Smart phone fingerprint module set whole-version test system

Abstract

The invention discloses a smart phone fingerprint module set whole-version test system. The system comprises a base, a core board, a substrate, a PCB, a supporting plate, a carrying plate, a manual downward pressing mechanism and a data display mechanism; the PCB is mounted on the upper surface of the substrate; the supporting plate is mounted on the upper surface of the PCB; the carrying plate is located directly above the supporting plate; the core board is connected with the PCB through a DuPont line; a pin holder with pins is inserted into a mounting through hole of the supporting plate; a line concentration box is arranged below the substrate; the core board is distributed in the line concentration box; the data display mechanism includes a supporting seat, a hanging plate and a display, wherein the supporting base and the hanging plate are mounted on the base, and the display is mounted on the hanging plate; and the host machine of the display is connected with the core board through a data line. According to the smart phone fingerprint module set whole-version test system of the invention, by means of the whole-version test board, the requirements of the test of a plurality of groups of chips can be satisfied, whole-version chip products which have been processed can be detected with one step, and therefore, the system is convenient and quick and can reduce repetitive labor and greatly improve working efficiency.

Description

technical field [0001] The invention relates to a smart phone fingerprint module full-page testing system, and relates to the field of mobile phone fingerprint chip processing. Background technique [0002] As people's requirements for information security are getting higher and higher, traditional digital passwords or Jiugongge passwords can no longer meet people's requirements for information security. Biometric identification is widely used in new-generation electronic devices, and the stability and uniqueness of fingerprints make fingerprint identification devices widely used. [0003] Fingerprint chips usually need to be tested in factory quality inspection, recycled product inspection, and performance testing. Usually, the detection fixture includes a fixture base plate with a detection circuit, a detection base fixed on the fixture base plate, and a fixture base plate on the fixture base plate.

[0003] Fingerprint chips usually need to be tested in factory quality inspection, recycled product inspection, and performance testing. Usually, the detection fixture includes a fixture base plate with a detection circuit, a detection base fixed on the fixture base plate, and a fixture base plate on the fixture base plate. Set the detection probe connected to the detection circuit and matched with the electronic chip; when testing, place the chip on the detection base, and the detection probe should touch the detection point of the corresponding chip. Generally, the upper end of the chip is simply pressed by a pressing block The chip or sometimes the chip is welded on the detection base, so that the chip is close to the detection probe for detection. However, the chip is easily misplaced on the detection base, and the insufficient force on the upper end of the chip will easily cause some parts to not be in contact with the detection probe. It leads to inaccurate detection results. In addition, the existing detection mostly uses a single jig to detect a single chip, with many repeated operations and low work efficiency.
