EMI gasket kev lag luam tiam sis? 

EMI Gasket Kev Lag Luam Kev Lag Luam: Tus Kws Tshaj Lij Saib Xyuas hauv av

Koj nug txog EMI gasket kev lag luam tiam sis, thiab txhua tus dhia mus rau 5G thiab hluav taws xob tsheb. Qhov ntawd tsis yog qhov yuam kev, tab sis nws yog cov lus teb saum npoo av. Qhov kev hloov pauv tiag tiag yog nyob rau hauv cov ntaub ntawv tshawb fawb thiab kev ua phem, feem ntau saib tsis taus, kev cuam tshuam ntawm engineering peb ua txhua hnub. Nws tsis yog hais txog kev tiv thaiv kev ua haujlwm ntxiv lawm; nws yog hais txog tus nqi-ib-kev ua tau zoo nyob rau hauv lub ntiaj teb no uas cov phab ntsa thaiv tau thinner thiab kev tswj lub suab nrov nrov. Kuv tau pom ntau tus qauv tsis zoo vim lawv spec'd gasket raws li daim ntawv teev lus ib leeg, tsis nkag siab tias nws coj li cas hauv compression, dhau sijhawm, lossis hauv kab sib dhos tiag tiag.

Cov Khoom Dance: Tshaj Tawm Elastomers

Rau xyoo, silver-filled silicone yog huab tais. Txhim khu kev qha, kwv yees, tab sis kim thiab nrog compression teeb teeb meem uas haunt mus ntev kev cia siab. Txoj kev tam sim no yog fragmentation. Peb tab tom pom qhov kev xav tau nce ntxiv metalized ntaub tshaj ua npuas ncauj gaskets, tshwj xeeb tshaj yog nyob rau hauv cov neeg siv khoom siv hluav taws xob thiab telecom txee. Lawv muaj kev tiv thaiv zoo, tsis tshua muaj zog kaw, thiab yooj yim rau automate hauv kev sib dhos. Tab sis tus ntes? Durability tiv thaiv lub qhov rooj rov ua dua thiab ib puag ncig sealing tuaj yeem yog qhov tsis muaj zog. Nws yog kev sib pauv.

Tom qab ntawd muaj qhov nce ntawm cov khoom siv hluav taws xob thiab cov khoom siv hauv qhov chaw (FIP). FIP yog qhov nthuav - nws cog lus tias zoo meej geometry txuam thiab tsis muaj cuab yeej rau cov duab kev cai. Tab sis nyob rau hauv kev xyaum, lub sij hawm kho yog ib tug ntau lawm bottleneck, thiab adhesion tsis ua hauj lwm ntawm hmoov-coated nto yog ib qho mob taub hau. Kuv nco qab txog qhov project rau cov khoom siv kho mob uas FIP kab muaj 2% tsis ua hauj lwm tus nqi ntawm adhesion. Peb poob lub lis piam daws teeb meem ua ntej hloov mus rau kev txiav ua ntej conductive elastomer strip nrog lub siab-rhiab nplaum nplaum. Zaj lus qhia: kev sib txawv tsis yog ib qho kev daws teeb meem.

Txawm nyob rau hauv cov ntaub ntawv tsoos, formulations yog evolved. Tsawg-density silicones ntim nrog npib tsib xee-graphite lossis txhuas tau txais hauv av rau cov ntawv thov qhov hnyav thiab tus nqi tseem ceeb, txawm tias koj txi qee qhov thaiv ntawm ntau zaus. Nws yog qhov sib npaug tas li ntawm kev ua haujlwm hluav taws xob, cov khoom siv hluav taws xob, thiab cov nqi ntawm cov ntaub ntawv.

