GENERAL
-How to use this document
Put the colored schematics behind this manual.
Now you are able to follow these specifications with graphical layouts and it is easier for you to find the
components and measuring points.
-Component characteristics:
Some components contain important data.
Several described steps are only practicable if you are able to reflash/ realign the phone and/or rewrite
IMEI/SIMlock in certain cases. Please pay attention to separate notes.
-Broken balls, µBGA
All replaceable µBGA-components must be renewed after removing.
Reflow with hot air fan is strictly forbidden!
Check soldering points, remove oxidated solderings (broken balls) carefully by enclosing few new solder
before placing new components.
µBGA must be soldered only with NMP approved µBGA-rework machines (e.g. Zevac/OK International).
Only use recommended fluxtype and an appropriate amount of it.
-PCB handling & cleaning
To avoid damages of PCB and/or components through electrostatic discharging, handle the module in
ESD-suitable cases only. Always wear ESD-bracelets, which must be connected to earth bonding point.
Do not make any loose wiring connections or do some other unqualified rework anywhere.
For cleaning only use appropriate materials,
do not use scratching or rubbing tools.
Because of organic surface protection (OSP) cleaning must only be done with a lint-free cloth, which may
be moistened with DI-water. IPA or other solvent like ethanol should only be used to clean gold pads for
spring contacts without affecting the surrounding copper layers.
-Realign after repair
Characteristics of replacement parts are different.
To prevent additional faults after repair (eg. low standby time, loosing network etc.) it is necessary to retune
phone values after repair. But never try to cover a fault by tuning.

INTRODUCTION
IMPORTANT:
This document is intended for use by authorized NOKIA Service Centers only.
The purpose of this document is to provide some further service information for NOKIA 3310 / 3330/3410 phones.
It contains a lot of collected tips and hints to find failures and repair solutions easily.
It also will give support to the inexperienced technicians.
Saving process time and improving the repair quality is the aim of using this document.
We have built it up based on fault symptoms (listed in "Contents") followed by detailed description for further analysis.
It is to be used additionally to the service manual and other service information, e.g. Service Bulletins.
For that reason it does not contain any circuit descriptions or schematics.
All measurements are made by using following equipment:
Nokia repair SW
DLL version
Nokia module jig
Digital multimeter
Oscilloscope
Spectrum Analyzer
RF-Generator /
GSM Tester
While every endeavour has been made to ensure the accuracy of this document, some errors may exist. If the reader finds any
