The difference between industrial motherboard and commercial motherboard

According to the main purpose, the motherboard can be divided into the following two types: industrial motherboard and commercial motherboard. The commercial motherboard is mainly for home and home computers, while the industrial motherboard is mainly for industrial fields, so there is a big difference in the concept of scientific research, development and design between the two. So what are the differences between them?

Industrial control main board

Usage time: The commercial motherboard will be upgraded after two to three years of use. The target value of the commercial motherboard market is: faster speed, good graphics game effect, and affordable price. Compared with commercial computers, the use of industrial computers is quite different. In the field of industrial application, each type of machine and equipment will have a fixed task. In the case of clear application, the speed and image processing function of industrial computer can be determined, and there is no need to upgrade from time to time. Compared with speed and price, industrial consumers are more concerned about mainboards that can work stably for a long time. Therefore, the service life of the industrial motherboard is usually five to eight years.

Material selection of electronic components: the main board is an integrated circuit board, and the key of integrated circuit board is a variety of electronic components. Due to the difference in service time between industrial motherboards and commercial motherboards, there is also a big difference in the selection of electronic components. The stability and use standard of electronic components of commercial motherboards is lower than that of industrial motherboards. What we yearn for is the timeliness of products. Commercial-grade products are commonly used in the materials of electronic components.

For example, capacitors, commercial motherboards are mostly made of ordinary capacitors. First, they are based on the use of commercial market products, and second, they are based on the cost reduction of motherboards. The electronic components of the industrial motherboard must be suitable for a wide temperature environment (- 40 ℃~75 ℃) to ensure normal operation in a complex environment (long-term continuous startup, vibration, dust, radiation source, etc.). In addition, the electronic components of the industrial motherboard also need to be heat resistant and moisture resistant. In order to meet the application needs, the industrial mainboard uses high-quality chip electrolytic, tantalum and ceramic chip capacitors. This is one of the reasons why the price of industrial mainboards is higher than that of commercial mainboards.
