Uses of Conductive Foams

Due to manufacturing tolerances or thermal warping, air gaps in assemblies or between features may exist; conductive foams can be used to fill these spaces and electrically couple surfaces. Filling gaps with conductive foam provides EMI shielding, dust sealing, and creates a protective environment for vulnerable electronics.

Differences in electric potential between two bodies can cause static and electro-magnetic fields to form, resulting in short circuits and interference. Conductive foams with low surface resistivity are effective at mitigating these hazards and preventing failure.

Because Conductive Foam is made of sealing material, it has long-lasting resilience, making it a reliable ground for a PCB or circuit. If an enclosure or assembly must be accessed, the foam returns to its original height without relaxing.

Other applications for conductive foam include the replacement of grounding straps, connectors, and copper clips. Where vibration and shock from a drop may break electrical contact between features, conductive foam is a good choice.

Because of its low firmness and compressibility, this conductive foam can be used without causing strain in even the most delicate assemblies, such as an LCD.
