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…
