The black technology empire started with a debt of one billion

Chapter 374 Chapter 389: Only 20 yuan

"The cost of this high refresh rate touch screen is only nine percent more expensive than the original." Xu Tianbing replied.

Although Li Yujing doesn't know how much benefit 240hz can bring, he knows that the overall increase of only nine percent is not expensive. Cao Mang is very satisfied with this price. In his previous life, he would have increased the price by at least [-] to [-] percent.

However, I believe that the cost increase in the previous life should be similar to this, and the reason why the price has increased so much is naturally to make profits.

"How much does ultrasonic recognition cost?" Cao Mang asked.

"The cost of this kind of ultrasonic chip is five yuan a piece. This cost is the price of tape-out. The mass production is about 3 yuan and 7 yuan a piece. The price of the chip assembly is about [-] yuan as before." Xu Tianbing Introduced.

The assembly chip is mainly used to process screen data and ultrasonic data.

Because of the need to process ultrasonic data, the chip must not be able to use the public version of the chip, that is, the previous optical fingerprint recognition used the chip customized by Deep Blue.

This kind of chip does not require very high technology, and the 65-nanometer technology is enough.

65nm process chips can be produced by any low-end foundry.

There are many such small foundries in China, and such foundries generally only have three or four lithography machines, and these lithography machines are bought second-hand, because the competition among small foundries is fierce.

So the production cost of this low-end chip is not very high.

Cao Mang calculated the cost of fingerprint recognition in his mind. The four chips cost 14 yuan and 9 cents. The assembly chip must be used, so the cost of this thing does not increase a lot.

In other words, Xu Tianbing realized ultrasonic fingerprint recognition on the touch screen for less than 20 yuan, which is two or three times cheaper than the original optical recognition.

Of course, this is not entirely due to him, Xu Tianbing only accounted for 10% of the credit, and the remaining 90% is all due to the system.

How could they produce such advanced things without the technology provided by the system.

"The cost is too cheap. Qualcomm's ultrasound costs more than 300 yuan, while ours only costs 20 yuan." Li Yujing said in disbelief.

"According to the existing production equipment, how many pieces can be produced every day?" Cao Mang asked again.

"The process of installing ultrasonic chips is relatively complicated. Manual installation can produce up to [-] pieces per day. If you want to increase production, you must automate production." Xu Tianbing replied.

"Xu Tianbing, you have done a good job. Afterwards, you can talk to Lu Mingyu about how to turn the equipment into automatic production." Cao Mang patted Xu Tianbing on the shoulder and said in satisfaction.

"Okay, Mr. Cao." Xu Tianbing nodded.

"How long will it take for Lu Mingyu's production line equipment to be developed?" Cao Mang looked at Lu Mingyu and asked.

At this time, Lu Mingyu was examining the touch screen assembled by the workers.

After hearing Cao Mang's words, he came back to his senses.

"Mr. Cao, I took a look and it's not very complicated. I can get the production line out within a week." Lu Mingyu replied.

"Then I will leave this matter to you," Cao Mang said.

"No problem, Mr. Cao." Lu Mingyu nodded.

"Let's go back first, you two can figure it out." Cao Mang replied.

With that said, Cao Mang and his party left the factory and went straight back to the Deep Blue Technology Industrial Park.

Office of the President of Shenlan Technology Industrial Park.

After Cao Mang came back, he took out a bottle of frozen happy water from the refrigerator.

"puff"

Unscrew the cap and the gas will immediately pour out from the mouth of the bottle.

"Gollum~ Gollum~ Gollum~"

Cao Mang drank half a bottle of Coke in one breath. The frozen liquid flowed from his throat, and his whole body suddenly became clear.

"Love you walking alone in a dark alley
I love you without kneeling

love you confronted with despair

Don't want to cry."

[Caller: Bao Xingxing, the person in charge of the sensor]

"What's the matter with Lao Bao?" Cao Mang put down the Coke and picked up the phone to answer it.

Bao Xingxing is the head of the camera sensor R&D department. This project was purchased on the system two and a half months ago.

"Mr. Cao, our RGBW sensor has passed the simulation verification." Bao Xingxing said excitedly.

"So fast?" Cao Mang said in surprise.

According to the system's estimate, it will take three months to develop this thing, but Bao Xingxing and the others developed it half a month earlier, which is a bit different from the usual situation.

"It succeeded by accident." Bao Xingxing said with a "hehe" smile.

"You first find a domestic foundry for tape-out, and then show it to me after the finished product comes out." Cao Mang said.

Even if he goes down at this time, he can only see the blueprints, and he has to find someone to manufacture the finished product.

"Okay, Mr. Cao." Bao Xingxing replied.

Perforated screen R&D department on the 3nd floor of Building 2, Deep Blue R&D Department.

After Zhou Youliang and his classmates returned to Shenzhen City, because Cao Mang had no work arrangements, they played games every day and had nothing to do, not knowing what to do.

Zhou Youliang, who was browsing the web, saw a pop-up window appear in the lower right corner of the computer.

The company's internal system received an email from Cao Mang, and all project leaders received an email.

The content of the email is roughly like this. Cao Mang first praised everyone, and then told all the project leaders that the company will give each team [-] million research funds.

After completing the project at hand, you can conduct research on the project you are interested in. This money is for the research and development expenses of each team. However, if you want to research any project, you must report to Cao Mang to get the money.

After all, the company's money does not come from strong winds, so you can't be allowed to study useless things.

If the project you are researching has a good prospect, you can apply to Cao Mang for an additional research fee.

Of course, the upgrading of original projects cannot be stagnated.

"Chaolin, Hongwen, Mr. Cao just sent an email, please come and take a look." Zhou Youliang said excitedly.

Seeing Zhou Youliang's excitement, Huo Chaolin and Xiao Hongwen immediately pressed the B button to return to the spring and ran behind him. They both thought that Cao Mang was going to give them a new task.

It has been a month since they came back from the capital.

If there is nothing else for them to do, they feel like they are going to be moldy.

"Damn it." Huo Chaolin and Xiao Hongwen shouted in unison after seeing the email.

"You said that our university talked about that thing, does President Cao agree with us to conduct research and development?" Zhou Youliang looked at the two people and asked.

"I think we'll know if we try it." Huo Chaolin and Xiao Hongwen said after looking at each other.

"Then I will make a PPT and send it to Mr. Cao first. I have decided that Mr. Cao will agree." Zhou Youliang said.

After talking, Zhou Youliang turned on WPS and started working on the project PPT.
