About anti-static mat - negative ion generator
What is the role of anti-static mats? Why should the anti-static mat be grounded?
When handling electrostatic sensitive components, anti-static mats made of anti-static materials should be placed on the workbench so that all SSD terminals, tools, appliances, meters, and human bodies that come into contact with them reach a substantially uniform potential. Static electricity is quickly discharged through the grounding wire on the mat. The anti-static mat should be cleaned regularly to ensure anti-static effect.
What is the principle and function of the negative ion generator? What is the effective range?
1. The negative ion generator generates high voltage electricity and is applied to the discharge needle inside the instrument to ionize the air to generate positive and negative ions. When a large amount of positive and negative ions are blown to the surface of the charged object by the fan, the surface of the object attracts the opposite pole. The ions, which are accumulated on the surface of the product or equipment, are thus neutralized and eliminated.
2. The effective range of the negative ion generator used in the company is: the area of the instrument centered on the radius of 50cm.
What is the difference between anti-static ground wire and wire ground wire and power ground wire?
The role of the anti-static ground wire is to provide a ground leakage path to the static charge that may be generated to prevent the accumulation of local static charges. The line ground wire and power ground wire are used for grounding 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 ESD protection system, damage to the ESD sensitive components is caused. Therefore, the anti-static ground wire should be pulled separately from the ground wire and the power ground. There is also an open circuit alarm. The anti-static grounding can be grounded in a ring, but not grounded in series.
