In the design and maintenance testing of circuit boards, Electronic Printed Circuit Board Troubleshooting is a complex and time-consuming problem.
In the past, in many companies, an effective solution for troubleshooting electronic controller cards of equipment was often not found. The traditional method is that some experienced engineers rely on a series of test equipment (such as: multimeter, oscilloscope, frequency meter, logic analyzer, etc.) and some necessary printed circuit board schematic drawing and circuit diagrams which are normally absence from original manufacturer.
Adopt the ancient method of “teachers and apprentices” to deal with the failure of equipment electronic circuit boards. But with the development of information science and technology, the emergence of various new electronic components, the increasing diversification of electronic products, and the need of some manufacturers for technical confidentiality, this “old way” has been challenged.
As a result, some new integrated circuit PCB board maintenance and test products have emerged at the historic moment, and they are trying their best to solve the equipment electronic circuit board failure and some of the following problems:
1 no circuit schematic diagram and related information needs to extract from PCB board;
2 The engineer has no corresponding experience;
3 Mass production of similar products for different reasons;
4 Offline exclusion must be changed to offline and online comprehensive exclusion;
5 Go further automatic detection of networking;
