Hearing the discussion, Xing Baohua headed towards the classroom around the corner.
A dozen or so students were gathered around two computers on the table, clearly not taking the computers seriously. There was no air conditioning in the room, and I didn't see them wearing white lab coats or shoe covers.
One of the students was using a flathead screwdriver to remove screws.
People around him craned their necks to watch him disassemble the machine. One of the students said, "This is my cousin Chen Shuoyue, a third-year student in the School of Computer Science at Beijing Institute of Technology. This guy next to him is his classmate, just call him Brother Wang."
Many people were envious after hearing the introduction, and some even applauded.
Xing Baohua stood close to the perimeter, and because of his height, he could see clearly without having to squeeze forward.
The casing had been opened, revealing the internal hardware. At this moment, Chen Shuoyue, who was holding a screwdriver, said, "Is the microscope that I asked you to prepare ready?"
Everyone was focused on the computer, and no one noticed Xing Baohua on the periphery. At this moment, he was puzzled, thinking that Xing Baohua was going to explain computer hardware knowledge to everyone.
Need a microscope?
This kind of thing isn't used for routine repairs. Even if a solder joint is broken, at most a magnifying glass would be used. Anything requiring a microscope is generally beyond the capabilities of ordinary repair personnel; it requires specialized equipment.
For example, if a chip is really broken, you can basically only look at it with a microscope. You can see where the problem is, but the cost of repairing it is higher than replacing it with a new one, and it's not worth the effort to repair it.
Xing Baohua wanted to check the nameplate on the host computer because he hadn't seen it after disassembling it. He wanted to look at the logo on the monitor, the IBM logo.
Xing Baohua is familiar with all IBM models! But these two look a bit off!
There are fakes made of this stuff?
When someone brought over a small microscope, Chen Shuoyue said again, "All the machines in your computer lab are slow, which is probably caused by hardware. You've reinstalled the system and cleaned up junk files on these two machines, so theoretically they're like new machines, but they're still generally slow. Especially when reading data, the waiting time is long."
I suspect two possible causes: a problem with the CPU or a problem with the memory. For all computers and even electronic products, the most practical repair and maintenance method is the simplest process of elimination.
The reason for bringing two machines is to test by replacing parts between them. There are only a few parts; by simply plugging them back and forth, we can eliminate possibilities step by step.
Xing Baohua gave a thumbs up, saying that if this kid were to open a computer repair shop in the newly established Zhongguancun, it would definitely be a hit.
Anyone who can repair hardware is a master.
Then the other person said, "A microscope is mainly used to look at the internal structure of the CPU and the memory chips. As long as you carefully look for the bad parts, you can find the problem."
Xing Baohua gave a thumbs up in his heart. The method was correct, but he was a bit more naive than him!
It's not impossible to look at the internal structure of a CPU, but opening the package will ruin it. Even if you can see which area is broken, it doesn't mean you can put it back together!
Especially the packaging process, how do you package it? Unless he has a replacement CPU and memory.
Xing Baohua became interested and saw Chen Shuoyue start by removing the memory stick and polishing the two round protrusions with a small file.
They really dared to make a move!
Perhaps they dared to dismantle it like that because they had spare parts. Xing Baohua could only sigh inwardly, thinking that it was even more ferocious than he had been back then.
In no time, the memory chip casing was polished out. Chen Shuoyue pointed to some metal dots on it and said, "The structure of memory is the chips inside. I won't go into the theoretical stuff; you can read the books yourselves when you get back."
After saying this, Chen Shuoyue placed the polished memory under a microscope for observation.
Most people didn't dare to say a word and just watched him fiddle around. At that moment, Xing Baohua's phone rang.
Upon hearing the bell, the surrounding students all turned to look at him, only to find that there was suddenly an extra person. Fortunately, Xing Baohua was also young and assumed that he was also a student from the same school who had come to study computers together.
Xing Baohua nodded awkwardly to the students, picked up the phone, and walked out of the classroom.
The call was from Su Ya, and Xing Baohua told her to wait for him in the car for a while.
When I returned after hanging up the phone, I heard Chen Shuoyue say, "I checked the memory; the internal structure is intact. It shouldn't be a problem with the memory. Now let's start polishing the CPU and take a look at its internal structure."
At this moment, Xing Baohua still had her arms crossed, looking at the other person with great interest.
Using a file is the most violent method. Even if the Rice Lab wants to disassemble a CPU, it has to use a micro grinder to grind it little by little so as not to damage the internal structure.
However, some surfaces of a file are quite rough. If you don't control the force when you push and pull, you can damage the internal structure.
The transistors inside are so damaged that they are unbearable to look at even under a microscope!
Fortunately, Chen Shuoyue was gentle, rubbing and grinding slowly, and even blowing away the dust she had ground off.
It took about ten minutes to grind off the top layer of skin, and only then could you see the fine lines exposed on top.
“Underneath the circuitry are transistors, and another layer needs to be polished before they can be peeled off to reveal their structure,” Chen Shuoyue said.
"If the cup is intact, does that mean our experiment was a waste of time?" one of the students said.
"It's not a complete waste. At least we now know how the core components of a computer are structured, and we can reproduce their structural diagrams under a microscope," Chen Shuoyue said.
Xing Baohua interjected, "I want to know how you're going to put it back after damaging the core components like this?"
"Didn't we agree beforehand that we'd pool our money to buy the CPU and RAM? Oh! Which department and class are you from? I've never seen you before," one of the students asked Xing Baohua.
