Refurbishment: Turning Waste into Treasure

"Hopefully! 35

Xu Fan looked at the OLED screen production line on the side, a little complicated: "I hope the yield rate is okay, otherwise I really can't make it!

As far as he knows!

The deposition system vapor deposition machine is below 5 microns, and its yield is between 80% and 85%!

According to this data as a reference, the error of 8 microns will probably be lower than the 70% yield rate. As for whether it will be pulled below 60%, he is not very clear!

Generally, a yield rate lower than 60% has no value, that is, it cannot be commercialized. It is because the yield rate is too low, which invisibly increases a lot of costs in the production process. Originally a 6-inch OLED Screen, the cost is about 600 yuan!

Then under the yield rate of less than 60%, the cost of an OLED screen of the same size will become about 800 yuan. In this case, how can you commercialize it?

need to know!

The price of a mobile phone is there, even if it is a high-end 24-end model, it cannot be higher than a certain high price, otherwise it will not be able to sell, and a mobile phone is not only the cost of the screen, but also the CPU , memory chips, baseband screens, batteries, motherboards and more!

If the cost of an OLED screen exceeds 600 yuan, it is practically impossible to install it on a mobile phone, and then it will be sold!

The best is the cost of the screen. If the new high-end OLED screen is compressed under the cost of 550 yuan, then there is not much problem. If you want to reduce the cost to about 550 yuan, then the yield rate should be at least 60%. five or more.

The yield rate is too low. He really has no way to go to Weihua Company to sell it. In his heart, Weihua Company has always been a respectable company. From the previous lithography machine to the current OLED screen production line, You want to sell it to others, why don't you plan to support it?

Three hours!

Neither sooner nor too late.

"Boss, a comprehensive evaluation has been carried out. There are no problems with other aspects of the production line, and they are all good!"

Yi Xue came over in person, after all, he was appointed as the director of the entire R&D team and the leader, and he showed his importance by coming in person: "As for the deposition system evaporation machine, combined with the entire production line, the yield rate is 7%. Eighteen or so!

"Seventy-eight percent?"

Xu Fan couldn't believe it, but he asked one more question: "Are you sure? There is such a high yield rate?

"Naturally impossible!

Yi Xue gave such a maddening answer, but did not make people wait too long, and said the following: "Because of the production process and some technical reasons, in the initial stage, there can be 3% The yield rate of ten is already very good!"

"Accumulate enough experience in continuous manufacturing, and then there is the running-in of the entire production line, and the technology of OLED screens, if you understand a little more, the yield rate will continue to rise, unless they don't want to improve! 35

"This is a process, the process is long or short, and ultimately it depends on the company itself, but its limit is indeed a 78% yield rate. If it is optimal, it can reach this level, and then go up. There is no other way, the deposition system evaporation machine is still within the scope of the laboratory engineering team! 35

Yi Xue explained it, and finally did not forget to emphasize: "The OLED screen production line is like this. In fact, the initial stage of the LCD screen production line is also the same. All emerging technologies require a process."

"Well, rigorous! 35

Xu Fan now understands it completely. It's a superficial truth. If he thinks about it himself, he can understand it, but he can't understand it so deeply: "As expected, it's only for R&D, okay...you have someone paint it. Drop it, this device is a Sanwu product. Anyway, there are some small parts that are labeled and cleaned up, so don't let people see it as tricky.

"Boss...except for the paint on the outside, there are no labels!

Yi Xue still has the same attitude as a scientific and technological worker, and is still very strict: "It was originally an engineering machine in their laboratory. It is an experimental equipment. The shell has a coating, which is already the limit."

"Okay, it's easier now!"

Xu Fan was stunned, then smiled: "Print out the evaluation report, then give me a copy, I will take it with me! 35

"OK!""

Xu Fan didn't speak anymore, he took out his phone and made a call, checked the time, it was already 6:30 pm, neither too early nor too late, there was no problem at all, and he was able to grab a work meal from Weihua Company. .

I got in touch with Mr. Ren directly, but there was no contact on the phone. In the end, I had no choice but to call Yu Dazui, which was quickly connected, indicating that I wanted to visit, and by the way, have a working lunch!

Yu Dazui was also refreshing, and he joked on the phone that he would immediately ask the chef of the restaurant to open a small stove, and there would be at least four dishes and one soup to eat when he arrived.

hang up the phone!

Bring the evaluation report and drive directly towards the Weihua company base!

Warehouse No. 1 is a lot closer. If you start from Huashen North, you can't get there in an hour, but from here, it only takes about half an hour to arrive. If you are in the same straight line On, then it is estimated that it will only take about ten minutes.

Chairman of Bluestar Second-hand Trading Group!

Just because of this identity, no one dares to underestimate it now, especially on the side of Weihua Company, the name Xu Fan is not light, but also very heavy. It is really only a lithography machine. Bringing huge benefits to Huawei.

This is not!

Yu Dazui deliberately put down the work at hand and waited at the gate of the company base, without even bringing his own secretary assistant, 090 just waited!

"Mr. Yu... You are a little out of specification! 35 Xu Fan is half-joking and half-serious!

"It should be, it should be!

Yu Dazui laughed, knowing that Xu Fan, a young man likes to joke, although the two only met once, but they were already familiar with each other. Let's go directly to the cafeteria. I received your call just now. I didn't eat dinner. I borrowed your light to eat the chef's small stove.

"So, you're going to be my meal?

"Don't say it...that's what happened!"

"Don't don't don't... This is your territory for the Chinese company, and it's also your territory!"

"We are Huawei, especially HiSilicon, but no one treats you as a guest, even if you are a guest, you are the most important kind of guest!"

Yu Dazui became very serious, showing that he was not joking: "If it's not serious, if it weren't for you, it would be the same thing for HiSilicon. After all, the chip is not just as simple as the design. Design and manufacture?

"Looking for a OEM, hehe... Once something changes, it's all useless! 35

If Yu Dazui points to something!

This is enough to show that the people of Huawei, from Mr. Ren to the entire management, to the R&D personnel below, I am afraid they have a full prediction of the future situation!
