3. 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 arm wrist.
o
Use gloves to avoid corrosion and fingerprints.
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
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
Don’t’ try to repair liquid damages.
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 on a regular basis
