Xav paub yog vim li cas tooj liab ntawv ci yog qhov zoo tshaj plaws shielding khoom?

Electromagnetic thiab xov tooj cua zaus cuam tshuam (EMI/RFI) yog ib qho teeb meem loj rau cov ntaub thaiv npog cable sib dhos siv hauv kev xa cov ntaub ntawv. Qhov kev cuam tshuam me tshaj plaws tuaj yeem ua rau lub cuab yeej tsis ua haujlwm, txo cov teeb liab zoo, cov ntaub ntawv poob, lossis kev cuam tshuam tag nrho ntawm kev sib kis. Shielding, uas yog ib txheej ntawm rwb thaiv tsev uas muaj hluav taws xob lub zog thiab yog qhwv ib ncig ntawm ib tug hluav taws xob cable kom nws tsis txhob emitting los yog absorbing EMI / RFI, yog ib feem ntawm shielded cable los ua ke. Txoj kev siv ntau tshaj plaws tiv thaiv kev tiv thaiv, yog "cov ntaub thaiv npog" thiab "braided shielding."

Ib txoj hlua tiv thaiv uas siv cov txheej nyias ntawm tooj liab lossis txhuas rov qab los txhawb kev ua neej ntev yog hu ua ntawv ci. Lub tinned tooj liab ntws hlau thiab ib daim ntaub thaiv npog ua haujlwm ua ke los ua cov ntaub thaiv npog.

Qhov zoo ntawm kev siv tooj liab ua ntawv ci thiab braided shielding

Ob hom nrov tshaj plaws ntawm cov ntaub thaiv npog siv hauv kev lag luam yog cov ntawv ci thiab braided. Ob hom yog siv tooj liab. Ntawv nyiaj shielding muab kev tiv thaiv tiav thiab tiv taus cov ntawv thov RFI siab. Cov ntaub thaiv npog yog ceev, pheej yig, thiab yooj yim los tsim vim nws yog lub teeb yuag thiab pheej yig.

Mesh thiab flat braid shields yog ob qho tib si muaj. Thaum lub sijhawm tsim khoom, lub tiaj tus braid ua los ntawm tinned tooj liab yog dov rau hauv braid. Nws cov qib siab ntawm kev hloov pauv ua rau nws muaj kev tiv thaiv zoo heev rau cov hoses thiab tubings. Nws tuaj yeem siv los ua cov hlua khi rau cov khoom siv hauv tsheb, dav hlau, thiab nkoj nrog rau kev tiv thaiv cables, pluaj hauv av, roj teeb hauv av, thiab roj teeb hauv av. Nws yog haum rau txhua daim ntawv thov uas hu rau woven, tinned tooj liab braid thiab kuj tau tshem ntawm ignition cuam tshuam. Yam tsawg kawg ntawm 95% ntawm cov ntaub thaiv npog yog tinned tooj liab. Weaved tinned tooj liab shields ua tau raws li cov cai ntawm ASTM B-33 thiab QQ-W-343 hom S.

Copper foil tapes 'conductive nplaum yog zoo meej rau kev hloov kho cov ntawv luam tawm Circuit Court boards, txhim kho kev ruaj ntseg tswb circuits, thiab nteg tawm thiab tsim cov kab hluav taws xob board prototypes. Nws yog qhov zoo heev rau EMI / RFI shielding cable wrapping thiab ua kom muaj hluav taws xob txuas ntxiv los ntawm kev koom nrog EMI / RFI shielded chav. Tsis tas li ntawd, nws yog siv los ua qhov chaw sib cuag nrog cov ntaub ntawv uas tsis yog-solderable xws li yas los yog txhuas thiab kom ntws hluav taws xob zoo li qub. Nws annealed, tooj liab-ci xim ua rau nws zoo meej rau kev kos duab thiab khoom siv tes ua haujlwm txij li nws yuav tsis tarnish. Ib daim ntawv nyias ntawm tooj liab lossis txhuas yog siv hauv cov ntawv ci thaiv. Feem ntau, qhov "foil" no yog txuas nrog cov cab kuj polyester los ua kom lub zog ntawm cable. Hom kab thaiv kab no, tseem hu ua "kab xev" shielding, tiv thaiv tag nrho cov neeg xyuas pib xaim nws tau qhwv ib ncig. Tsis muaj EMI los ntawm ib puag ncig tuaj yeem nkag mus. Txawm li cas los xij, cov cables no nyuaj heev rau kev daws teeb meem, tshwj xeeb tshaj yog thaum siv cov khoom sib txuas, vim tias cov ntawv ci hauv lub cable yog qhov muag heev. Tsis txhob sim ua kom cov kab thaiv hauv av kom tiav, cov xaim xaim feem ntau yuav ua haujlwm.

Tinted tooj liab shield yog qhia rau kev tiv thaiv ntau dua. Nws 95 feem pua ​​​​kev pab tsawg kawg yog muab los ntawm nws cov woven, tinned tooj liab muaj pes tsawg leeg. Nws yog qhov hloov pauv tshwj xeeb thiab muaj qhov nominal thickness ntawm.020 ", ua kom nws zoo meej rau kev siv los ua cov hlua khi rau cov khoom siv hauv hiav txwv, tsheb, thiab dav hlau.

Copper xov hlau yog woven rau hauv mesh rau braided insulated cables. Txawm hais tias muaj kev tiv thaiv tsawg dua li cov ntaub thaiv npog, braided shields yog qhov muaj zog dua. Thaum siv cov khoom sib txuas, lub braid yog qhov yooj yim dua rau kev txiav thiab tsim kom muaj kev tiv thaiv qis rau hauv av. Nyob ntawm seb lub braid ruaj khov li cas, braided shielding feem ntau muab 70 mus rau 95 feem pua ​​EMI tiv thaiv. Vim tias tooj liab ua hluav taws xob sai dua li txhuas thiab vim tias cov ntaub thaiv npog tsis tshua muaj peev xwm tiv thaiv kev puas tsuaj sab hauv, lawv muaj txiaj ntsig zoo dua li cov ntaub thaiv npog. Vim lawv cov kev ua tau zoo thiab ua haujlwm ntev, braided shield cables hnyav dua thiab kim dua cov ntaub thaiv npog.
