Summary of methods to minimize static electricity
We all know that static electricity cannot be eliminated, so is there any way to reduce the amount of static electricity generated? Below, the ESD technical consultation of the Anti-static Information Network will explain to you from several aspects:
1. First, define the scope of the static sensitive area; in this area, the company's static control procedures must be followed and implemented. This includes not bringing unnecessary static electricity generating materials into this area, such as general plastic products and polystyrene foam.
The best way to reduce the amount of static electricity generated is to reduce the number of unnecessary insulating material objects in the work area as much as possible. (Insulating materials cannot conduct electricity. They are themselves high static electricity generators and carry static electricity and are prone to generate static electricity fields.
2. To prevent the generation of static electricity and static electricity fields, appropriate protective measures must be taken in the work area, such as conductive floors, conductive wax, etc.; personnel must wear static electricity shoes with static electricity dissipating soles and wear anti-static clothing. Touch the wall lightly with your hand, especially the plastic material part of metal tools is not allowed in the static protection area. Soldering irons, desoldering machines, testing equipment, etc. must be specially designed for safety anti-static; and unapproved equipment cannot be brought into the protection area.
3. Secondly, avoid loose and hanging clothing and accessories from touching sensitive components-keep static sensitive components away from clothing 6 inch (15 cm) or more.
4. It is a common misunderstanding that high humidity can solve the problem of static electricity, so there is no need to consider other methods to reduce static electricity generation. In fact, this is incorrect. Although high humidity can reduce the static electricity generated to the point where the human body cannot touch and sense it, it is still enough to damage sensitive components. The correct concept is that high humidity can suppress the amount of static electricity generated, while low humidity is the opposite.
5. Always pay attention to the static safety protection area signs in your work environment. If you enter these areas, you should follow the static protection procedures established by the company, including isolating all people or objects that may generate static electricity outside the protection area. And check and confirm that all sensitive components passing through the static protection area are attached with appropriate and obvious static protection signs; however, do not assume that components without signs are static safety objects.
6. Although it is possible to determine which devices are static sensitive, it is a good working habit to treat all electronic components and assembly actions as static sensitive. It is easier to maintain strict static protection operations for all components you handle and treat them as daily habitual work than to treat them differently according to the nature of individual components.
