How to select the type of industrial control motherboard?

It is well known that the core of both commercial and industrial computers is the motherboard, while the industrial motherboard has a wider range of applications and a worse use environment. Therefore, users have higher requirements for its function, compatibility and reliability. So how do we choose the type and determine the advantages and disadvantages when purchasing the industrial control motherboard? With years of experience in industrial computer production, industrial control motherboard manufacturers share some experience here.

1. Motherboard layout

The layout of the IPC main board is mainly reflected by the arrangement of the components on the IPC main board and the wiring of the lines. A good industrial computer motherboard is almost a beautiful work of art in the eyes of experts. Now, in order to save costs and reduce prices, some industrial PC motherboard manufacturers can gain a firm foothold in the market. They not only reduce the number of board layers, but also make corresponding adjustments to the materials and accessories of industrial PC motherboards, which only meet the basic performance requirements of chipsets. This way of reducing costs is a test of the manufacturers' ability to design and layout industrial PC motherboards. Put the same number of expansion bits in a smaller space, and also maintain stability and limit interference, so the rationality of the structural arrangement and design of the industrial control computer motherboard is particularly important. A little bit of unreasonable design will lead to a crash. In this regard, manufacturers with weak strength are easy to make mistakes in these places. The instability and poor performance of the motherboard are all caused by this! So when we choose manufacturers, we must choose manufacturers that have been working for many years and have excellent technology.

2、CPU

The choice of chipset is the first consideration of motherboard selection. The support provided by different motherboard chipsets is different. At the same time, the price is also different. You can't choose a high-end motherboard with high-end functions that you can't use at all, nor can you choose a motherboard that is not suitable for your needs because of the cheap picture. The principle of motherboard selection is: "fit yourself, meet your needs".

3. Interface configuration

The interface part, in many cases, also reflects the positioning of a motherboard and the functions it provides. Although for most users, the dual network ports and multiple serial ports provided by the interface may not be able to use, but for users who need it, this point is more important. At the same time, the number of USB interfaces sometimes affects the feeling of use. In the interface part, it can well explain the positioning of a motherboard. The interface provided on the high-end motherboard is relatively rich, while on the low-end motherboard, it is not a bad thing to save. After all, any function ultimately needs to be paid by the user, and unnecessary interfaces are unnecessary, but if necessary, we must pay attention!

4. Working materials

The work materials for the main board of industrial control computer are mainly from two aspects: 1. The work of PCB (printed circuit board). The color of the PC board with guaranteed quality is basically consistent, and the smoothness is good. The general quality of the glossy PC board is relatively good. The general standard for the number of layers of PCB is 4 or 6 layers, of course, the quality of 6 layers is much better. 2. Manufacturing of SMT (surface mount) components. It is mainly to determine whether the production process of the motherboard is excellent by observing the mounting accuracy of some components. The standard components are accurately mounted and positioned without deviation.

How is the performance, compatibility and reliability of the motherboard tested? These works are generally completed by the design certification department of the R&D team. In comparison, the performance test is easier. The test bench can be set up with simple equipment such as CPU, memory module, hard disk and power supply. The key is to carefully test each performance item by item. However, compatibility testing is much more complicated. It really requires a lot of money, manpower and time to test the compatibility of the motherboard with the popular mainstream operating systems, industry application software and devices on the market. For industrial users, the most important thing is the reliability of the motherboard. Reliability test includes high temperature test, low temperature test, humidity test, vibration test, drop test, anti-static test and lightning test.
