To Disassemble the ADNK-5703 Unit
The ADNK-5703 comprises of the plastic mouse casing,
printed circuit board (PCB), lens, buttons, and USB cable.
(See Figure 3) Unscrewing the one screw located at the
base of the unit can open the ADNK-5703 unit. Lifting and
pulling the PCB out of the base plate can further disas-
semble the mouse unit.
Caution: The lens is not permanently attached to the sensor and will
drop out of the assembly.

XXXX optical mouse sensor.
While reassembling the components, please make sure
that the Z height (Distance from lens reference plane to
surface) is valid. The Z-height is from 2.3 to 2.5mm with a
nominal of 2.4mm. Refer to Figure 4.

into a mouse with shielded cable and following Avago
Technologies recommendations.
x
UL flammability level UL94 V-0.
x
Provides sufficient ESD creepage/clearance distance
to avoid discharge up to 15kV when assembled with
round lens into a mouse according to usage instructions
above.
Sensor
The sensor technical information is contained in the
ADNS-5700-XXXX Data Sheet.
Lens
The lens technical information is contained in the ADNS-
5100 Data Sheet. The flange on the standard ADNS-5100
lens is for ESD protection.

The LED technical information is contained in the HLMP-
ED80-XX000 Data.
Base Plate Feature – 3D Model IGES Files
The IGES file on the CD-ROM provides recommended
base plate molding features to ensure optical alignment.
This includes PCB assembly diagrams like solder fixture in
assembly and exploded view, as well as solder plate. See
Appendix D for details.
Reference Design Documentation – Gerber File
The Gerber File presents detailed schematics used in
ADNK-5703 in PCB layout form. See Appendix C for more
details.
