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 PCB control board is found to be faulty, the fuse on it must be checked and eliminated first. If the fuse is only burnt out, the electronic pc board can be restored to normal when the fuse of the same specification is replaced.
Secondly is to find obviously damaged components, carefully look at the components on the Fresenius Hemodialysis Equipment Motherboard to see if any are damaged or burned. Generally, it is easier to see capacitor expansion or cracking, triode breakdown and burnout, or a resistor burning out. Replace components of the same model or other replaceable models if available;
Thirdly is finding Welding and Corrosion
Sometimes the medical equipment printed circuit boards of some devices are not good enough because of the process. After a period of use, the pins of some components may be soldered or the working environment of the machine is relatively humid, which may cause corrosion on some parts of the board. These problems are easy to find with a magnifying glass. At this time, you only need to add soldering to the soldered area and reconnect the corroded area.
Forth is Adjusting the adjustable resistor
If some fresenius mainboard fails during use, the consequences are unimaginable. Therefore, when it is regularly tested, it should be tested according to the actual use situation and the frequency of failures.
Generally, a circuit board problem can be detected by adjusting the adjustable resistor. When the mechanical equipment fails, it is necessary to be able to detect the instability of the voltage and make accurate judgments by observing the data results by checking the schematic diagram or layout drawing created from circuit board . However, before this, the relevant data must be marked as reference data when detecting errors. The purpose of doing this is to better avoid repeated tests, leading to inaccurate results.
