1. Chassis
The chassis of the industrial computer has a power supply, a passive base plate, an electric fan, etc. Power supply: It is for long-hour uninterrupted operation, so the performance is better, it should be noted that the dust entry is reduced as much as possible, so as not to affect the operation of the fan. In addition, it should also be anti-static and lightning protection.
Passive baseboard: It provides power for various boards, and requires: it cannot be used to dial the plug-in board when the baseplate is energized; Do not use too much force when inserting the paddle card; Avoid scratching the bottom plate when cleaning the bottom plate.
Electric fan: The fan of the industrial computer blows air into the chassis to lower the temperature in the chassis. Requirements: The filter on the outside of the fan should be cleaned on time to prevent excessive dust from entering the chassis.
In addition, dust should not accumulate in the slot of the industrial computer, otherwise it will lead to poor contact and even short circuit. Whether the metal feet in the slot are aligned and whether they are bent, otherwise it will affect the operation of the board in the system, and various phenomena such as the industrial computer will not be displayed when the computer is turned on, the board cannot be found, and the machine will crash.
2. Hard disks, optical drives, and floppy drives
Hard disk: Do not disassemble the hard disk of the industrial computer at will, avoid oscillation and kneading. Try not to turn off the power of the computer when the hard disk is running, so that the sudden shutdown will cause the hard disk track to be damaged and the data will be lost. When handling the industrial computer, it must be packed in an antistatic plastic bag or fixed with a sponge and other shockproof pressure materials, and the virus must be checked often to prevent corrosion.
Optical drive: The optical drive of the industrial computer should not vibrate, distort or knock during use.
Floppy drives: Do not use defective and moldy floppy disks to prevent scratching the head. When the floppy drive is reading and writing to the disk (the floppy drive indicator light is on), do not force the disk to take out the disk, so as to prevent the head from being damaged or offset, resulting in the failure to read and write normally.
3. Motherboard
The motherboard of the industrial computer is designed for long-term operation in a chaotic environment, and the requirements are: no live plugging (memory module, mouse behind the board, keyboard, etc.), live plugging will cause damage to the jack. The jumper on the IPC motherboard can not jump at will, you should check the manual or user manual, otherwise it will be damaged due to the different voltage settings of different types of motherboards.
The dust of the industrial computer motherboard should be cleaned on time, not with alcohol or water, and the dust should be sucked or blown off with a dry brush, vacuum cleaner or Pishanjun. Keep the memory slots on the motherboard clean and free of broken or crooked feet. The gold finger pierced into the passive baseplate under the motherboard should be clean, and it should be plugged in tightly and in place on the baseboard.
4. Various boards (graphics card, sound card, network card, etc.)
The board card of the industrial computer should pay attention to dustproof, the plug pins should be intact, the board should not be distorted vertically, and the connectors on the external jack of the board should not be plugged in live.

External factors that lead to the failure of industrial computers - EVOC
The ambient humidity is not suitable. The industrial computer is mainly composed of integrated circuits of many electronic components, and its insulation function is greatly related to the ambient humidity. If the humidity is too high, it is easy to form a short circuit and burn the circuit board; If the humidity is too small, it is easy to generate static electricity, and it will also break down some electronic components.
