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.

keep 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.
