Abstract

The invention relates to a fingerprint recognition module encapsulation structure and fingerprint recognition equipment. The fingerprint recognition module encapsulation structure comprises a chip, a substrate and a base ring, wherein the chip comprises a top surface, a bottom surface and a first matching surface connecting the top surface and the bottom surface; the bottom surface of the chip is connected with the substrate through conductive materials; the face, connected with the chip, of the substrate comprises a second matching surface; the first matching face or / and the second matching surface is provided a plurality of faces; the base ring is provided with a plurality faces matched with first matching surface and the second matching surface; the base ring is matched with the first matching surface of the chip and the second matching surface of the substrate through glue. By the arrangement, the fingerprint recognition module encapsulation structure has the advantages that risk of glue overflowing can be effectively lowered when the base ring is connected with the chip and the substrate through the glue, and appearance cannot be affected by the glue overflowing.

Description

technical field [0001] The invention relates to the field of fingerprint identification module packaging, in particular to a fingerprint identification module packaging structure and fingerprint identification equipment including the fingerprint identification module. Background technique [0002] The fingerprint recognition system is a typical pattern recognition system, including modules such as fingerprint image acquisition, processing, feature extraction and comparison. Fingerprint recognition technology is widely used, such as access control, attendance system, notebook computer, mobile phone, automobile, bank payment can all apply fingerprint recognition technology.
