The emperor didn't know which department faxed a few pages of demand list to Zhou Qingfeng. The person who wrote this list was really unusual.
At first glance, it just lists the models and names of many tools and components, but the list is also very skillful, which fully tests Zhou Qingfeng's supply ability.
For example, for machine tool cutting tools, high-speed steel is relatively common, while carbide is higher-end. Cubic boron nitride cutting tools are very expensive and not easy to buy.
As for ceramic cutting tools, they are at the forefront of current exploration of materials science.
The electronic devices at the back are even more exquisite, each one is more high-end than the other.
High-power thyristors are widely used in the industrial field, and the same is true in the military field. If Zhou Qingfeng can get it, it shows that he has some strength.
However, gallium arsenide and gallium nitride MOS devices are biased toward military use.
For example, fighter jet radars need to emit as much power as possible in as small a space as possible, and satellites pursue extreme performance under extreme weight, all of which require these things.
China is still in its infancy in these two fields, while the United States has already begun to put them into practice.
The radar of the famous Aegis air defense system uses gallium arsenide devices. Its later improved models even use gallium nitride.
Gallium nitride is still in the laboratory state, and its power density is an order of magnitude higher than that of gallium arsenide.
As for industrial control and high-speed A/D conversion chips, these are core components of guided weapons and are also widely used in the industrial field.
Unlike civilian-grade chips that work at room temperature, military chips have to withstand severe temperature changes and vibrations, and must also work normally under strong electromagnetic interference.
If it is an aerospace-grade chip, the computing performance does not need to be very strong, but in addition to more stringent environmental adaptation requirements than military chips, it must also be able to withstand strong radiation from cosmic rays.
This makes this type of chip very difficult to produce.
For example, the AT697F processor of the American company Atmel is specially used for satellites. This is a product produced more than 20 years ago and can be exported. However, the price of a chip is as high as 700,000 US dollars.
In addition, there are some that are not exported to the outside world, and even the model number is kept secret.
The output of cutting-edge military chips is very low, with only hundreds or thousands of chips being masked at a time. Each production is overseen by dedicated military personnel.
At the end of production, all mask materials, chips and even scrap products will be taken away. The fear is that someone will secretly sell them.
If Zhou Qingfeng can really get high-end gadgets, he will have a lot of weight in the hearts of the imperial capital ministries.
Open the window of the e-commerce plane, the industrial waste column, and the machine tool and tool category.
Different types of cutting tools have their own applicable environments and cannot be substituted for each other. However, if you really want to talk about high-tech, then carbide cutting tools with cubic boron nitride coating are the first choice.
The hardness of boron nitride is second only to diamond, but its thermal stability far exceeds that of diamond, and its cutting performance is extremely good. It is a tool that can be used to process high-performance steel.
Domestic research on cubic boron nitride began in the 1960s, but the basic industry was weak and the product stability was poor. This led to the stagnation of related research.
It was not until the 1970s that aircraft engines began to use iron-based high-temperature alloys, which could not be processed by ordinary tools. Only then in China was eager to develop cubic boron nitride.
By the 1980s, the situation was even worse. Automobile manufacturing, aerospace, and electronic technology all needed high-performance tools, and the country could only find ways to import them.
A knife costs hundreds or thousands of dollars, which is so expensive that it makes you want to cry.
By the 1990s, new materials and new processes were emerging one after another. Rabbit was forced to promote the advancement of cubic boron nitride production processes through 'foreign technical exchanges'.
But even thirty years later, China has not reached the peak of the tool industry and is still at the bottom of the industrial chain. The quality of finished tools is not high and it still relies on imports.
Zhou Qingfeng's fingers smacked, and two tons of used knives crashed onto the handmade carpet in the living room of his mansion. The expensive Persian carpet was ravaged to a state of disgrace.
The alchemy workshop was opened, and a dozen spirit slaves floated out to work as coolies, moving scattered used boron nitride knives into the alchemy circle for repair.
This included a large number of drill bits, milling cutters, turning tools, planers and the like, which was a mess. It took half a day just to transport them.
With the knives done, Zhou Qingfeng decided to get some cutting-edge gadgets.
chip.
There is no foreign top-secret cutting-edge processor in the e-commerce space. This thing was either launched into the sky or destroyed by supervision.
In fact, there are very few foreign military-grade chips. They are either installed in missile shells and used on the battlefield, or they are destroyed after storage expires.
Most of the ones that can be thrown away as garbage are industrial grade.
For example, Zhou Qingfeng saw an AD585, a product of American Analog Devices. This chip has different levels and its working environment is also different.
