Description

Bearing jig and test equipment Technical Field The invention relates to the technical field of display product testing, in particular to a bearing jig and testing equipment. Background In the flat panel display industry, each display product is fully tested before shipment to ensure the quality of the product. In the processing and preparation process of the display product, a functional test is often added in the process of the Sensor and the FPC, and defective products in the Sensor are firstly screened out, so that the loss of manpower and material resources caused by the fact that the defective products flow to the post-process is reduced, and the cost is reduced. In the prior art, the functional test is often performed by placing the product on an insulating foam platform, and then connecting the product and completing the test by using a test board and product test software matched with the IC scheme manufacturer to judge whether the capacitive touch screen has defects such as open circuit and short circuit and meet the specification requirements of the IC scheme manufacturer. However, the function detection mode of the IC matching production testing tool and software is to calculate the analog capacitance of each node of the screen, and is easily affected by the product attaching state, surface characteristics, environment, warping and the like. In the process of sensor+FPC manufacture procedure, because the surface characteristics of the product are poor, the warping is also great, and the influence of the test environment is added, so that a great amount of misjudgment exists in the function test, and the test passing rate and the yield are seriously influenced. In addition, the state of the sensor+FPC product is inconsistent with the state of the FQC product (lamination LCM), so that the calculated analog capacitance difference is obvious, and the software judging result is inconsistent, so that the phenomena of card passing and card leakage of defective products can occur.
