Integrated circuit sorting fool-proof system and method

Abstract

The invention relates to an integrated circuit sorting fool-proof system and method. The system comprises a PC computer, a sorting machine and a display device provided with a plurality of display areas. The sorting machine comprises a plurality of optional charge pipes with different colors, and the PC computer outputs gear information according to the test result of to-be-sorted chips; and split charging is conducted on the to-be-sorted chips into the optional charge pipes with the different colors by the sorting machine according to the gear information. The display device is connected with the PC computer, the display areas and the optional charge pipes are arranged in a one-to-one correspondence mode, and the display device displays the color information of the corresponding optional charge pipes and the gear information of the chips placed in the optional charge pipes on the multiple display areas according to the gear information output by the PC computer. In the actual operational process, an operator can place the optional charge pipes with the corresponding colors according to the gear information and digital information which are displayed by the display areas in the display device, the operator can be prevented from placing the optional charge pipes on wrong positions, the misplacement rate is reduced, and further the working efficiency can be improved. In addition, the invention provides the integrated circuit sorting fool-proof method.

Description

technical field [0001] The invention relates to the technical field of integrated circuit testing, in particular to an integrated circuit sorting foolproof system and method. Background technique [0002] In the integrated circuit final test (Final Test) process, an automatic test machine (Auto Test Equipment, ATE) in the integrated circuit test equipment applies a test signal to the chip to be tested, and performs a performance test on the chip to be tested. The automatic testing machine sorts the test results into multiple gears according to the current transfer ratio (CTR) of the chip, and sends the sorting control information to the sorting machine (Handler). The sorting machine sorts the tested chips according to the sorting control information, sorts and transports the chips of different gears to the corresponding tubes of different colors, and then can identify the attributes of the chips according to the tubes of different colors. [0003] Generally, during the actu...
