"Is there any problem? After the assembly is completed and your technicians will find out soon?" Zheng Yucheng was too lazy to say to someone like Chen Tongan. "They are only responsible for ensuring the accuracy of machinery and assembly."

"This is your equipment." Chen Tongan heard the dissatisfaction in Zheng Yucheng's words.

The entire workshop was very quiet. I don’t know when the lights in the workshop were already on.

"Then who can make a desk lamp, this light cannot be used, and I can't see clearly."

"Then who, pour a glass of water!"

"Who, pinch my shoulders, why are you so unsighted to see me?"

In the entire workshop, except for the occasional sound of the old men, no one heard.

In the eyes of the nine-level fitters who work hard, there are only the files in their hands and the parts under the files.

"Director Zheng, it's already past eight o'clock now, otherwise they would let them take a rest and eat something?" Chen Degui was a little worried that the old men's bodies would not be able to withstand it.

Zheng Yucheng shook his head and said with a wry smile, "They won't leave this workshop before they finish it."

"What should I do if I have a meal?"

"Let the people in the cafeteria make it well and send it over. Don't make it too hard for them to digest. In addition, don't add too much salt, don't add MSG..." Zheng Yucheng said to Chen Degui, "In addition, let's get some quilts over, some of them are going to rest."

"This..." Chen Degui was a little embarrassed. "What should I do if I sleep here and get cold?"

As required, I got food and delivered it to you, no problem.

"If you don't bring a cup, they will sleep in a dress. If you really feel sorry for it, just beside them and bring a bed for them each." Zheng Yucheng said.

"No?" Chen Tongan could not imagine the living conditions of these people.

"Their technology is strategic. At the same time, in their eyes, there are only parts and tools in their hands, and there is no other. It is useless for anyone to persuade him." Zheng Yucheng sighed.

Outsiders can't imagine this situation at all.

"In our unit, they have a special workshop, which is twice as big as this workshop. Each person takes at least two to three technical workers from level 7 or above to work hard; at the same time, more than twenty people are divided into two shifts to be responsible for their lives..." Xie Kai said quietly.

Outsiders simply cannot understand.

If there is a way, for example, if there are top-level processing equipment like foreign countries, it does not require manpower to slowly consume it, and it will not be like this.

This is also the reason why the country attaches so much importance to CNC systems and CNC machine tools, and why they can get 30 million yuan in funding just by creating a CNC system. Later, they provided 1,000 CNC systems to obtain 60 million yuan in funding from the first machine department.

With just one set of CNC system technology and one thousand CNC systems, 404 received 90 million yuan in funding, of which the profit was 60 million yuan.

Zheng Yucheng and others did not keep guarding each other. This was a hard time and the technicians who had been with him had never thought that these old men were so crazy about working, they didn't go to the cafeteria to eat, and they slept in the workshop when they were sleepy. When they woke up, they got up and continued to work.

But they have to accompany them.

"Be prepared, use these lithography machines to re-production, and then see how the chip performs." Xie Kai told Hou Weigui, Wang Jingzhong and others. "The production process of five microns and one micron is completely different."

There are nine-level fitters from 404 responsible for high-precision processing and final assembly in machinery, and professionals from Fengcheng Optoelectronics Research Institute are responsible for debugging the entire lithography machine. With the production process of Factory 691, and the production of 68,000 chips, there is no such big problem.

Even if the performance varies and the scrap rate is higher, the previous problems should not occur.

While the workshop was intensively repairing second-hand equipment, the technicians in Factory 691 also began intensive preparations.

When the manufacturing process changes, the silicon substrate of the chip will also change, and even the mask plate will have to be remanufactured.

Until the third day, all the parts were completed, and both lithography machines produced in Germany could be used again; the microscope produced in Switzerland had to wait until the microscope was manufactured, which would take too long.

"I really can't believe that the parts they produced can be comparable to those of the original ones!" When the final debugging was completed and various data players were tested, Chen Tongan looked surprised.

"This is just a replacement part, and none of them have been overheated. The materials are the same. Only the accuracy can be achieved and cannot be used for production." Mr. Wei said calmly. "Even if the spare parts we produce reach the progress, the accuracy will decrease due to continuous friction during the large-scale manufacturing process..."

"We know this. Mr. Wei, thank you for your hard work these days." Zheng Yucheng understood.

Materials and manufacturing processes all determine the accuracy maintenance time and service life of mechanical parts.

"After the physical and chemical analysis is released, we will process another batch of backups, and there will be nothing we can do here. The drawings can be determined now, and we will try our best to process at that time." Mr. Liang said.

