Automatic identification adapter for ATE automatic test system and identification method of automatic identification adapter

Abstract

The invention relates to an automatic identification adapter for an ATE automatic test system and an identification method of the automatic identification adapter. The automatic identification adaptercomprises a processing module, and a cable resistance identification module, a state indication module and a power supply control module which are respectively connected with the processing module, wherein the processing module is used for receiving the ID number of the adapter and then comparing the ID number with the solidified ID number of the adapter so as to judge whether the model of the adapter is matched or not and give a judgment result. According to the adapter for safe connection and reliable test of the ATE test system and the tested product, on one hand, faults of the tested product caused by wrong connection of the adapter and a cable are avoided, and the effect of safety protection of the tested product is achieved; measurement and identification are carried out through theprocessing module, testing of ATE hardware resources is replaced, and occupation of equipment resources is reduced. In addition, the processing module can meet the recognition requirements of variousATE test systems by changing the ID number and the cable resistance value in the solidification program of the recognition module, and has certain universality.

Description

technical field [0001] The invention relates to the technical field of ATE automatic testing, in particular to an automatic identification adapter for an ATE automatic testing system and an identification method thereof. Background technique [0002] With the technical development of ATE automatic test system, the requirements for generalization of equipment are getting higher and higher. A general automatic test system can meet the detection requirements of various products, which requires an interface adapter module that meets the product test requirements. In order to reduce The wrong installation of the adapter and test cable caused by human error causes the power-on damage of the tested part. It is necessary to automatically identify each interface adapter and supporting cable before the tested product is powered on to ensure that the ATE test system and the tested product are connected correctly. Now The existing technology is mainly to identify the resistance in the c...

[0002] With the technical development of ATE automatic test system, the requirements for generalization of equipment are getting higher and higher. A general automatic test system can meet the detection requirements of various products, which requires an interface adapter module that meets the product test requirements. In order to reduce The wrong installation of the adapter and test cable caused by human error causes the power-on damage of the tested part. It is necessary to automatically identify each interface adapter and supporting cable before the tested product is powered on to ensure that the ATE test system and the tested product are connected correctly. Now The existing technology is mainly to identify the resistance in the cable and judge the correctness of the cable connection. This type of method lacks the identification of different adapters
