The invention discloses a fingerprint module and a mobile terminal. The fingerprint module includes a circuit board, a fingerprint chip and components. The fingerprint chip is provided with a fingerprint sensor. There is a flange, an installation space is formed between the flange and the circuit board, the components are installed on the circuit board, and the components are located in the installation space. Since the position where the fingerprint chip is located has a relatively high structural strength, there is no need to set up additional reinforcing plates for the installation of components, which makes the structure of the fingerprint module simpler and its cost lower. At the same time, the distance between the components and the fingerprint chip is closer, which improves the performance of the fingerprint chip; the components and the fingerprint chip are arranged on the same side of the circuit board, so the components and the fingerprint chip can be mounted on one side Assembling, the cost of this assembly method is lower, so the cost of the fingerprint module is reduced accordingly.
Description
technical field [0001] The invention relates to the technical field of communication equipment, in particular to a fingerprint module and a mobile terminal. Background technique [0002] The fingerprint module is one of the core components of the mobile terminal. With the continuous development of the mobile terminal industry, people have higher and higher requirements for the performance of the fingerprint module, which brings a relatively large challenge to the structural design of the fingerprint module. [0003] Traditional fingerprint modules usually include circuit boards, fingerprint chips, components and reinforcement boards. Among them, the fingerprint chip and the components are arranged on the circuit board, and the two are usually arranged on the two sides of the circuit board facing away from each other; strength afterwards. [0004] In the above-mentioned fingerprint module, the mounting strength of the components needs to be ensured by a reinforcing plate, a...
