General
- How to use this document
Place the schematics behind this manual.
Now you are able to follow these specifictions with graphical layouts and it is easier for you to find the components and
measuring points.
- General handling
All screws must be screwed with a torque of 16Ncm. If a higher torque is used, the cover might be damaged.
If it is necessary to make a backup, be sure that the data are ok, otherwise it is possible that the corrupt files are responsible for
the same faults as before reinstalling the backup.
- µBGA components and broken balls
Special attention to µBGA components:
All µBGA´s with the exception of MADLINDA D300 are replaceable and must be renewed after removing. Reflow by hot air fan is
not allowed.
Check soldering points, remove oxidated solderings (broken balls) carefully by enclosing a few new solders before placing new
components. The only allowed way to change µBGA components is to use µBGA rework maschines, approved from NMP (e.g.
ZEVAC/ OK International). Only use recommended Fluxtype and an appropriate amount of it.
- Component charactaristics
Some components contain important data.
Several described steps are only practicable if you are able to reflash/ realign the Communicator 9210 and/ or rewrite IMEI/
SIMlock in certain cases. Please pay attention to separate notes.
- Realign after repair
Characteristics of replacement parts are different.
To prevent additional faults after repair (RX quality, TX power etc.) it is necessary to retune phone values.
