Abstract

The invention relates to the technical field of PCB testing, particularly relates to a multi-channel low-resistance test system and is suitable for a PCB access resistance value detection process. Thesystem comprises a data acquisition unit for PCB access resistance data acquisition, a test unit for data acquisition unit detection, an upper computer connected with the test unit and a current source used for providing electric power support, wherein the upper computer is suitable for sending a test instruction for detection of the data acquisition unit to the test unit, the test unit sends a corresponding test signal to the data acquisition unit according to the test instruction, and the upper computer is further suitable for receiving detection data fed back by the data acquisition unit and obtained by the test unit, and is used for monitoring a PCB online. The system is advantaged in that by adopting an automatic control principle, problems of possible interference, instability and the like in the manual measurement process are solved, and long-term on-line monitoring can be performed on the PCB which is placed in the environment test box and is subjected to a high-low temperature impact test, so the resistance change condition of a PCB passage in different environments can be conveniently observed.

Description

technical field [0001] The invention relates to the technical field of PCB testing, in particular to a multi-channel low-resistance testing system. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. [0003] In the PCB multi-channel low-resistance test, low resistance and high test accuracy are required. In the existing technology, manual testing is mostly used. However, technical problems such as interference and instability may occur during the manual measurement process, and there is also a lack of online monitoring of the test status. Contents of the invention [0004] The present invention aims to solve the above-mentioned problems. [0005] To achieve th...
