Problems solved by technology

[0003] At present, the installation process of the fingerprint identification module is to weld the fingerprint identification chip on the circuit board through SMT (Surface Mount Technology, surface mount technology). The adhesive space is getting smaller and smaller, resulting in the overflow of adhesive glue on the edge of the fingerprint identification chip during the assembly process of the fingerprint identification module

Abstract

The invention discloses a flexible circuit board. The flexible circuit board comprises a first cover film layer which comprises a first top surface and a second surface arranged oppositely to the first top surface; and a first conductive layer which is arranged on the second surface of the first cover film layer, wherein the first top surface comprises a chip mounting area; a through groove around the chip mounting area is formed in the first top surface; and the through hole runs through the first top surface and the second surface. The through hole is used for containing adhesive glue which flow outwards when the fingerprint identification chip is fixed with the flexible circuit board, so that the condition that the adhesive glue overflows at the outer sidewall of the flexible circuit board in an assembling process of the fingerprint identification module can be prevented efficiently, and excessive glue also can be prevented efficiently. Meanwhile, the fingerprint identification module applying the flexible circuit board is also provided.

Description

technical field [0001] The invention relates to the field of biological identification, in particular to a fingerprint identification module and a flexible circuit board thereof. Background technique [0002] In recent years, with the continuous development of science and technology, the fingerprint identification module not only needs to meet higher identification performance, but also tends to develop in the direction of miniaturization. [0003] At present, the installation process of the fingerprint identification module is to weld the fingerprint identification chip on the circuit board through SMT (Surface Mount Technology, surface mount technology). The glue space is getting smaller and smaller, resulting in the overflow of the adhesive glue on the edge of the fingerprint recognition chip during the assembly process of the fingerprint recognition module. Contents of the invention [0004] Based on this, it is necessary to provide a fingerprint identification module...
