Protective requirements for anti-static tweezers, etc.
Anti-static brushes, screw drivers, anti-static tweezers, splitter bars and other operating tools, as well as station holders are preferably made of static dissipative materials. It is not advisable to use metal materials directly. If it is necessary to use a metal material to make the tool, in order to prevent the metal appliance from being discharged when the electrostatic discharge sensitive device is charged or the metal appliance is poorly grounded, the ion current static eliminator should be considered.
The anti-static brush and the resistance between the end points of the outer surface of the station frame are less than 10 9 ohms. In addition, 90% of the static electricity (positive and negative 1000-plus plus 100V) time is greater than 2S before use.
The point-to-point resistance of antistatic curtains and sticky mats (rags) should be in the range of 10 to the power of 10 to 10 ohms. Static decay (plus or minus 1000 - plus or minus 100V) time is greater than 2S before use.