5G thiab IoT Squeeze: Nws Hais Txog Qhov Ceev thiab Zaus

Yog lawm, 5G yog tus tsav tsheb loj, tab sis tsis yog raws li feem ntau xav. Nws tsis yog hais txog ntau lub hauv paus chaw nres tsheb. Nws yog hais txog qhov insane tivthaiv ntom hauv cov hlwb me me thiab thawb mus rau millimeterWave. Ntawm 28 GHz thiab siab dua, qhov kev tiv thaiv kev ua si hloov pauv tag nrho. Gasket seams ua waveguides yog tias koj tsis ceev faj. Cov qauv yog mus rau ultra-low compression quab yuam tsim thiab gaskets nrog finer, zoo ib yam nto profiles kom muaj intimate kev sib cuag yam tsis deforming fragile PCBs los yog enclosures.

Hauv IoT cov khoom siv, qhov kev sib tw sib txawv. Xav txog ntse meters, muaj sensors. Tus nqi yog huab tais, tab sis koj tseem yuav tsum dhau EMC cov cai. Qhov no yog tsav kev txais yuav cov khoom siv qis dua li cov roj hmab conductive lossis txawm tias clip-on hlau caij nplooj ntoos hlav ntiv tes hauv qee kis. Cov qauv ntawm no yog zoo txaus shielding. Peb tsis tsim rau cov tub rog specs; peb tab tom tsim kom dhau FCC Tshooj 15B nrog cov paj zoo nkauj thiab muaj sia nyob ib xyoo caum sab nraum zoov. Qhov no tau ua rau muaj kev loj hlob rau cov tuam txhab tshwj xeeb uas tuaj yeem xa cov khoom sib xws ntawm qhov ntim siab thiab tus nqi qis.

Kuv tau ua haujlwm nrog tus neeg siv khoom ntawm lub ntsiav tshuaj rugged. Tus tsim thawj zaug siv cov kev cai-molded conductive elastomer gasket. Nws ua haujlwm zoo kawg nkaus, tab sis tus nqi tsev tau tua qhov project. Peb hloov mus rau tus qauv kab mesh gasket nrog ib tug knitted core los ntawm tus neeg muag khoom uas tuaj yeem xa cov ntim xav tau. Lub shielding poob los ntawm 80 dB mus txog 65 dB, tab sis nws tseem ntau tshaj qhov txaus rau daim ntawv thov. Qhov project tau txais kev cawmdim. Qee zaum, qhov sib txawv yog hais txog kev rov qab los ntawm qhov kev daws teeb meem zoo tshaj plaws rau qhov siv tau tshaj plaws.

Cov Kev Pabcuam Kev Lag Luam thiab Kev Ua Haujlwm Hauv Cheeb Tsam

Globalization nyob rau hauv cov sector no yog tiag tiag, tab sis nws yog maturing. Ib xyoo caum dhau los, txhua leej txhua tus saib mus rau ib tug puv tes ntawm loj US los yog European cov khoom tshwj xeeb. Tam sim no, toj roob hauv pes txawv. Cov tuam txhab lag luam zoo hauv Asia tau kaw qhov sib txawv tseem ceeb, tshwj xeeb tshaj yog rau cov qauv profiles thiab cov ntaub ntawv. Qhov no tau ua rau poob qis rau cov nqi thiab ua rau lub sijhawm luv luv rau cov khoom siv.

Coj ib lub tuam txhab zoo li HANDAN ZITAI FREWER RAUG UA MOV., Ltd.. Raws li nyob rau hauv Yongnian, Hebei - lub plawv ntawm Tuam Tshoj txoj kev lag luam fastener - lawv qhov chaw nyob ze cov kev thauj loj xws li Beijing-Guangzhou Railway thiab National Highway 107 tsis yog ib txoj kab hauv phau ntawv qhia (https://www.zitaifasteners.com). Nws txhais mus rau logistical efficiency rau raw khoom kom tsawg thiab cov khoom tiav shipping. Rau ib tug ntim buyer ntawm tus qauv conductive gaskets los yog shielding fasteners, qhov no infrastructure tseem ceeb tshaj li koj xav. Lawv sawv cev rau ib ntu ntawm kev ua lag luam uas ua tau zoo ntawm cov ntim siab, precision hlau qhov chaw, uas yog lub hauv paus rau ntau lub tshuab gasket. Nws tsis yog hais txog cov khoom siv gasket xwb; nws yog hais txog tag nrho cov interface system.

