For example, the Intel Pentium 75 processor has 775 pins. Fortunately, the chip needs to be punched, and it is automatically soldered by the mounter.
These stitches have to be punched before they can be inserted, and the pavement is a three-layer composite plate. It is very complicated for a designer like her to have holes to be punched and half stitches to connect the mezzanine road.
Most of these components are inserted manually, and each person inserts two or three kinds, which requires Liu Meijuan to teach them by hand.
However, some components do not have long pins to be directly bonded to the road board by the mounter. For example, almost all chips are suitable for mounting the motherboard because of too many pins.
What we do is to go through the process of mounter first, then manually insert components, and then wave soldering machine automatically welds them.
This welder will not work until Liu Meijuan inputs the drawing data.
Finally, it is necessary to manually repair the welding and even change the welding data at the place where the road slab is detected to have false welding and desoldering.
All this was done by Liu Minjuan after her internship in a motherboard factory, otherwise she wouldn’t do it if she had a theory.
The whole process is the most complicated and complicated. It took Liu Meijuan ten days to produce the first qualified brain motherboard.
This motherboard is not simple. It’s the only one in the world. This is Liu Meijuan’s knowledge of Intel Pentium chips. The basic pertinence has been greatly strengthened and security precautions have been taken.
For example, a second-level buffer is added, and a dsp high-speed calculation auxiliary module is added. This module is mainly to strengthen the game dynamic calculation, and many later generations will have advanced algorithms.
In terms of graphics and sound processing, she can buy the best graphics cards and cards today because she doesn’t have her own chip.
However, after improvement, she made a pluggable design, leaving room for upgrading.
The most important thing is that Liu Meijuan has to design a bs management chip, which is actually an R chip. Once it is set, it cannot change the data.
Bs chip is an industry-recognized standard of ib company’s P concurrent machine, which is that all external devices of the main board controlling the brain must be recognized by it, which is the reason of brain-computer self-test.
It is precisely because of this that a dolphin company can send a data interface to a certain device, which can further improve the performance of peripheral devices and reduce the self-checking time.
The overall performance ratio of public interface is just optimized for a certain peripheral device.
For example, the display and architecture keyboard, mouse, floppy drive, CD-ROM drive, hard disk and so on are specialized equipment, so there is no need to make a public interface.
There is also the most important security management to prevent the back door of Intel Pentium chip from leaking and transferring data. All this needs to be done by designing a special bs chip.
However, all this is beyond the understanding of ordinary engineers. In this era, people and even countries may not have such engineers. These are the secrets of western brain manufacturers.
However, it was later that the brain performance developed too fast, and many technologies of these antique brains were made public, because there was such a specialized enthusiast forum abroad to discuss these technologies, and Liu Meijuan didn’t know this knowledge.
It can be said that this new motherboard designed by Liu Meijuan is definitely the best in game performance and graphics performance in the world today. None of the motherboards can run a real game in the world without problems such as jamming and delay.
It is not enough to have a motherboard alone, but also to have an active management module, a computer external socket, a management module, a chassis shell, an architecture keyboard and other self-developed components.
There are a lot of these things, and Rome can’t be built in a day.
Chapter seventy-one Report
While Liu Meijuan was busy with technical guidance, Zhang Zhidong finally got through the tutorial work, and he could do graduation theory while working.
It is very difficult to do this job, and ordinary students are not qualified. After all, mentors are mentors, and students’ mentors are naturally unequal.
However, Zhang Zhidong’s natural endowment was very popular with his tutor, and he agreed to take him to graduate school in person.
Zhang Zhidong was arranged by Wang Yong, and Chen Shufen was in charge of managing the technician’s construction period of South China University of Technology. She sent a car to pick him up with Chen Shufen.
Chen Shufen received him warmly.
"hello! My name is Chen Shufen and I am the secretary and assistant of Director Liu. "
"Hello!" Zhang Zhidong can’t communicate simply and said hello.
"The company is very busy at this time, and neither the chairman nor director Liu has you. If you want to see them, I can take you there."
Chen Shufen knows that Zhang Zhidong is the only software engineer recruited by the company. She attaches great importance to it and is willing to take him to see them at the risk of disturbing the Wang Yong couple.
"It’s better for me to do things without talking about the chairman. I want to see Director Liu and ask her to arrange work for me."
Zhang Zhidong is a technical house, and he has almost no hobbies except work.
"I’m sorry I’m afraid you’ll have to wait a few days for the company to trial-produce the car. "
Chen Shufen means you don’t have the tools to do things if you want.
"The trouble Chen secret take me to production car! I also have a little research on hardware, and I want to see our company’s dolphin brain. "
"No problem" Chen Shufen readily agreed.
Although Zhang Zhidong has seen real photos of the company, the actual office environment still shocked him a little.
It’s not so much an office as a high-end leisure club here, which is a luxury.
There are many components on the road board, including pin diodes, triodes, resistors, and so on.
