Fingerstock Gaskets
Tech Etch supplies many custom designed shielding components for special applications from high volume requirements using progressive dies, to prototype and small quantities utilizing photoetch fabrication.
EMI/RFI Shielding Products are designed to either keep out or keep in electromagnetic interference. Shielding reflects and absorbs incident radiation. The higher the attenuation of the shielding, the more effective it is at keeping in or out the undesired electromagnetic interference.
The RoHS-compliant shielding strips are available in lengths of 16” to 24”, in continuous coils of up to 35 feet, as individual fingers, or cut to customized full-finger lengths.
The uncompressed standard finger stocks range from .03” to .44”. These can fill gaps that are as small as .01”. Most of these products are available in two thicknesses to meet your specific requirements.
