The role of anti-static table mat
When operating static-sensitive components, an anti-static table mat made of anti-static materials should be laid on the workbench, so that all SSD terminals, tools, appliances, meters, and human bodies in contact with it reach a basically uniform potential, and The static electricity is quickly discharged through the grounding wire on the table mat. The anti-static table mat should be cleaned regularly to ensure the anti-static effect.
What is the principle and function of negative ion generator? What is its effective range?
1. The negative ion generator generates positive and negative ions by generating high voltage and applying it to the discharge needle inside the instrument to ionize the air. When a large number of positive and negative ions are blown to the surface of a charged object by a fan, the surface of the object attracts the opposite pole Sexual ions, the static electricity accumulated on the surface of the product or equipment can therefore be neutralized and eliminated.
2. The effective range of the negative ion generator currently used in the company is: centered on the instrument, with a radius of 50cm.
What is the difference between the anti-static ground wire, the wire body ground wire, and the power ground wire?
The function of the anti-static ground wire is to provide a leakage path for the electrostatic charge that may be generated to prevent the accumulation of local electrostatic charge. The wire body ground wire and the power ground wire are used for the grounding of instruments and equipment to protect personal safety, protect equipment and facilities, reduce electrical noise and improve equipment operation quality. In order to prevent lightning current and fault current from flowing into the electrostatic protection system and causing damage to ESD sensitive components, the anti-static ground wire must be pulled separately from the body ground wire and the power ground wire. And there is an open circuit alarm. Anti-static grounding can be ring grounding, but not series grounding.
