Note: It is not possible to disassemble the power actuator without damaging it. The power actu­ator is the same material as B-cover.
Note: If a new B-cover is used, a torque setting of 28Ncm and speed in the range of 400 - 600 rpm is required to cut the new thread.

Dome Sheet Placement

Since the dome sheet has to be removed before every soldering process a new dome sheet needs to be placed between the PWM and light guide.
Note: In some regions the light guide assembly (which includes the ligh t guide, the meta l frame and the domesheet) will be replaced as one part (this is the preferred procedure). The descrip­tion below is needed, when the domesheet needs to be replaced separately, which is not the preferred procedure.

Cleaning

The PWB needs to be cleaned and all remaining material from the old dome sheet needs to be removed. In some regions there is the possibility to exchange the dome sheet separately (no t together with the light guide assembly), then the light guide needs to be cleaned as well.

Placing the dome sheet to the light guide

The dome sheet is delivered on transparency foil. First step is to remove th e dome sheet from the foil, where you need to ensure that the complete dome sheet is lifted and the protecting foil on the other side of the dome sheet still sticks on the dome sheet. Please see picture below:
Protecting foil will stick on dome sheet
All dome sheet parts are lifted. (Nothing sticks on the bottom foil.)

Place the dome sheet onto the cleaned light guide and press them firmly together.
Take care, that the holes of the domesheet align exactly with the holes on the light-guide.

Placing the light guide assembly onto the PWB

In some regions there is the possibility to order the light guide assembly including the dome sheet. In any case the protecting foil needs to be carefully removed from the dome sheet.
Then place the assembly to the PWB and press it firmly together.
Note: It is very important to press the light guide assembly and the PWB properly together at any point. If some points are not pressed properly together dust and humidity will sneak between PWB and dome sheet and will cause corrosion, which lead usability problems and to a defect which might lead to a total loss of the phone.
Now you can be continue with the assembly procedure.
