Antistatic agents are not suitable for all products
Antistatic agent is a simple, convenient and fast antistatic method. It is added to the surface or inside of the insulating material to reduce its ability to generate static electricity. But there are limits to the use of antistatic agents. E.g:
Antistatic agents can be applied to the floor, carpet, work surface, parts carrier, chair, wall, ceiling, tools, paper, plastic, and skin by brushing, spraying, rolling, dipping, rubbing or other methods. They become ESD-protected objects to varying degrees. Some antistatic agents are also good scavengers, which can be mixed with water to clean surfaces such as floors and worktops, while turning them into antistatic.
However, antistatic agents are not suitable for use on circuit boards, parts, or components because they increase conductivity and may affect solderability. During the cleaning operation, the antistatic agent will be removed, and the cleaned surface may need to be disposed of from scratch. The anti-static supply protection period depends on the resistance of the material such as polyethylene, and then use an electrostatic field meter to monitor the potential and its decay time, or use a suitable device to measure the surface resistivity of the material sample. ESD protection materials that need to be disposed of with antistatic agents on time are approximately labeled with dates indicating the ESD protection function of these items should be checked from scratch. These items can include shipping buckets, pallets and protective gloves.
In addition, pay attention to the characteristics to be considered when selecting an antistatic agent. In addition to its antistatic properties, it also includes: prohibiting the growth of bacteria; non-toxic; non-corrosive; non-irritating to humans.
