Where Are Conductive Foams Useful?
Views: 1737 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: 2008 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...

What is conductive foam?
Views: 13237 Nov 23 , 2017
Conductive foam is similar to standard packaging foams but with
one crucial difference – the addition of carbon to the polymer mix during the
manufacturing process to provide a high level of conductivity. This allows any electric current to pass through the cell
structure of the foam and away from the component. Generally, the foam will have permanent conductive performance,
meaning it is ideal for multi-trip...

The Causes of ESD Effect

The Causes of ESD Effect
Electrostatic
discharge (ESD) is the
sudden flow of electricity between two
electrically charged objects caused by contact, an electrical short, or dielectric breakdown.
One of the causes of
ESD events is static electricity. Static electricity
is often generated through tribocharging,
the separation of electric charges that occurs when two...
