EMI Shielding EMI Shielding Wolukidwa Layer ndi Intertwining Bare kapena Tinned Copper Waya
Mafotokozedwe Akatundu
Phokoso lamagetsi ndi mtundu wa mphamvu yamagetsi yotayikira ndi zida zamagetsi monga zotsukira, ma jenereta, ma transfoma, zowongolera zolumikizirana, zingwe zamagetsi ndi zina. Imatha kuyenda kudzera mu mizere yamagetsi ndi zingwe zama siginecha, kapena kuwuluka mlengalenga ngati mafunde amagetsi omwe amachititsa kulephera komanso kuwonongeka kwa magwiridwe antchito. .
Kuti muteteze ntchito yoyenera ya chipangizo chamagetsi, kusamala kumayenera kuchitidwa paphokoso losafunikira.Njira zazikuluzikulu ndi (1) kuteteza, (2) kusinkhasinkha, (3) kuyamwa, (4) kudutsa.
Kungoyang'ana kwa kondakitala, chishango chosanjikiza chomwe nthawi zambiri chimazungulira ma conductor onyamula mphamvu, chimakhala chowonetsera ma radiation a EMI komanso nthawi yomweyo, ngati njira yopangira phokoso pansi.Choncho, popeza kuchuluka kwa mphamvu zomwe zimafika kwa woyendetsa wamkati zimachepetsedwa ndi chingwe chotchinga, chikokacho chikhoza kuchepetsedwa kwambiri, ngati sichikutha.The attenuation factor imadalira mphamvu ya chitetezo.Zowonadi, magawo osiyanasiyana oteteza amatha kusankhidwa pokhudzana ndi kuchuluka kwa phokoso lomwe lilipo m'chilengedwe, m'mimba mwake, kusinthasintha ndi zinthu zina zofunika.
Pali njira ziwiri zopangira zosanjikiza bwino zotchingira ma conductor.Yoyamba ndi kugwiritsa ntchito nsalu yopyapyala yopyapyala ya aluminiyamu yomwe imazungulira makondakitala ndipo yachiwiri kudzera pansanjika yoluka.Mwa kulumikiza mawaya opanda kanthu kapena amkuwa, ndizotheka kupanga wosanjikiza wosinthika mozungulira ma conductor.Yankho limeneli limapereka ubwino wosavuta kuyika pansi, pamene chingwecho chatsekedwa ndi cholumikizira.Komabe, popeza kuluka kumapereka mipata yaying'ono ya mpweya pakati pa mawaya amkuwa, sikumapereka kuphimba kwathunthu.Kutengera kulimba kwa kuluka, nthawi zambiri zishango zolukidwa zimateteza ku 70% mpaka 95%.Chingwe chikayima, 70% nthawi zambiri imakhala yokwanira.Kuphimba pamwamba sikungabweretse chitetezo chokwanira.Popeza mkuwa umakhala ndi ma conductivity apamwamba kuposa aluminiyamu ndipo chomangira chimakhala ndi zochulukira zopangira phokoso, kuluka kumakhala kothandiza kwambiri ngati chishango poyerekeza ndi chojambulacho.
