Touch chip simulation press test fixture

Abstract

The invention discloses a touch control chip simulation pressing test fixture. The touch control chip simulation pressing test fixture can be matched with a tester and a plurality of groups of test probes electrically connected with the tester so that electrical performance testing can be performed on chip boards under a pressing condition. The touch control chip simulation pressing test fixture includes a carrying disc module set and a second test module set; the carrying disc module set is used for carrying and positioning a chip board; the second test module set includes a plurality of conductive flexible bodies arranged in a matrix, a flexible body fixing component for fixing the conductive flexible bodies, and a first vertical driving mechanism, wherein each conductive flexible body is corresponding to one touch control chip, and the first vertical driving mechanism is used for driving the flexible body fixing component and the conductive flexible bodies to move up and down so asto make the conductive flexible bodies contact or go away from sensing regions on the corresponding touch control chips; and the second test module set can move transversely relative to the carrying disc module set so as to be positioned in a corresponding rest region of the chip board.

Description

technical field [0001] The invention relates to the field of chip testing, in particular to a touch chip simulation pressing test jig. Background technique [0002] "Fingerprint encryption chip" refers to chip products embedded with fingerprint identification technology, which can realize 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 Internet technology has flourished, driving the rapi...

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.
