Antistatische Oplossingen




Antistatic:
This can mean a wide variety of things, and is deprecated by the writers of 61340-5-1. although the term is widely used, it is better to avoid it if possible.

ESD:
Electro Static Discharge. When the electric field strength in air becomes sufficiently high, its insulating properties break down and charge can flow away in a rapid discharge. ESD can have very short duration high current levels and an cause ignition of flammable materials or damage to electronic components.

ESDS:
Electro Static Discharge Sensitive device. An electronic component that could be damaged by ESD.

Field work:
Handling of ESDS within a temporary EPA, for example at the customer's site.

EPA:
ESD Protected Area. An area in which static electricity is kept below levels that could cause damage to electronic components handled within the area.

Intimate packaging:
Packaging that makes contact with ESDS, for example the inner surface of an ESD protective bag.

Proximity packaging:
Material not making contact with ESDS but which is used to enclose one or more devices. For example the outer surface of an ESD protective bag, or ESD packaging used to contain ESDS already within other packaging.

Secondary packaging:
Material used primarily to give additional physical protection to the outside of a proximity package. E.g. cardboard boxes, padded bags, polythene wrap.

Low charging:
Packaging exhibiting properties which minimises any charge generation.

Conductive:
The word "conductive" has a range of meanings within the context of different standards and should be treated with care. 
Any material that conducts electricity, that is not an insulator
Within the 61340-5-1 standard, "electrostatic conductive" packaging material has surface resistance between 102W and 105W
"conductive" has no specific meanings for other materials or equipment under 61340-5-1 although it is often generally used to indicate materials having resistance values < 106W specific meanings for other equipment are possible, e.g. "conductive footwear" 

Dissipative:
he word "dissipative" has a range of meanings within the context of different standards and should be treated with care. 
Within the 61340-5-1standard, "electrostatic dissipative" packaging material has surface resistance between 105W and 1011W
"dissipative" has no specific meanings for other materials or equipment under 61340-5-1 although it is often generally used to indicate materials having resistance values < 1012W and > < 106W specific meanings for other equipment are possible, e.g. "conductive footwear"

Electrostatic discharge shielding packaging:
Packaging, barrier or enclosure that limits the passage of ESD current and attenuates the energy resulting from an electrostatic discharge such that the maximum energy from 1 000 V HBM ESD applied to the outside of the packaging is less than or equal to 50 nJ measured inside the packaging.

Surface resistance:
This is the resistance of a surface measured by a concentric ring electrode test method defined in 61340-5-1and IEC 61340-2-3: 2000. It is NOT the same as "surface resistively" and is typically about a factor of 10 less than surface resistively as measured in the old EN100015 method.

Point-to-point resistance:
The is the resistance measured between two electrodes placed on a surface, defined in  61340-5-1, IEC 61340-2-3: 2000 and ESD S11.11- 2001

Resistance-to-ground:
This is the electrical resistance measured from a point to the ESD facility electrical earth (usually mains power earth).
