Camera module for a motor vehicle and method of mounting a camera module

1. A camera module for a motor vehicle, comprising:

a lens objective,

a lens holder holding said lens objective, and

a back plate connected to said lens holder and holding an image sensor in or close to an image plane of the lens objective, the back plate being formed by a rigid material,

wherein the alignment of the lens holder relative to the back plate is fixed by a glue joint between the lens holder and the back plate,

wherein a flexible printed circuit board is arranged on the sensor side of the back plate,

wherein the flexible printed circuit board has an opening defining a hole that extends to the back plate, wherein the opening of flexible printed circuit board is larger than the image sensor and the image sensor is at least partially located within the opening, and

wherein the back plate has a first side and a second side, wherein the first side is directly adjacent to portions of each of the lens holder, the image sensor and the printed circuit board.

2. The camera module as claimed in claim 1 , wherein the glue joint is placed in or close to the sensitive plane of the image sensor.

3. The camera module as claimed in claim 1 , wherein the glue joint is placed in or close to the image plane of the lens objective.

4. The camera module as claimed in claim 1 , wherein an attachment between the lens objective and the lens holder is placed in or near the principal plane of the lens objective.

5. The camera module as claimed in claim 1 , wherein the center of the back plate has a non-zero offset relative to the optical z-axis of the lens objective.

6. The camera module as claimed in claim 1 , wherein the back plate is made of metal.

7. The camera module as claimed in claim 1 , wherein the lens objective comprises a lens barrel and/or lens spacers made of metal.

8. The camera module as claimed in claim 7 , wherein the metal is brass.

9. The camera module as claimed in claim 1 , wherein the lens holder is made of metal.
