OPTICAL NAVIGATION CENTER
Insert the sensor and all other electrical components
into the application PCB (main PCB board and VCSEL
PCB board).
Wave-solder the entire assembly in a no-wash
solder process utilizing a 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.
Place the lens onto the base plate.
Remove the protective kapton tape from the optical
aperture of the sensor. Care must be taken to keep
contaminants from entering the aperture.
Insert the PCB assembly over the lens onto the base
plate. The sensor aperture ring should self-align to the
lens. The optical position reference for the PCB is set
by the base plate and lens. Note that the PCB motion
due to button presses must be minimized to maintain
optical alignment.
Remove the protective cap from the VCSEL.

Design Considerations for Improving ESD Performance
For improved electrostatic discharge performance, typi-
cal creepage and clearance distance are shown in the
table below. Assumption: base plate construction as per
the Avago Technologies supplied IGES file and ADNS-
6130-001 trim lens (or ADNS-6120 round lens).

Creepage
Clearance
Note that the lens material is polycarbonate and therefore,
cyanoacrylate based adhesives or other adhesives that may damage
the lens should NOT be used.

Insert the VCSEL assembly into the lens.
Slide the clip in place until it latches. This locks the
VCSEL and lens together.
Tune the laser output power from the VCSEL to meet
the Eye Safe Class I Standard as detailed in the LASER
Power Adjustment Procedure.

to the correct vertical height.
