The Red Era, the Opening University Speech

Chapter 205 Have you forgotten that you are getting married soon?

Li Mu nodded slightly and continued, "Then do you think that if I design a new type of motorcycle using a V-twin engine, will it be helpful to the army?"

"Yes, of course, it's very helpful!" Zhao Canjun was stunned for a moment, then said excitedly: "Although the Happiness 250 is durable and powerful, its shortcomings are also obvious."

"The worst thing is the difficulty in starting in winter, the noise is too loud, and the load capacity is insufficient."

"But I'm sure you can solve this problem, right?"

He looked at Li Mu, his eyes full of anticipation.

Compared with the single-cylinder V-twin, the motorcycle they independently developed has made great progress.

If it really works, it will be of great significance to the troops.

"It shouldn't be a big problem. Since you, Brother Zhao, think it's useful, I'll give it a try." Li Mu said with a smile.

He almost forgot that there was a motorized infantry force behind him.

If we can develop it in advance, the counterattack against India may not even take 32 days. We can defeat them in a week and force them to move their capital overnight.

With the goal of completing the task within a week, Li Mu spent the entire afternoon concentrating on designing the blueprints for the motorcycle.

The civilian ones are very simple, sturdy and durable and can pull things, which can meet the needs of most people. There is also a space reserved for adding a sidecar, which can accommodate one more person, making it much more convenient.

As for military use, we need to consider it carefully.

Durability and high anti-interference performance are a must, otherwise it will not be able to adapt to the harsh environment and conditions on the battlefield.

In addition, it must be small in size, light in weight, and fast in speed, and it must be able to carry weapons. Unlike military bicycles which are only used for communication, military motorcycles are used to carry people for charge, so stability is also very important.

Li Mu also referred to some of the more famous military motorcycles during World War II, such as Emperor M's Harley WLA, Daying's Norton Big 4, Sandezi's BMW R75, etc.

The vehicle type is naturally a classic sidecar. The sidecar can be equipped with a machine gun and a four-speed gearbox so that it can be used on various terrains.

……

Li Mu worked until about 11 o'clock in the evening, and a thick stack of manuscript papers piled up in front of his desk before he completed the design of the military motorcycle.

Theoretically, the maximum horsepower of this military motorcycle can reach 30, which is suitable for various combat environments. The maximum speed can reach 95km/h, and the side seat can be removed, so it is very light and can be carried by three people.

The cooling system uses a combination of water pump, water filter, radiator tank and fan.

The water pump is responsible for circulating the coolant to various parts of the engine, and the water filter is used to filter impurities in the coolant to prevent clogging.

The cooling water tank and fan are used to accelerate the cooling process.

This design is a bit complicated, but it can effectively extend the service life of the engine and improve its performance.

Of course, there is room for further optimization in terms of horsepower and top speed, but Li Mu does not think it is necessary.

For example, horsepower. The limit of the V-twin cylinder is 185 horsepower, but high performance also means high cost. It is unnecessary to spend so much money just to make it run faster.

After these are done, a new motorcycle, one for civilian use and one for military use, will be produced.

……

Li Mu stood up from his chair and stretched himself. He couldn't help laughing when he thought that our soldiers would be able to ride the motorcycle he designed to beat the Indians in the future.

"The design is ready." Seeing this, General Zhao, who had been watching Li Mu designing for the entire afternoon, showed excitement on his face.

"Okay." Li Mu nodded gently. "The next step is to see if the engine we assemble tomorrow can be successful. If it can, there won't be any major problems with the two motorcycles."

After getting his confirmation, General Zhao's face became even happier, and he even had the urge to run to Hongxing Steel Plant with the drawings immediately.

Fortunately, reason helped him calm down.

Even if he ran away at this time, there would be no one else in the factory who would do it.

"Can I, can I take a look first?" General Zhao took two steps to the left and right, unable to contain his excitement, and asked.

Li Mu smiled and said, "Of course, Brother Zhao, you just watch first. I'm going to sleep first. If you have any questions, you can ask me tomorrow."

After saying that, he lay down on the bed.

General Zhao didn't care when he saw this. He immediately took the design drawing, blocked the light from the desk lamp towards Li Mu, and then began to look at it impatiently.

However, he didn't know that Li Mu was not sleepy at all, but a "ding~" message alert sound rang in his mind.

