GENERAL
Put the QUICK REPAIR layouts 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.
-How to use this document
-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.
-Underfills, broken balls, µBGA
It is not possible to change underfilled components. The trial will damage PCB surely. All replaceable
µBGA-components must be renewed after removing. Reflow is not allowed.
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).
Use only recommended Fluxtype and an appropriate amount of it.
-PCB handling & cleaning
Only use appropriate cleaning materials, don`t use scratching or rubbing tools. Clean PCB carefully after
every rework and take great pains over the keyboard area. Don´t make any loose wiring connections
anywhere.
If it is necessary to clean the PCB, please pay attention to the following: Because of organic surface
protection (OSP), cleaning must only be done with a lint-free cloth which may be moisten 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.
If it is necessary to change any item located under the metal shields, remove the shield first, don´t cut
partially or bend it.
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.
-Realign after repair
