A general circuit board testing system

Abstract

The invention discloses a general circuit board testing system, which includes a test machine and test software. The test machine includes automatic test resources and a matrix switch; the automatic test resources are integrated through a bus and connected with the matrix switch and a PC through an interface , the PC is equipped with test software, the test software controls the automatic test resources to output the power supply or signal that meets the requirements through the bus, reads the output signal of the circuit board under test, and at the same time controls the matrix switch through the bus to make the corresponding pin type in the socket correspond to the one being tested. When working, add the interface definition of the circuit board in the database of the test software, the system will automatically switch the function of each pin of the socket, output the signal or power that meets the requirements, and automatically switch the output port of the circuit board Connect to the corresponding equipment of the automatic test resource, and display the parameters and waveforms of each output port of the circuit board on the software interface. The invention has the advantages of strong expandability, strong versatility, high degree of automation, convenient operation 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.

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 control; secondly, its versatility is poor: traditional testing instruments are often aimed at single or fixed test equipment for several circuit boards. When a new circuit board is to be tested, a new circuit board tester needs to be developed Instruments and test equipment for different circuit boards are not interchangeable, and testing and design require specialized technicians

Therefore, traditional manual testing methods and simple self-made testing equipment will be difficult to meet the increasingly high testing requirements for circuit board testing
