PCB Assembly Considerations
HLMP-ED80-XX000 (LED)
ADNS-2220 (Clip)
ADNS-3060 (Sensor)
Customer supplied PCB
ADNS-2120 (Lens)
Customer supplied base
plate with recommended
alignment features per
IGES drawing.

1. Insert the sensor and all
other electrical components
into PCB.
2. Insert the LED into the
assembly clip and bend the
leads 90 degrees.
3. Insert the LED/clip assembly
into PCB.
4. Wave Solder the entire
assembly in a no-wash
solder process utilizing
solder fixture. The solder
fixture is needed to protect
the sensor during the solder
process. It also sets the
correct sensor-to -PCB
distance as the lead
shoulders do not normally
rest on the PCB surface.
The fixture should be
designed to expose the
sensor leads to solder while
shielding the optical
aperture from direct solder
contact.
5. Place the lens onto the base
plate.
6. Remove the protective
kapton tape from optical
aperture of the sensor. Care
must be taken to keep
contaminants from entering
6
the aperture. During mouse
assembly process, it is
recommended that the PCB
is held vertically when
kapton tapes are being
removed.
7. Insert PCB assembly over
the lens onto the base plate
aligning post to retain PCB
assembly. The sensor
aperture ring should self-
align to the lens.
8. The optical position
reference for the PCB is set
by the base plate and lens.
Note that the PCB motion
due to button presses must
be minimized to maintain
optical alignment.
9. Install mouse top case.
There MUST be a feature in
the top case to press down
