Overview of Optical Mouse Sensor Assembly

PixArt Imaging provides an IGES file drawing de-

scribing the base plate molding features for lens and

PCB alignment.

The components interlock as they are mounted onto

defined features on the base plate.

The ADNS-3530 sensor is designed for surface mounting

on a PCB, looking down. There is an aperture stop and

features on the package that align to the lens.

The ADNS-3150-001 lens provides optics for the imag-

ing of the surface as well as illumination of the surface

at the optimum angle. Features on the lens align it to

the sensor and base plate.
