Image sensing module and capsulation method thereof

Abstract

The invention relates to an image sensing module, which comprises an image sensing unit, a lens group and glue, wherein the image sensing unit comprises a substrate, an image sensing chip positioned on the upper surface of the substrate, a plurality of metal leads which are electrically connected and span between the substrate and the image sensing chip and a transparent cover plate arranged on image sensing chip; the lens group is arranged on the image sensing unit and comprises a lens cone and a plurality of lenses embedded in the lens cone fixedly; and the glue is dripped at the joint of the lens group and the image sensing unit to fix the lens group on the image sensing unit.

Description

technical field [0001] The invention relates to an image sensing module, in particular to a thinned image sensing module. Background technique [0002] With the advancement of technology, various handheld mobile devices are integrated with digital camera functions, such as mobile phones, personal digital assistants (PDAs), and digital cameras, to satisfy people's desire to record every bit of life anytime and anywhere. [0003] The main core component of these digital camera functions is an image sensing module, and the image sensing module at least includes an image sensing unit and a lens group. An image sensing unit is a semiconductor component that converts an optical image into an electronic signal. The lens group is mainly used to image the external scene on the image sensing unit. [0004] In order for the lens group to accurately image the external image on the image sensing unit, the lens group needs to be placed in the center of the image sensing unit, and the be...

Problems solved by technology

[0006] In addition to the complicated steps of the above-mentioned packaging process, the distance between the screw thread and the lens group is also an important consideration in the process. If the distance is too short, the lens group and the image sensing unit cannot be effectively completed accurately. Positioning; if the distance is too large, it may cause the lens group to tilt, resulting in errors during use

When the lens group is adjusted and positioned, the fine dust caused by the screw teeth will also affect the imaging quality of the image sensing unit, resulting in a loss of pass rate

In addition, after the positioning is completed, the lens group needs to be transferred to the back end to complete the dispensing. During the transfer process, the original positioning position may be shifted, which will affect the overall pass rate of the product.
