Overview of Optical Mouse Sensor Assembly
NOTE: Pin 1 of optical mouse sensor should be inserted
into the reference point of mechanical cutouts.
Figures 3 and 4 are shown with HDNS-2100, HDNS-2200
and HLMP-ED80-xx000.
Avago Technologies provides an IGES file drawing de-
scribing the base plate molding features for lens and PCB
alignment.
The components shown in Figure 5 interlock as they are
mounted onto defined features on the base plate.
The ADNS-2620 sensor is designed for mounting on a
through hole PCB, looking down. There is an aperture
stop and features on the package that align to the lens.
The HDNS-2100 lens provides optics for the imaging of
the surface as well as illumination of the surface at the
optimum angle. Features on the lens align it to the sensor,
base plate, and clip with the LED. The lens also has a large
round flange to provide a long creepage path for any ESD
events that occur at the opening of the base plate.
The HDNS-2200 clip holds the LED in relation to the lens.
The LED’s leads must be formed first before inserting into
the clip. Then, both LED and clip is loaded on the PCB. The
clip interlocks the sensor to the lens, and through the lens
to the alignment features on the base plate.
The HLMP-ED80-xx000 is recommended for illumination.
If used with the bin table (as shown in Figure 8), sufficient
illumination can be guaranteed.
