Overview of Optical Mouse Sensor Assembly

Pixart provides an IGES file drawing describing the base plate molding features for lens and PCB

alignment. The sensor is designed for mounting on a through-hole PCB. There is an aperture stop and features

on the package that align to the lens. The lens provides optics for the imaging of the surface as well as the

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 clip holds the LED in relation to the lens. The LED must be inserted into the clip and the LED’s leads formed

prior to loading on the PCB.
