Design and Selection of Main Board of Industrial Computer with Ultra-wide Temperature -30～70℃
The performance of an ultra-wide temperature -30～70℃ industrial computer is good or bad, and most of the technology is on an industrial motherboard. Many industrial PCs bought on Taobao generally use a four-layer board. In order to save costs, industrial control manufacturers on the Internet mostly use four-layer boards for their low-end motherboards, namely the primary signal layer, ground layer, power layer, and secondary signal layer.
Some manufacturers with a little conscience use a 6-layer PCB board with an auxiliary power layer and a mid-signal layer. Therefore, the 6-layer PCB motherboard has stronger anti-electromagnetic interference capability and the motherboard is more stable.
The main board of the industrial computer adopted by the Anrecson industrial computer is an 8-10 layer PCB board. Main signal layer, ground layer, power layer, secondary signal layer, auxiliary power layer, middle signal layer. In order to enhance the performance stability of the industrial computer, we will add one more layer of main signal layer, ground layer, power layer and sub signal layer in the design.
Ultra-wide temperature -30～70℃ industrial computer electronic materials selection
In order to ensure that the industrial computer can work normally and uninterrupted in an ultra-wide temperature environment of -30～70℃, the electronic components of the industrial computer and the structure are more thoughtful at this time. The Anrecson industrial computer guarantees normal operation in harsh environments (starting on during the lifetime, bad weather, humidity, vibration, dust, radiation, high temperature, etc.). The components of the industrial control motherboard need to be resistant to high temperature, low temperature, and moisture. In the electronic components, they are all carefully selected.
The structure design of the ultra-wide temperature -30～70℃ industrial computer
Industrial PCs used in ordinary environments are no different from commercial and household computers. If you work in an ultra-wide temperature range of -30～70℃, you need to pay more attention to color design.
Generally speaking, ultra-wide temperature industrial computers use fanless cooling methods. The CPU uses low power consumption. A copper or aluminum block with good heat dissipation is added to the surface of the CPU. The outside of the chassis is made of aluminum alloy shell, fin type design.
Anrecson's fanless ultra-wide temperature industrial computer uses aluminum or pure copper as the direct contact surface for heat dissipation of the CPU. There is a layer of thermally conductive silicone sheet on it. The thermally conductive silicone sheet directly contacts the fins with the large area aluminum profile. The heat dissipated by the CPU is directly transmitted to the large-area aluminum fins, creating an efficient heat dissipation method.
The housing structure is sealed and designed to resist interference from dust, smoke, and signals. It has corrosion resistance, high and low temperature resistance, and meets various harsh industrial field applications with long-term uninterrupted operation. Collard's ultra-wide temperature -30～70℃ industrial computer is widely used in machine vision, robotic arm control, AGV trolley, laser industry, rail transit, face recognition, environmental monitoring, medical treatment, ERP/MES/WMS and other industries.
