Title: FINGERPRINT RECOGNITION DEVICE
Abstract:
A fingerprint recognition device, comprising: a circuit board (1), a conductive component (2), a sensor chip (3), a collar (4) and a cover plate (6); the sensor chip (3) being provided on the circuit board (1) by means of the conductive component (2), the collar (4) surrounding the outer side of the sensor chip (3), the cover plate (6) covering the sensor chip (3) and the collar (4) from above. By adding, on the outer side of the sensor chip (3) having a minimum package, a collar (4) of which the color and material are close to those of the sensor chip (3), said fingerprint recognition device solves the problem that the dimensions of the sensor chip (3) having a minimum package cannot meet appearance requirements, avoids the problem of deformation of the cover plate (6), caused due to the fact that the cover plate (6) is prone to stress pulling after the cover plate (6) has been bonded in the case of use of a support frame, and the problem of color difference after the cover plate (6) has been bonded, and reduces module costs.
