Reverse Engineering PCB Board Anti-Interference Layout Diagram, generally speaking, should conform to the principles of electrical interference and easy heat dissipation between the devices, and this process can help to extract the circuit diagram from original PCB board when the absence of necessary documents to make improvement of circuit board original layout diagram, there are…
Data Acquisition System PCB Board Reverse Engineering can be applied for improvement of design modification, since the quality of the Data Acquisition System PCB Board design has a great influence on the ability to resist interference. Therefore, the design of the Data Acquisition System printed circuit board is not simply a layout arrangement of devices…
Siemens Hemodialysis Electronic PCB Board Reworking can be seen that the appearance of each component is normal, and the resistance of each component is measured in turn. The forward resistance of LED1 is about 30KJ, the forward resistance of D34-36 is about 6Kft, the forward and reverse resistances of voltage regulators Z14, Z16 and triode…
Toshiba Hemodialysis Circuit Board Maintenance process and principle analysis: Check that there is no obvious burnout on the circuit board, restart the machine, the phenomenon is still the same. Clean it with a brush, absolute alcohol, etc., and check that there is no obvious abnormality in the joints. Turn on again. It is measured that…
Rework Integrated Chip on the Broken GENERAL Computer Tomography needs to desolder and replace the chip prone to failure, it can be replaced with a chip socket, which is convenient for future chip replacement or elimination test of unstable chip failure. Some chips are inexplicably damaged, mostly due to electrostatic discharge. The general chip antistatic…
Commonly Seen Faulty Issue in Troubleshooting Computer Tomography PCB Board include Migratory or unstable faults are mostly caused by poor device performance, poor temperature characteristics, and poor contact of device pins. For devices suspected of degraded performance, use a memory oscilloscope to carefully observe and compare the changes in the logic waveform. Whether the waveform…
Maintain Medtronic Computer Tomography Motherboard Functional failures are mostly caused by chip damage. The interface part of the general circuit board is most vulnerable to the impact of harmful pulses of the power grid, lightning, and industrial spark pulses. The online tester can be used to easily test the interface circuit chip and determine the…
Repair Non-Functional Computer Tomography Circuit Board will take a lot of trouble to further find the specific faulty chip on the device. The failure phenomena on the circuit board are ever-changing and different, but they can be summarized as follows: the performance of integrated circuits; resistance-capacitance components deteriorates, the unstable performance, and the function fails;…
Siemens Computer Tomography Controller Card Chip Level Repairing is a deep-level maintenance, which has certain difficulties, and its high technical content requires certain conditions. The maintenance instruments should be compatible with the current development level of Siemens Computer Tomography equipment. The methods of using multimeters, ordinary oscilloscopes, and off-line device testing in the past have…
Exploring Philip Computer Tomography Mainboard Chip Level Maintenance has a positive significance for expanding the technical level of Computered Tomography PCB board maintenance and reducing maintenance costs. At present, Philip Computer Tomography equipment is rapidly and widely popularized in China. County and district hospitals in economic development areas are almost all equipped with CTs of…
