Embodiment Construction

[0016] Please also refer to figure 1 and figure 2 , figure 1 It is a schematic cross-sectional view of a camera module according to an embodiment of the present invention. The camera module 1 includes a lens barrel 10 , a lens group 11 , a filter 12 , a ceramic substrate 13 and a photosensitive component 14 . The ceramic substrate 13 is provided with a through hole 131, the through hole 131 is aligned with the lens barrel 10, the photosensitive surface of the photosensitive component 14 is facing the through hole 131, and the optical filter 12 is a blue filter, which passes through the shadowless glue 15 (See figure 2 ) directly pasted on the ceramic substrate 13 to cover the through hole 131 , wherein the shadowless glue 15 is coated on the periphery of the through hole 131 . In order to prevent the filter 12 from shifting or tilting due to the thermal expansion of the air between the filter 12 and the ceramic substrate 13 when using ultraviolet rays to bake, when the s...

Abstract

The invention provides a camera module and a manufacturing method of the camera module. The camera module comprises a lens cone, a lens set, a light filter, a ceramic substrate and a light sensing component, wherein the lens set is fixed in the lens cone; a through hole is formed in the ceramic substrate; the light sensing face of the light sensing component right faces the through hole; the light filter is pasted on the ceramic substrate through shadowless glue and covers the through hole; the specific position on the periphery of the through hole is not coated with shadowless glue, so that an opening is formed between the light filter and the ceramic substrate and serves as a channel for air overflow between the light filter and the ceramic substrate, and the problem that as the light filter is pushed by heated and expanded air when the shadowless glue is roasted through ultraviolet light, the light filter shifts or inclines is avoided.

Description

technical field [0001] The invention relates to a camera module and a manufacturing method thereof. Background technique [0002] At present, portable consumer electronic devices, such as mobile phones, tablet computers, notebooks, etc., are becoming thinner and thinner, and the flip-chip packaging structure camera module is designed to meet future products that are thinner and smaller. In the existing technology, the blue filter is directly bonded on the ceramic substrate by coating a circle of shadowless glue on the ceramic substrate, but when the air between the ceramic substrate and the filter is heated and expanded during baking, there will be The problem of tilting or shifting of the blue filter will affect the quality of the camera module and even cause the product to be scrapped. Contents of the invention [0003] In view of this, the present invention provides a camera module and a manufacturing method thereof to solve the above problems. [0004] A camera modul...
