3 General Information

The S6 is the first model of a whole new handset generation in 3 Volt technology.
It comes either as a GSM or a PCN version.

4 Mechanical Concept

Note: All part numbers refer to mechanical drawing in section 4.1!
The S6 consists of two boards, the RF & Control module (1010) and the user
interface (1020).
The connection between those two boards is not made by a normal connector with
plug-in contacts, but by a special interconnector (1090) embedded into a shielding
frame (1060). This interconnector is upholding the connection through the pressure
implied on it by the housing.
Be careful when assembling the interconnector. Avoid any kind of dust or dirt
because it will affect the contacts of the interconnector.
The only removable part on the user interface is the ringer gasket (1080) which is
needed to increase the ringer volume.
Furthermore there is a RF-plug on the user interface which has to be plugged into the
appropriate connector on the RF & control module. This conection is very essential
because it is the RF signal from / to the internal antenna.
The shielding is done by the lower case shell (1050) which is covered with a
conductive material, so no additional shielding screen is necessary.
The antenna (1130) is directly screwed into the lower case shell.
The keypad (1030), the loudspeaker (1120), the microphone (1110) and the dust
protection frame (1210) are mounted into the upper case shell (1040). Make sure that
the microphone contacts are properly bent up when mounting.
When turning in the screws (1140, 1145 and 1150) make sure that the right torque is
used (25 Ncm), because this will have an effect on the contacts of the interconnector.
Note: Make sure that you mount the right antenna, the GSM antenna has two
stripes, the PCN antenna only has one!
