PCB Assembly Considerations
1. Insert the sensor and all other electrical components
2. Bend the LED leads 90° and then insert the LED into
3. Insert the LED/clip assembly into PCB.
4. Wave solder the entire assembly in a no-wash solder
5. Place the lens onto the base plate.
6. Remove the protective kapton tape from optical aper-
7. Insert PCB assembly over the lens onto the base plate

process utilizing solder fixture. The solder fixture is
needed to protect the sensor during the solder process.
The fixture should be designed to expose the sensor
leads to solder while shielding the optical aperture
from direct solder contact. The solder fixture is also
used to set the reference height of the sensor to the
PCB top during wave soldering (Note: DO NOT remove
the kapton tape during wave soldering).

nants from entering the aperture. It is recommended
not to place the PCB facing up during the entire mouse
assembly process. The PCB should be held vertically for
the kapton removal process.

Design Considerations for Improving ESD Performance
The flange on the lens has been designed to increase
the creepage and clearance distance for electrostatic
discharge. The table below shows typical values assuming
base plate construction per the Avago supplied IGES file
and HDNS-2100 lens flange.
Typical Distance
Creepage
Clearance
For improved ESD performance, the lens flange can be
sealed (i.e. glued) to the base plate. Note that the lens
material is polycarbonate and therefore, cyanoacrylate
based adhesives or other adhesives that may damage the
lens should NOT be used.
