EMI gasket msika wamakono? 

Mayendedwe a Msika wa EMI Gasket: Mawonedwe a Othandizira Kuchokera Pansi

Mumafunsa za msika wa EMI gasket, ndipo aliyense amalumphira ku 5G ndi magalimoto amagetsi. Izi sizolakwika, koma ndi yankho lapamwamba. Kusintha kwenikweni kuli mu sayansi yakuthupi komanso zankhanza, zomwe nthawi zambiri zimamanyalanyazidwa, zomwe timapanga tsiku ndi tsiku. Sikuti kungoteteza bwino; ndi za mtengo wantchito m'dziko lomwe makoma otchingidwa akucheperachepera komanso phokoso lowongolera likukulirakulira. Ndawona mapangidwe ambiri akulephera chifukwa amalingalira gasket yotengera deta yokha, osamvetsetsa momwe imakhalira pansi, pakapita nthawi, kapena pamzere wapadziko lonse lapansi.

Kuvina Kwazinthu: Kupitilira Ma Elastomers Otsogolera

Kwa zaka zambiri, silikoni wodzazidwa ndi siliva anali mfumu. Zodalirika, zodziwikiratu, koma zodula komanso zophatikizika zimayika zovuta zomwe zimasokoneza kudalirika kwanthawi yayitali. Zomwe zikuchitika pano ndikugawikana. Tikuwona kuchuluka kofunikira nsalu yazitsulo pamwamba pa thovu ma gaskets, makamaka mumagetsi ogula ndi makabati a telecom. Amapereka chitetezo chachikulu, mphamvu yotseka yotsika, ndipo ndizosavuta kupanga makina osonkhanitsira. Koma nsomba? Kukhazikika motsutsana ndi kuzungulira kwa zitseko mobwerezabwereza ndi kusindikiza chilengedwe kungakhale kofooka. Ndi kusinthanitsa.

Ndiye pali kukwera kwa mapulasitiki oyendetsa ndi zida zamtundu (FIP). FIP ndiyosangalatsa - imalonjeza kufananiza kwa geometry koyenera ndipo palibe zida zamawonekedwe achikhalidwe. Koma m'machitidwe, kuchiritsa nthawi ndikolepheretsa kupanga, ndipo kulephera kumamatira pamalo opaka ufa ndi mutu wamba. Ndikukumbukira pulojekiti ya chipangizo chojambula chachipatala pomwe mzere wa FIP unali ndi 2% yolephera pokhapokha pomamatira. Tinataya kwa milungu ingapo kuti tithetse mavuto tisanasinthiretu kudulidwa conductive elastomer vula ndi zomatira zomwe sizimva kupanikizika. Mfundo: chizolowezi sichiri njira yabwino nthawi zonse.

Ngakhale m'zinthu zachikhalidwe, ma formulations akusintha. Ma silicones otsika kwambiri odzazidwa ndi nickel-graphite kapena aluminiyamu ayamba kugwiritsidwa ntchito pomwe kulemera ndi mtengo wake ndizofunikira, ngakhale mumapereka zotchinga zina pama frequency apamwamba. Ndiko kusinthasintha kosalekeza pakati pa magwiridwe antchito amagetsi, zida zamakina, ndi bilu yazinthu.

The 5G ndi IoT Finyani: Ndi Za Kachulukidwe ndi Mafupipafupi

Inde, 5G ndi dalaivala wamkulu, koma osati momwe ambiri amaganizira. Sizokhudza malo oyambira ambiri. Zimakhudza kuchulukana kwazinthu zamisala mkati mwa maselo ang'onoang'onowo ndikukankhira mu millimeterWave. Pa 28 GHz ndi pamwamba, masewera oteteza amasintha kwathunthu. Ma gasket seams amakhala owongolera ngati simusamala. Mchitidwewu ndi wolunjika ultra-low compression force mapangidwe ndi ma gaskets okhala ndi mawonekedwe abwino kwambiri, osasinthasintha kuti azitha kulumikizana bwino popanda kusokoneza ma PCB osalimba kapena m'mipanda.

Pazida za IoT, zovuta ndizosiyana. Ganizirani zanzeru mita, masensa mafakitale. Mtengo ndi mfumu, komabe muyenera kudutsa malamulo a EMC. Izi zikupangitsa kutengera zida zotsika mtengo ngati zopangira ma conductive kapena zolumikizira zala zachitsulo nthawi zina. Zomwe zikuchitika pano ndi chitetezo chokwanira. Sitikupangira zankhondo; tikukonzekera kudutsa FCC Gawo 15B ndi malire omasuka ndikupulumuka zaka khumi kunja. Izi zadzetsa chiwonjezeko kwa opanga apadera omwe amatha kupereka kusasinthika pamlingo wokwera komanso mtengo wotsika.

