What is The antistatic EVA
Views: 1596 Feb 24 , 2018
The antistatic EVA is closed-cell foam. In the forming process of EVA foam, conductive carbon powder filler is added and molded and foamed to form the EVA foam.
Characteristics
1. excellent anti-static performance: anti-static timeliness for permanent anti - static, not affected by environmental dry humidity; 2. excellent cushioning performance: independent and fine closed cells; 3. excellent conductivity: electrostatic index value 104 -...

What hazards can the electrostatic discharge ESD cause?
Views: 1420 Jan 31 , 2018
ESD
electrostatic discharge (ESD), the biggest and most common hazard is in the
electronics industry, and all high precision technology industries based on
electronic devices. Static electricity can inadvertently expensive electronic
device breakdown, the damage caused by dysfunction of electronics and
components, especially semiconductor integrated components now increasingly
large scale, integrated voltage is lower and lower, the greater the...

What is ESD?
Views: 1356 Jan 26 , 2018
Electrostatic Discharge is a high
voltage event from the release of electrical energy caused by static
electricity or electrostatic induction. ESD can cause permanent damage to
electronics and integrated circuits.

Two Causes of ESD
Views: 1521 Jan 25 , 2018
Static
electricity is One of the causes of ESD events. Static electricity is
often generated through tribocharging, the separation of electric charges that
occurs when two materials are brought into contact and then separated. Examples
of tribocharging include walking on a rug, rubbing a plastic comb against dry
hair, rubbing a balloon against a sweater, ascending from a fabric car seat, or
removing some types of plastic packaging. In all...

What is Electrostatic discharge?
Views: 1518 Jan 24 , 2018
Electrostatic
discharge, which
shorted for ESD, is the sudden flow of electricity between two
electrically charged objects caused by contact, an electrical short, or
dielectric breakdown. A buildup of static electricity can be caused by
tribocharging or by electrostatic induction. The ESD occurs when
differently-charged objects are brought close together or when the dielectric
between them breaks down, often creating a visible...

How to prevent ESD damage in electronics
Views: 1471 Jan 22 , 2018
Prevention
of ESD bases on Electrostatic Protective Area (EPA). EPA can be a small working
station or a large manufacturing area. The main principle of an EPA is that
there are no highly charging materials in the vicinity of ESD sensitive
electronics, all conductive materials are grounded, workers are grounded, and
charge build-up on ESD sensitive electronics is prevented. International
standards are used to define typical EPA and can be found for...

Views: 1406 Jan 16 , 2018
1. Bare populated boards with no battery. Single-use: Anti-static (pink)
inside of a silver conductive bag. Multi-use: Conductive (black) foam.
Alternately you can use static dissipative (black) foam inside of a conductive
container/faraday cage.
2. Battery cells: Single-use: Anti-static (pink) inside of a silver
conductive bag. Multi-use: Static dissipative (black) foam inside...

Where Are Conductive Foams Useful?
Views: 1466 Jan 11 , 2018
Air gaps in assemblies or between features may exist due to manufacturing tolerances or thermal warping; conductive foam can be used to fills these spaces and electrically couple surfaces. Using a conductive foam to fill gaps provides EMIshielding, dust sealing and forms a protective environment for susceptible electronics.
Differences in electric potential between two bodies can result in the build-up of static and...

Surface Resistivity & Surface Resistance
Views: 1700 Nov 28 , 2017
Do you know the
difference between surface resistivity and surface resistance? Although there
has been a lot of discussion centered around these parameters, they are
probably some of the least understood in the ESD industry. ESD practitioners
need to have a clear understanding of what the differences are to make informed
material selections in their work environments.
Let’s start with the
basics. Surface resistivity in ohms/square is used...
