What is the principle of a clean room?
A clean room is, in fact, a clean room in which you will not find particles. The less dust you find in the blank, the more qualitative it is and the better a hard drive will be repaired for example.
To be up to standards this room must have the ISO 14644-1 standard, which corresponds to an ISO 8 room, which indicates that there will be no more than 29,300 particles of 5 µm / m³, which is really weak.
When working in this type of room, the person must also be protected and well equipped. The dust level is therefore controlled, as well as the humidity level, as well as the temperature.

Once fully equipped, the technician carefully opens the hard drive, after which the magnetic plate, where the information storage elements are located, is removed. But these are not the only elements to be removed, there is also the reader head, the electronic board of the disc (PCB), once removed they are examined.
If, at the time of dismantling, the technician notices any deterioration of the equipment, or the need to change parts, he will order them to make the necessary repairs.