The S-class usage documentation states that the operating temperature is ‘minus fifty-five degrees to plus one hundred and twenty-five degrees’, which is definitely not posted on the circuit board of a sex toy for analog-to-digital conversion.
Bought, bought, bought!
When Zhou Qingfeng was about to take action, he discovered that the minimum purchase quantity was one ton. However, the AD585S uses a fourteen-pin SMD package, and one chip only weighs a few grams.
If you really buy a ton, it will be enough to bury him.
Buy something else.
Loongson 1E and Loongson 1F?
Eh..., these two chips are interesting!
This is a standard aerospace-grade general-purpose processor, used for space-borne computers. It is used in the Beidou series. This kind of CPU is a bit too powerful at present.
You must know that the computing speed of 486 is only 50 MB, while Loongson 1E and 1F reach 200 MB.
Strangely, domestic high-end chips can be sold without restrictions on e-commerce, but foreign ones cannot.
Speaking of military-grade 486, a story must be told.
In 2001, Gao Zhan, a Chinese female scholar with a green card in the United States, and her family of three were arrested by plainclothes national security officers at the Imperial Capital International Airport as they prepared to return to the United States.
What happened next could make a spy movie.
After Gao Zhan was arrested, her husband and son were quickly released. After returning to the United States, the father and son actively lobbied human rights organizations, the media, and members of Congress to "rescue" Gao Zhan.
The American media was in an uproar and expressed collective solidarity.
This matter has been going on for several months. Gao Zhan's husband originally had a green card, but he was naturalized in the United States. The oath-taking ceremony was even held in the Capitol Building.
A group of senators and congressmen gave speeches in support of Gao Zhan and asked the Rabbit government to release her immediately.
On April 3 of that year, the U.S. House of Representatives, the Immigration Subcommittee of the Judiciary Committee, and senior Democratic Representative Sheila Jackson Lee proposed a bill (bill number: H.R.1358).
The bill proposes granting Gao Zhan an oath-free naturalization, so that the Yingjiang government can request people from the Rabbit government in the name of Gao Zhan as a Yingjiang citizen.
Do you think Yingjiang is now shameless? I have been shameless for a long time.
But this is not the end!
On April 5, Virginia Republican Senator George Allen joined six other senators from the Democratic and Republican parties to propose a similar bill in the Senate (bill number: S.702).
Both bills require the Minister of Justice to immediately grant Gao Zhan citizenship without going through the oath process. To put it bluntly, they are just stirring up shit.
By this time, things had become too big.
As early as March, Vice Prime Minister Rabbit visited Yingjiang's house, and then President Bush and Secretary of State Powell raised objections on the matter.
But Gao Zhan is still a rabbit citizen, which is none of your business.
Is this the end of your matter? What a pattern!
The next operation is dazzling.
On July 24, the Rabbit Procuratorate determined that Gao Zhan had engaged in espionage activities for Taiwan, and the court sentenced her to ten years in prison.
On July 25, a spokesman for the State Council stated that it would use every level of diplomacy to put pressure on the Rabbit Capital to urge Rabbit to release Gao Zhan on humanitarian grounds.
On July 26, a White House spokesperson stated that President Bush had a phone call with Rabbit Sandaime for the first time since taking office and discussed the Gao Zhan incident.
On the same day, Secretary of State Powell paid a state visit to the imperial capital and also put pressure on Rabbit on this issue.
Everyone felt that the rabbit would definitely not give in. But what happened next was a twist.
On the 26th, Gao Zhan, who had just been sentenced, was allowed to be released on "medical parole." She quickly fled to Yingjiang's house, received a hero's welcome, and even delivered a famous speech at the airport.
President Bush was very proud of this, feeling that his pressure had worked. The Eagle Media even hailed this as a victory for "freedom and democracy."
But......
In 2003, Gao Zhan was arrested again on espionage charges. But this time it was the FBI that arrested her.
The Virginia court accused Gaozhan of selling high-tech products prohibited from export to Rabbit's CLP 14 since 1998.
These include dozens of military-grade 486 chips.
Gao Zhan and her husband were imprisoned for this.
This incident was vigorous but ended in an anticlimax. Ying Jiang was so embarrassed that he didn't even mention it later.
But Rabbit lost a "Deep Sea", which is a huge loss no matter how you look at it.
From this incident, we can see how important cutting-edge chips are.
But now, Zhou Qingfeng has a lot of military-grade 486 chips in his hands, and even higher-grade ones.
But......
No, no, it’s only 1991.
Chapter completed!
