People from the Imperial Capital did not know that department faxed Zhou Qingfeng a few pages of the list of requirements. The person who wrote this list was really unusual.
At first glance, the models and names of many tools and components are listed, but the listing is also very skillful, which fully tests Zhou Qingfeng's supply capacity.
For example, machine tool tools, high-speed steel is relatively common, and cemented carbide is on the top level. Cubic boron nitride tools are very expensive and not easy to buy.
As for ceramic knives, they are at the forefront of today's material science exploration.
The latter electronic devices are more particular, one item is more high-end.
High-power SCRs are widely used in the industrial field, as well as in the military field. If Zhou Qingfeng can get it, it means he has some strength.
But the MOS devices of gallium arsenide and gallium nitride are biased towards military use.
For example, the radar of a fighter aircraft needs to launch as much power as possible in the smallest possible space, and satellites are pursuing extreme performance under extreme weight, and these things are needed.
China is still in its infancy in these two fields, while the United States has already begun to use them.
The famous "Aegis" air defense system, its radar uses gallium arsenide devices. Its later improved model even used gallium nitride.
Gallium nitride is still in a 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 the core components of guided weapons, and they 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, as well as work normally under strong electromagnetic interference.
If it is an aerospace chip, the computing performance does not need to be strong, but in addition to more stringent environmental adaptation requirements than military chips, it also has to withstand the strong radiation of cosmic rays.
This makes such chips very difficult to deal with.
For example, the AT697F processor dedicated to satellites by Atmel of the United States. This is a product more than 20 years later and can be exported. But the price of a chip is as high as seventy... million U.S. dollars.
In addition, there are some that are not exported, and even the models are kept secret.
The output of cutting-edge military chips is very low, with only a few hundred to thousands of masks at a time. Every time there is production, there is a special person guarded by the military.
When the production is over, all mask materials, chips and even waste products will be taken away. What I'm afraid of is that someone will sell it secretly.
If Zhou Qingfeng can really get high-end gadgets, he will have a lot of weight in the minds of the imperial capital ministries.
Open the window of the e-commerce plane, industrial garbage column, machine tool category.
Different types of tools have their own applicable environments and cannot be substituted for each other. But if you really want to talk about the direction of high technology, then cemented carbide tools with cubic boron nitride coating are the first choice.
The hardness of boron nitride is second only to diamond, but its thermal stability is far superior to 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 has led to the stagnation of related research.
It was not until the 1970s that aero engines began to use iron-based superalloys, and ordinary tools could not process this stuff at all. This is the domestic country eagerly thinking about engaging in cubic boron nitride.
By the 1980s, the situation was even worse. Automobile manufacturing, aerospace, and electronic technology all require high-performance cutting tools, and the country can only find ways to import them.
A knife costs hundreds of thousands of dollars, and the expensive one makes people want to cry.
In the 1990s, new materials and new processes emerged endlessly. Forcing the rabbit to promote the progress of the production process of cubic boron nitride through "external technical exchanges".
But even 30 years later, the domestic tool industry has not reached the peak, and it is still at the bottom of the industry chain. The quality of finished knives is not high, and they still rely on imports.
Zhou Qingfeng's fingers smashed, and two tons of used knives smashed on the handmade carpet in the living room of his mansion. Expensive Persian carpets are not decently ravaged.
The alchemy workshop opened, a dozen soul slaves floated out as coolies, and scattered and used boron nitride knives were moved into the alchemy circle for repair.
This includes a lot of things like drill bits, milling cutters, turning tools, planers, and so on. It took half a day just to carry it.
With the knife done, Zhou Qingfeng felt that he was coming to get some cutting-edge stuff.
chip.
No foreign top-secret advanced processors can be found on the e-commerce plane. This thing was either launched into the sky or destroyed by supervision.
In fact, foreign military-grade chips are rare. They are either installed in missile shells for use on the battlefield, or destroyed after storage expires.
Most of the things that can be thrown away as garbage are industrial grade.
For example, Zhou Qingfeng saw an AD585, a product of ADI in the United States. This kind of chip has different grades, and its working environment is also different.
