Siheyuan: Starting from a fitter

Chapter 126 Clean Room
"Old Li, come and sit down." Wu Liankui quickly got up and helped Li Guocheng make tea.

Li Guocheng shook the radio in his hand, smiling and listening to the Peking Opera clip of "Taking Tiger Mountain Out of Strategy".

"What, the chip is done?" Wu Liankui suddenly thought of something, his eyes filled with enthusiasm.

Li Guocheng was speechless and just shook the radio again.

"Brother Li, Uncle Li, show me quickly." He was smart and had already guessed the result.

Li Guocheng didn't take Qiao anymore, opened the back cover, and pushed the radio to Wu Liankui.

Wu Liankui looked at the circuit board in the box carefully, and there was a rectangular thing on it that he had never seen before. He knew that this was the chip Li Guocheng was talking about.

He touched it lightly with his hand and found it very strong.He picked up the radio, turned it over, and started to tune the station. Hearing the clear voices of storytelling, music and opera, Wu Liankui was completely addicted.

After a while, Li Guocheng grabbed the radio. Under Wu Liankui's surprised eyes, he let go of his right hand. The radio fell to the ground and turned over.

At this time, the radio made a rustling sound, and seeing Wu Liankui was heartbroken.

"What are you doing?" Wu Liankui was confused.

He quickly leaned over to pick up the radio and wiped the non-existent dust with his hand.After careful inspection, I found that there was no major problem, so I started to adjust the station, and soon the radio came out with beautiful sound again.

Looking at the smiling Li Guocheng, Wu Liankui seemed to have figured out something.

"Can you make this radio?" Wu Liankui asked tentatively.

Li Guocheng nodded without saying anything.

When Li Guocheng designed it, he took into account reliable fixation and anti-drop design, and even the battery has a reliable buckle.

Wu Liankui gave Li Guocheng a thumbs up.I picked up the radio and wanted to throw it to the ground. I tried several times but didn't dare to drop it.

Li Guocheng slapped the hand that was holding the radio. In his exclamation, the radio fell to the ground again and he turned several somersaults in succession.

Wu Liankui picked up the radio again with curiosity on his face and found that except for some scratches on the casing, everything was normal when tuning the radio.

"So, can production be fixed?" Wu Liankui is very interested in manufacturing.

Li Guocheng nodded, "There is no problem in setting production, but we can't make qualified chips now."

"Why?" Wu Liankui was a little frustrated.

"I carved these chips by hand. The production efficiency is too low. I can't keep producing chips. Moreover, the laboratory environment is not very good and the yield rate is not high."

Li Guocheng turned on the cheating mode.The reason for locking the door is to prevent others from discovering the secret of the secret realm.

"You must have a way, right?" Wu Liankui was very smart and asked Li Guocheng, too lazy to worry about it.

"Zhang Zhijing, Yan Jiefang, and Zhou Xiaojuan have already started research. I will ask them about their progress later. But if we want to increase the yield, we must build a dust-free workshop."

"Clean workshop, what is that?"

"I discovered this when preparing chips and transistors. In the afternoon and evening, the yield rate is extremely low, but in the morning before going to work, the yield rate is much better." In order to explain the dust-free workshop, Li Guocheng had already thought up an excuse.

"Later, I observed carefully and found that the dust in the laboratory was the least in the morning. Then I splashed the laboratory with water in the afternoon and found that the yield rate was even higher than in the morning. Therefore, dust is the natural enemy of yield rate."

Wu Liankui asked thoughtfully, "Is the investment big?"

"I've thought about it. I'll build a new small workshop, just 500 square meters. It'll be fully enclosed, and add air inlets and outlets filtered by multiple layers of gauze. I'll have a changing room when I go in, leave my outer coat in the changing room, and walk through with bare feet. Go to a blowing channel, enter another changing room, put on one-piece work clothes, wear a mask, and wear work shoes."

Looking at the curious Wu Liankui, Li Guocheng continued: "Install some spray humidifiers in the workshop. In this case, it will be a simple dust-free workshop."

Li Guocheng had no choice but to make it like this under the current conditions.

Wu Liankui calculated in his mind for a while and felt that the investment was really small and it could be done.

"Hasn't it already begun to build a lathe branch factory? It's not far to the east of us. Let them form a small team. As long as there are enough materials, it will be built in ten days." Li Guocheng continued to lie.

Wu Liankui thought for a while, picked up the radio, stood up and left, "Let's go, Old Li, go find Director Li."

The process was very simple. Director Li looked at the radio in his hand and agreed without any hesitation, and directly approved the construction of a 1000-square-meter dust-free workshop.

After discussion among the three people, they decided to only manufacture the core chips of radios in the future, and transfer the radio technology to the outside world, which would be a good time to gain some funds.

"Don't worry, a special fund has been allocated for the manufacturing method and equipment of the single crystal ingot that was submitted last time, which is enough to build a dust-free workshop and follow-up research and development costs." Li Huaide waved his hand grandly, everything is under control.

"When applying for the construction of a machine tool branch, the Capital No. [-] Machine Tool Factory also wanted to use the Shuguang II lathe. I argued hard and made them speechless at that time."

Li Huaide got excited when he talked about this matter. This was the first time he had mentioned it.Wu Liankui's flattery immediately made Director Li smile.

How could Li Guocheng be so LOW, "Without you at the front, our laboratory would not be where it is now", Li Guocheng looked serious.

"Hahahaha..." Li Huaide happily invited the two of them to drink.

In fact, the problem is far more serious than this. Not only does the No. [-] Machine Tool Factory want to cause trouble, the Capital Precision Instrument Factory also has its eye on the Precision Laboratory of the Steel Rolling Mill and insists on acquiring it.What's even more speechless is that Wei Haibin and his factory actually wanted to transfer Li Guocheng to rub parts on the grounds of military supplies.

They applied to the ministry many times and received support from some department leaders. Finally, they reported to the minister, but were rejected.

Lunch is relatively simple, just 4 dishes and one soup, and the only meat dish is old hen stewed with mushrooms.Accompanying me was Deputy Director Wu from the Security Department.

The old hen stewed with mushrooms and casserole may be too heavy, and the one who served it was Si Zhu.When he saw Li Guocheng, he became very enthusiastic and asked him to go back to the courtyard to sit down when he had time.

Li Guocheng also responded politely, and the scene was harmonious and friendly.

After a quick meal and some business exchanges, Li Huaide emphasized Deputy Director Wu and asked the Security Department to strengthen the security of the laboratory.Deputy Director Wu patted his chest and promised that nothing would go wrong.

When leaving, Li Huaide patted Li Guocheng and Wu Liankui on the shoulders and said, "When will you report to the ministry? I will listen to your laboratory. The rolling mill will give you all its help. You must work hard to get a gift as a gift on the party's birthday." A great gift."
