Kufunika Kwa Ma PCB Othamanga Kwambiri Pakupanga Zamagetsi

Pamene zamagetsi zikupitilira patsogolo zovuta komanso zimafuna mwachanguchizindikiro chotumiziras, ma PCB othamanga kwambiri akhala gawo lofunikira pakukula kwa ntchito yapamwambaskudera lonse lopanga zinthu.

Kuthamanga kwambiribolodi losindikizidwama (PCBs) akhala ofunikira kwambiri pakupanga zamagetsi, ndikupereka zinthu zingapo zofunika. Kwenikweni, ma PCB othamanga kwambiri amafalitsa bwinoelectromagnetic waves ndi kutayika kochepa ndikuwonetsetsakuthamanga kwambiri kwa chizindikiro. Zinthu zazikulu zomwe zimagwirizanitsidwa ndi ma PCB othamanga kwambiri ndi awa:

ZochepaDissipation Factor: Ma PCB othamanga kwambiri nthawi zambiri amawonetsa zinthu zotayika kuyambira 0.0019 mpaka 0.025, kuwonetsetsa kuti ndizochepakutayika kwa chizindikiro ndi kusunga chizindikiro chotumiziras.

ZochepaDielectric Constant: Ma PCB awa amakhala ndi dielectric yotsika komanso yokhazikika, yomwe imathandizira kusalalapafupipafupi kufalandi kuchepetsachizindikiro kuchedwa.

Kulimbana ndi Chemical: Kutha kwa ma PCB othamanga kwambiri kuti athe kupirira kukhudzana ndi mankhwala ndikofunika kwambiri, kuwonetsetsa kukana kwa dzimbiri komanso kukwanira kwa malo omwe ali ndi vuto lalikulu la mankhwala.

Kutsika Kwachinyezi Chochepa: Pokhala ndi madzi otsika kwambiri, ma PCB othamanga kwambiri ndi oyenerera kuti agwiritsidwe ntchito m'malo achinyezi ndi chinyezi.

ZochepaDimensional Kukhazikika: Ma PCB othamanga kwambiri amadziwika kuti amasunga kukula kwake komanso kukhala osakhudzidwa ndi kusintha kwa kutentha kwa chilengedwe.

Chifukwa cha makhalidwe amenewa, ntchito yawo ndi yofala. Komabe, opanga ma PCB akuyenera kuwonetsetsa kuti zotsatirazi zikutsatiridwa mosamala popanga ma PCB apamwamba kwambiri:

Sankhani PCB pafupipafupi chizindikiro: Ndikofunikira kukhazikitsa ma voliyumu ndi mphamvu zamagetsi, kugawa chilichonsendege yamagetsis, ndikuwunika momwe ma siginali osiyanasiyana amakhalira. Kuonjezera apo, kuchepetsa kulekerera ndi kuchepetsa phokoso ndizofunikira kwambiri.

Board stackupKukonzekera: Zofunikira za stackup layerziyenera kulinganizidwa bwino, poganizira za chinthu chenichenicho ndi malire ake.

Kukonzekera kwapansi: PCB iyenera kugawidwa m'magawo, ndikudzipatula koyenera kusungidwa m'malo omwe ali ndi magawo a digito ndi analogi kuti apewe kusokoneza.

Mphamvu ndindege yapansis: Kapangidwe ka PCB kakafotokozedwa, kumvetsetsa dongosolo lapansi ndikofunikira. Kugawanitsa ndege yapansi ndikofunikira, ndipo kuphatikiza kotsutsa pamodzi ndi chizindikiro chowongolera njira yobwerera ndikofunikira.

Chepetsani kukula kwa mapangidwe amtunda: Ma PCB othamanga kwambiri nthawi zambiri amakhala ndi mapepala ang'onoang'ono. Kuchepetsa danga kumathandiza kuchepetsa parasitic capacitancendikuwonjezera mphamvu zamakina.

Njira yapafupipafupi chizindikiros: Zizindikiro za ma frequency apamwamba zimadziwika kuti zimatulutsa ma radiation apamwamba. Kuyenda bwino kwa ma siginecha pafupipafupi kumatha kupewa kusokoneza pakati pa ma sigino.

Gwiritsani ntchito lamulo la 3W: Kutsatira lamulo la 3W kumatsimikizira kuti kukhulupirika kwa chizindikiro kumasungidwa, kukhazikitsa kusiyana pakati pa kufufuza ndi kuchepetsa kugwirizanitsa.

Gwiritsani ntchito lamulo la 20H: Kulumikizana pakati pa ndege zapansi ndi zamphamvu kungayambitse chiwopsezo pamapangidwe anu. Lamulo la 20H limatsimikizira kuti makulidwe pakati pa mphamvu zoyandikana ndi ndege zapansi ndi zazikulu kuposa ndege yamagetsi.

Kugwiritsa Ntchito High-Frequency PCBs

Kugwiritsa ntchito ma PCB othamanga kwambiri kukuchulukirachulukira, ndikugwiritsa ntchito kuphatikiza:

Njira zolumikizirana pazida zosefera, amplifiers,station stations, ndiwolandiras.

Ntchito zankhondo zopanga zida ndi mfuti.

Pulogalamu ya radars amene amatsogolera ndege ndi kupewa ngozi.

Zida zowunikira ndi kuyang'anira zofunikira pazachipatala.

Pomaliza

Ma PCB othamanga kwambiri ndi ofunikira pakupanga zamagetsi a PCB, kupereka zinthu zolimba zomwe zimawapangitsa kukhala chisankho chokondedwa pazida zamagetsi. Amakhala ndi gawo lalikulu pamapulogalamu ochita bwino kwambiri ndipo ali okonzeka kukhala ofunikira kwambiri chifukwa chakukula kwazovuta zamagetsi komanso kufunikira kwamitengo yotumizira ma siginecha mwachangu.
