Abstract

The invention discloses an image module and a manufacturing method thereof. The image module comprises a lens assembly, an image sensing component, an anisotropic conductive adhesive and a circuit board. The circuit board possesses a first plate surface and a second plate surface. The image sensing component is arranged on the second plate surface. The lens assembly is arranged on the first plate surface. The anisotropic conductive adhesive is arranged between the second plate surface of the circuit board and the image sensing component so that the image sensing component is electrically connected to the circuit board. The manufacturing method of the image module comprises the following steps that the anisotropic conductive adhesive is coated on the second plate surface; thermal compression bonding processing is performed on the image sensing component and the anisotropic conductive adhesive so that the image sensing component is fixedly connected and electrically connected with the second plate surface; the lens assembly is arranged on the first plate surface and the image sensing component is packaged.

Description

technical field [0001] The invention relates to a module and its manufacturing method, in particular to an image module and its manufacturing method. Background technique [0002] The development of modern electronic products is becoming more and more thin and miniaturized. At present, most of the image-related products are still produced in the traditional SMT (Surface-mount Technology) method, but the SMT process is limited by the sensing element ( Sensor Die) needs to be packaged with COB (Chip on Board) first before SMT can be carried out, so that the total height and cost of the image module cannot be reduced, which is not conducive to the demand for thinning, and the higher-level COB / FLIP CHIP process, although The height of the image module can be reduced, but its construction and maintenance costs are too high, and if it does not reach a certain scale of production, there will be no economic benefits. [0003] For this reason, see Figure 5 , there was an industry d...
