Guidelines how to set up an ESD Protected Area (EPA)


Preface

  • Implementing ESD safe materials and products should be performed according a specific logical ESD strategy.
    Without these specific ESD procedures it has little to no sense to install ESD safe products.
  • Therefore we recommend to perform a pre audit described in the ESD plan of approach, on the next pages.
  • This ESD plan of approach, must be based on recent recordings of the company, an overview of the measures to be taken in the field of protection against static electricity, as well as the facilities have to be taken in this context.
    A distinction is made between the necessary, preferably directly implementing provisions and recommended facilities that can be realized on longer terms.

Commonly used terms

  • ESD = Electro Static Discharge (ESD)
  • ESDS = Electro Static Discharge Sensitive (sensitive to static discharges)
  • EPA = ESD Protected Area (ESD-safe area)
  • Fc = Faraday cage
  • Pink Poly = plastic film products with a non-rechargeable (pink) coating (antistatic)
  • Shielding = packaging materials with a metallized (conductive) layer: These materials thus have a Faraday cage function.

First step: Drafting your ESD procedure

First it should be clearly defined which zones are EPA and which are not. Access to these areas can only be provided to those who are aware and comply with the preventive prescribed measures.
This requirement applies to everyone, private operators, management, temporary employees, subcontract, maintenance personnel, visitors, ...

Of general interest: correctly adjusting the relative humidity.
 


Second step: General measures


1. All areas where ESD safe work is being performed should preferably be marked as such; using special ESD warning shields or stickers and / or floor marking tape, the EPA’s can clearly be marked.
Demarcation and defining the EPA (ESD Protected Area) all this to keep out and end off misunderstandings and unauthorized in these critical area(s) where ESD safe should be worked.

2. For controlling wrist strap, grounding cables, ESD shoes or heelgrounders, it is necessary to provide and install a wrist-band/shoe-test station, in a prominent place, preferably at the entrance to the EPA. 
Also the wristbands and grounding cables of the field service kits from any field staff can be checked here. It is recommended that the staff fill in each check, with date and initials, on the checklist hanging next to the tester.

2.a. Access control: before entering the EPA wristbands, grounding cables and footwear always should be checked. Possible access may or may not be linked to an ESD Access System.

3. Footwear: The same principle applies to us humans. We want to enter the EPA we need to check our ESD safe shoes The range is very extensive and we make a distinction between ESD safe and ESD-safe safety shoes. When working ESD safe, consistently checking is really required, this is why you have to check your footwear and wristbands daily before entering the EPA.

4. Wearing ESD clothing is strongly recommended so charges accumulated by motion, and therefore friction of our normal clothes, can be shielded from the sensitive components.

Why ESD clothing is so important? (watch video)

5. ESD safe Workbenches provided by BASS-ESDproducts.  All of these tables are to be connected via a resistor of 1 MOhm coupled to ground/earth.

6. Grounding / grounding: The ESD standard IEC 61340-5-1/5-2 says that when one is performing his job sitting a wrist strap to ground always need to be worn. It is obvious that we also have to connect our workbenches and shelves to earth. We do this with grounding plugs and grounding cables (these are included in the table).

7. Tools: Certainly not unimportant because with this tool one comes closest to the ESD sensitive components, so it is strongly recommended to use ESD safe tools.

8. ESD Chairs: Here you have a wide choice from our collections that give us the assurance and guarantee that the seats are really ESD safe.

9. Trolley's: For transporting goods within the EPA, it is important they don't generate static charge caused by friction of the wheels.

10. All ESDS components and printed circuit boards should be stored throughout the company and transported in an ESD-safe packaging with Cage of Faraday function;
this may be in the type of a static shielding bag or a container of conductive plastic. The shielding bags can be sealed with. ESD with special warning stickers.

11. Pink poly products, such as the rose packing bags and bubble foil, are not rechargeable (antistatic).
These products however have not KvF function and are intended primarily as a non-rechargeable or disposable packaging for temporary use only used in the EPA.
The anti-static coating in the plastic evaporated namely, under the influence of UV light, after a period of time, and loses its effect (the typical pink color is in this case becomes more pale).

12. The first and most important step in ESD safe working is to make sure that there are NO static materials in the EPA are present.
The use of static rechargeable (packaging) materials, coffee cups, plastic folders, trash bags, etc., in an EPA should be avoided whenever possible.

13. To ensure an adequate internal control it is strongly recommended to provide the ESD coordinator within the company off a surface resistivity meter and an electrostatic field meter.

14. Floor: This is provided and should conform to EN / IEC 61340.
In case of optimization at standing work ESD anti-stress mats can be offered.
The maintenance of an ESD floor should be done with appropriate detergent aims to prevent the floor to become insulation by using ordinary cleaning agents.

15. Warehousing and stock must be stored in proper packaging and custom carrying racks or cabinets.
The packaging of ESD sensitive components must be done in the right packaging Pink bags do not protect against static charges and may only be used within the EPA.
Sensitive components  (without housing) which will transported outside the EPA should be put in Shielding bags or Moisture barrier bags (if they are susceptible to oxidation).

16. ESD Cleaning & maintenance: The installation of an ESD Protected Area (EPA) is very important and requires expertise.
Even more important, and all too often overlooked, is the maintenance of these ESD protected areas. ESD conductive (dissipative surfaces), floor as well as table,
should be treated with appropriate ESD-cleaners and cleaning utilities to assure these conductive properties are preserved.
The use of ESD vacuum cleaners according the ESD Standards is of utmost importance not want to cause damage to ESD sensitive components within the EPA.

17. In addition taking the necessary ESD measures, it is important that all personnel, directly or indirectly, in contact with ESDS products is well aware of the phenomenon of ESD. B.A.S.S. ESDproducts provides special ESD courses and training which explains and shows the dangers of dealing with electrostatic charges, how you can recognize and protect ESDS devices getting damaged by ESD.
