"Lao Zhou, although you are a professor at Huaxia University, the teaching level is also first-class, but don't forget, practice is the best teacher, the things in the books are far less than the knowledge gained from practice, the three of them were high-achieving students back then, and then delayed for a few years, but did not give up, and then came to the third factory, every day they have to work until six or seven o'clock in the evening, studying, Over the years, they have mastered more knowledge than an old man like me, even you, I'm afraid it's not as good as a young man! Hmph, it makes me angry when I talk about it, if this set of equipment had been given to us in the third factory back then, it would have been thoroughly studied now, where would the problem of chips be so troublesome now? It's Su Province, their guys are too delayed, and they are all delayed!"

Xie Xide talked about his three apprentices, and when he talked about the introduction of equipment back then, he was like a thunderbolt, this person is a typical scientist, and he never gives face to others.

"Teacher, you have won the award, we are stupid people, we can only rely on stupid methods, otherwise what else can we do?

Wang Yuan scratched his head and said.

"I don't think you're here to provide for your family......... Let's study hard, the country is now focusing on the electronics industry to start developing, this great opportunity must not be missed!"

Zhou Ming said.

"Professor Xie, have you ever thought of working here?"

Liu Lang asked suddenly.

"What do you mean to work here?"

Xie Xide asked.

"Professor Xie, you have also seen, this set of equipment is the most advanced equipment in our country, it can be said to be a symbol of the pinnacle of the electronics industry, as long as this set of equipment is understood, not to mention catching up with the advanced level of foreign countries, at least it can shorten the distance with them, several are top scientists in China, here is in need of your help, it is better for you all to come here to work, correctly in the shortest possible time to find out all these technologies!"

Liu Lang said everything in his heart.

"Hehe, the little guy is quite able to talk, and he dug up other people's corners, we don't have to talk about this, it's a matter of the organization department, I heard that you are very energetic above, why don't you help us talk to the above, don't say anything else, your food here is much better than our third factory!"

Xie Xide said half-jokingly.

"Okay, I'll try to talk to Minister Du Hongda!"

Liu Lang smiled slightly.

Xie Xide and the others didn't take Liu Lang's words seriously, and soon all their attention was on these parts and integrated circuit boards.

The arrival of Xie Xide and the four of them has increased the speed of their research a lot, the level of these people is indeed very powerful, maybe the theoretical knowledge is not up to the level of Zhou Ming, but the practical level is definitely much higher than Zhou Ming's, each integrated circuit board can say one or two, such as whether it can be done in China at this stage? If it can't be done, how to improve? If they want to reach Wanhe's technical indicators, where to start, and so on.

Of course, everyone's main concern is the manufacture of lithography machines.

"The lithography machine of the island country has been a generation ahead of us, our era is a contact lithography machine, and this one is already a close type, through the air cushion in the mask and the silicon wafer to produce a small gap, the mask and the silicon wafer are no longer in direct contact, its accuracy is twice as high as ours, the biggest difference of this lithography machine is also the improvement of proofreading, we are to improve in this regard!"

A few days later, Xie Xide and Zhou Ming came to such a conclusion.

This conclusion seems simple, but it is not easy to do, they turned on all the lithography machines, you must know that the lithography machine is a precision instrument, its precision far exceeds other equipment, and dust is not allowed to enter it, but there is no sterile laboratory here, in order to minimize the impact, this work can only be carried out in a closed small room, after opening, several people's actions are cautious, one by one shrinking from morning to night, almost tired when they come out, prostration.

But no one said that they were tired, everyone was in high spirits, for fear of missing any detail.

Xie Xide and the four of them stayed in the Jiangnan Radio Factory for nearly a month, there was no day off in this month, everyone worked together, everyone soaked in the workshop every day to continue to study, Zhou Ming and Wang Haijun were the same, sometimes they would quarrel loudly over a certain point of view, so that they would make their faces red, of course, this is all a technical dispute, once they reach an agreed conclusion, everyone will laugh heartily.

Of course, Liu Lang can't miss such a good opportunity, although he is not a student of the electronics industry, but machinery manufacturing is the foundation of all industrial industries, integrated circuit boards also need special machine tools to manufacture, at the same time, there are a lot of metal parts in this set of equipment, some parts are also very high-tech, relying on the current level of domestic manufacturing can not be manufactured, these need Liu Lang to find a way to solve.

In addition, Liu Lang basically mastered some basic knowledge of the electronics industry during this time, and his level may not be lower than Wang Haijun, after all, his brain is almost a computer, and all the data will quickly become his own knowledge after entering his head.

A month later, a lot of key issues have basically been mastered, to the standards of Wanhe company, the imaging accuracy of this set of equipment is not yet reached, if you want to improve again, you need to improve the light source, now this equipment is still to excimer laser produced by the light as the lithography light source, in fact, mercury lamp as the light source, in fact, this method is also used in China, but the relevant technology has not reached the height of the island country's equipment, and in order to improve again on this basis, it is necessary to use more advanced molecular laser technology.

Fortunately, the domestic laser technology is also very "awesome".

"As early as the summer of 1961, under the auspices of laser technology expert Wang Jiang, China's first ruby laser laser was successfully developed, and in just a few years, laser technology developed rapidly, various types of solid, gas, semiconductor and chemical lasers have been successfully developed, in basic research and key technologies, a series of new concepts, new methods and new technologies such as Q mutation and rotating mirror, traveling wave amplification, the use of rhenium ions, free electron oscillation radiation and so on.

In terms of communications, in September 1964, a laser demonstration was used to transmit television images, and in November 1964, a call of 3 to 30 kilometers was realized; in industry, in May 1965, a laser punching machine was successfully used in the production of wire drawing dies; in medicine, animal and clinical experiments were carried out on a laser retinal welder in June 1965; in the military industry, a laser diffuse reflection rangefinder with an accuracy of 10 meters/10 kilometers was successfully developed in December 1965, and a remote-controlled pulsed laser Doppler velocimeter was developed in April 1966. ”

Xie Xide talked about the country's development in the field of lasers in recent years.

"I'm Cao!"

Liu Lang was basically speechless when he heard these words.
