Blooming America

"The test is finally completed."

Rossi looked at the circuit board on the hand and then loosked a breath.

The printed circuit board is an electrical connection of electronic components. Its development has been more than 100 years; its design is mainly the layout design: the main advantage of the circuit board is to greatly reduce the errors of wiring and assembly, catching high levels of automation and production labor.

In the electronic machine, the green sè board is a printed circuit board, and the chip of the black sè (or silver sè) above the four four squares is an integrated circuit.

Usually, the color of B is green sè or brown sè, which is the Yan Sè of the solder welding (LDERMASK). It is an insulating protective layer that protects the steel wire or prevents the part from being welded to incorrect. A screen printing surface (Reen) is also printed on the solder resist layer. It is usually printed on this to print texts and symbols (mostly white sè) to mark the positions of each part on the board. The screen printing surface is also referred to as an icon surface (LEGEND) is installed in the formation of the final product, and the integrated circuit, the electrical crystal, diode, passive elements (eg, electrical resistance, capacitance, connector, etc.) and other various respective respective Electronic parts. By connecting through the wire, you can form an electronic signal link and thereby.

The printed circuit board and integrated circuit are not so good.

At that year, Catherine, it took more than ten years. Of course, she also had other things, she finally made the earliest apple TV.

However, in strict sense, the TV that has been made with transistors is said to be an integrated circuit TV ... It is still a bit unreliable. However, after the official production, although the initial process is used, it is also a first generation of integrated circuits.

Of course, it is more simple to make a printed circuit board than integrated circuits.

If an integrated circuit is represented as a human brain and body organ, then the printed circuit board is the body's skeleton and the foundation.

Although the skeleton is simple, the principle is very complicated.

Whether the length between the traces is equal, whether the signal may be disturbed, there is no designed defect, etc. These are needed.

And the printed circuit board just completely tried, is the new design of the company.

But this printed circuit board is not ordinary.

Because this printed circuit board is made with a supercomputer silver river.

B version,

That is, the printed circuit board, it is an important electronic component, which is a support of the electronic components.

Since the printed circuit board is not a general terminal product, it is slightly confusing in the definition of the name, for example: the motherboard for a personal computer, called the motherboard, not directly referred to as a circuit board, although there is a circuit board in the main board, but It is not the same, so it is not possible to evaluate the industry.

For example, as: because the integrated circuit parts are loaded on the board, some people call it as a panel, but it is essentially that he is not equivalent to the printed circuit board.

As the integrated circuit is getting more complicated, the design of the board itself will become more complicated. At this time, how to consider using the least material, the most stable circuit design, etc., it is also increasing The more test the level of technical personnel.

One piece of integrated chip, there are often more than a dozen, or even dozens of pins, then these pins should access resistance, capacitance, power supply, etc. These problems, the income of the project is hard to imagine. .

And once the design is designed, the circuit board has a defect on the circuit board. At this time, it is necessary to use additional lines to weld one by one. This is a flying line. This situation is very serious for an electronic product. The problem is very serious and deadly.

But now is not the case.

This situation has been changed after the current Galaxy Supercomputer appears.

A software specially designed B circuit board has been developed. This software can automatically generate a printed circuit. This circuit is because it is automatically generated by the computer, so its circuit will not be affected by the habit of the human brain. Instead, it will be changed according to the outside environment.

As long as the functionality of each pin of the electronic component is set, the software will optimize according to the software of the device.

Of course, this function is still very perfect, but it is still possible to assist in the design of the optimized circuit trace.

The board on the Rossi hand is the first piece of finished product.

This is a single board motherboard.

- This will be a masterboard of a leather.

The current computer motherboard is a double layer.

Because of the reasons involved, in order to accommodate enough electronic components, the motherboard is made very huge.

But in this case, it seems that it is not suitable in the chassis, so it is designed to become a double-layer motherboard mode.

