Classification: CPC H | IPC H

Claim 24:
25. A digital image sensor package, comprising:
an image sensor substrate carrying photodiodes;
a printed circuit board carrying the image sensor substrate;
a glass covering having a bottom surface, a top surface opposite the bottom surface, and a sidewall delimiting a perimeter edge of the glass covering, wherein the glass covering overlies the photodiodes;
wherein a surface area of the top surface of the glass covering is greater than a surface area of the bottom surface of the glass covering such that the sidewall is anti-perpendicular to one or both of the top and bottom surfaces of the glass; and
mounting hardware physically coupling portions of the bottom surface of the glass covering to the printed circuit board, wherein the mounting hardware comprises:
a first portion physically coupled to the printed circuit board and extending upwardly therefrom;
a second portion extending inwardly from a periphery of the image sensor substrate toward the photodiodes so as to define an aperture over the image sensor substrate; and
an intermediate connecting portion connecting the first portion to the second portion;
wherein portions of the bottom surface of the glass covering are physically coupled to a top face of the second portion of the mounting hardware so that the glass covering extends over and across the aperture, the top face of the second portion being opposite to a bottom face of the second portion, the bottom face of the second portion directly facing the image sensor substrate.