Txawm li cas los xij, rau kev txiav-ntug, kev tsim cov khoom tsim los yog lub hom phiaj tseem ceeb ntawm aerospace / kev tiv thaiv daim ntawv thov, cov neeg tsim khoom sab hnub poob tseem tuav lub zog. Cov qauv yog bifurcation: tus qauv, cov khoom ntim siab tau nce los ntawm kev sib tw thoob ntiaj teb hubs, thaum niche, cov kev daws teeb meem siab tseem nyob nrog cov neeg tsim khoom tshwj xeeb. Lub tswv yim muab khoom ntse tam sim no suav nrog txoj hauv kev dual-track.

Kev sib xyaw ua ke thiab tsim-hauv qhov tseem ceeb

Qhov yuam kev loj tshaj plaws uas kuv pom yog kho EMI gasket raws li qhov kev xav tom qab, ib yam dab tsi koj lo rau hauv qhov zawj tom qab kev tsim kho tau khov. Qhov no yog ib daim ntawv qhia rau tus nqi overruns thiab teeb meem kev ua haujlwm. Qhov tseeb qauv yog mus rau kev sib koom ua ntej. Peb tab tom raug coj mus rau theem tsim los qhia txog qhov ntev ntawm qhov zawj, qhov chaw tiav, thiab kev txwv kev txwv.

Qhov no ua rau cov kev daws teeb meem sib xyaw. Xav txog cov gaskets ua ke nrog ib puag ncig cov ntsaws ruaj ruaj, los yog gaskets uas tseem muab txoj hauv kev rau ntau yam khoom. Kuj tseem muaj kev loj hlob nyob rau hauv cov kev cai zoo li cov gaskets uas daws tau ntau yam teeb meem ib zaug - tiv thaiv ib qho tshwj xeeb IC, tswj cov dab dej kub, thiab muab cov plua plav foob. Nws kim dua pem hauv ntej tab sis txuag tau txiaj ntsig hauv lub sijhawm sib dhos thiab rov ua haujlwm.

Ib rooj plaub nyob rau hauv taw tes: ib tug automotive lidar module. Lub tsev yog ib tug complex magnesium tuag-casting. Thawj txoj kev npaj siv plaub cais gaskets thiab grounding straps. Los ntawm kev ua haujlwm los ntawm thawj CAD qauv, peb tau npaj ib qho, ntau lub lobed EMI Gasket ua los ntawm cov thermoplastic conductive uas snapped rau hauv qhov chaw thaum lub sij hawm sib dhos, muab kev tiv thaiv, grounding, thiab ib qho kev tiv thaiv ya raws hauv ib kauj ruam. Nws ntxiv 15% rau tus nqi gasket tab sis txo lub sij hawm sib dhos los ntawm 70% thiab tshem tawm peb yam khoom thib ob. Cov qauv yog txav los ntawm ib feem ntawm cov khoom muag mus rau tus nqi-engineered subsystem.

Sustainability thiab Lifecycle Pressures

Qhov no yog txoj kev ntsiag to uas dhau los ua suab nrov. REACH, RoHS, thiab cov neeg siv khoom xav tau rau cov khoom lag luam ntsuab yog cuam tshuam ncaj qha rau cov khoom xaiv. Qee cov ntaub ntawv muab tub lim thiab cov txheej txheem plating yog nyob rau hauv kev tshuaj xyuas. Kev hloov pauv mus rau cov ntaub ntawv tsis muaj halogen, cov khoom siv rov ua dua tshiab (xws li cov hlau sib cais thiab cov khoom siv elastomer), thiab cov khoom siv ntev dua los txo cov khoom pov tseg.

