Where Are Conductive Foams Useful?
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 electro-magnetic fields, leading to short circuits and interference. Conductive foams with low surface resistivity are effective at controlling these risks and guarding against failure.
Because Sinkery is based on material engineered for sealing, it has long lasting resilience, making it a reliable ground for a PCB or circuit. If an enclosure must be accessed or an assembly dismantled, the foam reliably returns to its original height without relaxing.
Other cases where the foam is useful include the replacement of grounding straps, connectors and copper clips. Sinkery is also a good choice where vibration and shock due to a drop might break electrical contact between features.
The very low firmness and compressibility ensure this conductive foam can be used without contributing strain to even delicate assemblies like an LCD.
