The importance of power MOSFET in motherboard development and design


The importance of power MOSFET in motherboard development and design

First of all, the layout of the CPU socket is very important. There must be enough space to install the CPU fan. If it is too close to the edge of the motherboard, it will be difficult to install the CPU radiator in some cases where the space is relatively small or the power supply position is unreasonable (especially when the user wants to change the radiator but does not want to take out the entire motherboard) . In the same way, the capacitors around the CPU socket should not be too close, otherwise it will be inconvenient to install a radiator (even some large CPU radiators cannot be installed at all).


Motherboard layout is critical

Secondly, if the components such as CMOS jumpers and SATA that are often used on the motherboard are not properly designed, they will also become unusable. In particular, the SATA interface cannot be on the same level as PCI-E because graphics cards are getting longer and longer and can easily be blocked. Of course, there is also a method of designing the SATA interface to lie on its side to avoid this kind of conflict.

There are many cases of unreasonable layout. For example, PCI slots are often blocked by capacitors next to them, making PCI devices unusable. This is a very common situation. Therefore, it is recommended that when purchasing a computer, users may wish to test it on the spot to avoid compatibility issues with other accessories due to the layout of the motherboard. The ATX power interface is usually designed next to the memory.

In addition, the ATX power interface is a factor that tests whether the motherboard connection is convenient. A more reasonable location should be on the upper right side or between the CPU socket and the memory slot. It should not appear next to the CPU socket and the left I/O interface. This is mainly to avoid the embarrassment of having some power supply wiring that is too short due to the need to bypass the radiator, and it will not hinder the installation of the CPU radiator or affect the air circulation around it.

MOSFET heatsink eliminates processor heatsink installation

Heat pipes are widely used in mid- to high-end motherboards due to their excellent heat dissipation performance. However, in many motherboards that use heat pipes for cooling, some heat pipes are too complex, have large bends, or are too complex, causing the heat pipes to hinder the installation of the radiator. At the same time, in order to avoid conflicts, some manufacturers design the heat pipe to be crooked like a tadpole (the thermal conductivity of the heat pipe will drop rapidly after it is twisted). When choosing a board, you should not just look at the appearance. Otherwise, wouldn't those boards that look good but have poor design be just "showy"?


Excellent motherboard layout makes it easy for users to install and use the computer. On the contrary, some "showy" motherboards, although exaggerated in appearance, often conflict with processor radiators, graphics cards and other components. Therefore, it is recommended that when users purchase a computer, it is best to install it in person to avoid unnecessary trouble.

It can be seen from this that the design of MOSFET on a motherboard directly affects the production and use of a product.
