EMI Shielding Gasket

A: Ib qho EMI (Electromagnetic Interference) shielding gasket, tseem hu ua EMC (Electromagnetic Compatibility) gasket, yog cov khoom siv tshwj xeeb siv hauv cov tshuab hluav taws xob thiab hluav taws xob los tiv thaiv kev cuam tshuam ntawm electromagnetic cuam tshuam los yog kev cuam tshuam xov tooj cua (EMI / RFI) ntawm ob qhov nyob ib sab. qhov chaw, feem ntau yog qhov muaj qhov khoob lossis cov hlua khi hauv cov khoom siv hluav taws xob lossis cov txee.

Lub hom phiaj tseem ceeb ntawm EMI shielding gaskets yog tsim kom muaj kev sib khi ntawm ob qhov chaw, xws li mating nto ntawm ib qho hluav taws xob enclosure lossis cov npoo ntawm PCB (Printed Circuit Board). Lub foob no pab kom muaj cov khoom siv hluav taws xob los ntawm cov khoom siv hluav taws xob sab hauv thiab thaiv kev cuam tshuam sab nraud los ntawm kev nkag mus rau hauv lub thawv. EMI shielding gaskets feem ntau siv hauv cov ntawv thov xws li cov khoom siv sib txuas lus, cov khoom siv kho mob, tub rog thiab aerospace electronics, khoom siv hluav taws xob, thiab lwm yam.

Cov yam ntxwv tseem ceeb ntawm EMI shielding gaskets suav nrog:
1.Conductive Materials:Cov gaskets no feem ntau yog ua los ntawm cov khoom siv hluav taws xob, xws li cov hlau-filled elastomers (rubbers) los yog cov ntaub ntawv ua npuas dej.

2.Suab thiab Profile:EMI shielding gaskets tuaj nyob rau hauv ntau yam duab thiab profiles, nrog rau gaskets, O-rings, thiab sawb gaskets, kom haum rau sib txawv sealing kev cai.

3. Compression:Thaum ob qhov chaw raug coj los ua ke, lub gasket yog compressed, kom ntseeg tau tias muaj hluav taws xob zoo thiab lub foob kaw ntom nti.

4.Conductive Adhesive:Qee qhov EMI shielding gaskets muaj cov nplaum nplaum rau ntawm ib lossis ob sab los pab ua kom lub gasket rau qhov chaw mating.

5.Environmental Resistance:Ntau EMI shielding gaskets yog tsim los tiv thaiv ib puag ncig hnyav, nrog rau qhov kub thiab txias, noo noo, thiab tshuaj lom neeg.

6. Ua raws li tus qauv:EMI shielding gaskets feem ntau yog tsim los ua kom tau raws li cov qauv thiab cov kev cai tshwj xeeb, xws li MIL-STD-461 rau kev siv tub rog lossis FCC cov cai rau cov neeg siv khoom siv hluav taws xob.

Los ntawm kev siv EMI shielding gaskets, cov tuam ntxhab tuaj yeem txhim kho cov khoom siv hluav taws xob sib raug zoo ntawm lawv cov khoom, txo qhov kev pheej hmoo ntawm kev cuam tshuam ntawm cov khoom siv hluav taws xob, thiab xyuas kom meej tias cov khoom siv hluav taws xob ua tau raws li cov kev cai rau kev tso tawm thiab cuam tshuam rau kev cuam tshuam.

Ntawm SHENZHEN EMIS ELECTRON MATERIALS LTD., CO, peb tau mob siab rau muab cov kev daws teeb meem EMI shielding uas txhawb nqa koj cov khoom nrog qib siab tshaj ntawm kev tiv thaiv electromagnetic cuam tshuam. Koom tes nrog peb rau kev siv technology tshiab, kev ntseeg siab, thiab kev cog lus rau kev ua tau zoo.

A: EMI (Electromagnetic Interference) shielding gaskets ua haujlwm los ntawm kev tsim ib qho kev thaiv uas tiv thaiv kev hla ntawm hluav taws xob hluav taws xob los yog cuam tshuam ntawm ob qhov chaw nyob ib sab. Cov gaskets no yog tsim los muab hluav taws xob conductivity thiab lub kaw ntom nti, zoo thaiv cov hluav taws xob tsis zoo thiab ua kom muaj kev ncaj ncees ntawm cov khoom siv hluav taws xob. Nov yog qhov lawv ua haujlwm li cas:
1.Conductive Materials:EMI shielding gaskets feem ntau yog ua los ntawm cov khoom siv hluav taws xob, xws li cov hlau uas muaj elastomers (cov roj hmab) los yog cov ntaub ntawv ua npuas dej. Cov ntaub ntawv no muaj peev xwm ua tau hluav taws xob.

2. Compression:Thaum ob qhov chaw lossis cov khoom sib txuas los yog raug coj los ua ke, EMI shielding gasket yog compressed ntawm lawv. Qhov compression no ua kom zoo hluav taws xob sib txuas ntawm lub gasket thiab mating nto, tsim kom muaj txoj hauv kev conductive.

3.Kev sib khi:Ntxiv rau lawv cov khoom siv hluav taws xob, EMI shielding gaskets kuj tseem ua cov ntsaws ruaj ruaj. Lawv sau qhov khoob, seams, lossis cov pob qij txha hauv cov khoom siv hluav taws xob, PCBs, lossis lwm yam khoom siv uas muaj kev cuam tshuam electromagnetic tuaj yeem nkag mus lossis khiav tawm.

