It should be repeated that before Hu Wenhai was reborn, he worked as a chief engineer of the semiconductor factory in Ningbo byd.

Ahem, as a former employee, Hu Wenhai actually admires Boatman Wang. To be honest, Boatman Wang should be somewhat similar to Ren Zhengfei of Huawei. Both of them are the best in private enterprises and are also a bit silent in China. However, in their respective fields, they always pursue technological progress.

Let’s talk about Byd’s Ningbo Semiconductor Factory, it turned out to be just a mess that no one took over by Ningbo Zhongwei. It started using TSMC’s level in the 1980s and later eliminated a batch of 15-micron second-hand production lines that transferred backward production capacity. By 2008, byddy acquired the factory, this production line had been operating in Ningbo for at least ten years, but the yield rate was only 40%.

The benefits it creates can be said to be wasted by the discounts given by Ningbo and the high expectations it has placed on it.

It was under such pressure that Boatman Wang spent a huge amount of money to take over this mess. The first thing he did was to increase the processing accuracy to the sub-micron level of 08 based on the 15 micron process.

In the following years, Boatman Wang invested more than one year. His investment in fab technology upgrading was even ten times higher than the original acquisition price!

Finally, I can be very proud to say that the key igbt power driver chip on the latest electric vehicle "Qin" released by byd is produced by Byd's Ningbo factory! Only Infineon can master this technology internationally, byd is also the first Chinese company to master this technology! To this end, byd has established byd's leading position in the field of domestic electric vehicles!

Ahem, I’m very embarrassed to say that in the process of achieving this achievement, Hu Wenhai made more or less contributions. Especially in the process of upgrading the 15 micron 08 micron process, he participated in the improvement of the wafer production line throughout.

From lithography machines to etching machines to meteorological precipitation CVD, from front-end processes to film plate making, from circuit design to production arrangements, the yield rate, which was originally less than 40%, is increased to more than 95%.

Hu Wenhaike experienced all the technical routes from scratch, and all the designs and parameters were in his head. In order to firmly sit down, he even studied as a graduate student in Optical Engineering at Huake.

Question, what is the most important equipment on the chip production line? The answer is definitely the same, that is, the lithography machine. Question, what is the lithography machine? Simply put, it is the equipment that uses laser to pass through the mask plate to engrave circuits on the chip.

So, it can be imagined that Hu Wenhai has some research on the more or less of a laser—moderate statement. As for military lasers, as a puppet military fan, have you never eaten pork or seen pigs running? For example—

Yttrium aluminum garnet crystals can emit lasers of 106 micron wavelength after being irradiated by high-energy flashlights and concentrators. Don’t underestimate this short line of data. Just these forty words will be put into the world in the 1970s, and it will be no problem to sell them for tens of millions of dollars.

Because this is a laser that is currently found by humans and is relatively most suitable for propagation in the atmosphere. Its atmospheric propagation performance is slightly worse than carbon dioxide lasers, but because it is a solid laser, it can be very small, which is obviously a more important factor for the application volume in war.

The solid giant pulse laser excitation using yttrium aluminum garnet was experimented little by little in countless possible laser excitation solutions. Even in the early 1980s, only the United States, Britain and France were the only ones who mastered this set of data.

The newly established optoelectronics laboratory of Xinke Company still has some basic foundations, such as the power circuit device used to drive LD chips. Hu Wenhai took the time to draw a picture in the afternoon and asked Bai Shi to install the components on the spot.

For falsehood, we can even make igbt, let alone the power driving circuit used to drive ld chips. The so-called ld, one letter different from LED, is not much different in actual meaning. ld is the abbreviation of semiconductor lasers (La color Rdiode). Like LED, it can realize photoelectric conversion. In simple terms, the light generated by LED is divergent, while the directionality of ld light emission is much better.

High-power LD chips use concentrators to excite yttrium aluminum garnet crystals. This is the core technical basis of laser target indicators in modern laser guidance methods.

The next thing to do is to encode the laser through the electro-optical q-gate gate. This is a device similar to blinking, which can make the laser flash at different frequencies every second. Laser-guided weapons cannot see a beam of light and give it to a kiss, and they must recognize their own frequency.

Then, the laser is refracted with various prisms, and finally through the filter and the front-section telescope, a modulated laser that can indicate the target is made.

