How to minimize the amount of static electricity
1. First, define the scope of electrostatic sensitive area; in this area, the company's electrostatic control procedures must be followed and implemented. This includes not carrying unnecessary static electricity generating materials to this area, such as general plastic products and polystyrene foam.
The best way to reduce the amount of static electricity is to minimize unnecessary insulating materials in the work area. (Insulating materials cannot conduct electricity. It is a source of high static electricity and is prone to static electricity.
2. In order to prevent the generation of static electricity and electrostatic field, the work area must take appropriate protective measures, such as conductive floor, conductive wax, etc.; personnel must wear static shoes with static dissipative material soles and wear anti-static clothing. Especially the plastic parts on metal tools are not allowed in the static protection zone. Soldering irons, tin suction devices, test equipment, etc. must be designed with special and safe anti-static design; and unapproved equipment must not be brought into the protected area.
3. Secondly, avoid loose and hanging clothing accessories from touching sensitive components-keep the electrostatic sensitive components and clothing at least 6 inches (15 cm) away.
4. A common misunderstanding is that high humidity can solve the problem of static electricity, so there is no need to consider other methods to reduce the generation of static electricity. In fact, it is incorrect. Although high humidity can reduce the static electricity generated by the human body, it is still enough to damage sensitive components. The correct concept is that high humidity can suppress the amount of static electricity, while low humidity is the opposite.
5. At any time, pay attention to the static electricity safety protection area signs in the working environment. If you enter these areas, you should follow the electrostatic protection procedures established by the company, including isolating all persons or objects that may generate static electricity outside the protected area.
In addition, check and confirm that all sensitive components passing through the electrostatic protection area are equipped with appropriate and obvious electrostatic protection labels; however, components that are not marked should not be regarded as electrostatic safety objects.
6. Although it is possible to judge which devices are electrostatic sensitive, it is a good working habit to treat all electronic components and assembly actions as electrostatic sensitive. It is easier to maintain rigorous electrostatic protection work for all the components you handle and treat them as daily habitual tasks than to handle differently depending on the nature of individual components.
