Compared with the various problems faced by Fang Huanzhi and Nanyuan Electronics Factory, the situation of Zhengnan and Jiangxia Electronics Factory is slightly better.

Of course, it's just a little better, it's not that there is something wrong with Jiangxia Electronics Factory, but that Zheng Nan has higher requirements.

Do the best!

Zheng Nan has this idea, Zheng Nan knows very well that now the world's chip manufacturing process has already entered the nano era, if the clean room is according to the standard of the radio factory, I am afraid that it will soon be insufficient, so they must implement it according to the highest standards when decorating.

The idea is great, but it's not so easy to put it into practice.

Because the working principle of the clean room is to blow the air through the fan, and blow all the dirty things in the clean room out by continuously blowing in clean and dust-free air.

Li Xing told Zheng Nan that the general clean room standards are now around level 5 to level 6, which is probably similar to that in the operating room, and the clean room of the radio factory is almost this level, which is also the level originally designed for this pseudo-clean room.

"According to the original design, as long as this pseudo clean room is installed with a fan on the ceiling and then buried in the air duct around it, it can become a de facto chip production clean room, because the actual process of the 65 lithography machine is in the micron range, and the requirements for the clean room are not so high."

The lithography machine is Li Xing's dream, so although Li Xing is not engaged in civil engineering, the design and construction requirements for clean rooms are still at hand.

"But if you want to raise the cleanliness level again, it is not easy, not only the current design of the blowing system can not take away all the dust particles, the floor and ceiling must be worn and redone, and now the high-efficiency filter we ordered is not up to standard, we must order ultra-high-efficiency filters from abroad, which is ......"

Li Xing looked at Zheng Nan and stopped talking, but even if he didn't say it, Zheng Nan understood what he wanted to say, it was nothing more than that there was no foreign ordering channel and no foreign exchange in his hand.

Although this can still follow the path of Douglas, first, Douglas's profiteers set the price up, and secondly, the filter is a consumable that needs to be replaced regularly.

All in all, there is basically no way to do it.

Of course, Zheng Nan also understands these: "But the problem is that now that foreign processes have already entered the nano era, we can't stay on 65 lithography machines and VCD chips forever, is there any other solution to replace them?" ”

Li Xing thought for a moment and gave the answer: "Maybe we can try repeated filtering." ”

To put it simply, it is to increase the filter, let the air filter repeatedly, and achieve a better filtration effect by increasing the number of filtration times.

"But it would have required more piping designs and four to five times more filters." Li Xing replied.

Zheng Nan waved his hand: "It's all a trivial matter, whether it's a pipe or a filter, these are all domestically produced, and you can buy them with money." ”

After some discussion, it was decided to iterate the filtration to a higher level of cleanroom standards, but at the same time to leave a margin for the pipes and filter windows to ensure that the ultra-high efficiency filters could be easily replaced when they were able to purchase them.

In this way, the floor and ceiling can maintain the current situation, and there is no need to wear through and rebuild, or it will be really worn and rebuilt, not to mention whether it can be done in a month or half a year, and it can only be done as best as possible under the existing conditions.

After finalizing the plan, Li Xing came forward to find the construction unit and contact the fan air conditioner installation.

Yes, air conditioning is also very important in a clean room, because whether it is a lithography machine or a chip, it is a very precise thing at the micron level, and any bit of temperature causes heat. Expansion and contraction may lead to the failure of the entire production.

These are all connected when the pseudo-clean room was renovated last time, and now they are all familiar with the road, and even after reviewing the factory's finances, Zheng Nan also expanded and renovated a pseudo-clean room next door.

This is because Zheng Nan doesn't know how long Nanyuan Electronics Factory will rent a clean room, and if he wants to continue to develop lithography machines, he also needs a clean room, even if it's just a pseudo clean room.

At the same time, this is also for the future when the original clean room is not enough, it can also be used as a backup workshop roof.

In addition to the decoration of the clean room, Zheng Nan also expanded the Jiangxia Electronics Factory, mainly about the security department.

The reason is very simple, the Nanyuan Electronics Factory is now a huge thunder, and now it can still be safe in the radio factory, that is because even if the radio factory is not as good as before, but at least the size of 3,000 workers, as well as the prestige of the factory director Chen Zhouyi in the past, no matter who wants to make trouble, they have to weigh it first.

But once Fang Huanzhi and them finish their studies, they will not be able to come to Jiangxia Electronics Factory, maybe now they can argue with Chen Zhouyi, but that is only in the electronics industry, who knows so much from outsiders.

Everyone can only see that your Jiangxia Electronics Factory is a small factory with hundreds of people, or the kind that was about to go bankrupt a few months ago, and the factory director is still a halfway monk.

Therefore, in the foreseeable future, once Fang Huanzhi leads people to enter the clean room to produce chips, he will inevitably face a wave of impact.

Zheng Nan also hoped that he was thinking too much, but he couldn't stop thinking about it.

Zheng Nan finally took care of his good brother Li Lei.

"After this period of study, I studied with Accountant Shen and signed up for classes, but I think I may not be this material, Xiaonan, you have no problem letting me keep accounts and manage the accounts, but if I want to be in charge of finance, I'm afraid I may not be competent." Li Lei said.

This was expected by Zheng Nan, after all, they were originally from a school, if Li Lei had such a talent, Zheng Nan would not know?

Zheng Nan patted him on the shoulder: "It doesn't matter, I'm not making you an accounting master, I just let you understand the accounts, just understand and sort out the accounts, because when the factory grows bigger, I must have a completely trustworthy person to manage this stall." ”

It is true that Shen Shaobo has no problem now, that is because Jiangxia Electronics Factory was small in the past, and he saw less money, plus there is also an old factory director who also understands the account, so there has been no problem, but when Jiangxia Electronics Factory develops in the future, especially when it really makes lithography machines and reaches a scale of hundreds of millions?

However, Zheng Nan doesn't trust Shen Shaobo, but such an important thing can't be all pressed on the morality of a stranger, it is simply gambling.

As for Li Lei's ability, Zheng Nan is not worried, because Zheng Nan never asked Li Lei to be a calculating accountant, but asked him to audit, and being able to understand the accounts and sort out the accounts is the key.

Bookkeeping, accounting, and financial calculations, now that the factory is small, it is enough to have Shen Shaobo alone.

When the factory grows in the future, I will definitely recruit more accountants, and even if it is a surprise audit, I can entrust it to a special audit company.

In short, the most basic thing is not his turn at all, Li Lei, he only needs to have the ability to help himself.
