PCB board repair refers to the bringing the physical damage which has been done to a PCB-namely pad or trace lifting, laminate repair, eyelet replacement to name a few-back to a point to where the printed circuit board can function based on the original design requirements. Printed circuit board repair skills and processes require lots of patience and a high degree of hand-eye coordination.
Restoring Medical Instrument Electronic Circuit Board is an important means to ensure the technical performance of medical equipment is intact and normal use. During the use of Medical Instrument Electronic facility, due to the movement of materials, there will inevitably be continuous changes in technical conditions, or the impact of power supplies, environmental temperature and…
General Electric Power Supply Circuit Board Maintenance starts from appearance observation which will help us find out a obvious issue over the board: The first step is to observe whether General Electric Power Supply Circuit Board has been artificially damaged, mainly in the following aspects: ① Whether the circuit board has been dropped, which has…
Fresenius Hemodialysis Equipment Motherboard Fixing can be diversed into various methods includes: First of all, Checking the fuse:Many medical instrument circuit boards failure is caused by fuse issue since most of them have fuses to prevent the components on the circuit board from being burned out when the current is too high. Therefore, if a…
Bellco Dialysis Machine CPU Control Board Rework happens after the malfunctions of whole device is used for a period of time, a large amount of dust will be adsorbed on the surface of the Machine CPU Control Board. This dust will cause the components on the circuit board to fail to dissipate heat, resulting in…
HITACHI OASIS MRI Mainboard Repairing will inspect the power supply system to the mainboard which could probably have greater possibility of failure since there are 6 modules will be applied. The A+/A- ports of the six power modules are disconnected from the circuit and then turned on to measure the resistance of the A+ /…
HITACHI Magnetic Resonance Imaging Controller Card Troubleshooting starts from circuit board repairing without schematic diagram and the Symptom of HITACHI Magnetic Resonance Imaging malfunctions is : “MR unit error” is reported when the machine starts. The machine does not start normally. Fault check: First check the gradient amplifier of the MRI electronic card unit according…
Fixing Siemens X-Ray Generator Circuit Board Module starts from failure judgement analysis, through fault detection program and measurement methods: first of all, Find by fault detection program is the easist way to access one, under normal circumstances, when Siemens X-Ray Generator fails, most of it can be detected by its own program to determine the…
Troubleshoot Medical Equipment Circuit Board has becoming more and more important in the process of medical equipment maintenance service; In a sense, the use of medical equipment largely depends on the level of development of the hospital and the support of financial resources.