Ndinagwira ntchito ndi kasitomala pa piritsi lolimba. Mapangidwe oyambilira adagwiritsa ntchito makina opangira elastomer gasket. Zinagwira ntchito mwangwiro, koma mtengo wa unit unali kupha polojekitiyo. Tinasinthira ku muyezo waya mauna gasket yokhala ndi pachimake choluka kuchokera kwa ogulitsa omwe amatha kupereka voliyumu yofunikira. Kutchinga kwatsika kuchoka pa 80 dB kufika pafupifupi 65 dB, koma kunali kokwanira kugwiritsa ntchito. Ntchitoyi idapulumutsidwa. Nthawi zina, chizolowezicho chimakhala chongobwerera kuchokera ku njira yabwino kupita ku njira yabwino kwambiri.

Supply Chain ndi Regional Shifts

Kudalirana kwa mayiko mu gawo ili ndi chenicheni, koma kukhwima. Zaka khumi zapitazo, aliyense ankayang'ana kwa ogulitsa ochepa kwambiri aku US kapena ku Europe. Tsopano, mawonekedwe ake ndi osiyana. Opanga zabwino ku Asia atseka kusiyana kwakukulu, makamaka pazambiri ndi zida. Izi zabweretsa kutsika kwamitengo ndikufupikitsa nthawi yotsogolera pazinthu wamba.

Tengani kampani ngati Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd.. Kuchokera ku Yongnian, Hebei-mtima wamakampani othamanga kwambiri ku China-malo awo pafupi ndi njira zazikulu zoyendera monga Beijing-Guangzhou Railway ndi National Highway 107 si mzere chabe mu kabuku (https://www.zitaifasteners.com). Zimatanthawuza kuchita bwino kwazinthu zopangira komanso kutumiza katundu womalizidwa. Kwa ogula voliyumu yamagetsi oyendetsa bwino kapena zomangira zotchingira, izi ndizofunikira kwambiri kuposa momwe mungaganizire. Amayimira gawo lamsika lomwe limachita bwino kwambiri pazigawo zachitsulo zamphamvu kwambiri, zomwe ndi maziko a makina ambiri oyika ma gasket. Sizinthu zokhazokha za gasket; ndizokhudza mawonekedwe onse a mawonekedwe.

Komabe, pakupanga zinthu zotsogola, zopangira eni kapena ntchito zofunika kwambiri zakuthambo/chitetezo, ma suppliers okhazikitsidwa aku Western akadali ndi malire amphamvu. Zomwe zikuchitika ndikuphatikizana: zinthu zokhazikika, zapamwamba kwambiri zikuchokera kumakampani ampikisano apadziko lonse lapansi, pomwe niche, mayankho ochita bwino kwambiri amakhalabe ndi akatswiri apadera. Njira yopezera nzeru tsopano ikuphatikiza njira ziwiri.

Kuphatikiza ndi Design-In Imperative

Cholakwika chachikulu chomwe ndikuwona ndikuwona EMI gasket ngati kuganiza motsatira, zomwe mumamatira mumsewu pambuyo popanga mafakitale. Ndilo njira yochepetsera mtengo komanso zovuta zogwirira ntchito. Chodziwika bwino ndi kuyanjana koyambirira. Timabweretsedwa mu gawo la mapangidwe kuti tilangize kukula kwa groove, kumalizidwa kwapamwamba, ndi malire a kuponderezana.

Izi zimabweretsa mayankho ophatikizika. Ganizirani za ma gaskets ophatikizidwa ndi zisindikizo zachilengedwe, kapena ma gaskets omwe amaperekanso njira zoyambira zigawo zingapo. Palinso kukula kwa ma gaskets opangidwa ndi makonda omwe amathetsa mavuto angapo nthawi imodzi-kuteteza IC yeniyeni, kuyang'anira kukhudzana ndi kutentha, ndi kupereka chisindikizo chafumbi. Ndizokwera mtengo kwambiri kutsogolo koma zimapulumutsa ndalama zambiri panthawi ya msonkhano ndi kukonzanso.

