Control motherboard SMT assembly

    Intelligent manufacturing has entered the era of Industry 4.0, and industrial control technology is constantly innovating. The traditional control field is undergoing unprecedented changes and is beginning to develop towards networking. The industrial control of related products or components is developing in the direction of intelligence and networking.

    The industrial control motherboard has rich interfaces, including: RS-232/RS485 multiple serial ports, Gigabit Ethernet port, multiple USB, multiple audio and video input and output, multiple switch control and input signal detection, support WIFI, Bluetooth, 4G, etc. Data transmission, support user customized development. It can adapt to wide temperature environment, harsh environment, and long-term high-load work as needed.

    The main application areas of industrial control motherboards include: industrial equipment, GPS navigation, sewage online monitoring, air online monitoring, instrumentation, professional equipment controllers, military industry, government agencies, telecommunications, banks, electric power, vehicle LCD, monitoring, video doorbells , portable DVD, LCD TV, environmental protection equipment, etc.

    Commonly used industrial control motherboards are based on the ATX architecture, mainly including ATX motherboards, MicroATX motherboards, mini-ITX motherboards and EATX motherboards.

    1. ATX motherboard: ATX is a motherboard specification formulated by Intel Corporation in 1995. This is the first major change in computer case and motherboard design in many years. The more common ATX large motherboard, large rectangle, generally 7 expansion slots, the size is about 305x244mm. ATX boards are still one of the most widely used boards today and can be integrated with current applications employing ATX components. The expanded size offers the benefit of scalability while also including the ability to add wireless adapter options or sound cards as the application demands.

    2. MicroATX motherboard: a common large square, generally with 4 expansion slots, the size is about 244x244mm, MicroATX motherboard allows four PCI expansion slots, DIMM slots are 2-3, the width of the motherboard is reduced from the horizontal direction, and its total area is reduced. Small about 0.92 square inches.

    3. Mini-ITX motherboard: Mini-ITX is a compact and miniaturized motherboard design specification defined and introduced by VIA. At this stage, it is widely used in various commercial and industrial applications by various manufacturers. It is used to design professional computers for small spaces and small sizes, such as those used in cars, set-top boxes, and network equipment, but Mini-ITX motherboards can also be used to make thin clients. The Mini-ITX motherboard is similar to and backwards compatible with its predecessors, Micro-ATX and Flex-ATX, but it has several features that set it apart from its predecessors. A common mini-ITX motherboard is a small square, with 1 expansion slot, and the size is about 170x170mm. Due to the small size, there are limitations as fewer compatible electrical configurations and computing components are available compared to standard size boards with more space for advanced functions.

    4. EATX motherboard: EATX motherboard is the abbreviation of Extended ATX, which is mainly used in Rackmount server system. It is usually used in servers that are not capable of dual processors and standard ATX motherboards. The standard size is 12 × 13 inches (305mm × 330 mm), with 12 slots, and the volume is square. If it is a Xeon CPU, E5 or above Can also support 2 CPUs. . The fixing screw position of the upper part of the EATX motherboard is the same as that of the ATX, and it is mostly used in high-performance PCs and workstations. Wider than standard ATX, easy to route for 8 memory slots. Therefore, the 8 memory slots are the characteristic mark of the E-ATX motherboard, which can be used to assist in the identification (not 100%) when purchasing.
