"Is there a problem, wait until the assembly is done later, and your technicians will know it soon after they are adjusted?" Zheng Yucheng said too lazy to say to someone like Chen Tongan. "They are only responsible for ensuring the accuracy of the machinery and assembly. ”

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

The whole workshop is very quiet, I don't know when, the lights in the workshop have been quietly turned on.

"Then who, get a table lamp here, this light can't work, I can't see clearly. ”

"Who's that, pour a glass of water!"

"Then who, pinch my shoulder, why are you so blind?"

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

In the eyes of the serious ninth-level fitters, there is only the file in their hands and the parts under the file.

"Director Zheng, it's already past eight o'clock now, why don't you let them rest and eat something?" Chen Degui was a little worried that these old men's bodies would not be able to bear it.

Zheng Yucheng shook his head and said with a wry smile, "If it's not done, they won't leave this workshop." ”

"What about eating?"

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

"This ......" Chen Degui was a little embarrassed. "What if you sleep in here and get cold?"

I went to get food as requested, and there was no problem.

"If you don't bring a cup, they'll sleep together. If you really don't want to go, just next to them and move a bed for each of them. Zheng Yucheng said.

"Isn't it?" Chen Tongan couldn't imagine the living conditions of these people.

"Their technology is strategic, and at the same time, in their eyes, there are only parts and tools in their hands, and nothing else. It is useless to persuade anyone. Zheng Yucheng sighed.

Outsiders can't imagine such a situation at all.

"In our unit, they have a special workshop, which is twice the size of this workshop, and each person has at least two to three skilled workers above level 7, and more than 20 people are divided into two shifts to be responsible for their daily ......," Xie Kai said quietly.

Outsiders simply can't understand it.

If there is a way, such as the kind of top-level processing equipment abroad, there is no need to rely on manpower to slowly consume, and it will not be so.

This is also why the state attaches so much importance to CNC systems and CNC machine tools, and why they can get 30 million funds only for a set of CNC systems, and they later provide 1,000 sets of CNC systems from a machine department to get 60 million funds.

With only one set of CNC system technology and 1,000 sets of CNC systems, 404 has obtained 90 million funds, of which 60 million are profits.

Zheng Yucheng and others have not been guarding, this is a bitter technician who has been with them, where did they ever think that these old men work so crazy, do not go to the canteen for dinner, sleep in the workshop when they are sleepy, wake up and get up and continue to work.

But they have to be with them.

"Get ready, these lithography machines are fixed, and you can re-produce them with these, and then we'll see how the chips perform. Xie Kai said to Hou Weigui and Wang Jingzhong and others. "The production process of 5 microns is completely different from that of 1 micron. ”

There is a ninth-level fitter from 404 who is responsible for the high-precision machining and final assembly of the machinery, and there are professionals from the Fengcheng Optoelectronics Research Institute who are responsible for the debugging of the entire lithography machine, plus the production process of the 691 factory, and then the production of 68000 chips, there is no such big problem.

Even if there is a difference in performance and a higher scrap rate, the previous problem should not occur.

While the workshop was intensively repairing second-hand equipment, the technicians of the 691 factory also began intense preparations.

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

By the third day, all the parts were ready, and both German lithography machines could be used again, while the Swiss ones had to wait until the microscope was manufactured because the microscope inside was broken, which took too long.

"I really can't believe that the parts they produce can be comparable to the original!" When the final debugging was completed and various data hands were tested, Chen Tongan was pleasantly surprised.

"It's just a replacement part, it's not heat-treated, it's the same material, and you can only determine if the accuracy can be achieved, and it can't be used in production. Wei Lao said calmly. "Even if we are on track with the parts we produce, the accuracy will be reduced due to constant friction during the mass manufacturing process......"

"We know that. Old Wei, you've worked hard these days. Zheng Yucheng understood.