And this result is in the design of the motherboard, there are many unnecessary designs, and such a design, while damaging the system xìng, it is more aggravated the computer's weight, the heavy weight of the computer is also It is worthwhile to be one of the elements of people.

The board motherboard that is designed is not the same.

It is only necessary to integrate all the electronic components, so that the circuit system can make the circuit system more stable, efficient, and can reduce the weight of the machine. This B board, from the perspective of the process and design, it can be said that it has reached the limit of the current B board design.

Before the printed circuit board appears, the interconnection between the electronic components is directly connected to the wires, and the complete line is composed. Now, the circuit breadboard is only existed as a valid experimental tool, and the printed circuit board has become a printed circuit board called the printed circuit board in the electronics industry.

In the early 20th century, in order to simplify the production of electronic machines, reduce the wiring between electronic parts, reducing the advantages such as production cost, so that the method of replacing the wiring in printing. In the past 30 years, an engineer continues to propose a metal conductor on an insulated substrate for wiring. Finally, there is a current printed circuit board era.

Rossi took the electronic instrument. The first is to check the circuit, although the software design is very clever, if there is a problem in the basic wiring, it can be bad.

Of course, this is just for insurance. When the product is software design, the engineers have checked the software, and the circuit board that is designed by the circuit has also been a variety of theoretical calculations.

And now, this finished product is in Rossi.

The design of the printed circuit board is based on circuit schematic, thereby achieving the functions required for circuit designers. The design of the design of the printed circuit board is designed. Excellent layout design can save costs and achieve good circuits xìng energy and heat dissipation. Simple layout design can be implemented manually.

Complex layouts are a test for people now, but in the future, it is achieved with computer-aided design (CAD).

Now this software is a software, but it is clear that the grass-making stage is not a smooth sailing, and there have been a lot of waste boards in Rossi. Fortunately, this board does not seem to have a problem.

But Rossi did not detect the error, and it did not mean that this board was fine.

Even if there is no error, after connecting the original connections such as chips and capacitors, the entire device will conduct a major inspection, which will not only only hardware checks, but also the software inspection.

Even if the line is no problem, it does not mean that the product that is finally played is no problem.

The current board is not a mature product as the 21st century, which is an emerging product. The current development of the Jiwei circuit B is less than ten years. So some cautious problems must be considered.

Moreover, this design is now the original double board structure into a single board structure, and the double board structure will be eliminated by history, which is the fact.

"Probably no problem ..." Rossi took the report of the test, and then painted a hook on it.

In this way, his mission is completed, and then he will give it to the following to continue engaged.

The plan is to complete the division of labor, which is also an efficient management experience of the company.

This motherboard needs to be placed in the case of strong magnetic fields and strong interference, and it is also necessary to try anti-interference.

Catherine does not require its own board to do it from the four floors, but the quality requirements are definitely needed.

In particular, a cloud system has now occurred, so it is necessary for personal computers in quality.

Both must reflect differences, this is the requirements of Catherine.

On the other side, Catherine is working on Japan.

Wait until July, Catherine is going to Japan.

It's hard to have a good day, Catherine decided to go to Japan's Expo to see, and then make a little fake.

Catherine found that he had not been fake for a long time. I have to know that she has taken a vacation for a year!

Of course, the objective conditions are not allowed, but it is still very dissatisfactory.

As for the box office of "Ling Hún Reaction II", this Catherine is not worried, from the opening of the box office, this year's spirit hún reactive results and last year, if there is no accident, earn billion profit, nor can it be.

"Kate, it is done, this is our new visa."

Elsa handed a visa to Catherine.

"It seems that we can move right away." Catherine is also very satisfied.

The 1970 Okue World Expo is very famous. The World Expo is the first World Expo, which is also the same as the mine of the United States to show the grand event in front of the public.

How does Catherine can let?

"It's next month ~"

She decided.

The batter passing by the circuit board is a bitter pass ... @.
