Anti-static measures
In the computer production workshop, the floor is anti-static, the manufacturing equipment is anti-static, the testing instrument is anti-static, the chip turnover box and the warehouse are anti-static, even the operator must wear anti-static clothing and wear anti-static clothing. Electrostatic gloves, a faction of fully armed appearance. However, in the process of computer application, ESD will still be used. In order to avoid the harm of induced static electricity, the whole machine needs to be shielded and grounded.
The metal case of a computer is an important measure for shielding static electricity. A good grounding can greatly reduce the probability of being harmed by static electricity. The motherboard, interface card, floppy drive, hard drive, optical drive and other equipment in the chassis, as well as the metal shielding net wrapped around the signal line, are connected to the whole through the chassis, and then connected to the earth through the power ground wire, which can not only eliminate the external The induced static electricity can also eliminate the friction static electricity generated by the rotating equipment itself. In order to ensure good contact between the components, various elastic contacts or elastic contact pieces are arranged on the chassis.
