Hoʻokumu ʻia ka lipine alumini alumini conductive me ka pepa alumini a hoʻokuʻu i ka pepa i uhi ʻia me ka conductive acrylic pressure-sensitive adhesive ma kekahi ʻaoʻao. Hoʻopili ʻia ke kūlana paʻa i ka uila a pani ʻia ke āpau, a ʻo kāna hopena pale EMI ka mea maikaʻi loa.

Wahi a kona conductivity uila, ua māhele ʻia nā lipine alumini alumini i ʻelua mau ʻano: ʻelua-conducting alumini a me hoʻokahi-conducting. ʻO ka pahu alumini ka mea metala a loaʻa iā ia ka conductivity uila. Hoʻohana ke alakaʻi pālua i ke kolu conductive e like me ke kāpili hope e hana i kahi hopena conductive ʻaoʻao ʻelua; ma ka ʻaoʻao ʻē aʻe, hoʻohana ke alakaʻi hoʻokahi i ke kāpili non-conductive, a ʻo ka ʻaoʻao wale nō i loko o ka pahu alumini ka conductive. ʻO kāna hana ʻo ia ka hoʻopau ʻana i ka interference electromagnetic, hoʻokaʻawale i ka pōʻino o nā hawewe electromagnetic i ke kino o ke kanaka, a pale i ka uila pono ʻole a me ka wā e pili ana i nā hana huahana.