Yes, it seems that the high-tech laser guidance target indicator is actually so simple. And in fact, laser guidance has entered thousands of households in ordinary people in the future. Think about it, sometimes the infrared remote control at home can still be remotely controlled to change the TV station even if the direction is opposite, that is, the TV receives scattered signals illuminated by infrared light on the surface of the object.

The US military's famous "Gem Road" laser guidance system is essentially no different from these things.

Let me give you another word: Many offices have automatic fire alarm fire extinguishing probes, which is a degraded version of infrared guide.

The technological progress caused by the threat of war has long been benefiting the entire society without realizing it!

But then again, as the most used guided weapon system in the US military, it is not cheap and even the Pentagon cannot afford it if it is not simple.

Hu Wenhai purchased commercial semi-finished products in the United States this time, which avoids the trouble of starting from scratch. With mature design ideas and specific weapon data, the difference is like starting to solder a computer from a capacitor, which is the difference between buying a CPU, memory, motherboard, hard disk, and assembling a computer.

The latter is naturally countless times easier, but combining a computer with the most cost-effectiveness also requires countless people to contribute their wisdom.

Hu Wenhai simply saved this step and could directly take out the list of the most popular installations of Computer Home.

"Yes, here the condenser is set in front of the LD chip, and all the light is concentrated on the yttrium aluminum garnet laser rod." Hu Wenhai arranged the equipment he got on the table and explained their specific functions and uses to Bai Shi one by one. Then he used an oily pen to draw the working drawing of the entire laser target indicator on the whiteboard hanging on the laboratory wall.

"Then the laser is then directed into the Puker electro-optical q-gate box through the prism, and finally entered the laser output prism through the polarizer. Do you understand?"

Bai Shi held the thick-framed glasses on his nose, carefully compared the actual objects on the table with the functions of each part on the schematic diagram, and asked questions that he couldn't understand while looking.

It was just like this that he had asked and answered it. After spending an afternoon, Shiraishi almost recorded the contents of the entire notes, and then hesitated that he had already understood all the key points of the entire design.

"But Mr. Hu, if you use it to the battlefield, should you pay attention to shockproof, waterproof, dustproof and other measures in the design?" Shiraishi has not done military projects, and he still has his own ideas.

Hu Wenhai waved his hand and said generously: "No rush, your task is to develop this system first. As for the final weapon structure design, we don't have to worry about it."

This is why the two people look at the problem differently. Hu Wenhai didn't expect to send this semi-finished guidance system that is not produced energy to the battlefield so soon.

Heng Jianyun's company is still on the Annan front line. It is impossible for him to come back to change clothes, nor can he accept the equipment made by Hu Wenhai for no reason. At this time, he saw the benefits of wearing a layer of military unit skin of the 501 Factory. As long as the weapons and equipment are produced, the militia company of the 501 Factory can be equipped with the 501 Factory in minutes.

The 501 Factory, which originally had more than 3,000 people, had a militia battalion. Now, two-thirds of the militia have left, and only one company is left.

But it doesn't matter. When the equipment is developed, the militia company has formed combat effectiveness. The relationship left by Heng Jianyun can be contacted by senior leaders of Shengjing Military Region to give Hu Wenhai a chance to perform.

Ahem, then again, even without Heng Jianyun's relationship, Hu Wenhai can still meet the leaders of Shengjing Military Region at any time. Who wouldn't be jealous of the twenty F-14s?

In other words, the first batch of laser guidance weapons were probably thrown on the test site. Since that is the case, there is no need to rush to use any shock, waterproof, and dustproof measures.

When the interest of Pla is attracted, then there will naturally be professionals in the weapon system design, and Hu Wenhai has no intention of choking with the military system.

Xinke Company can supply bulk parts by then, and other military factories can provide assembly and commissioning. If you have money, you can make money together. This is much safer in the military system than eating alone.

We come to make money, and we will naturally receive the face of earning meritorious and rewarded by the unit in the system. Both sides are happy, and Hu Wenhai is happy to make a fortune in silence.

Just as he explained his entire idea to Bai Shi, Hu Wenhai raised his hand and looked at his watch, it was almost five o'clock.

Thinking of the poor Yu Shiwei being left in the factory for an afternoon, Hu Wenhai quickly packed up his things and left the small building of the technical department.
Chapter completed!
