PCB Assembly Considerations

1. Insert the sensor and all other electrical components

into PCB.

2. Bend the LED leads 90° and then insert the LED into

the assembly clip until the snap feature locks the LED

base.

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. 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).

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 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.

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 onto the clip to ensure all com-

ponents are interlocked to the correct vertical height.
