Touch chip electrical test device, equipment and test method

Abstract

The invention discloses a touch control chip electrical performance test device, which comprises a carrier plate module for bearing and positioning a chip board, and first and second test modules arranged at the upper and lower sides of the carrier plate module respectively. The first test module comprises a probe base capable of moving up and down and a plurality of groups of test probes arrangedin the probe base. Each group of probe are used for making contact with a plurality of welding spots on corresponding touch control chips in a correspondence manner. The test module can move horizontally with respect to the carrier plate module to enable the plurality of test probes to be positioned in corresponding test areas of the chip board. The second test module comprises a plurality of conductive soft bodies in matrix arrangement, a soft body fixation member and a first vertical drive mechanism. The first vertical drive mechanism is used for driving the soft body fixation member and the plurality of conductive soft bodies to move up and down to enable the plurality of conductive soft bodies to make contact or separate from sensing areas of the corresponding touch control chips. Thesecond test module can move horizontally with respect to the carrier plate module to enable the second test module to be positioned in a corresponding test area of the chip board.

Description

technical field [0001] The invention relates to the field of chip testing, in particular to a touch chip electrical testing device, equipment and testing method. Background technique [0002] "Fingerprint encryption chip" refers to the chip product with embedded fingerprint identification technology, which can realize the functions of fingerprint image collection, feature extraction and feature comparison on the chip, and can conveniently realize the function of fingerprint encryption. In September 2013, the launch of iPhone 5S, a smart phone with fingerprint recognition function, quickly promoted the promotion and application of fingerprint recognition function in the field of smart phones, and then Samsung, Huawei, VIVO, OPPO, Meizu and other mainstream smart phone manufacturers gradually launched fingerprint recognition functions. Encrypted smartphones. In recent years, under the background of the country's strong support for the concept of Internet plus, domestic Intern...

AI Technical Summary

Problems solved by technology

[0003] 2016 is the first year of the development of fingerprint encryption chips for domestic smartphones. The fingerprint encryption chip adopts a new (Strip) strip packaging process. Mature equipment cannot be directly compatible with the test, which brings huge technical challenges to test scale

The above test method includes 8 manual processes, which undoubtedly increases the probability of abnormal quality and low efficiency. At the same time, the labor cost remains high and cannot meet the needs of production.
