Method for integrating a dispensable light transmissible aperture in the cap of a thin light sensor module

A light sensor module comprising:

• a substrate:
• a light sensing circuit connected to a first interconnect on the substrate;
• a light sourcing circuit connected to a second interconnect on the substrate;
• and
• a cap affixed to the substrate to cover the light sensing circuit and light sourcing circuit, the cap comprising:
• a top wall;
• a sidewall extending perpendicularly from the top wall and extending therearound;
• a partition sidewall extending from one portion of the sidewall to another portion of the sidewall to thereby define first and second cavities, the first cavity being positioned over the light sensing circuit, the second cavity being positioned over the light sourcing circuit;
• wherein the first cavity includes a first central through-opening that extends through the top wall;
• a first lens installed within the first central through-opening, with the first lens having a cavity defined in its exterior sidewall to completely encircle a lower portion of the exterior sidewall;
• the first central through-opening being defined by a first interior sidewall extending through the top wall, with a first ridge extending outwardly from the first interior sidewall, the first interior sidewall and first ridge being integrally formed as a monolithic unit;
• at least one first relief blind-opening that extends into but not through the top wall, wherein the at least one first relief blind-opening intersects the first central through-opening so as to be in fluid communication therewith;
• wherein the first ridge extends completely around the first interior sidewall so that the first lens is mechanically anchored in place by the first ridge interfacing with an entirety of the cavity defined in the exterior sidewall of the first lens, while an upper portion of the exterior sidewall of the first lens extends into the at least one first relief blind-opening and in physical contact with portions of the top wall defining the at least one first relief blind-opening;
• wherein the second cavity includes a second central through-opening that extends through the top wall;
• a second lens installed within the second central through-opening, with the second lens having a cavity defined in its exterior sidewall to completely encircle a lower portion of that exterior sidewall;
• the second central through-opening being defined by a second interior sidewall extending through the top wall, with a second ridge extending outwardly from the second interior sidewall, the second interior sidewall and second ridge being integrally formed as a monolithic unit;
• at least one second relief blind-opening that extends into but not through the top wall, wherein the at least one second relief blind-opening intersects the second central through-opening so as to be in fluid communication therewith;
• and
• wherein the second ridge extends completely around the second interior sidewall so that the second lens is mechanically anchored in place by the second ridge interfacing with the entirety of the cavity defined in the exterior sidewall of the second lens, while an upper portion of the exterior sidewall of the second lens extends into the at least one second relief blind-opening and in physical contact with portions of the top wall defining the at least one second relief blind-opening.