Closing his eyes, he opened the chat page and saw the message from Ask:
"Lee, I'm big baby!"

“Picture of airplane.jpg.”

“Selfie.jpg.”

"Congratulations on starting a new journey!" Li Mu sent his blessings and felt sincerely happy.

He was indeed very happy. He opened the WIFI list and randomly scrolled through it, and he saw several WIFIs with the suffix of "research institute".

He even saw the Atomic Physics Laboratory of Jianqiao University, which made him so excited that he clicked on it directly. However, when he saw hundreds of GB of files and only one bar of signal, he had no choice but to give up.

"The person who's going to pick me up will be here soon, Li. I'll contact you when I reach my destination." Ask replied happily.

Li Mu said: "Okay, I'll wait for you."

Ask will only study and communicate in this place for 15 days, and he must choose the most valuable materials to download.

For example, the atomic physics laboratory, although it smells good, it must be eliminated first.

He is now studying applied physics. Although it is not impossible for him to cross over to other fields, it is very eye-catching that he did not work on emerging semiconductors but instead worked on atomic energy, and published his results so quickly.

First of all, we need to find information on semiconductors, and finally we can directly solve the mass production problem of distributed projection lithography machines.

Secondly, there are various things that can generate huge economic benefits after they are produced.

Finally, there is no end. How much can be downloaded in 15 days? At most 130G, which is not enough.

Li Mu first circled a range for himself to avoid being overwhelmed by the choices when the time comes.

……

After about an hour or two, Ask still hadn't responded.

Li Mu waited and waited, but finally he couldn't resist the sleepiness and fell into a deep sleep.

The next day, he jumped up from the bed with a hint of regret in his eyes.

How could he fall asleep? Every minute and every second of downloading time is so precious!
While regretting, he opened the chat page, ready to make up for it in time.

However, when he opened it, the chat page showed a message from Ask: "Li, Da Ying is really messy. My suitcase was robbed as soon as I left the airport."

"After much difficulty, a kind-hearted person helped me track it down, but I found myself lost again."

"I will immediately..."

...The third message was not sent yet. Li Mu guessed that the phone might have been stolen.

"I accidentally fell asleep last night. How are you? Contact me when you're okay." Li Mu was a little worried about Ask's safety. After replying the message, he thought for a while and opened the WIFI list.

The WIFI is bound to Ask, not the mobile phone, so through this, it can be basically determined whether he is safe.

The first WIFI on the list is the database of the Jianqiao City Security Brigade of Jianqiao County, Daying.

Seeing this, Li Mu felt relieved temporarily.

After waiting for a while and seeing no reply from Ask, he looked through the WIFI list again and found that only a few libraries' WIFI were close.

Thinking that he would probably not be able to finish downloading it, he sighed softly and started to wash up and exercise as usual.

……

After coming back from exercise, seeing that Ask still hadn't sent a message, Li Mu didn't wait any longer and quickly went to the semiconductor laboratory.

Just as he parked his bicycle downstairs, Wang Shoujue and Huang Xinhua came over with smiles on their faces.

"Director Wang, Professor Huang, I rested well yesterday, you don't have to worry about me." Li Mu said hurriedly, fearing that they would ask him to go back.

He looked at it specially this morning. Although he didn't sleep much yesterday, he waited for Ask with his eyes closed, so he didn't have dark circles under his eyes today.

Huang Xinhua smiled and said, "It's good that you know how to rest, but we didn't come to you to talk about this. We have something happy to tell you."

"Good news?" Li Mu looked at the expressions of the two and had some vague guesses.

Huang Xinhua continued: "Yes, the mass production process problems of our distributed projection lithography machine have basically been solved. Next, as long as we overcome the technical difficulty of packaging, we can achieve the final large-scale mass production!"

"That's great!" Li Mu waved his fist excitedly.

Once the distributed projection lithography machine is put into mass production, it cannot be overemphasized how great its significance will be for Xia's semiconductor industry. You know, this kind of optical technology will not be eliminated even after another sixty or seventy years!
Without the mass production of distributed projection lithography machines, his reference document on the development of the semiconductor industry is just empty talk and will never be realized.

Thinking of this, Li Mu immediately said: "I will apply to join the packaging technology team immediately!"

He couldn't wait a moment and wanted to solve the problem of mass production.

