Problems solved by technology

In the past, most of the circuit board testing tools needed to build a complex system to simulate the actual working environment of the circuit board to test the circuit board, and also involved the cooperation of multiple circuit boards. The development cycle of the circuit board testing tool was relatively long, and High cost and low test efficiency
[0003] At present, the more commonly used circuit board testing tools are ICT testing tools (that is, automatic online testers). By directly testing the electrical properties of online devices, defects in the manufacturing process and defective components are found.

Abstract

The invention provides a circuit board testing device which comprises a tooling body, wherein the tooling body is provided with a testing circuit module, a power supply interface, a power supply converter and a thimble module, the power supply interface is connected with the testing circuit module through the power supply converter, and the testing circuit module is connected to an external circuit board to be tested of the circuit board testing device through the thimble module. A CPU (central processing unit) of the testing circuit module is used for generating a test signal according to a default program; the test signal is transmitted to the circuit board to be tested, passes through a current passage of the circuit board to be tested and then returns to the testing circuit module; and the CPU is used for contrasting the test signal outputted by the CPU with the input test signal, judging the test result of the current passage and switching to the next passage of the circuit board to be tested if the testing is not totally completed. The circuit board testing device provided by the invention can simplify the testing process steps and improve the testing efficiency, and simultaneously has the advantages of programmability, flexible application, simple structure and low production cost.

Description

【Technical field】 [0001] The invention relates to a testing device for a circuit board and a testing method for the testing device. 【Background technique】 [0002] When the circuit board design is completed and enters the mass production stage, in order to ensure the reliable quality of each circuit board produced, each circuit board must be tested, for which it is necessary to develop a corresponding circuit board test tooling. In the past, most of the circuit board testing tools needed to build a complex system to simulate the actual working environment of the circuit board to test the circuit board, and also involved the cooperation of multiple circuit boards. The development cycle of the circuit board testing tool was relatively long, and The cost is high and the test efficiency is low. [0003] At present, the more commonly used circuit board testing tools are ICT testing tools (that is, automatic online testers). By directly testing the electrical properties of online...
