Chip module structure for particles protection
View Patent ↗The present invention provides a chip module structure for particles protection. The structure includes a substrate. A chip is configured on the substrate, with a sensing area. A holder is disposed on the substrate, wherein the holder has a first rib. A transparent material is disposed on the holder, substantially aligning to the sensing area. A lens holder is disposed on the holder, and a lens is configured on the lens holder, substantially aligning to the transparent material and the sensing area. The lens has a second rib, wherein the second rib is disposed corresponding to the first rib for blocking particles entering into the chip module structure.
1. A chip module structure for particles protection, comprising:
a substrate;
a chip configured on said substrate, with a sensing area;
a supporting holder disposed on said substrate, wherein said supporting holder has a first protrusion structure; and
a lens holder disposed on said supporting holder, and a lens configured on said lens holder, substantially aligning to said sensing area;
wherein said lens has a second protrusion structure, wherein said second protrusion structure of said lens is disposed opposite to said first protrusion structure of said supporting holder, and wherein said first protrusion structure and said second protrusion structure extend in opposite direction,
wherein said second protrusion structure of said lens does not contact with said supporting holder for blocking particles by a first side of said first protrusion structure of said lens, and
wherein said first protrusion structure of said supporting holder does not contact with said lens and said second protrusion structure is separated by a spacing from said first protrusion structure in the horizontal direction for blocking particles by a second side of said first protrusion structure of said supporting holder entering into said chip module structure.
2. The module structure of claim 1 , wherein said supporting holder has a groove structure formed therein for allowing said chip disposed therein, and a through hole structure for exposing said sensing area of said chip.
3. The module structure of claim 1 , wherein said supporting holder has a ring groove structure located at a side of said through hole structure for a transparent plate disposed thereon.
4. The module structure of claim 1 , wherein said chip is adhered to said substrate via a first adhesion layer, said supporting holder adhered to said substrate via a second adhesion layer, and said lens holder adhered to said supporting holder via a third adhesion layer.
5. The module structure of claim 1 , wherein said first protrusion structure is located on a top surface of said supporting holder, and said second protrusion structure is located on a bottom surface of a side of said lens.
6. The module structure of claim 1 , wherein said lens holder is a plastic piece or an actuator.
7. The module structure of claim 6 , wherein said actuator includes a voice coil motor or a micro electro mechanical system.
8. The module structure of claim 1 , wherein height of a bottom surface of said second protrusion structure is less than or equal to that of a top surface of said first protrusion structure.
9. The module structure of claim 1 , wherein said substrate is a printed circuit board or a flexible printed circuit board.
10. The module structure of claim 9 , further comprising a transparent material disposed on said supporting holder, substantially aligning to said sensing area.
11. The module structure of claim 10 , wherein said supporting holder has a groove structure formed therein for allowing said chip disposed therein, and a through hole structure for exposing said sensing area of said chip.
12. The module structure of claim 10 , wherein said supporting holder has a ring groove structure located at a side of said through hole structure for a transparent plate disposed thereon.
13. The module structure of claim 10 , wherein said chip is adhered to said substrate via a first adhesion layer, said supporting holder adhered to said substrate via a second adhesion layer, and said lens holder adhered to said supporting holder via a third adhesion layer.
14. The module structure of claim 10 , wherein said first protrusion structure is located on a top surface of said supporting holder, and said second protrusion structure is located on a bottom surface of a side of said lens.
15. The module structure of claim 10 , wherein said lens holder is a plastic piece or an actuator.
16. The module structure of claim 15 , wherein said actuator includes a voice coil motor or a micro electro mechanical system.
17. The module structure of claim 10 , wherein height of a bottom surface of said second protrusion structure is less than or equal to that of a top surface of said first protrusion structure.
18. The module structure of claim 10 , wherein said substrate is a printed circuit board or a flexible printed circuit board.
