Abstract

The invention discloses a chip testing method, which is used in a chip testing system. The chip testing system includes a testing machine and a classification machine. The testing machine includes a plurality of testing units. The chip testing method includes: configuring the testing machine to execute: testing the chip through each testing unit ;Generate bin signals according to the test results of each test unit and the pre-configured mapping relationship; transmit the bin signals to the sorter; configure the sorter to execute: receive the bin signals; according to the correspondence between the pre-configured bin signals and each outlet The chip is placed on the tray of the corresponding outlet; the position information of the chip on the tray is recorded, and a map is generated based on the position information of each chip and its corresponding bin signal, which realizes the detailed test results of the chip , the staff can directly see the test results of the chip in each test unit and the distribution details of defective products through the map, so as to make corresponding improvement plans. In addition, the invention also discloses a chip testing system.

Description

technical field [0001] The invention relates to the technical field of chip testing, in particular to a chip testing method and a chip testing system. Background technique [0002] Chip, also known as microcircuit (microcircuit), microchip (microchip), integrated circuit (integrated circuit), refers to a silicon chip containing an integrated circuit, which is small in size and is an important part of electronic equipment such as computers. Due to the fine structure of the chip, the complex manufacturing process and the cumbersome process, it will inevitably leave potential defects in the production process, so that the manufactured chip cannot meet the standard requirements, and may fail due to various reasons at any time. Therefore, in order to ensure the quality of the chip, the chip is usually tested (including multiple test items such as electrical parameter measurement and functional test) in order to separate good and bad products. [0003] At this stage, the chip is ...