Among them, the operating temperature of the S grade is marked as'minus 55 degrees to plus 125 degrees', which is by no means affixed to the circuit board of sex toys for analog-to-digital conversion.
Bought, bought, bought!
Zhou Qingfeng was about to get started when he discovered that the minimum purchase amount was one ton. But AD585S uses 14-pin SMD package, and a chip weighs only a few grams.
I really bought a ton, 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 in spaceborne computers. It is used in the Beidou series. This kind of CPU is a bit too strong at the moment.
You must know that the calculation speed of the 486 is only 50 megabytes, and the Loongson 1E and 1F have reached 200 megabytes.
Strangely, domestic high-end chips are sold unrestricted on the e-commerce level, but foreign ones cannot.
When it comes to the 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 about to return to the United States. They were arrested by Guoan plainclothes at the Imperial International Airport.
The latter thing can be a spy movie.
After Gao Zhan was arrested, her husband and his 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, demanding'rescue' Gao Zhan.
The US media was in an uproar and collectively supported it.
This incident lasted for several months. Gao Zhan's husband had originally obtained a green card, but he was naturalized in the US FireWire, and the oath ceremony was even held in the Capitol.
A vote of senators and congressmen gave speeches in support of Gao Zhan and demanded that the rabbit government release her immediately.
On April 3 of that year, the U.S. House of Representatives, the Judiciary Committee's Immigration Group, and a senior Democratic congressman, Sheila Jackson Lee, proposed a bill (Proposal Number: HR1358).
The bill proposes to grant Gao Zhan an oath of naturalization, so that the Yingjiang government can claim people from the rabbit government in the name of Gao Zhan being an Yingjiang citizen.
Do you think Yingjiang is shameless now? People have long been shameless.
But this is not over!
On April 5th, the Republican senator from Virginia, George Allen, united with six other senators from the Democratic and Republican parties, proposed a similar bill in the Senate (Proposal Number: S.702).
Both of these bills require the Attorney General of Yingjiang to grant Gao Zhan Yingjiang's citizenship immediately without going through the oath process. To put it bluntly, it means to stir up shit.
By this time, things are too much trouble.
As early as March, when Vice Premier Rabbit visited Yingjiang's home, then President Bush and Secretary of State Powell raised objections to this matter.
But Gao Zhan is still a rabbit citizen.
Is this the end of your business? Pattern!
The next operation is called dazzling.
On July 24, the rabbit prosecutors determined that Gao Zhan was engaged in espionage activities for Taiwan, and the court sentenced her to ten years in prison.
On July 25, the spokesperson of the State Council of Eagle Sauce stated that he would use every level of diplomacy to put pressure on the Rabbit Emperor and urge Rabbit to release Gao Zhan on humanitarian grounds.
On July 26, the White House spokesperson said that President Bush had spoken with Rabbit III to discuss the Gaozhan incident for the first time since he took office.
On the same day, Yingjiang Secretary of State Powell paid a state visit to the imperial capital and put pressure on the rabbits on this issue.
Everyone felt that the rabbit would definitely not give in. But the next thing is called a turnaround.
On the 26th, Gao Zhan, who had just been sentenced, was allowed to go on parole for medical treatment. She quickly fled to Yingjiang's house and was welcomed like a hero. She also delivered a famous speech at the airport.
President Bush was proud of this, feeling that his own pressure had played a role. The Eagle Sauce media even hailed this as a victory of'freedom and democracy'.
But...
In 2003, Gao Zhan was arrested again on charges of espionage. But this time it was the Eagle Sauce FBI who arrested her.
The Virginia court accused Gao Zhan of selling banned high-tech products to Rabbit’s CLP 14 since 1998.
Including dozens of military-grade 486 chips.
Gao Zhan and her husband were imprisoned.
This matter was vigorous but anticlimactic, and Ying Jiang was so embarrassed that it was not even mentioned later.
But the rabbit lost a "deep sea", no matter how you look at it, it is a big loss.
From this we can see how important cutting-edge chips are.
But now, Zhou Qingfeng has many military-grade 486 chips in his hands, and even more advanced ones.
But...
No, no, it's only 1991.
You can't get too high-end, just change to a low-end one, just so-so.
