Identify the motherboard.

Now the reader of the work of the motherboard is very important, often buy the motherboard to see the work and materials, only to see the pleasing to buy. However, the motherboard to make the materials such a problem is somewhat abstruse, many junior enthusiasts often do not know which design is good, which is bad, so buy things can only rely on the online Word-of-mouth transmission, information is not reliable.

In fact, the design of the motherboard is good, can be seen through some very simple places, such as the interface of the brand, the location of parts, such as the line.

Some friends said, these are appearances, really can rely on these places to see the board's good or bad? Tell you, these methods are many enthusiasts in the actual use of the experience summed up, although not professional method, but for ordinary computer enthusiasts are fully enough.

Generally speaking, look at a motherboard, just look at three places on the can:

　　Method 1--look at the overall layout

Well-designed motherboards, put aside the materials used to work do not talk, see the overall layout, including the placement of chips, capacitors and connectors location arrangements are learned, some time ago, a certain brand computer has a flying line problem, in fact, is the layout of the problem, is the design team strength or not very attentively.

If a board layout messy, to achieve a function of the chip and the corresponding capacitance resistor, such as the distance between the components, the motherboard circuit is bound to appear crossover and interference, which will affect the stability of the system and overclocking ability.

For example, the location of various interfaces, usually the best way is to put all the interface on the edge of the board, so that easy to plug. If the IDE interface of a motherboard is placed in the central position of the motherboard, obviously does not conform to the standard, because this is bound to cause the IDE line to other devices such as CPU fan and various expansion cards, such as entanglement and conflict, such a board is obviously the design of the time is not considered, the use of the process will cause a lot of unnecessary trouble.

On the other hand, the motherboard layout also has a part spacing problem, if some slots and other parts of the distance too close, it may affect the memory or graphics and other parts of the installation, such as the board in the above may be difficult to install the larger radiator.

Good motherboard overall layout of the streamlining summary is: small but not disorderly, tight and orderly parts. Today's motherboard products pay attention to reducing production costs, trying to produce the best products at the lowest cost. It was not recommended that the cost-nlx of the previous practice. Look at the layout needs to have a certain skill, we can compare to produce a feeling, see a similar motherboard in a flash can see the level of the grade.

　Method 2--Look at PCB

The board of Materials contains many aspects, PCB is an important aspect. A simple way to identify the PCD plate is to look at the number of layers, in general, more than the number of layers of the motherboard between the various parts of the collision and the probability of conflict is smaller, so that the motherboard's stability and overclocking ability will correspondingly improve a lot. Usually, the board's PCB layer must reach at least four layers to meet the needs, and high-end motherboards usually use a high price of six-layer board or even eight-layer board.

However, PCB board layer is difficult to identify with the naked eye, some PCB version of the thickness is very small, but is very advanced 8-layer board. However, this is not to say that we can not identify the quality of the PCB, except for a variety of mobile device motherboards do not say that the ordinary desktop computer motherboard is still visible.

Good PCB thick and flexible, thick does not explain the number of PCB layers, and the more the lower the number of boards thicker. But with the flexibility of this indicator is not the same, good PCB in production will take into account the impact of stress, such as you screw or install equipment, the PCB to be able to withstand a certain bending, otherwise it is easy to damage. The general level of flexibility of the 4-layer plate is limited, the number of layers up to 6 after the degree of flexibility will increase.

Need to explain is that the color of the PCB can not represent quality, color is only a layer of antirust paint, the main protective effect, what color. The black or blue boards are now popular, but many of the real high-end motherboards are still dark green in the past.

Method 3--look at the materials of parts

One of the most important types of materials that affect the quality of the motherboard is capacitance and connectors.

Capacitance in the main board to ensure the voltage and current stability of the filtering function. The common capacitors on the motherboard are tantalum capacitors and aluminum capacitors (electrolytic capacitors). Aluminum capacitance is large, the price is low, but it is susceptible to temperature, the life is relatively short, and with the use of time will gradually become ineffective. tantalum Capacitor life long, high temperature, high accuracy, but small capacity, high price. Because of the higher precision of tantalum capacitors, at the same time the price is more expensive (usually a tantalum capacitor may be the price of aluminum electrolytic capacitor several times) so tantalum capacitors are usually used to some of the higher prices of high-grade motherboards, if you buy a low-cost motherboard with a number of tantalum capacitors, Then the board's material reliability scores will be higher.

This is a mid-range motherboard of the power supply, large capacitors and small capacitors with each other to ensure the purity of power supply.

However, this does not completely negate the benefits of aluminum electrolytic capacitors, in fact, because of the high cost and capacity constraints, the main board capacitor is to be a major part of electrolytic capacitor, and electrolytic capacitor itself is also hierarchy. Generally speaking, the current motherboard capacitance can be divided into three grades, the first grade is represented by the Rubcon, such as the Japanese capacitor, the second grade is a number of Taiwan's major manufacturers of the Taiwan system capacitors, other small factory products classified as the third grade, the price of the three are also in turn, the grade, Usually the company's high-end motherboard products will be the overall use of the Japanese high quality capacitors, but also some manufacturers for the quality and stability of the low end products in the use of the Japanese capacitor.

Capacitance may be the focus of controversy for many enthusiasts, such as aluminum capacitors and tantalum capacitors. The better question has been discussed countless times. Small knitting here to say is that the use of high-grade materials to be coupled with sophisticated design, small family of NEC brand machine motherboards are almost all aluminum capacitors, from 99 factory used to now, suffering from the ordeal has been used still good, life is no worse than tantalum capacitors.

In addition to capacitors, the motherboard on the connectors is also an important link, good plug-ins are also brand, Foxconn is the most used products, the best quality. Other amp products are also good. If your motherboard plug-in is some do not know the brand of small brands, the grade of the Board can be determined basically not high.

One penny, one penny.

In general, the Board of the grade to see the above three aspects is almost. Of course, the actual situation is that you have to do a lot of kanban introduction, when necessary to go to the market to see more of the board. We have a saying that "a long illness into a doctor," You see more, you are proficient.
