1. View the I / O interface section
The I / O interface part of the motherboard of the industrial computer often reflects the positioning of a motherboard and the functions provided. Although for most users, the dual network card and 1394 interface provided by the I / O interface may not be used, but For users in need, this point is more important. At the same time, the number of USB ports on the motherboard of the industrial control computer sometimes affects the feeling of use, and the interfaces provided on the high-end motherboard are relatively abundant. After all, the configuration of any I / O interface part requires the user to pay for it. There is no need to consider the interface that is not needed, but the user must pay attention to the I / O interface part if necessary.
2. Check the motherboard type
The mainboard manufacturers of industrial computers introduced that the mainboard types of industrial computers are divided into two types: large board and small board. Even in the big board, there are several types of differences. Users need to pay attention that different versions of industrial computer motherboards have different PCB costs and expansion performance, which will affect the selling price of industrial computer motherboards. Among them, the integrated motherboard uses a highly integrated chipset, the basic characteristics of which are simpler layout and lower manufacturing cost. IPC motherboard manufacturers recommend choosing the motherboard type required for industrial production.
3. View workmanship materials
The work materials of the main board of the industrial computer are mainly viewed from two aspects: the workmanship of the PCB (printed circuit board), the quality of the PC board with guaranteed quality is basically consistent, the finish is good, and the general quality of the shiny and shiny looks better. The general standard for the number of PCB layers is four or six layers, of course, the quality of six layers is much better. The workmanship of SMT (surface mount) components mainly determines whether the production process of the motherboard is excellent by observing the mounting accuracy of certain components. The standard component placement is accurate and there is no offset.
How to choose the motherboard of industrial control computer? When choosing the main board of the industrial control computer, you should check the I / O interface part, check the board type, and check the work materials of the main board. At the same time, the choice of chipset is also considered when choosing the motherboard of the industrial control computer. The support provided by different chipsets of different motherboards is different, and the price is also different. You cannot choose a high-end one-sided and have high-end functions that you ca n’t use. Motherboard, you can not choose a motherboard that is not suitable for your needs because the map is cheap.
