ESD plastic: protecting electronics from static discharge
We work daily with plastics in different applications, but sometimes we forget about the small details that can make a big difference. One such detail is static discharge, which can be devastating for sensitive electronics. Here we will take a closer look at ESD plastics and how they can protect our electronics.
But first, what is static discharge? It is the charge that forms when two materials come into contact with each other and then separate. This can happen when we handle plastics, textiles or other materials that can generate static electricity. And the question is, can we protect our electronics from this type of damage?
Static dissipative vs conductive
When it comes to ESD plastics, there are two main types: static dissipative and conductive. The big question is, what is the difference between these two types? Well, static dissipative plastics have a surface resistance that lies between 10^4 and 10^11 ohm, while conductive plastics have a surface resistance that is lower than 10^4 ohm. This means that static dissipative plastics can divert static electricity more slowly, while conductive plastics can divert it more quickly.
For example, if we have a static dissipative plastic such as PE-ESD, it can have a surface resistance of 10^6 ohm. This means that it can divert static electricity, but not as quickly as a conductive plastic such as PA-ESD, which can have a surface resistance of 10^3 ohm.
Common ESD materials
When it comes to ESD materials, there are several common types used in electronics manufacturing and clean rooms. One of the most common is POM-ESD, which is a type of polyoxymethylene that is modified to be static dissipative. Another common type is PE-ESD, which is a type of polyethylene that is modified to be static dissipative.
We also offer PA-ESD, which is a type of polyamide that is modified to be conductive. These materials are all designed to protect electronics from static discharge, but they have different properties and areas of use.
Test methods
When it comes to testing ESD plastics, there are several methods that can be used. One of the most common methods is to measure the surface resistance using a resistivity meter. This gives us an indication of the material's ability to divert static electricity.
Another method is to use a static generator to simulate static discharge. This can give us a better understanding of the material's behavior under real conditions.
Applications in electronics manufacturing and clean rooms
When it comes to applications in electronics manufacturing and clean rooms, ESD plastics are of great importance. They can be used to protect sensitive electronics from static discharge, which can destroy components and cause expensive repairs.
For example, in a clean room environment, ESD plastics can be used to manufacture tools and equipment that handle sensitive electronics. This can help to minimize the risk of static discharge and protect the sensitive equipment.
But why do standard plastics generate static electricity? Well, it is because they often have a low surface resistance, which makes it easy for static electricity to form. Additionally, standard plastics can often be more prone to generating static electricity when they are exposed to friction or other forms of mechanical stress.
If we want to protect our electronics from static discharge, what should we do? Should we use standard plastics and risk destroying our equipment, or should we invest in ESD plastics that can protect our electronics?
