PCB Assembly Considerations
1. Insert the sensor and all other electrical components
2. Bend the LED leads 90 degrees and then insert the
3. Insert the LED/clip assembly into PCB.
4. Wave solder the entire assembly in a no-wash solder
5. Place the lens onto the base plate.
6. Remove the protective Kapton tape from optical
7. Insert PCB assembly over the lens onto base plate

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.

button presses must be minimized to maintain optical
alignment.
