English/Spanish (4” x 10”) ESD Area Warning Sign.
- Indicates the presence of an established ESD Protected Area to personnel prior to entry into the Protected Area. English on one side, Spanish on other.
- High Impact PVC Material with 1/2” x 5” Double-Sided Adhesive Included.
- Easy to install and designed for long term use in an electronics production environment.
- Made in the United States of America.
Regarding Principles of ESD Control – ESD Control Program Development, and Basic Principles of Static Control We suggested focusing on just six basic principles in the development and implementation of effective ESD control programs:
- Design in protection by designing products and assemblies to be as robust as reasonable from the effects of ESD.
- Define the level of control needed in your environment.
- Identify and define the electrostatic protected areas (EPAs), the areas in which you will be handling ESD sensitive parts (ESDS).
- Reduce Electrostatic charge generation by reducing and eliminating static generating processes, keeping processes and materials at the same electrostatic potential, and by providing appropriate ground paths to reduce charge generation and accumulation.
- Dissipate and neutralize by grounding, ionization, and the use of conductive and dissipative static control materials.
- Protect products from ESD with proper grounding or shunting and the use of static control packaging and material handling products.
Identifying the Problem Areas and the Level of Control - One of the first questions we need to answer is “How ESD sensitive are the parts and assemblies we are manufacturing or handling?” This information will guide you in determining the various procedures and materials required to control ESD in your environment. How do you determine the sensitivity of your parts and assemblies or where can you get information about their ESD classification or withstand voltage?
A first source would be the manufacturer or supplier of the component itself or the part data sheet. It is critical that you obtain both Human Body Model (HBM) and Charged Device Model (CDM) ratings. You may find that you need to have your specific device tested for ESD sensitivity. However, be aware that the correlation between voltages used for device qualification and static voltages measured in the field is weak.
A key question to answer for your facility: “Which areas of our facility need ESD protection?” This will allow you to define your specific electrostatic protected areas (EPAs), the areas in which you will be handling sensitive parts and the areas in which you will need to implement the ESD control principles. Often you will find that there are more areas that require protection than you originally thought, usually wherever ESDS devices are handled.
