"Xiao Gong, today is a bit rushed, when the plan is confirmed, we will send you a quotation in advance."

Li Huaide was also depressed, "How do I know the cost, this price is impossible to talk about."

"Xiao Gong, do you have any requirements for the shape of the circuit board?"

"The smaller the better, and the maximum is 10x10 centimeters," Xiao Gong expects.

"There is no problem, we will design according to 5x5 cm first, and then modify it if there is a problem," Li Guocheng said firmly.

"Great, so that you can put it on the side wall of the gyroscope, save the control compartment, and be able to carry more fuel," Xiao Gong said happily.

"Do you have big gyroscopes?" In Li Guocheng's impression, the gyroscope is only the size of an egg. In later generations, children played with spinning tops all over the street.

"It's not that big! It's only the size of a basketball, which is much smaller than Big Brother. This is our second-generation product," Xiao Gong said proudly.

Li Guocheng had a little impulse to hold his forehead. Such a big gyroscope, it's proud!

Forget it, I just understand the principle of gyroscope, but how to make it, I don't have the ability yet. If you do machining on the basis of the current gyroscope, you should be able to reduce the volume.

"Xiao Gong, as you know, the full name of our laboratory is precision laboratory, and the technology we started with can be precision machining. If you believe our lab, you can consider let's miniaturize the gyroscope."

Xiao Gong thought for more than ten seconds, "Now that we are also in-depth cooperation, I will go back to apply first, and we will talk about how to cooperate when there is a result."

"Okay, Xiao Gong. Back to the topic, how many templates do you need? ”

"5 pieces are enough", Xiao Gong said excitedly.

"Then it's decided, at most three months, you can get the sample," Li Guocheng said firmly.

"Great, we are getting acquainted with the operating system and programming language of the Dawning 103 computer. Everyone liked it very much, and the transistor computer we imported from West Germany last year was still a paper tape input, and now there is a 103 type, and everyone doesn't use that one.

The Pangu programming language is more powerful, not only in Chinese, but also in writing habits and interfaces are very friendly. You don't have to compete with machine language anymore."

"If you like it, if you have any needs, just mention it, we will continue to optimize and make progress according to everyone's requirements," Li Guocheng said modestly.

The same sentiment occurred in the office of the big leader.

"Lao Zhao, this report is a bit extravagant, I actually went to the newspaper office to print it, I have to see if the content in it matches the paper."

An energetic old man habitually bent his chest with his right arm, and patted the manuscript on the table in front of him with his left hand. The old man on the other side smiled and said nothing.

After reading the first page, the big leader raised his head and looked at Old Man Zhao, "No, this is not your Old Zhao's writing style, your previous drafts are all the last to draw a conclusion, and the front is all foreshadowing."

This manuscript writes the conclusion of the whole text on the first page, and the following is a discussion of the conclusion, and the level is very distinct. Tell me who wrote this manuscript for you."

"I'll tell you after you finish the conclusion", Zhao Lao smiled even more happily.

When the big leader read the conclusion, he did not stop, but continued to read, and the back was divided into several subsections, each subsection began with the conclusion, followed by the supporting data and information of the conclusion.

After reading it in one go, the big leader closed his eyes and pondered.

"Is the Dawning 103 computer and the Pangu programming language really so advanced?"

"After about half a year of use, each unit has different applications, especially in automatic control, some experts predict that there will be great development.

In the past, the computer was too large and the power consumption was too high, although there was an automatic control theory, but it was difficult to use it in practice. Now with the Model 103, many projects are possible.

Before I came, I received a report from the research institute that they are working with the rolling mill laboratory to develop a microcomputer that can be used for missiles," said Zhao proudly.

"Okay, the leadership is also more concerned about missile research and development, in the past I heard that it has been stuck in the navigation part, if it can break through, many problems can be solved. Then we'll have a real fist to threaten our enemies.

No matter how good a knife is, it is only valuable if it is pierced in the chest of the enemy.

You have a good grandson-in-law! I hope you will be able to nurture this seed well, and this big tree of his, will bear more fruit," he said."

"Don't worry, we will! By the way, this printer is also a good thing", Zhao Lao hurriedly promoted.

"It's a good thing, but what we lack most now is foreign exchange and powerful weapons. Without foreign exchange, we can't bring in equipment, and without powerful weapons, we can't protect our wealth and land."

"Now the rolling mill is working on CNC machine tools, and with the world's leading computer, we can also exchange technology or products with the West in the future."

"Well, we Chinese are the smartest, most hard-working, and most patient, in the 20 years since the founding of the People's Republic of China, we have built a basic industrial system on the ruins, and now we have the most advanced semiconductor technology, and there are successors!"

"Yes, I seem to have felt the splendor and splendor of the future of China."

The second elder's face was full of sacredness, and he was silent for a long time.

Two months later, Li Guocheng completed the design of the op amp and was engraving the mask board.

"Brother Li, do you think it can be done this time?"

Yan Jiefang cautiously walked in front of Li Guocheng with a circuit board, this is already the design diagram of his third version of the missile control board, Li Guocheng was not satisfied with the first few times, each time it was either that the area was too large, or that the signal integrity layout was not good.

But the area is large and he understands, but the signal integrity, he can't understand anything, and finally, he finally understands that the connection must be short, and the multi-layer board must be considered.

This is the first time he has successfully made a 4-layer board, and it was only after Zhou Xiaojuan who drilled the tin plating and finally solved his problem.

When he showed it to Li Guocheng, Li Guocheng sat up in shock as soon as he shone at the light.

"I didn't expect it, Jiefang, you really came up with a multi-layer board, how did the vias be tinned?" , Li Guocheng was very happy, but he didn't expect that when he was about to do it himself, Jiefang actually gave him a surprise.

"The potion that Zhou Xiaojuan helped prepare", Yan Jiefang saw that Li Guocheng was happy and knew that this version should be a success.

"You're all good! Is there a test impedance? Li Guocheng asked.

The impedance meter is an old impedance machine dismantled by Li Guocheng in West Germany, and then imitated, optimized the design, and remade it, and the accuracy far exceeded which one in West Germany.

"Tested, the via impedance did not exceed 0.1 ohms. In addition, in order to reduce the area, a double-sided device layout was adopted, and the NOR FLASH was attached to the back."

"This is the best and most advanced design at present", Li Guocheng is very sure.
