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.

base.
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).

aperture of the sensor. Care must be taken to keep
contaminants from entering the aperture. It is recom-
mended not to place the PCB facing up during the
entire mouse assembly process. The PCB should be
held vertically during the kapton removal process.

button presses must be minimized to maintain optical
alignment.
