The nut that never loosens, the principle of this nut, the island country's Hadlock has announced it on his official website, and people are not afraid of you imitating it at all.

This nut that never comes loose consists of a set of two concave and convex nuts.

The nut with a convex shape below is slightly staggered in the center axis during processing and manufacturing, and plays the role of a wedge.

The nut with a concave upper part is not processed off the central axis, so the locking function of the hammer wedge is formed.

When two nuts are combined into one, the problem of loosening is solved.

Because the contact surface of the two nuts has very high precision requirements, there should be no way to manufacture this kind of anti-loosening nut in China

This is also an important reason why the Hardlock Company has unabashedly published its manufacturing principles.

The reason seems simple, but such a nut is not so easy to copy.

Because the extremely fine product data is the result of decades of research accumulated by others little by little, it is difficult for others to copy it for a while.

"Xiao Dai, the current subprime mortgage crisis has begun to affect the island countries, right? I read the news released by Nomura Securities last week, the economy of the island countries has also begun to be impacted, is it possible that we will also acquire a number of small and micro enterprises in the island countries this year?" Jiang Hui suddenly looked at the technology of these enterprises.

Hadlock is just one of the countless small and micro enterprises in the island country, and there are thousands of parts on mobile phones and cars, many of which should be able to find some unique technology among the small and micro enterprises in the island country.

"It's not impossible, but the risk is relatively large, these small and micro enterprises are workshop-style family businesses, and the technology is in the hands of a few people, if you just buy other people's companies, and the employees are gone, those equipment or something alone are not worth anything at all." The more he understands the island country, the more Dai Fuqian feels how closed the island country's enterprises are.

The smaller the business, the more conservative and closed it is.

If Jiang Hui were to acquire several medium-sized and large-sized enterprises in several island countries that had already embarked on internationalization during the financial crisis, it would not necessarily be very difficult.

But when you go to buy small and micro enterprises, this foreigner really doesn't have to try it easily.

The Americans have been the emperor of the island country for decades and have not solved this problem, Jiang Hui wants to do it easily, where is it so easy.

"Let's keep an eye on it first, whether it will work out or not is another story. Let's go back to the development of electronic components," Jiang Hui said.

"Okay, I'll start with the chips, motherboards and storage you just mentioned, Mr. Jiang," Zhu Zhengfeng interjected.

As the vice president in charge of R&D of Guanghui Mobile Phone, Zhu Zhengfeng undoubtedly has a deeper understanding of the various parts of the mobile phone.

"The so-called chip, in fact, is an integrated circuit, a kind of miniature electronic device or component. Using a certain process, the transistors, resistors, capacitors and inductors and other components and wiring required in a circuit are interconnected together, and are made on a small piece or several small pieces of semiconductor wafer or dielectric substrate, and then encapsulated in a tube shell to become a miniature structure with the required circuit function; all the components have formed a whole in the structure, so that the electronic components have taken a big step towards micro-miniaturization, low power consumption, intelligence and high reliability. ”

"Integrated circuit technology includes chip manufacturing technology and design technology, which is mainly reflected in the ability of processing equipment, processing technology, packaging and testing, mass production and design innovation. ”

"Mr. Jiang, you must have heard of Moore's Law", Zhu Zhengfeng looked at Jiang Hui and said.

"Of course, you continue," Jiang Hui said, glancing at Zhu Zhengfeng.

"When the price is the same, the number of components that can fit on an integrated circuit doubles about every 18-24 months, and the performance doubles.

For a while, people said that Moore's Law was invalid, and Intel couldn't do it on its own, and some people said that the IC industry was actually developing faster than Moore's Law.

In any case, semiconductor companies around the world have been investing heavily in new process processes, which are marked by the line width of integrated semiconductor components.

Every progress in the manufacturing process brings smaller line width, smaller power consumption, higher operating frequency, more components can be integrated, and stronger performance is achieved. ”

"The most advanced processes in the semiconductor industry range from tens of microns to a few microns to hundreds of nanometers. 130 nm, 65 nm, 45 nm, it is said that Intel has developed 28 nm technology, the future 20 nm, 16 nm, 14 nm, 10 nm......

Every two or three years, a new generation is introduced, but based on these line widths, each manufacturer still has different process technologies.

Sometimes the line width is just a commercial publicity stunt, because each transistor on the IC circuit is built from a variety of semiconductor materials, and the shape and line width of each material may be different.

For example, there are many discussions on the Internet that Intel's 60nm process technology is stronger than TSMC's 45nm process technology in terms of actual effect. Therefore, when evaluating whether the process technology of an IC factory is advanced, line width is an important reference, but it is not the only one. ”

Although Jiang Hui was a little dizzy when he heard Zhu Zhengfeng say about these professional knowledge, he was still listening very seriously, this is likely to be related to the future investment of tens of billions or even hundreds of billions of Guanghui Group, and it is not okay if he is not serious.

"Speaking of chips, there is another thing that has to be mentioned, and that is wafers.

The wafer is a cylindrical monocrystalline silicon cut into a round silicon sheet, and all ICs are processed on the wafer, and then cut, packaged, and tested, which is the finished chip.

Obviously, the larger the wafer, the more ICs can be made on the wafer, and the lower the cost.

Therefore, in the recent decades of the development of the semiconductor industry, the size of wafers has continued to increase, from 1 inch, 2 inch, 3 inch, to the current mainstream 6 inch, and there will be larger wafers in the future.

In principle, there is no correlation between the number of nanometer wire widths used in the process technology and the size of the wafer, and 2-inch wafers can also be used for 45 nanometers, but in fact, IC factories usually use the largest wafers of that era to reduce costs. ”

Zhu Zhengfeng continued to talk about his chip-related knowledge.

"How much investment is needed for these chip factories with different processes?", Jiang Hui asked a question that he is very concerned about as a boss.

"It's a really critical question. Moore's Law only tells us how the IC process is progressing, but it doesn't tell us how the investment in building an IC factory increases.

From tens of millions of dollars in the 70s, to hundreds of millions of dollars, billions of dollars, billions of dollars, and recently Samsung, Intel and TSMC have invested in 45 nanometer production plants, the investment has exceeded five billion dollars," Zhu Zhengfeng said.
