Repair Intracardiac Hexagram Mainboard by IC Online Tester can improve maintenance efficiency since it has a learning function, an offline test function, an LSI (large-scale integrated circuit) inspection and analysis function, and a VI (volt-ampere characteristic) curve analysis function.
Test and compare the logic function of the integrated circuit chip through a large number of library files in the computer, and determine whether it works normally, making online testing of the integrated circuit PCB board maintenance possible. Using the online tester can greatly reduce the scope of maintenance and improve circuit board fixing efficiency;
Although there are many types of medical electronic equipment PCB board malfunctions at present, and the failures are also strange, it is not difficult to analyze complex circuit boards. It is not difficult to find that it is often composed of power supply functional unit, CPU processing unit (if the MCU has been damaged, it is necessary to extract embedded code from locked microcontroller), ROM, RAM storage unit, A / D, D / A conversion unit and various I / O input and output units.
The following article uses the online tester and combines the experience of repairing circuit boards to introduce the basic rules for refurbishing faulty controller circuit cards.
