Camera module with premolded lens housing and method of manufacture
First Claim
1. A digital camera module comprising:
- a pre-fabricated circuit substrate;
a lens housing formed on said pre-fabricated circuit substrate; and
an image capture device coupled to said circuit substrate; and
whereinsaid lens housing allows said image capture device to be mounted to said circuit substrate after said lens housing is formed on said circuit substrate;
said lens housing defines a bore adapted to receive a lens unit; and
a diameter of said bore is sized with respect to a longest diagonal of said image capture device such that said bore facilitates lateral positioning of said image capture device on said circuit substrate.

Abstract
A novel digital camera module includes an image capture device, a circuit substrate, a lens unit and a housing that is mounted to the circuit substrate before the image capture device is mounted to the circuit substrate. In one particular embodiment, the housing is formed onto the circuit substrate via molding. The housing includes a bore to receive the lens unit, with the diameter of the bore being larger than the diagonal of the image capture device such that image capture device can be mounted to the circuit substrate through the bore. In another particular embodiment, the circuit substrate includes an aperture so as to facilitate the flip-chip bonding of the image capture device. The order in which the image capture device and the housing are coupled to the circuit substrate helps prevent damage to the image capture device during the mounting of the housing to the circuit substrate.
