Technological power starts with upgrading lenses

The next morning, when Kangchi arrived at the silicon wafer equipment R\u0026D center, he found that Yan Hui and the others had arrived at the company a long time ago. They had even transported the polishing machine to the assembly workshop in advance and were dismantling the casing.

Kang Chi smiled and walked up to greet them: "Why are you here so early?"

Yan Hui looked back at Kang Chi: "What do you think?"

"Uh..." Kang Chi looked at the panda eyes on Yan Hui's face and said speechlessly, "Have you been up all night?"

"The main reason is that you were too tight-lipped about the sale yesterday." Yan Hui laughed bitterly, and then led Kang Chi to the polishing machine, "We are about to dismantle the outer casing, and let's see if all of it is dismantled next, or... Only remove a certain part?"

"Well, let me take a look first."

After Kang Chi finished speaking, he took a flashlight and carefully observed the internal structure of the polishing machine.

In fact, the structural design of the polishing machines are very similar. The main difference lies in the accuracy. If this machine is like Yan Hui said, even every part is accurately copied, then logically there should be no problem. of.

Half an hour later, after Kang Chi briefly understood the structure, he pulled up a stool and sat down to take a breath. At the same time, he asked Yan Hui: "So, how much of the technology have you mastered by following the gourd?"

Yan Hui thought for a moment before replying: "About seventy or eighty percent."

"Oh, if my guess is correct, then you are very lucky." Kang Chi pointed at the polishing piece, "Take off the grinding table of the polishing machine and take a look."

After receiving the instruction, Yan Hui immediately started working with a technical team of more than ten people.

Looking at the scene in front of him, Kang Chi was almost moved to tears.

In the past, he would have had to do the disassembly and assembly of such precision equipment by himself. Just dismantling a grinding table would probably take him a whole day.

But now, he only needs to sit comfortably and watch, and he can feel the rapid increase of the progress bar.

It's simply wonderful.

With the close cooperation of more than ten people, two hours later, the grinding table of the polishing machine was dismantled and placed on the workbench, exposing various parts below.

Kang Chi immediately walked up and after a brief observation, he pointed at a small black cylindrical part and asked Yan Hui: "Do you know what this is?"

"Strong magnetic coil."

"What does it do?"

"Fixed grinding table?"

"Then why not just use screws?"

"Hmm... maybe the screws are loose and causing the countertop to vibrate?"

"Then why don't they just weld them to death?"

"This..." Yan Hui was stumped and began to fall into deep thought.

In fact, this cannot be blamed on Yan Hui. There are so many parts in a polishing machine. Usually, when working in reverse, the core parts are analyzed and understood first. These non-core parts are all analyzed by mid-level and low-level researchers. manufacture.

You can't even let Yan Hui ponder over the principles of shell design...

"Let me remind you again, apart from these sixteen strong magnetic coils around the edges of the grinding table, does this polishing machine have other magnetic coils?"

"Of course there are, and there are many." Yan Hui said without hesitation, "Each robotic arm must be driven by a motor, especially the largest grinding disc. There is a big one..."

As he spoke, he suddenly stopped, as if he thought of something.

"you mean……"

"That's right, this thing definitely does more than just play a role in strong magnetic adsorption and fixing the table." Kang Chi said with certainty, "It probably also involves the adjustment of the magnetic field of the entire equipment to constrain the grinding disc drive motor. The slight shock caused!”

"Now ask the software engineer to check the driver again and find the voltage setting program for these 16 strong magnetic coils. If my guess is correct, their voltage values ​​must be different."

As Kang Chi explained, Yan Hui's heart beat faster and faster, and even the veins on his forehead bulged a little...

He had a strong premonition,

Kang Chi is right;

They are getting closer to the truth!

Yan Hui suppressed his excitement, turned to a researcher and said, "Gong Zhang, hurry up and call the software engineering team over!"

"Um."

Soon, software engineers rushed over with a bunch of equipment, and then, under the command of Yan Hui, began to analyze and search for the device drivers.

The work was a bit big, and it wasn't until around four o'clock in the afternoon that they finally found a line of code hidden in a small corner.

"The voltage values ​​are indeed different!"

"Is this...is it really the reason for this set of electromagnetic coils!?"

"Mr. Kang, you are so amazing!"

"..."

Hearing the surprised comments from the engineers, Yan Hui couldn't help but look at Kang Chi with a complicated expression.

"Congratulations, you already have the answer." Kang Chi said with a smile, "The next thing you have to do is to quickly analyze the magnetic field of the equipment, and then debug the voltages of these 16 sets of strong electromagnetic coils."

Yan Hui nodded: "I didn't expect that the problem would arise here..."

Kang Chi patted him on the shoulder and comforted him: "Every secret must be sparse, especially for this kind of precision equipment. Every screw may contain a mystery, and you can't cover everything."

"But didn't you do it?" Yan Hui smiled bitterly, "It took only three experiments to discover the key to the problem... No wonder they all say you are a monster..."

Kang Chi just smiled and didn't make much excuse on this matter.

Otherwise, the blow to Yan Hui would be even greater...

In fact, even without Kang Chi, Yan Hui might have discovered this problem sooner or later, maybe tomorrow, maybe next month, maybe two years...

Research on this kind of thing is so metaphysical. Sometimes issues that you think are not critical happen to be the core issues. Researchers often waste a lot of time and energy on this...

Once you have your goals and direction, the next thing is easy.

Kangchi once again realized the importance of a professional team. He originally thought that when he came to Sixin, he would have to start from rubbing the parts by hand and reassemble a polishing machine like before.

As a result, Sixin's research and development of polishing machines has reached the point where it is just a step away. With just a push from Kangchi, the matter was easily solved.

And all he has to do is sit aside and supervise (fishing)...

With the hard work of Yan Hui's team day and night, it took only two days to complete the overall magnetic field debugging of the polishing machine and start the actual test after debugging.

As the robotic arm places the roughly ground silicon wafers into the six grinding discs, the silicon wafers begin to rotate rapidly and come into contact with the grinding table.

The entire polishing process lasted about ten minutes, and then after cleaning, the inspection process began.

At this moment, the entire R\u0026D team couldn't help but hold their breath and stared at the inspector closely.

"No scratches above 0.14nm were found on the surface of any silicon wafer."

"Silicon wafer surface flatness...1.22nm RMS!"

As the inspector reported the test results with a trembling voice, the whole laboratory immediately boiled!