Chitsanzo pa mfundo: gawo la magalimoto a lidar. Nyumbayo inali yovuta kuponya magnesium. Dongosolo loyambirira linagwiritsa ntchito ma gaskets anayi osiyana ndi zingwe zoyambira pansi. Pogwira ntchito kuchokera ku mtundu woyamba wa CAD, tidakonza zokhala ndi lobeti imodzi Mtengo wa EMI opangidwa kuchokera ku conductive thermoplastic yomwe idalowa m'malo mwa msonkhano, kupereka chitetezo, kuyika pansi, ndi chotchinga chinyezi mu sitepe imodzi. Idawonjezera 15% pamtengo wa gasket koma idachepetsa nthawi ya msonkhano ndi 70% ndikuchotsa zigawo zitatu zachiwiri. Mchitidwewu ukuyenda kuchokera ku gawo lazamalonda kupita ku kachitidwe kakang'ono kamtengo wapatali.

Sustainability ndi Lifecycle Pressures

Uwu ndiye mchitidwe wachete womwe ukukhala mkokomo. REACH, RoHS, ndi zofuna za makasitomala pazogulitsa zobiriwira zimakhudza mwachindunji zosankha zakuthupi. Zida zina zodzaza ndi ma plating zimayang'aniridwa. Kusinthaku kumalowera kuzinthu zopanda halogen, zopangira gasket zobwezerezedwanso (monga zitsulo zolekanitsidwa ndi zida za elastomer), ndi zinthu zokhalitsa kuti zichepetse zinyalala.

Kukaniza set resistance sikulinso kayezedwe kantchito; ndi yokhazikika. Gasket yomwe imasunga chisindikizo chake kwa zaka 15 m'malo mwa 10 imatanthawuza nthawi yocheperako yautumiki, gawo limodzi lochepa lolephera m'munda. Tikuyesa moyo wochulukirapo kuposa kale, kutengera zaka zakuyenda panjinga zotentha komanso kuponderezana m'masabata.

Imasinthanso kusanthula kulephera. Posachedwapa tinali ndi ma gaskets mu zida zapanja za telecom zomwe zidatsika mwachangu kuposa momwe timayembekezera. Wopalamula sanali wodzitetezera; chinali chomangira cha silicone chomwe chimasweka pansi pamikhalidwe ya UV ndi ozoni m'mphepete mwa nyanja. Kukonzaku kunaphatikizapo kupanga polima pang'ono, kokwera mtengo kwambiri. Zomwe zikuchitikazi zikutikakamiza kuyang'ana chithunzi chonse cha mankhwala ndi chilengedwe, osati zamagetsi zomwe zili patsamba limodzi la datasheet.

Kuyang'ana M'tsogolo: The Data Center ndi AI Wildcard

Aliyense amalankhula ma EVs ndi 5G, koma kukakamiza kwakukulu kotsatira kungakhale malo opangira deta komanso ma seva a AI. Kuchulukitsitsa kwamphamvu ndi misala, ndipo phokoso losintha kuchokera kukusintha kwamagetsi ndi njira zothamanga kwambiri za SerDes zikupanga vuto latsopano la EMI mkati mwa nduna. Tikuyamba kuwona ma RFQ a ma gaskets omwe amatha kunyamula katundu wotentha kwambiri, amapereka chitetezo pamlingo wa board-level ndi rack-level, ndipo ndi othandiza - matekinoloje amayenera kutsegula ndi kutseka zitseko kambirimbiri popanda kuwononga chisindikizo.

Izi zitha kukankhira kutengera kwazinthu zatsopano zosakanizidwa kapena malingaliro agasket (ngakhale akadali olankhula labu). Nthawi yomweyo, pamafunika kulondola kwambiri pakupanga gasket kuti muwonetsetse kulumikizana kofanana pazitseko zazikulu kwambiri za kabati. Mipikisano yololera imakhala yovuta. Zikumveka ngati zovuta zomwe tidakumana nazo muzamagetsi zankhondo zaka 20 zapitazo tsopano zikugunda malo azamalonda.

Ndiye kodi zimenezi zikutisiya kuti? Msika wa EMI gasket sutsata njira imodzi; imakokedwa m'njira khumi ndi ziwiri ndi mapulogalamu osiyanasiyana. Ulusi wogwirizanitsa ndikusuntha kuchoka ku gawo losavuta, loteteza katundu kupita ku gawo lofunikira, lopangidwa mwaluso. Kupambana tsopano kumadalira pang'ono pakukhala ndi zinthu zabwino kwambiri m'kalozera komanso zambiri pakumvetsetsa dongosolo - kapangidwe ka makina, kupsinjika kwa chilengedwe, kamangidwe kake, ndi mtengo wonse wa umwini. Tsambali ndiye poyambira kukambirana.