"No, have you forgotten that you are about to get married?" Huang Xinhua shook his head and Hao said with a smile.

Li Mu's lips moved and he counted the days. It seemed that there were indeed less than two weeks left.

Wang Shoujue couldn't help but laugh when he saw this, and said:
"Just continue to instruct, the speed won't be too slow."

"You are getting married soon. You can't just get married on the same day and come back to do research at night."

"Even if you agree, we can't agree. What will Wang Ya think? Even if Wang Ya supports you, what about her family?"

At the end, he sounded very serious, as if he was really afraid that Li Mu would do this.

"You do have a point." Li Mu nodded, but added: "But I am confident that I can complete the encapsulation technology before I get married."

Wang Shoujue and Huang Xinhua looked at each other and said, "We are willing to believe in your ability, but we should be prepared for the worst. What if it is not completed by then?"

They have seen Li Mu's enthusiasm for scientific research many times. Except for eating and sleeping, he is almost unshakable.

Hearing this, Li Mu said:

"Director Wang, Professor Huang, don't worry. If I fail, I will put my research aside for the time being and wait until I get married."

"After all, marriage is a once-in-a-lifetime thing, and I won't make a mistake on this matter."

"Besides, if we can finish the research before the wedding, it will be a great thing, right?"

……

laboratory,
Distributed projection lithography machine mass production packaging technology research and development team.

Everyone was busy conducting experiments.

Packaging technology is a technology that packages integrated circuits with insulating plastic or ceramic materials.

At present, the packaging technology used in domestic semiconductor integrated circuits mainly adopts dual in-line packaging.

Two rows of pins are inserted into a dual-in-line powder structure chip socket. The matching circuit board needs to undergo a perforation process. Generally, the maximum number of pins is 64.

This packaging method is large in size, has a strong antenna effect, and has poor automatic mounting and alignment capabilities. It obviously cannot meet the needs of mass production of distributed projection lithography machines.

After thinking for a long time, Li Mu found Huang Xinhua and said, "Professor Huang, I think we don't need to continue upgrading the dual in-line packaging technology. Instead, we should look for new packaging technology."

"Oh, new packaging technology? Wait a minute." Huang Xinhua's eyes lit up. He immediately stopped all the experiments and called everyone over.

"Okay, keep talking," he continued.

Li Mu paused for a moment, then said:
“I think it would be possible to package the IC without having to insert the pins into the holes, just by placing the IC on one side of the PCB and soldering it on the same side.”

"This method reduces the difficulty of printed circuit board design and greatly reduces its size."

"The most important thing is that the chips soldered in this way are difficult to remove without special tools and have good safety. I call it surface mount technology."

"Also, I want to try the multi-chip packaging technology, putting multiple chips in the same package to achieve collaborative work of multiple chips..."

……

After he finished speaking, everyone was silent for a while, digesting what he said.

These two technologies appeared after the 80s and were still not outdated at the time when Li Mu was there. If they were solved, there would basically be no more difficulties in packaging technology in the future.

After a long while, while the professors were still deep in thought, Huang Xinhua had already raised his head and said with a smile: "Your two development ideas are good. Surface mounting is of great significance to the improvement of production efficiency and the realization of automated production."

"Not only that, I just calculated carefully and found that we can save a lot in terms of cost, materials, energy and time!" a researcher followed.

Other experts and professors also began to praise.

Although it is only an exploratory idea at present and has not even undergone an experimental verification, their long-term trust in Li Mu has made them feel that these two technologies can most likely be realized.

Li Mu listened to everyone's praise, waved his hands, and said helplessly: "Professor Huang, and all the experts and professors, I just proposed an idea, and it has not been realized yet."

"But with your idea, I think we are not far from success!" A professor said with a smile, causing everyone to laugh.

When did Li Mu fail in any research and development idea?
After everyone laughed, Huang Xinhua said:

"Okay, now that we have a direction, let's start experimenting and see how to achieve it."

“We will try to master new packaging technology before he gets married.”

"When the time comes, it will be a double celebration. Both the wedding banquet and the celebration banquet will be held in our semiconductor research institute!"

"Okay!" After hearing this, everyone gradually put away the smiles on their faces and immediately threw themselves into the experiment.

However, after Huang Xinhua finished speaking, he secretly found Li Mu.