Compression teeb kuj tsis yog ib qho kev ntsuas kev ua tau zoo xwb; nws yog ib tug sustainability. Lub gasket uas tuav nws lub foob rau 15 xyoo es tsis txhob 10 txhais tau hais tias ib qho kev pab cuam tsawg dua, ib qho tsis muaj peev xwm ntawm qhov tsis ua hauj lwm hauv thaj teb. Peb tab tom ua ntau lub neej kev sim dua li yav dhau los, simulating xyoo ntawm thermal cycling thiab compression nyob rau hauv lub lis piam.

Nws kuj hloov tsis ua hauj lwm tsom xam. Peb tsis ntev los no tau muaj ib pawg ntawm gaskets nyob rau sab nraum zoov telecom iav uas degraded sai tshaj qhov xav tau. Tus neeg ua txhaum tsis yog tus tiv thaiv muab tub lim; nws yog cov silicone binder tawg nyob rau hauv tshwj xeeb UV thiab ozone tej yam kev mob nyob rau hauv ib tug ntug hiav txwv dej. Qhov kev txhim kho koom nrog me ntsis, kim dua polymer formulation. Qhov sib txawv yog yuam kom peb saib tag nrho cov tshuaj lom neeg thiab ib puag ncig daim duab, tsis yog cov hluav taws xob specs ntawm nplooj ntawv ib qho ntawm cov ntaub ntawv.

Saib tom ntej: Lub Chaw Cov Ntaub Ntawv thiab AI Wildcard

Txhua leej txhua tus tham EVs thiab 5G, tab sis lub ntsiab lus tseem ceeb tom ntej no yuav yog cov chaw muaj ntaub ntawv siab thiab AI server racks. The power densities are insane, and the switching noise from power conversion and high-speed SerDes channels is creating a new EMI nightmare inside the cabinet. Peb tab tom pib pom RFQs rau gaskets uas tuaj yeem tswj tau cov thermal loads siab dua, muab kev tiv thaiv ntawm ob lub rooj tsavxwm-theem thiab khib-theem, thiab muaj kev pabcuam-techs yuav tsum tau qhib thiab kaw qhov rooj ntau pua zaus yam tsis muaj kev puas tsuaj rau lub foob.

Qhov no tuaj yeem thawb kev siv cov ntaub ntawv tshiab hybrid lossis txawm tias lub ntsiab lus tseem ceeb ntawm gasketing (txawm hais tias tseem yog feem ntau lab-hais lus). Ntau tam sim ntawd, nws xav tau qhov tseeb tshaj plaws hauv kev tsim khoom gasket kom ntseeg tau tias kev sib cuag tsis sib xws thoob plaws lub qhov rooj loj heev. Cov kab mob siab ntev dhau los ua qhov tseem ceeb. Nws zoo li cov teeb meem peb tau ntsib hauv tub rog electronics 20 xyoo dhau los tam sim no tau tsoo cov chaw lag luam cov ntaub ntawv.

Yog li ntawd, qhov twg yuav tso peb? EMI gasket kev ua lag luam tsis ua raws li ib qho qauv; nws raug rub rau hauv kaum ob cov lus qhia los ntawm cov ntawv thov sib txawv. Cov xov sib koom ua ke yog qhov txav los ntawm qhov yooj yim, cov khoom tiv thaiv ib feem mus rau qhov tseem ceeb, kev tsim kho qhov sib txuas. Kev vam meej tam sim no nyob ntawm tsawg dua ntawm kev muaj cov khoom zoo tshaj plaws hauv phau ntawv teev npe thiab ntau ntxiv ntawm kev nkag siab txog qhov system-kev tsim kho tshuab, kev ntxhov siab ib puag ncig, txheej txheem sib dhos, thiab tag nrho cov nqi ntawm cov tswv cuab. Cov ntaub ntawv tsuas yog qhov pib ntawm kev sib tham.
