Chapter 237 235 Siwa Alloy
Since it can be reused, it can save a lot of cost.

The premise is to protect the fine metal mask and maintain it regularly.

At the very beginning, the fine metal masks were also monopolized by the islanders, but we were not reconciled and kept trying to produce them ourselves. The yellow heart paid off, and finally we conquered it.

Now we can also produce fine metal masks, and the quality is not inferior to that produced by the islanders.

Among them, Symphony Moon Company and HNA Outlet Company are the representatives.

It can be said that we have successfully broken the monopoly of the islanders, thanks to these two companies.

You must know that other people are not Zhang Xingchen, but there is no super black technology system, everything is groping in the dark, without any help, completely on your own.

Moreover, the research on fine metal masks is not something that anyone can play, and it will cost money.

We can't compare others with Zhang Xingchen. Xingchen Zhang Xingchen doesn't pay attention to money, and he can get tens of billions with a wave of his hand.

For others, a few hundred million is a large number, and it is a very large number.

Just an assembly line for the manufacture of fine metal masks in the early stage needs 5 million yuan, and the cost of various tests and verifications is also quite a lot, and it will cost about [-] million yuan in a year.

Only those with strong funds can participate in the fine metal mask project. If you have ordinary funds, you should not go into this muddy water.

Really going broke.

From this, we can imagine how much it cost to study the fine metal mask.

If you don't have five billion yuan, it's best not to touch the fine metal mask.

From this we can see that in the process of producing screens, it is difficult for someone or an enterprise to complete the entire process by itself, just like chips.

It requires the cooperation of the whole society and many enterprises.

Therefore, Star Company was able to complete the entire process of the chip to cause such a big sensation. After the insider, how much technology and financial resources were involved in it.

Simply speaking about the company, I am afraid that only the Star Company can do this kind of thing.

After getting rich, the top priority is to recruit talents. You must know that fine metal masks are in great need of talents, and money is not enough without talents.

What kind of talents are needed?Graphic analysis talent!
Under normal circumstances, panel manufacturers will submit a technical requirement to the fine metal mask factory according to their actual situation and requirements, and let them design graphics according to their requirements.

A slightly better one will provide a published fine metal mask design drawing.

But this is just for reference, and it will definitely need to be improved later.

The graphic analysis personnel of the fine metal mask will design and improve according to the customer's requirements, and need to be confirmed by Party A after completion.

As Party B, you have to wait patiently for the result.

In general, it can be said that in most cases, Party B cannot satisfy Party A's requirements with just one submission, and it often needs to be modified several times.

This rule is not only applicable to fine metal mask design, but also in other industries...

There are two types of fine metal masks, one is the split type, and the other is the full type.

This is easier to understand. The full-type is that the entire substrate is covered with a fine metal mask. As for the hollow pattern on the full-type fine metal mask, it is generally etched with a laser.

However, there will be a disadvantage in this way, that is, the efficiency is relatively low, and it is more suitable for use on small substrates.

And if there is a flaw on the top of the full-scale fine metal mask, or it is damaged, then that is to say, the whole fine metal mask can no longer be used and must be repaired, which seems more troublesome.

So what is generally used now is a segmented fine metal mask.

In this case, if the above-mentioned problems occur, it is very convenient to only need to change a small piece.

These two methods are generally used to make hollow patterns on the split fine metal mask, and these two methods are electroplating and etching.

However, among these two methods, etching is the most used method. This method is very mature and is loved by everyone.

During etching, the area that needs to be hollowed out can be continuously thinned by special techniques, and finally the pattern you want is formed. The whole process is naturally very precise, and the obtained pattern is also of high precision.

In the past, when the fine metal mask was monopolized by island countries, it was not only expensive, but also had a long delivery cycle. It was often only one month after we placed the order that we could get the fine metal mask we needed.

Now that we can produce it ourselves, the delivery cycle has been directly shortened by two times, and it can be delivered in about two weeks.

And because the distance is shortened, emergency situations are handled very quickly.

……

As for the fine metal mask, it is produced by Siwa alloy, which is a kind of iron-nickel alloy. Its biggest advantage is that its expansion coefficient is very small, which means that when Siwa alloy is subjected to high temperature, its volume There is almost no change.

The basic principle of thermal expansion and cold contraction has almost lost its function on it.

We must know that almost all materials after our lives are bound by this principle, such as our common water, plastics, and some ordinary metals, which expand with heat and contract with cold.

But Siwa Alloy is not!
The reason for this is that the interior of the Siwa alloy is ferromagnetic, and the ferromagnetism makes the Siwa alloy have a certain abnormal thermal expansion, which makes the Siwa alloy get rid of the control of the law of thermal expansion and cold contraction within a certain temperature range.

This is a very commendable performance. The physicist Dr. Ji Yaomu who discovered Siwa alloy at the beginning won the Nobel Prize in 1923, and it was also the Nobel Prize in Physics!
This is a great affirmation.

Although Zhang Xingchen no longer takes the Nobel Prize seriously, and usually dismisses it even more, it is still a very honorable thing for ordinary people to win the Nobel Prize.

Because Siwa alloy has this characteristic, people often use Siwa alloy to manufacture some very precise instruments, so that the manufactured instruments will not be affected by temperature, and thus will not affect the precision of the equipment.

It can be said that Siwa alloy is one of the essential raw materials for manufacturing precision instruments, so it is called the king of metals!

The shadow of Siwa alloy can be found on almost all equipment that requires very high precision!

The silvan alloys required for the fine metal masks we manufacture are silvan alloys below [-] microns.