4.Blocking EMI:Electromagnetic cuam tshuam muaj xws li electromagnetic vuag (radiofrequency radiation) tsim los ntawm cov khoom siv hluav taws xob lossis lwm qhov chaw. Thaum cov nthwv dej no ntsib EMI shielding gasket, uas tam sim no yog ib feem ntawm txoj kev coj ua, lawv ua rau cov hluav taws xob tam sim no hauv cov khoom siv gasket.

5.Absorption thiab Reflection:Cov induced hluav taws xob tam sim no ntws los ntawm cov khoom siv hluav taws xob gasket thiab, nyob rau hauv cov txheej txheem, nqus thiab dissipate lub zog ntawm cov khoom siv hluav taws xob los. Qhov kev nqus no txo ​​qhov kev siv ntawm kev cuam tshuam.

6. Kev xav:Qee qhov hluav taws xob nthwv dej tau cuam tshuam los ntawm qhov chaw tiv thaiv vim yog cov khoom siv hluav taws xob ntawm cov khoom siv gasket, tiv thaiv lawv los ntawm kev nkag los yog khiav tawm.

7.Complete Enclosure:Txhawm rau kom ua tiav EMI tiv thaiv zoo, tag nrho cov khoom siv hluav taws xob lossis thaj chaw muaj kev txhawj xeeb yuav tsum tau muab ntim nrog cov khoom siv hluav taws xob, kom ntseeg tau tias tsis muaj qhov khoob lossis qhov chaw tsis muaj kev tiv thaiv.

8.Multiple Layers:Nyob rau hauv cov ntaub ntawv uas yuav tsum tau ntau dua ntawm shielding, ntau txheej ntawm shielding cov ntaub ntawv thiab gaskets yuav siv tau los txhim kho kev tiv thaiv.

Los ntawm kev siv EMI shielding gaskets, cov tuam txhab lag luam tuaj yeem tswj tau zoo thiab txo qhov cuam tshuam ntawm electromagnetic cuam tshuam, kom ntseeg tau tias cov khoom siv hluav taws xob ua haujlwm tau zoo thiab ua raws li cov qauv kev sib raug zoo ntawm electromagnetic compatibility (EMC) thiab cov kev cai. Cov gaskets no ua lub luag haujlwm tseem ceeb hauv kev lag luam uas muaj teeb meem kev ncaj ncees, kev ruaj ntseg cov ntaub ntawv, thiab kev tiv thaiv kev cuam tshuam yog qhov tseem ceeb, xws li kev sib txuas lus, aerospace, khoom siv kho mob, thiab cov khoom siv hluav taws xob.

A: EMI shielding gaskets tuaj yeem tsim los ntawm ntau yam khoom siv, nyob ntawm cov kev xav tau tshwj xeeb thiab daim ntawv thov lawv tau npaj rau. Kev xaiv cov khoom siv tseem ceeb heev rau lawv cov kev ua tau zoo hauv kev thaiv electromagnetic cuam tshuam zoo. Nov yog qee yam khoom siv uas siv:
1.Metal-Filled Elastomers:Cov gaskets no yog tsim los ntawm kev sib xyaw cov khoom siv hlau, xws li nyiaj, npib tsib xee, lossis tooj liab, nrog cov khoom siv elastomeric zoo li silicone lossis neoprene. Kev sib xyaw ntawm cov hlau thiab elastomer muab ob qho tib si hluav taws xob conductivity thiab yooj. Hlau-filled elastomers feem ntau yog siv thaum yuav tsum tau compressible gasket, raws li lawv tuaj yeem ua raws li qhov tsis sib xws.

2.Conductive Fabric-over-Foam:Hom gasket no muaj cov txheej txheem ntawm cov ntaub ntawv laminated mus rau ib qho ua npuas ncauj substrate. Ua npuas ncauj muab qhov tsim nyog compressibility thiab sealing zog, thaum lub conductive ntaub muaj conductivity. Conductive fabric-over-foam gaskets feem ntau yog siv hauv cov khoom siv hluav taws xob thiab tuaj yeem ua haujlwm zoo ntawm ntau zaus.

3.Conductive Roj Hmab:Conductive roj hmab gaskets feem ntau yog tsim los ntawm silicone roj hmab uas muaj cov khoom siv hluav taws xob. Cov gaskets no paub txog lawv cov durability thiab resilience. Lawv feem ntau siv rau hauv cov ntawv thov uas xav tau kev sib khi ib puag ncig ntxiv rau EMI shielding.

4. Hlau Foils:Cov ntawv nyias nyias ntawm cov hlau, xws li tooj liab lossis txhuas, tuaj yeem siv ua EMI shielding gaskets. Cov ntawv ci no feem ntau ua ke nrog cov nplaum rov qab, tso cai rau lawv yooj yim siv rau qhov chaw sib txuas ntawm cov khoom siv hluav taws xob lossis PCBs. Hlau foils yog tshwj xeeb tshaj yog ua tau zoo nyob rau hauv high zaus.

5.Conductive Plastics:Qee cov gaskets yog tsim los ntawm cov yas conductive uas muaj cov khoom siv hluav taws xob ntxiv. Cov ntaub ntawv no tuaj yeem raug molded lossis extruded rau hauv ntau yam duab thiab siv rau hauv cov ntawv thov uas nyiam cov khoom siv tsis yog hlau.

6. Hlau Mesh:Qee qhov xwm txheej, cov ntaub ntawv hlau mesh, feem ntau yog ua los ntawm cov hlau, yog siv los ua EMI shielding gaskets. Cov meshes no yog tsim los muab ib qho kev tiv thaiv kab mob thaum tso cai rau qhov cua los yog pom kev hauv cov ntawv thov xws li RF-shielded windows lossis vents.