What they are talking about is the facts.

In the current restoration, since the materials were not heat treated and did not analyze what materials were originally used on the equipment, they were just used to process materials that were close to their performance based on their experience.

The service life will definitely not be very high.

"Even if it is repaired frequently, it is not a big problem. As long as we can use such a manufacturing process, we can copy it first. With more quantities, we can continue to study higher manufacturing processes." Chen Tongan said to Mr. Liang.

"Arrang everyone to have a good rest." Zheng Yucheng ordered Chen Degui.

These old men have not had a good rest these days. Now they wait for the results of physical and chemical analysis, look at the materials used in each component, and then make a batch and replace it before they can be fully used.

"The mask version and so on have been prepared again..." Hou Weigui reported and asked when the sample trial production will start.

The photolithography process requires the silicon wafer surface cleaning, drying, base coating, spin coating of photoresist, soft drying, alignment exposure, post-drying, development, hard drying, etching and other processes, and the most core of which is alignment exposure.

The circuit on the sample is copied to the processed silicon wafer through a lithography machine, and then developed to corrode unnecessary areas.

The units that can produce chips have different manufacturing processes in main equipment, but the processes are the same.

"How long can the sample be produced?" What Xie Kai cares most about is the time issue.

"I will see the integrated circuit board tomorrow morning, but the packaging does not have a mold..." Hou Weigui said.

Packaging technology is also a must, just a circuit board, and it cannot be used at all.

If it is dusty or something, it is easy to cause damage to this circuit.

"There is no hurry to package for the time being. Just make sure that the chips we produce are comparable to the 68,000." Xie Kai said.

"Okay." Hou Weigui nodded and did not leave. Instead, he looked at Xie Kai and Zheng Yucheng with some embarrassment, looking like he was reluctant to speak.

"Just say anything." Zheng Yucheng looked at Hou Weigui, "We are not unreasonable people."

"The main purpose of this kind of chip is to be used in game consoles and exported to the international market. If Motorola people know it, it will cause a devastating blow to the entire industry. Their chips are all patented." Hou Weigui has inspected the market in the United States and understood the market.

Domestic never care about patents.

Especially for military systems, there is no patent at all.

After all, if you want to apply for a patent, your technical characteristics must be disclosed to the patent office of the applicant country.

"Don't worry about this matter, Motorola can't find us at all. As long as it can be produced, your unit has to start applying for patents from the United States, Japan and other countries!" Xie Kai said with a smile.

"Isn't this their design drawing?" Hou Weigui was puzzled. "When the time comes, the lawsuit will be filed..."

"Don't worry," said Xie Kai.

"What patent is applied for? Disclose the technology to foreign countries? This is a product they have embargoed us!" Zheng Yucheng said dissatisfied.

"We are embargoed because we don't. Once we have this kind of thing, there will naturally be no value for embargo." Xie Kai said with a smile, "When we produce it, we can completely find foreign packaging factories to package it!"

Xie Kai knew better than anyone else that they had made their scrapped production lines and modified them to the point where they could be used, which does not mean that they could make breakthroughs in China.

"Like CNC system? Once we have it, they will not limit it?" Zheng Yucheng understood a little, but was a little confused.

"When we have it, they continue to blockade, forcing us to make progress faster..." Xie Kai couldn't tell Zheng Yucheng about some truth.

Anyway, as long as foreign countries do not block the domestic market, they can get it in large quantities, so there will be no problem.

High-end chips are needed in China.

Early the next morning, Hou Weigui, whose eyes were covered in blood, took out an integrated circuit similar to the 68,000 chip to find Zheng Yucheng and Xie Kai.

"Did you detect it? How is the performance?" Xie Kai asked.

"According to our detection, the data processing capacity is about 7% higher than Motorola's 68000 chip, and the power consumption is about 11%. The previous heat dissipation problem was lower than expected..." The expression on Hou Weigui's face was obviously questioning such a result. "This is not the design drawing of the 68000 chip."

"Of course not! Many masters have improved the circuit and optimized the design! There are not so many transistors!" Xie Kai said proudly in his heart, but there was no reaction on the surface, and he said, "What if it is, it's enough to use it. Under the current circumstances, how much can it be provided in a month?"

"If two lithography machines and other equipment can be used, our silicon wafer supply is sufficient and we can produce 20,000 such chips per month."

"Under the current conditions." Xie Kai just wanted to know how much it could be produced now.

The 404 base’s demand for high-performance chips is too huge.
