Embodiment Construction

[0032] Please refer to attached figure 1 As shown, the hardware involved includes four station turntables driven by motors, electric control system, air control system, cylinder, Fixture (action control board), PC, test board, touchable LCD display, Computer display screen and customer service system, etc.

[0033] Among them, the test boards of each test part are set on the cylinders, driven by the cylinders, and the air control system controls the lifting of the cylinders, so that the test boards are in contact with the chips to be tested, so as to achieve the purpose of testing.

[0034] The test chips are placed in the stations of the four-station turntable, and the turntable is controlled by the electric control system to rotate, so that the test chips are tested sequentially through different test boards.

[0035] figure 2 As shown, it is the turntable automatic test device realized by the present invention, which includes a motor, a turntable and a barcode scannin...

Abstract

The invention discloses a turntable automatic testing device and method. The device comprises a motor, a turntable, and a bar code scanning gun. The motor drives the turntable to rotate. The turntable is equipped with at least four operating positions including an ICT testing position, a tone leakage testing position, a sensitivity testing position, and a discharging position which are used for testing an ICT, testing tone leakage, testing sensitivity, and discharging materials respectively. The bar code scanning gun is arranged on the center of the turntable in order to scan a bar code on the corresponding operating position. The device and the method may achieve full-automatic testing. From loading to testing, a tester is just required to place a test sample in a SOCKET and following testing is basically intellectualized and automated. In addition, the device and the method may achieve parallel testing and prevent parallel testing incapability caused by the characteristic of the test sample.

Description

technical field [0001] The invention belongs to the technical field of automatic testing, in particular to an automatic system solution for ICT (incircuit tester) testing and MIC (sensitivity and leakage) testing. Background technique [0002] At present, the ICT test and MIC test of most manufacturers need manual switching test, and because the MIC test takes a long time, especially in the ICT test, there are the following deficiencies in the following aspects. First, manual scanning is required. There are two barcodes, one is the barcode of the product itself, and the other is the barcode of the MIC test module. It takes about 5S to manually scan these two barcodes. Second, after placing the DUT (device under test), due to the large number of test items, the test is divided into several parts, and each part cannot be run in parallel. The tester needs to wait for the completion of the previous test item before entering the next test. The project needs to wait for (5-10)S, ...
