Abstract

The invention provides a waterproof fingerprint module and an electronic device and relates to the technical field of fingerprint modules. The waterproof fingerprint module includes a fingerprint identification chip, a circuit substrate and a supporting element. The fingerprint identification chip includes a first plane and a second plane. The first plane is electrically connected with the circuitsubstrate. The supporting element comprises a first mounting surface and a second mounting surface opposite to the first mounting surface. The first mounting surface is connected with the second plane of the fingerprint identification chip through a first glue layer. The second mounting surface is connected with the circuit substrate through a second glue layer. By arranging a plurality of planeglue layers on the outer side of the fingerprint identification chip, the stability of the glue layer is enhanced, the glue area is enlarged, the water resistance performance of single glue layer is not affected by air bubbles to prevent water vapor penetration from affecting the electrical connection between the fingerprint identification chip and the substrate, and the waterproof performance ofthe fingerprint module is improved.

Description
