Abstract:
A sensor package assembly for use with an optical assembly, said sensor package assembly comprising:a lead frame; an image sensor mounted on the lead frame and defining an image plane, said image sensor including leads extending from the lead frame; an optics base mechanism for supporting the optical assembly in relation to an optical axis, said optical assembly comprising multiple optics-related parts, said optics base mechanism having at least three optics-related locator features positioned to define a first plane substantially parallel to the image plane; a sensor mounting frame for locating and supporting the image sensor in relation to the optical axis, said sensor mounting frame having an opening for allowing the leads to extend through and at least three frame-related locator features protruding therefrom and positioned to define a second plane substantially parallel to the image plane; and means for fastening the optics base mechanism and the sensor mounting frame together with the image sensor interposed therebetween such that each of the optics-related locator features is oriented in opposed relation to a corresponding one of the frame-related locator features with the lead frame pinched between opposing surfaces of the optics-related locator features and the frame-related locator features, so that the optical axis is substantially perpendicular to the first, second, and image planes to reduce tilt of the image sensor relative to the optical axis.
