The firecrackers of the Year of the Pig is getting closer and closer, and the beginning of the last work week also announced that the dog is coming to an end.
Folklore is good - "Twenty-three, sweet gum"; twenty-four, sweeping the house; twenty-five, frozen tofu; twenty-six, stewed big meat; twenty-seven, slaughter; twenty eight, put the face "Who said that now is the new year is getting more and more light?
Who said that the traditional ruthenin does not matter? In our hardware house, "everything is DIY", and the traditional annual customs can also be the case.
In order to let everyone go through the year, it can take the charm of traditional folklore in modern technology, we decided to launch six topic questions around the folk customs starting in the small year, let you buy it, you can play well. !
I believe that many small partners have cleaned the house in the intermittent renewal to clean the houses, but they should be used to clean all kinds of home equipment, but be careful. Some things can be cleaned, especially for electronic products, such as our daily entertainment. Chassis motherboard.
Can the motherboard cleaning?
I believe that in daily life, many small partners have such a common sense, and after crashed into the water without waterproof, immediately pull the battery to shut down, and dry for a long time, there is a chance to recover the loss.
This also makes many users have wrong misunderstandings: Wash some electronic products with water without power, there is no great harm. In fact, this is wrong.
The vast majority of our daily tap water presents weak acid or weak alkaline, easy to corrode the circuit board, which in turn causes damage to the circuit, plus if the drying is not thorough, will cause the motherboard to short-circuit - burn the motherboard.
The cleaning motherboard we have seen in some maintenance agencies is a dedicated washing water or secondary distilled water, which is mainly to ensure that the water is cleaned without electrostatic ions.
But can you really have a main board?
Is the motherboard was washed? --practice
In order to avoid experiments, we have caused a loss of irreparable efforts to our daily work. We aailed a flashlight FM2A88X-ITX motherboard as our test body. When the motherboard was got, it was already dusty, although there was no superior picture. But it is obviously a ITX motherboard that has not been cleaned for a long time.
Detect motherboard
In order to make the entire experiment process more convincing, we have the first time of the motherboard, first test the motherboard. Connect each part of the wiring, turn on the power, and smoothly light down the motherboard (in the figure, the CPU fan is not fixed).
The motherboard is corrupted in which the VGA video interface is corrupted, and we select the HDMI interface to connect the display.
BIOS enters smoothly, through the BIOS screenshots. We can see that our platform uses the AMD A10 7890K processor + ASRock FH2A88X-ITX motherboard and is equipped with 4GB DDR3 1600MHz memory.
Connect the display, the system is operating normally.
This means that although this motherboard is covered with dust, and some interface is damaged, it is still working properly.
Before cleaning the motherboard, we have to do the disassembly accessories, including CPUs, memory, network cards, and onboard batteries. As for why you don't clean a CPU and motherboard, then we will give an answer.
Water washing motherboard
In order to reduce the long-term erosion of the motherboard, we choose the flowing tap water to clean the motherboard, in order to be more close to the home environment, we also support the toothbrush as an auxiliary tool. The figure shows the dust of the main board CPU area.
↑↑↑ Clean the motherboard power supply module.
↑↑ 清 Clean other electronic components around the motherboard.
↑↑↑ Finally, it was cleans the motherboard backplane.
Achievements show that by using the push of water and the cleaning of the brush head, the final motherboard surface is new, reaching the fundamental purpose of our cleaning motherboard.
Dry motherboard
To ensure that the motherboard can dry as much as possible, we choose a sunshine outdoor environment, using wind and heat to cool the motherboard, this is also to make our home environment, of course, if it saves the loss as much as possible We can also use a hairdryer to accelerate the evaporation of water vapor in the motherboard. (Lifting a strange)
Finally, we chose a place with sunshine, laying a good water absorbing, drying.
And record the drying time with a watch.
Test results
We took a total of nearly six hours before and after, including hair dryers to assist water vapor evaporation. Remove the partial fixed check to find the motherboard to dry (if the specific drying time is subject to the situation, it will ensure complete drying for six hours).
All supporting hardware products, including NIC, memory, and CPU before installation.
After the power is turned on, the platform is running normally.
Screenshot in the main interface of the system.
Performance Testing
We use the Cinebench R15 to perform performance tests, the purpose is not to verify its platform performance, but to prove that our water wash motherboard rear platform does not only do it only.
Small science
Why is CPUs not easy to clean? At present, the mainstream consumer CPU on the market is mainly from Intel and AMD, and the two CPUs have a certain difference in appearance.
First, we first say that our AMD processor used today, we all know that the most identity of the AMD processor is a pin.
And our most worrying in the process of installing the AMD CPU is the needle damage, not to mention the process of using the liquid to clean the CPU, it is easy to cause the pin to bend, so it is not recommended to wash the AMD CPU.
Although the Intel CPU has canceled the pin design, in order to balance the internal and external air pressure, Intel's CPU will leave a "pore" when the cover is capped, not completely sealed. It is easy to cause liquid to enter without discharging.
Through our experiments today, we found that the motherboard can also be used after the washing, then the memory can you? If the memory is also water washing, according to the same processing method as we today.
However, it will damage the surface of the label and other information. In addition, if we buy memory strips with heat dissipation vests, in order to ensure that moisture can be completely dried, users should remove the heat-dissipating vest to clean.
Summarize
The above is the whole process of the experiment. By testing we found that the motherboard is not to use after the online cleaning is, it will not be used after the online cleaning, but if the circuit does not destroy its circuit, make sure the motherboard is completely dried and equipped. The possibility of use.
Of course, we did not use a large number of motherboards to test, and the conclusion did not have 100% reliability, so it was not recommended that ordinary users were easily tried. If you are a loved DIY user, and there is a motherboard has been warranty, then ...
