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.