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

"When the physical and chemical analysis comes out, we will process another batch for backup, and there will be nothing for us here. The drawings can now be determined, and the process will be as good as we can when the time comes. Liang Lao said.

What they say is the truth.

The current restoration, because the materials are not heat-treated, and there is no analysis of what materials were originally used on the equipment, but according to their experience, they are processed with materials with properties that are close to those and suitable for these locations.

The service life will certainly 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 imitate it first, and if there are more of them, we can continue to study higher manufacturing processes. Chen Tongan said to Liang Lao.

"Arrange for everyone to have a good rest. Zheng Yucheng instructed Chen Degui.

These old men haven't had a good rest at all these days, and now they are waiting for the results of physical and chemical analysis, looking at the materials used in each part, and then making a batch and replacing them before they can be fully used.

"The mask and so on have been re-prepared......," Hou Weigui reported, asking when the sample trial production would begin.

The lithography process needs to go through the processes of silicon wafer surface cleaning and drying, priming, spin coating photoresist, soft drying, alignment exposure, post-drying, development, hard drying, etching, the core of which is alignment exposure.

The circuitry on the sample is copied onto the treated silicon wafer by a lithography machine, and then developed to etch out the unwanted areas.

The manufacturing process of the units that can produce chips is different on the main equipment, but the process is the same.

"How long does it take to produce a sample?" Xie Kai is most concerned about the matter of time.

"You can see the integrated circuit board tomorrow morning, but there is no mold ...... the package," Hou said.

The packaging process is also necessary, just the circuit board, which cannot be used at all.

Dust or something can easily damage this circuit.

"There is no need to worry about packaging for the time being, as long as we make sure that the chip we produce is comparable to the performance of the 68000. Xie Kai said.

"Good. Hou Weigui nodded, and did not leave, but looked at Xie Kai and Zheng Yucheng with some embarrassment, looking like he wanted to speak and stopped.

"Say whatever you want. Zheng Yucheng looked at Hou Weigui, "We are not unreasonable people. ”

"The main use of this chip is to use in game consoles and export to the international market, and if it is known by the people at Motorola, it will be devastating to the entire industry. Their chips are all patented. "Hou Weigui has inspected the market in the United States and understands the market.

China has never cared about patents.

Especially in the military-industrial system, there is no such thing as a patent at all.

After all, if you want to apply for a patent, you have to disclose the technical characteristics to the patent office of the country where you apply for it.

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

"Isn't this their blueprint?" Hou Weigui puzzled. "When the time comes, ...... start a lawsuit"

"Just rest assured. Xie Kai said.

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

"There is an embargo on us, that's because we don't. Once we have it, this kind of thing naturally has no embargo value. Xie Kai said with a smile, "When the time comes, we can find foreign packaging factories to package!"

Xie Kaibi knows to everyone that they have got other people's scrapped production lines, and if they are modified to the extent that they can be used, it does not mean that they can make a breakthrough in China.

"It's the same as the CNC system? We have it, they don't have to limit it?" Zheng Yucheng understood a little, and some didn't.

"We have it, and they continue to blockade it, forcing us to make progress faster......" There is some truth that Xie Kai can't tell Zheng Yucheng.

Anyway, as long as foreign countries don't block the country, they can get a lot of them, and there will be no problem.

High-end chips are too much needed in China.

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

"Tested and how is the performance?" Xie Kai asked.

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

"Of course not! Many big names have improved the circuit and optimized the design! The number of transistors is not so many!" Xie Kai said proudly, but there was no reaction on the surface, and said, "Whatever, just use it." How much can you provide in a month under the current conditions?"

"If both lithography machines and other equipment can be used, we have a sufficient supply of silicon wafers, and we can produce 20,000 of these chips per month. ”

"Under existing conditions. Xie Kai just wanted to know how much he could produce now.

The demand for high-performance chips at the 404 base is simply too great.

The domestic demand is even greater than that of 404, and there is no shortage of this thing in the fields of mechanical automation and industrial control.
