How do we use conductive foams and what benefits are there for ESD prevention?
These foams are used to protect ESDS devices and are typically made up of polyurethane and polyethylene. By inserting an integrated circuit into the foam we nsure that all pins are short circuited to the same potential value. Also these foams provide a mechanical cushioning effect which helps to add protection for the pins so they do not get bent or bumped during transport or handling. They can be purchased in sheets of different sizes and thicknesses, their surface and volume resistivity are in the order of 1KΩ to 100KΩ.
