Abstract:
1. A chip-on-board (COB) module of an optical mouse for being mounted on a mouse base, comprising: a module printed circuit board; a chip including a sensor circuit, soldered in the form of a COB structure onto the module printed circuit board; a light source device soldered onto the module printed circuit board; a lens aligned with the chip and the light source device; an enclosure separate and distinct from the mouse base holding the lens therein and engaged with the module printed circuit board, wherein the COB module is for being mounted on the mouse base and light generated from the light source device is able to pass through the enclosure; and an opaque photo shield having two openings aligned with the chip including the sensor circuit and the light source devices, respectively, wherein a controller circuit is integrated on the chip or on another chip soldered onto the module printed circuit board, wherein the enclosure has a sidewall to form a space with a top opening to accommodate the chip, the light source, the opaque photo shield, and the lens, wherein the top opening is covered by the module printed circuit board, and wherein the sensor circuit and the light source device are soldered onto a same side of the module printed circuit board and are inside the space formed by the enclosure.
