process utilizing solder fi xture. The solder fi xture
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 fi xture 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.
