Digital image capturing module assembly and method of fabricating the same
First Claim
1. A digital image capturing module assembly, which comprises:
- a lens holder, which has one side defined as a focusing plane, and which is formed with a plurality of aligning posts on the periphery of the focusing plane;
a washer, which is mounted on the periphery of the focusing plane of the lens holder; and
a photosensitive printed circuit board, which is formed with a plurality of aligning holes corresponding to the aligning posts on the lens holder, and which is mounted on the washer on the lens holder by fitting the aligning holes thereof to the aligning posts on the lens holder;
wherein the respective tips of the aligning posts on the lens holder are each melted into a bolting structure to secure the photosensitive printed circuit board firmly in position on the lens holder;
and wherein the firmly-secured photosensitive printed circuit board forcefully presses against the washer to thereby allow the washer to provide a sealed light-impenetrable effect at the junction between the photosensitive printed circuit board and the lens holder.

Abstract
A digital image capturing module assembly and method of fabricating the same is proposed, which is used for the assembly of a digital image capturing module from a photosensitive printed circuit board and a lens holder. The proposed module assembly is characterized by the use of aligning posts on the lens holder to help align and secure the photosensitive printed circuit board in position on the lens holder as well as by the use of a washer to help provide a sealed light-impenetrable effect at the junction between the photosensitive printed circuit board and the lens holder so that no sidelight can pass therethrough to the inside of the lens holder. This feature allows the assembly process to be more simplified and less time-consuming to implement than prior art, which can help increase the yield of the assembly of digital image capturing module.

6. A method for fabricating a digital image capturing module, comprising:
-
preparing a lens holder which has one side defined as a focusing plane, and which is formed with a plurality of aligning posts on the periphery of the focusing plane;
preparing a photosensitive printed circuit board which is formed with a plurality of aligning holes corresponding to the aligning posts on the lens holder;
mounting a washer on the periphery of the focusing plane of the lens holder;
mounting the photosensitive printed circuit board in position on the washer on the lens holder by fitting the aligning holes in the photosensitive printed circuit board to the aligning posts on the lens holder;
melting the respective tips of the aligning posts on the lens holder so as to transform the respective tips of the aligning posts into a bolting structure to secure the photosensitive printed circuit board in position on the lens holder as well as to allow the photosensitive printed circuit board to forcefully presses against the washer to thereby allow the washer to provide a sealed light-impenetrable effect at the junction between the photosensitive printed circuit board and the lens holder. - View Dependent Claims (7, 8, 9, 10)
