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.

contaminants from entering the aperture. Recommend
not to place the PCB facing up during the entire mouse
assembly process. Recommend to hold the PCB first
vertically for the Kapton removal process.
