Method and device for analyzing communication instruction of sorting machine for final test equipment

Abstract

The invention provides an analysis method and device for a communication instruction of a sorting machine of final test equipment. The method is executed by a final test device connected with the sorting machine, and the communication instruction records one of the following items: the occupancy state of at least one station and the grading value of a device corresponding to the at least one station; the method comprises the following steps: extracting the same content of an obtained first communication instruction and an obtained second communication instruction; extracting different contents of the obtained first communication instruction and the second communication instruction; and according to the same content and the different contents, analyzing a coding mode of a character used for indicating the occupancy state of the station or a coding mode of a character used for indicating the gear value of a device corresponding to the station in the communication instruction. According to the method, various types of communication instructions used for the sorting machine of the final test equipment can be analyzed, the sorting machine is used for supporting various types of communication instructions, reusability is good, operation efficiency is high, and the workload and development time for developing a driver corresponding to a new type of instruction are saved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for analyzing communication instructions of a sorter for final testing equipment. Background technique [0002] When automatic test equipment (ATE) performs finished product testing of semiconductor devices (Chip), that is, the final test (FT) process, as the final test equipment, it needs to perform multiple tests with the sorter (Handler). Communication is used to control the manipulator set on the sorting machine to load materials or control the manipulator to sort devices. [0003] For the final test equipment ATE, it needs to communicate with different types of sorting machines. However, different types of sorting machines use different command types to communicate with ATE, and even different types of sorting machines from the same manufacturer use different command types to communicate with ATE. [0004] At present, the common practice ...

AI Technical Summary

Problems solved by technology

[0004] At present, the conventional practice of ATE equipment manufacturers is to develop different drivers (Drivers) according to the different types of communication commands supported by the sorting machine. It is tedious and error-prone, and even makes it impossible to test smoothly

[0005] For ATE equipment manufacturers, in order to support new types of communication commands, it is necessary to develop new drivers, which is time-consuming and labor-intensive, and will also lead to prolongation of the production cycle of ATE equipment and sorting machines

And, one type of sorting machine corresponds to one driving mode, which also brings problems such as tedious and inefficient maintenance and upgrade of ATE equipment
