Siheyuan: Craftsmen of a Great Country
Chapter 497: The well-prepared first bird
The person in charge of the circuit production of the project team is electrician Lao Zhang
Researchers who are able to get the opportunity to operate in the project team are definitely skilled and experienced workers.
But this was the first time for him to make such a small circuit board.
Therefore, we were extremely careful and used microscopes and Qiming Machine Tool's matching machine tools to manufacture small machine tools.
Even though it's already October, the sweat is still pouring down my face.
There was a researcher standing next to him, wiping his sweat.
As soon as the sweat comes out, wipe it off immediately.
Both of them are very dedicated to their work.
One of them was concentrating on looking at the machinery and circuits in front of him, and the other was concentrating on looking at the other's forehead, and neither of them noticed Jiang Chen's arrival.
The others had just greeted them when Jiang Chen made a hushing gesture, asking everyone not to disturb the two people's work.
It took him two hours to complete a circuit on a normal-sized circuit board that could have been completed in ten minutes.
The completed single circuit board is about the size of a thumbnail.
It is finished, but as for the workmanship and aesthetics, let's not talk about it.
Originally, this kind of thing would be easy and efficient for Luo Xue to do.
But Luo Xue was destined to be transferred away to research lithography machines, so the project team had to get used to life without Luo Xue in advance.
He had just finished when the colleague who was wiping his sweat said excitedly: "Lao Zhang has done it, he has done it."
This shout attracted the others to gather together.
Although the production of this miniaturized circuit board is not a major achievement, it is the first step in practical operation, and everyone wants to come and see it.
The fingernail-sized circuit board became the focus of the entire audience.
Lao Zhang took a deep breath and whispered, "It's done, it's done. Let me test it first."
He felt that he should not have made any mistakes.
He took out a multimeter, connected it carefully, and stared at the pointer of the watch.
One second, two seconds, three seconds.
The pointer didn't move at all.
Old Zhang was anxious and patted the multimeter: "How could this happen? Is the watch broken?"
Jiang Chen said, "When you were at the second interface of your line, your hand shook and you seemed to have touched the thin copper wire, but you couldn't stand such a toss."
The limit of the size resolution that the human eye can directly observe is between 10 and 50 microns, and the diameter of the copper wire is already within this range.
Ordinary eyes can't even see him.
But Jiang Chen not only saw it, he also saw Lao Zhang touch it, and everyone was a little unbelievable.
Perhaps this is the difference between geniuses and ordinary people.
Since Jiang Chen had already taken the initiative to speak, everyone also greeted him: "President Jiang"
Jiang Chen waved his hand, signaling everyone to be polite.
Lao Zhang was stunned: "Really? Let me see."
He went to the microscope again and found the second interface.
Then use the tool to gently pick up the copper wire.
I want to ask why the copper wire under the microscope rose up in response and was not under any force at all.
Lao Zhang said, "It is really broken here. I am sorry, sorry, it is my fault. I am sorry, President Jiang, and I am sorry to all the comrades."
Jiang Chen was stunned: "Why are you apologizing?"
"Failure is the mother of success. Scientific research is about using countless failures to exchange for one success. So it is normal for an experiment to fail. Don't take it to heart."
"When we were researching converter steelmaking, we added oxygen too quickly and the furnace exploded with a bang. The entire Sangang Group was shaken and almost caused a loss of life."
"What's your point? Just start over!"
Of course, that accident was caused by Lu Yuehua's excessive haste and could have been completely avoided.
Scientific research allows failure, but does not accept mistakes.
With Jiang Chen's comfort, Lao Zhang felt more at ease and said slowly, "Actually, there's no need to start over. I'll try a different copper wire. It should be repairable."
After saying that, he carefully removed the copper wire and replaced it with a new one.
Perhaps because there were too many people watching, he became more nervous, and it took him ten minutes to simply replace a piece of copper wire.
After receiving the call, Lao Zhang did not start the test immediately. Instead, he turned around and asked, "President Jiang, did you find any other mistakes just now?"
Jiang Chen shook his head: "No, you should test it first!"
Only then did Lao Zhang nod and connect the multimeter.
The needle finally moved.
Lao Zhang was a little excited: "It worked. It really worked this time."
Everyone responded with warm applause, which was both affirmation and encouragement.
Old Zhang said, "Damn it, I've lived for decades and never thought that one day I would do such a delicate job. This is much more tiring than Zhang Fei threading a needle."
Everyone laughed.
At this time, a researcher asked: "Dean Jiang, using copper as a conductive material is good in every way except that it oxidizes too easily."
"Do you have any good solution for this?"
Perhaps it is because Jiang Chen has always been the leader of this Internet project team and has also participated in the research, so everyone has become dependent on him.
So the researcher asked this question directly.
Jiang Chen frowned and said, "You are a researcher. Do you have a solution? Why don't you ask me?"
The researcher also realized that there was something wrong with his question, so he quickly changed the topic and said, "President Jiang, what I meant is that after our discussion, we found that copper and gold are more suitable conductive materials for integrated circuits."
"Copper is more easily oxidized, and gold is too expensive. I can't make up my mind for the moment, so I want to ask Dean Jiang for his opinion."
Jiang Chen finally understood.
This isn't asking a question, it's just trying to show off.
There are always such people in every era, who rush ahead of the team and take unfinished plans or results to report, communicate and consult with leaders.
He doesn't have any bad intentions, he just wants to show how hard he works and how seriously he works in front of his boss.
This kind of person is usually half-hearted. If he doesn't show his ability now, he may not have another chance to show his ability later.
Most teams don't like this kind of people.
And they are often used as the first to come out.
Just now, this person saw Lao Zhang in the limelight and felt a little envious, so he wanted to seize the opportunity to grab some of the limelight.
As soon as this person said this, the other researchers all looked unhappy.
Some people even sneered and looked down on them.
Generally speaking, people who do research are simple and straightforward, and any dissatisfaction will be written directly on their faces.
They don't bother to steal the limelight themselves, but they also don't want others to steal it.
These are all the results of the team's research. Why should you be the one to take the limelight?
Coincidentally, Jiang Chen also didn't like this kind of person. He said calmly, "What answer do you think I should give you? Copper or gold?"
"Or should I just tell you to use gold because I like gold? This is scientific research, a serious issue."
"This" the researcher looked unhappy and didn't know what to say.
Some researchers around couldn't help but laugh out loud.
Jiang Chen said slowly: "In this case, the correct approach should be to first consider solving the copper oxidation problem and calculate the required cost."
"Then they compared the cost with the user money, and finally came to me with this comparison data to discuss the final plan, instead of coming to me directly without any preparation."
"Without any evidence, how can I give you an answer?"
The man returned to his workstation and brought a piece of paper over: "President Jiang, I have compared these two materials."
"Using copper as the raw material, the cost of anti-oxidation treatment is not high, but it can only ensure that there is no need to worry about oxidation within five years. There is still a risk of oxidation after five years."
"If gold is used as the material, there is no need to worry about the quality guarantee. The life of the connecting wire is the same as the life of the integrated circuit. The only problem is that the cost is too high."
"It's just that I don't know how long the life of an integrated circuit is, so I asked Dean Jiang for his opinion."
After saying that, he handed the paper with the results and cost estimates to Jiang Chen.
