BGA industrial control motherboard assembly

The industrial control motherboard is a motherboard used in industrial occasions. It is adopted by industrial computers. It can adapt to a wide temperature environment according to requirements, can adapt to harsh environments, and can work under high loads for a long time.

Fundamental contents

The so-called industrial control motherboard

①CPU can be a common plug-in type, or a part of it is a board-mounted type. The main reason is to see

②Memory slot is usually 1-2

③Integrated graphics card

④There are many I/O devices, but some motherboards will omit the printing port

⑤PCI slot is usually about 2-3

⑥Plate type is relatively small

The motherboard that really meets the industrial control standard is divided into two parts!

The first part is the "Industrial Control Motherboard" part! ! The function of this part is the same as the motherboard we use! ! However, the industrial control motherboard is designed as a card! It's like a giant graphics card! ! There are two rows of gold fingers on the bottom of the motherboard! However, this section does not contain any expansion slots!

The second part is the "Expansion Interface Board" part! There are several PCI and ISA slots on it! ! There is also a slot for connecting the "industrial control motherboard" !

During the actual installation, the "expansion interface board" is fixed on the bottom plate of the chassis! And the "industrial control motherboard" is plugged into the "expansion interface board"! However, this structure is helpful for adding multiple PCI or ISA devices.

BGA industrial control motherboard assembly Characteristic

Working temperature and heat dissipation: Industrial control motherboards can work stably and without failure between -20°C~60°C, and even some industrial control motherboards adopt special wide temperature design, and the temperature range can reach -20°C~70°C. This is a severe test for the heat dissipation scheme and heat dissipation efficiency of the organization. In the heat dissipation design of the industrial control motherboard mechanism, an all-aluminum mechanism shell and a special heat dissipation design must be used, and special treatment must be carried out for large heat generating units such as the CPU, north and south bridges, and hard drives to ensure the normal operation of the industrial control motherboard and the whole machine.

Management: In addition to providing similar remote connection management, the industrial control motherboard can also realize remote unattended automatic power on and off. Through the embedded IPMB and SMNP-1000 modules, the management, recording, and transmission of real-time system operation information can be realized.

Protection function: Through special design, the industrial control motherboard can realize the functions of the automatic restart of the watchdog and anti-surge impact in case of abnormal conditions such as crashes, and fully guarantee the high stability of the system in harsh environments.

Market size: Industrial control motherboards are mainly customized products, with relatively small output and market size, and the cost of switching to other brands of motherboards is high. Therefore, users who choose industrial control motherboards generally do not easily switch to other brands.
