4. 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 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.

Following General Service Bulletins have to be followed:

SB-055 Common notice for good ventilation
SB-089: Don’t try to repair prototypes (indicated on Typelabel).
SB-107: Be sure that you have minimum hardware requirements in place.
SB-115: Handling of liquid damages.
SB-121: If one of your service tools cause malfunction, return the defective part.

SB-122: Soldering with manual hot air gun is totally forbidden because of the very sensitive

µBGA components and µVia technology.

SB-124 Service Policy for packaging serviced products
SB-131: Check these guidelines when refurbishing products.
SB-132: You need a Golden Phone for inspecting your measuring equipment.

Please check Partner Websites (PWS) for latest news and files on a regular basis.

Legend for Quick Trouble Shooter:

This legend is valid for all parts of the
