Industrial motherboard and commercial high -precision circuit board pcb board with distinction , commercial PCB board motherboard using ordinary electrolytic capacitors, mainly to reduce costs motherboard. Industrial motherboard components require temporal temperature environment (-20 ℃ ~ 60 ℃), to ensure that in the harsh environment ( permanently switched lifetime, bad weather, moisture, vibration, dust , radiation, temperature, etc. ) to work ; motherboard components require high temperature, moisture resistance, and so on. High quality SMD electrolytic , tantalum , ceramic capacitors.
The high-precision industrial motherboard PCB circuit board : Commercial motherboard uses a 4- layer pcb design , the general PCB board divided into four , and two top most layer under the signal , the middle two are ground and power planes , the ground and power planes in the middle. Industrial motherboard is more than 6 layers PCB circuit board design, which is designed to strengthen the board anti-electromagnetic interference , electromagnetic compatibility, enhance the stability of the motherboard , and so on .
cpu: industrial motherboard is generally used in low power cpu, in order to adapt to the harsh environment industrial industry applications atomn230 \ 270 \ 330 \ n450d525 part of the north and south bridge functions integrated on the processor cpu.. Different anti-electromagnetic interference capability : the ability to require higher against electromagnetic interference , through emi, emc , such as testing and certification . This requires consideration of two aspects , one is considered from the motherboard circuit layout design, the second is to consider from the choice of materials and structures , power, ground situation .
Support more interfaces: while supporting mini pci-e, pc 104 +, multi com port interfaces , embedded gpio bus, dual display function with lvds, hdmi, dvi interface card with the audience with a more scalable backplane support multiple isa, pci, minipci expansion. Use of the environment : industrial motherboard often in harsh environments operating temperature range up to -20 degrees to 70 degrees ( permanently switched lifetime , bad weather , moisture, vibration , dust , radiation, temperature , etc. ) , and under these circumstances is commercial motherboard can not do the job. Protection: industrial motherboard through a specially designed , in the face of crashes and other anomalies .
