Micro step president Zhang Yong: in social science, in general we usually put the from the aspects, the overall aspects to study and grasp the scientific, called macro science and the research method, called macro approach. Usually, the research on the science from the aspect and the local aspect, is called the micro science, this research method, is called the microscopic method. For the motherboard industry as a macro view, the need for the motherboard micro view to stay!

There is a saying called "ears, seeing is believing, I very much agree with this sentence. Our body has a lot of organs to perceive the outside information, but the eyes are the most part of the trust. Through our eyes, we can see the different colors, see the different shapes, see what you like, and you can see that you don't like or even feel afraid.. It can be said that without the eyes, our life will be eclipsed.

But seeing is real, "this sentence is not without flaws, to micro step 2013 the latest research and development board WTM-I2H we can cognitive to the picture we see, but our cognitive will limited to what we see in the picture. In the places where we can see, sometimes we tend to ignore their existence.. But it doesn't mean that they don't exist, but that's what's gone in our sight.. Even in the eyes of us, when you look at it in a different angle, the image in your eyes is probably very different.

A micro micro vision board

We don't see things, a large part is beyond our visual resolution limit of the very small things that we refer to as "miniature landscape. Many of the things that we take for granted, when we zoom in on the details, we also explore a different landscape.. The miniature landscape photography, even as a career or even a kind of art. No matter what the objects are, when we to micro perspective to re-examine, you will find and daily to see very different place, of course, motherboard, too, so today I talk about the topic is on the motherboard micro world. In this paper, the author through the camera and lens, from the micro perspective to introduce different motherboard. Perhaps it will be found that we see the motherboard every day, there are also many places we have never learned.

From another perspective, you'll have a new discovery.

PCB said the motherboard, there are a lot of players to talk about a topic, and that is the number of PCB. Motherboard design due to consider the layout of the very many components, but also consider the wiring rationality and anti-jamming performance, so are the multilayer PCB design, even in some high-end motherboard, the number will change more. And many people also take the motherboard PCB as a measure of its positioning standards.

In fact, if we go carefully to see the cross section of the motherboard PCB board, will find the number of PCB in fact the motherboard than we imagined a lot more. Because we usually say that the number of the motherboard PCB, PCB is the number of power or transmission signal. But in addition to the power supply layer and signal layer, PCB also includes solder layer, silk screen layer, isolation layer, etc.. Even the most despised of the 4 layers PCB board, its actual number will also be like thousands of cake as let the number of people come to.

So, whether it is the 4 layer, the 6 layer or more layers of PCB, in order to meet the layout of the components of the case, in fact, and the number of layers is no relationship. So when we talk about the motherboard PCB again, must not forget the actual number of PCB is actually much more than the number of layers marked.

PCB in so many tiny spots......

The motherboard mounting hole secret

In the process of installing the motherboard, many friends will find a detail, and that is the motherboard screws on the installation of the hole will have a circle of metal layer. The metal layer has a certain thickness, and the screw is closely associated with the screw.. Many people don't understand why there is this thing on the installation hole.. In fact, the PCB manufacturing process has specially increased tin layer. This allows the motherboard to contact with the installation of the screw after the installation, the motherboard grounding effect.

So both screws, or pillars, the chassis or, can be as a motherboard connected object so as to ensure the electrical performance of the motherboard, and to protect the motherboard does not by the current damage. So don't underestimate this simple design, which may be more important than you think. Next time when you installed, you can look at the small details.

You look at these pins?

USB extension pin, front panel, Headset interface extension expansion pin pin...... These we often use the pin, for friends who often installed the computer, how to connect the pin can be said is hundreds of times. But in this pin we have used to be accustomed to on, and we do not know where.
