How to do effective static control?

Although the technology, processes and materials have different variations at different times , but the design and implementation of effective static control program is still based on the following five concepts:

1, The ESD protection design to internal components and products :Design your components, products and assemblies to make it more reasonable to avoid electrostatic discharge ESD role. Possible, without the use of electrostatic sensitive components , or those you use an electrostatic discharge sensitive components provide adequate ESD input protection . Here is conflicting , advanced production technology means more compact and more complex geometries, often more sensitive to ESD. However , the more established static control during the production design , fewer problems occur thereafter .

2 , Materials and processes to eliminate static electricity generated Obviously, the product design is not the complete answer . You can not escape the ESD components and products , but you can reduce or eliminate the generation and accumulation of electrostatic discharge . First, from the working environment as possible to reduce or eliminate static electricity generated in many processes or materials , such as ordinary plastic . ESD does not occur because of the same electric potential between the holding or zero potential material, the step of working environment or materials should be kept at the same electrostatic potential. Typically, these materials should be electrically conductive or electrically connected to disperse to the same common ground , such as an electrical ground . In addition , to provide static wristbands ground , floor or table surface safely reduce the discharge and accumulation.

3 , Disperse or neutralize electrostatic discharge Because all it is impossible to eliminate static control , so our third principle is to safely disperse or neutralize those electrostatic discharge to occur . Proper grounding and electrical conductivity of the material or disperse plays a major role . For example , workers with static electricity into the working environment can be worn with a wrist strap or ESD control work shoes stepped on ESD floor mat to eliminate static electricity themselves . Static spread ground , rather than the discharge sensitive components . For some objects, such as plastics and other insulators common ground can not eliminate electrostatic discharge. Typically , the use and discharge of ions to the insulating material. Positive and negative ions generated during attracted to the discharge surface, thereby effectively and electrostatic discharge .

4, to provide physical protection of ESD Our fourth principle is to prevent the occurrence of electrostatic discharge to come into contact with sensitive components and assemblies . One way is that for components and assemblies to provide proper grounding or diversion, so that any discharge from the product dispersed. The second method is suitable for the packaging and transport of packaging material sensitive components . These materials can be effectively shielded from static products , reduce static electricity due to the movement within the packaging of any product produced .

5 , test your process and environment The use of field strength meter to detect whether there exist potential hazards ESD electrostatic field . Measurement is the most secure method. Identify and quantify regional ESD protection to those in genuine need , allowing you to focus on those areas of most concern . In addition, you can confirm that the region does not produce ESD hazards , save money you make those unnecessary protection .This became the basis of five principles of effective static control program. They can help select the appropriate materials and procedures used to effectively control the ESD. In most cases, the effective procedure involves all of these concepts . In the development of control programs , identify those sensitive components , sensitive level , and those who operate them with ESD hazards. Then look at the concept of the protection to which these components .
