Cutting-edge technology: Starting with individual stealth equipment

Lin Chuan looked at the computer screen, arms crossed: "No matter what, these theoretical data need to be verified through experiments. What if it really is like that? And my intuition tells me there will be a surprise."

Huang Chongwei, standing next to Lin Chuan, turned to look at him and said, "Are you really going to verify this? I've looked through it, and it'll probably cost a lot of money."

Jiang Miaolan also said, "The company has just been established, are you sure you want to mess things up like this?"

Lin Chuan said confidently, "Great discoveries are often so accidental. I trust my intuition. That's it. Let's do this next. My mind is made up."

Seeing that Lin Chuan had already decided to do it, no one dared to object anymore.

Cheng Siyuan and his colleagues also wanted to verify this, because after reviewing the theoretical materials, they found no obvious scientific flaws.

Maybe it really will work.

If it really works out, that would be incredible.

Compared to Skyworth Technology's original business, it's nothing.

"The core of the skin is the precise stacking of seven graphene films. The thickness and angle of each layer must meet the requirements. Once the angle is deviated, different physical properties will be produced. After stacking seven layers, it is necessary to achieve precise control of electromagnetic waves in different bands."

At this point, Lin Chuan turned to Huang Chongwei: "You are the most suitable person for the task of creating the skin substrate and the laminated structure. I'm entrusting it to you."

"These process requirements are too demanding!" Huang Chongwei complained, then said, "But they're not impossible. I need a high-end atomic layer deposition system."

Lin Chuan shook his head and said, "We can't buy it. Even if we could, we couldn't afford it. A set of equipment costs more than 800 million yuan. The company's current cash reserves will be depleted after buying this."

He then added, "Don't go for something so extravagant. The company is in a startup phase with limited resources. Modify it yourself. This magnetron sputtering + chemical vapor deposition composite process, to put it simply, is to alternate between two reactions in one chamber."

Huang Chongwei glanced at the schematic diagram in the document and nodded: "That makes sense. We can find an old magnetron sputtering machine, remove the original target stage, and install gas pipelines and heating devices ourselves."

"Then comes the sensor array and control circuit." Lin Chuan turned to look at the three people next to Guo Tao.

"This module is yours. Guo Tao, you and the other two handle it. The skin surface needs to integrate a large number of micro sensors. Each sensor collects light intensity data in four bands: red, green, blue, and infrared, and transmits it to the processor in real time through microcircuits."

Guo Tao stated bluntly, "This density of array cannot be made using existing PCB manufacturing processes."

Lin Chuan pondered for a moment, then said, "Then let's use flexible circuit boards, roll-to-roll technology, with a linewidth of 10 micrometers. We can make the sensors into a regular grid, with each 16×16 sensors sharing a single readout circuit. The density will be reduced, and the performance will definitely decrease, but it will be sufficient for initial verification."

"How much will it drop?"

"The theoretical matching rate drops to around 85%, but the human eye can hardly distinguish them."

Guo Tao pondered for a moment and added, "The sensor itself is also a problem; you can't buy one that small on the market."

"We can do it ourselves," Si Mingche interjected. "We can use the technology of CMOS image sensors to shrink the pixel unit to 5 micrometers x 5 micrometers, find a MEMS foundry to make a set of photomasks, and it should cost around 300,000 to 500,000 yuan."

Lin Chuan nodded upon hearing this: "Okay."

Cheng Siyuan, who was standing next to him, said, "Leave the background matching algorithm and the embedded software to me. I'll handle that part."

Lin Chuan explained, "Each pixel on the skin adjusts its color and brightness in real time based on the spectral information of the surrounding environment. This is extremely complex to implement because the surrounding environment of each pixel is different, requiring the construction of a dynamic environmental field model."

Upon hearing this, Cheng Siyuan pondered and said, "If this algorithm were to run on a general-purpose processor, the power consumption would be outrageous."

Lin Chuan immediately said, "Then let's build a heterogeneous computing architecture, matching each pixel unit with a very simple analog computing circuit to perform preliminary feature extraction, and then setting up a digital signal processor at regular intervals to perform fusion calculations."

He then looked at Cheng Siyuan and asked, "Can you write it down?"

Cheng Siyuan replied, "Yes, but I need three months and three people."

Lin Chuan said, "No, it has to be done in a month and a half. I'll give you five people for lab-scale verification. We don't need full resolution; just make a 10x10 sample first."

Cheng Siyuan said, "That's more like it, otherwise it would be impossible to do it in such a short time."

Lin Chuan nodded and said, "The algorithm can be simplified, but the underlying architecture must be correct."

He then wrote down a list.

It includes a total of 37 items such as vacuum pumps, gas flow controllers, magnetron sputtering targets, and precision motion platforms.

After glancing at the list and confirming that everything was in order, Lin Chuan handed it to Zhang Wei.

"I'll leave the purchasing to you."

Zhang Wei glanced through it and then nodded: "OK."

The company hasn't officially opened or started operations yet, but Lin Chuan has already assigned tasks today; that's his execution ability.

……

Two days later, it is advisable to open for business.

Lin Chuan specifically consulted the Chinese almanac and chose an auspicious day.

Although he is a tech enthusiast and not superstitious, he mainly treats it as a traditional ritual to bring good luck.

The opening ceremony was very simple.

A red banner hung at the company entrance, with the words "Grand Opening" written on it.

There were no flower baskets, no guests, and not even firecrackers.

At this moment, sixteen people were in the office. Everyone set off a firework, and Zhang Wei brought over a case of beer and a few bags of peanuts, which he put on the table in the common area as a celebration.

"Come, let's toast to the deep blue!"

"Homage to the deep blue!"

Everyone raised their glasses. Lin Chuan, holding a can of beer, looked at his partners who had followed him from Skyworth, smiled, and took a big gulp.

Just as the atmosphere was getting lively, there was a knock on the door.

Jiang Miaolan was closest to the door. She walked over and opened it, but the smile on her face froze for a moment.

The person standing at the door is Qiu Zhanfeng.

He was wearing a dark gray suit, carrying a gift, and sporting a standard business smile.

"Wishing you a prosperous opening!"

Qiu Zhanfeng walked in with a smile, quickly scanned the office, and handed the gift to Jiang Miaolan.

"I've come uninvited, please don't be offended."

The atmosphere in the office suddenly turned cold.

When Zhang Wei saw him, his face immediately darkened. He was about to speak when Lin Chuan stopped him with a look.

"You're too kind." Lin Chuan stepped forward with a smile. "Have a seat."

Qiu Zhanfeng didn't sit down; he stood there and looked around again.

With a smile on his lips, he nodded approvingly to himself, saying, "The location is well chosen, Deep Blue Technology. The name is also good, it has depth."
