Abstract:
1. A method of manufacturing an optical module, the method comprising: providing a conductive lead frame having an arm portion formed therein, the arm portion having an aperture formed therethrough; attaching an optical sensor chip to the lead frame; attaching a light source to the lead frame spaced from the optical sensor chip; bending the arm portion of the lead frame to position the aperture in correspondence with a light-sensing area of the optical sensor chip; and encapsulating both the light source and the optical sensor chip and bent arm portion to form a package assembly, the encapsulation step including forming a first lens on the light source and forming a second lens in correspondence with the light-sensing area of the optical sensor chip and the aperture of the bent arm portion, the bent arm portion being disposed between the second lens and the light-sensing area of the optical sensor chip.
