"Boss, the diaphragm has been formed. Please go over and take a look."
Just after finishing the call with my sister Zhou Feifei, a newly recruited college student knocked on the door outside the office. After receiving permission, he immediately opened the door and walked in, asking for his instructions.
Zhou Feiyu nodded, and then went down with the other party.
After a while, the two walked into the R&D workshop opened by the factory. It was now very luxuriously decorated, with almost all kinds of equipment in place, and there were more people than the two or three big cats and kittens at the beginning.
During this period, in addition to Fei Yang Optics, Fei Yang New Material was also recruiting people. Zhou Feiyu arranged for the newly promoted personnel manager to go to various universities in Jiangnan Province for a round of school recruitment.
Fei Yang New Material has hired ten R&D personnel alone, and this is after careful selection.
Thanks to the sanctions imposed by Eagle Country, Fei Yang New Material became famous and is now well-known to many university students.
After the round of school recruitment, hundreds of college students came to apply, and almost all of them had strong intentions.
The college student who knocked on the door just now is Jiang Fan, an outstanding graduate in materials major recruited from Nanjiang University, who is also a junior student of Zhou Feiyu.
After entering, Jiang Fan brought Zhou Feiyu to an experimental equipment. It was relatively simple. It looked like a computer host with no screen. There was only one piece of light glass placed in front of the equipment. This was a 24-inch piece of light glass with a brown background and transparent color.
There is only a simple flexible circuit board as thick as a thumb pulled out from the light glass and connected to the device, but there are no other connections.
Next to the light glass, there are three pieces of brown-black film, which are relatively thin. Each piece has a large area, but the thickness is only 0.2 millimeters, but it has a solid thickness that can be felt by hand.
"Boss, this is a diaphragm made according to your design. It is made of FY-02 as the base material, FY-01 material and some newly prepared diaphragms. The upper and lower surfaces are transparent Release Film... This film is difficult to make, and the yield rate is too low. It either has impurities or shows problems such as discoloration, delamination, and electrostatic accumulation. We invested ten times the raw materials, but we only got these three pieces of material..."
Jiang Fan pointed at this brown-black sheet and introduced it in very detail. Some production details and problems were also explained. It was obvious that a lot of effort was put into it.
"It doesn't matter, it's always like this in the research and development stage."
Zhou Feiyu didn't pay attention to these details.
There are bound to be many problems in the early stages of any product development.
It's normal if there are problems, and it's abnormal if there are no problems.
The absence of problems does not mean that the product is designed to be seamless and flawless. On the contrary, there is only one possibility, and that is that no problems are found.
The devil is hidden in the details, which is a step that any industrial product must go through in mass production.
When a problem occurs, it means that the problem has been discovered and can be improved.
Only when one problem is solved and one problem is eliminated will the product be closer to perfection and steadily reach mass production standards.
This is why all products must go through samples and trial production before mass production. Many products, such as mobile phones, actually go through a research and development cycle of six months to one year before being mass-produced and launched. During this period, they will go through at least three to four rounds of trial production. Like Zhongzheng Mobile, in addition to rounds of trial production, there will also be a large-scale trial production before mass production to make tens of thousands of mobile phones.
Jiang Fan then introduced the 24-inch piece of glass, "This is optical glass molded and made by a glass factory that Mr. Jiang found. They also provide flexible circuit boards."
"Okay."
Zhou Feiyu nodded, indicating that he understood.
Then, he picked up the three pieces of brown-black film and looked at it. The background color was very pure, as if there were no impurities, and it made people feel comfortable looking at it. In addition, these three thin films do not transmit any light at first glance, and they are obviously excellent in light shielding and reflection.
Zhou Feiyu couldn't help but nodded again.
These three thin films may look a bit ordinary, but the technology used in them is extraordinary. Except for him, the designer, no one can understand it, and no one can independently disassemble and analyze the principles.
Among them, FY-02 is used as the base material, some of the principles of FY-01 are used, and then other advanced technologies in "Basic Optical Film" and "Intermediate Thin Film Technology" are used, as well as the inspiration of Zhou Feiyu itself.
He arranged for Jiang Xinyi to make the light glass, and the molding fee cost tens of thousands, and it was also Jiang Xinyi's relationship. Otherwise, if it were negotiated in the name of Fei Yang New Material, it would be impossible to negotiate without more than 100,000 yuan. Well, this kind of optical glass is no better than Mobile Phone Glass. Opening a mold requires tens of millions or more, because Mobile Phone Glass needs to match high-end chips, but this kind of optical glass does not require a chip, it only needs a simple mold, and then inject liquid crystal between the glasses.
"Cut out three 24-inch pieces from these three pieces of film, and then start applying the film."
After the inspection, Zhou Feiyu told them to get started.
"Okay."
Jiang Fan responded quickly, and then worked with the other two R&D personnel to cut it according to size.
After a while, three 24-inch film sheets were cut, and then the film sheets were attached to the 24-inch light glass in a specific order, direction, and angle according to Zhou Feiyu's design plan.
After the three diaphragms were pasted, the originally transparent light glass became pure black. At first glance, it looked very pure black. The light was completely blocked and reflected, giving it a crystal clear feeling, which was very beautiful.
Soon, Jiang Fan started the experimental equipment and turned on the power switch.
As the indicator light turns on, the voltage and current immediately enter the 24-inch pure black glass through the flexible circuit board.
Uh-huh!
Silently, the twenty-four-inch pure black glass was lit, allowing light to pass through.
"It's like a dream, not bad!"
Zhou Feiyu stood directly in front of the glass. When the glass was lit, the light passed through the glass from behind and then entered his eyes. The light that should have been flat and unable to be truly felt now seemed to become smart lines, flying and changing in the air, like the light in a dream.
Zhou Feiyu couldn't help but look happy, then he closed his left eye and looked at the right eye one after another.
When the left eye is closed and the right eye is opened, the light that the right eye sees through the glass is partly bright and partly dim, resulting in distortion and a strong sense of layering, but it becomes extremely dull.
But when he closed his right eye and opened his left eye, the light cast by the glass that his left eye saw was completely different from the light that his right eye had seen before. The originally bright places were now dim, and the originally dark places were now bright. On top of that, the twists and layers are completely reversed. However, the light at this time is also dull.
Finally, both eyes opened at the same time, and the light danced and moved again, as if it was alive.
This visual sense is very wonderful.
