Problems solved by technology

However, traditional circuit board testing instruments are often aimed at single or fixed test equipment for several circuit boards, and there are many obvious deficiencies
First of all, its degree of automation is low: there are many switches on the panel of traditional test instruments, and many switches need to be operated during the test process. The operation process is complicated, the work quality and efficiency are difficult to improve, and the test work is easily affected by human factors, making the test process difficult. Precise contr...

Abstract

The invention discloses a universal circuit board test system, which comprises a test machine table and test software, wherein the test machine table comprises automatic test resources and a matrix switch, the automatic test resources are integrated together through a bus and are connected with the matrix switch and a PC (personnel computer) through interfaces, the PC is configured with the test software, the test software outputs a power supply or a signal meeting the requirements through controlling the automatic test resources via the bus, an output signal of a tested circuit board is read, meanwhile, the matrix switch is controlled through the bus so that the corresponding lead pin type in a socket is matched with the lead pin of the tested circuit board, in the work process, the interface definition of the circuit board is added into a test software database, the system automatically switches each lead pin function of the socket for outputting the signal or the power supply conforming to the requirements, in addition, the output interface of the circuit board is automatically connected onto corresponding equipment of the automatic test resources, and the parameters and the waveform of each output interface of the circuit board are displayed through the software interface. The universal circuit board test system has the advantages that the expandability is high, the universality is high, the automation degree is high, the operation is convenient, and the like.

Description

technical field [0001] The invention relates to the technical field of circuit board testing systems, in particular to a general circuit board testing system. Background technique [0002] The circuit board is an indispensable part in the development and production of electronic systems. Its quality directly affects the quality of the complete machine equipment. Its production and inspection cycle affects the development progress and delivery time of the complete machine. Therefore, the test of the circuit board is related to An important link in the quality and production cycle of electronic systems. However, traditional circuit board testing instruments are often aimed at testing equipment for a single or several fixed circuit boards, and there are many obvious deficiencies. First of all, its degree of automation is low: there are many switches on the panel of traditional test instruments, and many switches need to be operated during the test process. The operation proces...
