Simple fingerprint module function testing device

Abstract

The invention discloses a simple fingerprint module function testing device comprising a lower pedestal, a rotating shaft, an upper base, a buckle switch, a pressure device, a fake finger pressing head, a fingerprint module placing slot, and a probe connection slot. The lower pedestal is connected with the tail end of an upper hinge by the rotating shaft; the buckle switch is installed at the front end of the lower pedestal; the pressure device is fixed at the upper hinge; the fake finger pressing head is fixed in a fake finger pressing head mounting slot at the bottom of the pressure device;and the module placing slot and the probe connection slot are installed at the lower pedestal. With the fake finger pressing head with the pressure device, electrical performance detection and image quality detection of the fingerprint module can be completed at one single device; because the fake finger pressing head with the pressure device is arranged at the upper base, the overall appearance dimension of the testing device is reduced, so that the operation becomes quick and simple and the production testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of fingerprint module testing, in particular to a simple fingerprint module function testing device. Background technique [0002] At present, electronic products have generally introduced fingerprint recognition functions. The demand for fingerprint recognition modules in consumer electronic products such as mobile phones is increasing day by day, but the supply and shipment cannot keep up with the market demand. Among them, the low efficiency of finished product testing is one of the influencing factors. [0003] Since the functional test of the fingerprint module product needs to use a fake finger indenter to simulate finger imaging on the surface of the fingerprint module to check the image quality, and the chip factory has requirements for the pressure value of the fake finger indenter, so the major fingerprint module manufacturers currently use The fingerprint module product function test fixture is m...

Among them, the low efficiency of finished product testing is one of the influencing factors

[0003] Since the functional test of the fingerprint module product needs to use a fake finger indenter to simulate finger imaging on the surface of the fingerprint module to check the image quality, and the chip factory has requirements for the pressure value of the fake finger indenter, so the major fingerprint module manufacturers currently use The fingerprint module product function test fixture is mainly composed of two parts: the test carrier board and the test frame (the test frame is mainly used to fix the fake finger indenter and adjust a certain pressure), the size of the fixture is too large and the test action is cumbersome. The main reasons for the low test efficiency
