Overview of Optical Mouse Sensor Assembly
Avago Technologies 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.
