Description

The image sensor module

Technical field

The utility model belongs to the sensor module, particularly a kind of image sensor module.

Background technology

As shown in Figure 1, existing image sensor module comprises substrate 10, image sensing chip 20, microscope base 24 and lens barrel 32.

Substrate 10 is provided with first surface 12 that forms several first contacts 16 and the second surface 14 that forms several second contacts 18.

Image sensing chip 20 is located on the first surface 12 of substrate 10, and is electrically connected on by several wires 22 on first contact 16 of substrate 10.

Microscope base 24 is the hollow out post, and it is provided with first end 26 and second end 28 that forms internal thread 30.Microscope base 24 is with its second end, 28 glutinous being located on the first surface 12 of substrate 10, so as to shadow being limit sensor chip 20 around living.

Lens barrel 32 be provided with upper surface 34, lower surface 36 and be formed at upper surface 34 and lower surface 36 between external screw thread 38.Lens barrel 32 on the internal thread 30 of microscope base 24, is provided with transparent area 39 with 38 screw locks of external screw thread on it in the lens barrel 32.

Existing image sensor module is because of reserving the lead-in wire bonding of suitable space for lead 22 between image sensing chip 20 and the microscope base 24, so it can't be made into less image sensor module.

Summary of the invention

The purpose of this utility model provides little, the compact image sensor module of a kind of volume.

The utility model comprises substrate, image sensing chip, microscope base and lens barrel; Substrate is provided with upper surface that forms several first contacts and the lower surface that forms several second contacts; Image sensing chip is located at the upper surface of substrate, and is electrically connected on first contact; Microscope base is the hollow out post, and it is provided with first end and second end; First end of microscope base forms internal thread; The inwall of microscope base second end forms breach, makes the internal diameter of second end be slightly larger than the internal diameter of first end; Microscope base makes image sensing chip be positioned at microscope base by the glutinous upper surface of being located at substrate of viscose; Lens barrel is provided with upper surface, lower surface and is formed between the upper and lower end face so as to the external screw thread of screw lock on the internal thread of microscope base; Be provided with transparent area in the lens barrel.

Wherein:

The breach of the inwall of microscope base second end is a triangle.

Image sensing chip is electrically connected on first contact by the several wires that is positioned at the breach below.

Microscope base sticks the upper surface of being located at substrate by viscose, and is pressing the several wires top that is positioned at the breach below.

The excessive glue of viscose is filled in the breach of microscope base second end.

Because the utility model comprises substrate, image sensing chip, microscope base and lens barrel; Substrate is provided with upper surface that forms several first contacts and the lower surface that forms several second contacts; Image sensing chip is located at the upper surface of substrate, and is electrically connected on first contact; Microscope base is the hollow out post, and it is provided with first end and second end; First end of microscope base forms internal thread; The inwall of microscope base second end forms breach, makes the internal diameter of second end be slightly larger than the internal diameter of first end; Microscope base makes image sensing chip be positioned at microscope base by the glutinous upper surface of being located at substrate of viscose; Lens barrel is provided with upper surface, lower surface and is formed between the upper and lower end face so as to the external screw thread of screw lock on the internal thread of microscope base; Be provided with transparent area in the lens barrel.On being formed at microscope base during breach, the part that is electrically connected image sensing chip and substrate first contact can be hidden and be located in the breach, therefore, when the image sensing chip of same size is made module, can reduce the size of microscope base effectively, make image sensor module volume little, compact, thereby reach the purpose of this utility model.

Embodiment

As shown in Figure 2, the utility model comprises substrate 50, image sensing chip 52, microscope base 54 and lens barrel 56.

Substrate 50 is provided with upper surface 58 that forms several first contacts 62 and the lower surface 60 that forms several second contacts 64.

Image sensing chip 52 is located at the upper surface 58 of substrate 50, and is electrically connected on first contact 62 by several wires 66.

Microscope base 54 is the hollow out post, and it is provided with first end 68 and second end 70 that forms internal thread 72.The inwall of second end 68 forms the breach 74 of triangle, makes the internal diameter of second end 70 be slightly larger than the internal diameter of first end 68.Microscope base 54 is by the viscose 76 glutinous upper surfaces 58 of being located at substrate 50, make image sensing chip 52 be positioned at microscope base 54, and pressing the top of the several wires 66 that is positioned at breach 74 belows, and the excessive glue 78 of viscose 76 will be filled in the breach 74, and lead 66 will partly be enveloped.

Lens barrel 56 be provided with upper surface 80, lower surface 82 and be formed at upper surface 80 and lower surface 82 between external screw thread 84.Lens barrel 56 with 84 screw locks of external screw thread on it on the internal thread 72 of microscope base 54.Be provided with transparent area 86 in the lens barrel 56.

In this way, the utlity model has following advantage:

When 1, microscope base 54 formed breach 74, lead 66 can be hidden and be located in the breach 74, therefore, when the image sensing chip 52 of same size is made module, can reduce the size of microscope base 54 effectively, made module reach compact demand.

2, the excessive glue 78 of viscose 76 can be filled in the breach 74, prevents that effectively aqueous vapor from entering in the module, so as to the reliability of effective raising product.
