Image sensor module for camera device
View Patent ↗An image sensor module includes a circuit board ( 20 ), an image sensor ( 10 ) and a supporting board ( 30 ). The circuit board has a plurality of circuits formed thereon. The image sensor is arranged on one side of the circuit board and is electrically connected to the circuit board. The circuit board defines at least one through opening ( 22 ) therein. The supporting board is arranged on an opposite side of the circuit board. A protrusion ( 31 ) extends outwardly from the supporting board through the at least one through opening of the circuit board. The image sensor is mounted on the protrusion.
1. An image sensor module comprising:
a circuit board having a plurality of circuits formed thereon;
an image sensor arranged on one side of the circuit board and being electrically connected to the circuit board, the circuit board defining at least one through opening therein; and
a supporting board arranged on an opposite side of the circuit board, a protrusion extending outwardly from the supporting board through the through openings of the circuit board, a surface of the image sensor which faces to the supporting board being mounted on a top surface of the protrusion, wherein the protrusion comprises three supporting members, a pair of the three supporting members being parallel to each other, the third supporting member being arranged between the pair of supporting members and being non-parallel to the pair of supporting members.
2. The image sensor module of claim 1 , wherein a terminal portion of the protrusion is outside the circuit board, and thus the image sensor is spaced from the circuit board.
3. The image sensor module of claim 1 , wherein the protrusion comprises a square-shaped block, the block has a size being not larger than that of the image sensor, the image sensor being electrically connected to the circuit board.
4. The image sensor module of claim 1 , wherein the protrusion comprises a square-shaped block, the block has a size being larger than that of the image sensor, the image sensor being electrically connected to the circuit board through wire bonding.
5. The image sensor module of claim 1 , wherein the supporting members each has a same height relative to the supporting board.
6. The image sensor module of claim 5 , wherein the circuit board defines a number of long and narrow through openings corresponding to the number of supporting members, the supporting members extending through the corresponding through openings.
7. The image sensor module of claim 5 , wherein all of the supporting members extend through the through openings of the circuit board.
8. The image sensor module of claim 5 , wherein the supporting members are parallel to each other.
9. The image sensor module of claim 1 , wherein an adhesive layer is applied between the image sensor and the protrusion, the adhesive layer being one of thermosetting adhesives, UV adhesives and black adhesives.
10. An image sensor module comprising:
a supporting board forming a supporting surface, a protrusion extending upwardly from the mounting surface;
a circuit board being arranged on the supporting surface of the supporting board, the circuit board defining at least one through opening for extension of the protrusion therethrough, a thickness of the circuit board being smaller than that of the protrusion; and
an image sensor being arranged on the protrusion of the supporting board, a surface of the image sensor which faces to the supporting board being mounted on a top surface of the protrusion, the image sensor being spaced from the circuit board and being electrically connected to the circuit board, wherein the protrusion comprises three supporting members, a pair of the three supporting members being parallel to each other, the third supporting member being arranged between the pair of supporting members and being non-parallel to the pair of supporting members.
11. The image sensor module of claim 10 , wherein the protrusion comprises a square-shaped block, the block has a size being not larger than that of the image sensor, the image sensor being electrically connected to the circuit board.
12. The image sensor module of claim 10 , wherein the protrusion comprises a number of elongated supporting members, with a same height relative to the supporting board, the circuit board defining a number of long and narrow through openings corresponding to the number of supporting members, the supporting members extending through the respective through openings.
