Kufunika kwa Ma PCB Omwe Amasinthasintha Kwambiri Pakupanga Zamagetsi
Pamene zamagetsi zikupitilirabe kupita patsogolo m'zovuta komanso kufunikira mwachangu kuchuluka kwa ma signals, ma PCB okhala ndi ma frequency apamwamba akhala gawo lofunikira kwambiri pakukula kwa ntchito yogwira ntchito kwambirism'magawo onse opanga zinthu.
Mafupipafupi apamwamba bolodi la dera losindikizidwaMa PCB (ma PCB) akhala ofunikira kwambiri popanga zamagetsi, zomwe zimapereka zinthu zosiyanasiyana zofunika. Mwachidule, ma PCB amphamvu kwambiri amatumiza bwino mafunde amagetsindi kutayika kochepa ndikuonetsetsa kuyenda kwa chizindikiro cha liwiro lalikuluMakhalidwe ofunikira okhudzana ndi ma PCB omwe amagwira ntchito pafupipafupi ndi awa:
Zochepa Chinthu Choyambitsa Kutaya MadziMa PCB okhala ndi ma frequency apamwamba nthawi zambiri amakhala ndi mphamvu yotaya mphamvu kuyambira 0.0019 mpaka 0.025, zomwe zimapangitsa kuti pakhale zochepa. kutayika kwa chizindikiro ndi kusamalira kuchuluka kwa ma signals.
Zochepa Dielectric Constant: Ma PCB awa ali ndi dielectric constant yotsika komanso yokhazikika, zomwe zimathandiza kuti ikhale yosalala kutumiza pafupipafupindi kuchepetsa kuchedwa kwa chizindikiro.
Kukana Mankhwala: Kuthekera kwa ma PCB amphamvu kwambiri kupirira kukhudzana ndi mankhwala n'kofunika kwambiri, zomwe zimapangitsa kuti asamavutike ndi dzimbiri komanso kuti akhale oyenera malo omwe ali ndi mankhwala ambiri.
Kunyowa Kochepa kwa Madzi: Popeza madzi salowa mwachangu, ma PCB okhala ndi ma frequency ambiri ndi oyenera kugwiritsidwa ntchito m'malo onyowa komanso amvula.
Zochepa Kukhazikika kwa Miyeso: Ma PCB amphamvu kwambiri amadziwika kuti amasunga kukula kwawo komanso sakhudzidwa ndi kusintha kwa kutentha kwa chilengedwe.
Popeza makhalidwe amenewa ndi ofala kwambiri, kugwiritsa ntchito kwawo n’kofala kwambiri. Komabe, opanga ma PCB ayenera kuonetsetsa kuti njira zotsatirazi zikutsatiridwa mosamala popanga ma PCB amphamvu kwambiri:
Dziwani PCB pafupipafupi chizindikiroNdikofunikira kwambiri kukhazikitsa zofunikira za magetsi ndi mphamvu, kugawa chilichonse ndege yamagetsis, ndikuwunika momwe zizindikiro zosiyanasiyana zimakhalira. Kuphatikiza apo, kuchepetsa kuchuluka kwa kulekerera ndi kuchepetsa kuchuluka kwa phokoso ndizofunikira kwambiri.
Kuyika bolodikukonzekera: Zofunikira pa gawo lokhazikikaziyenera kukonzedwa mosamala, poganizira zinthu zenizeni ndi zofooka zake.
Kukonzekera pansi: PCB iyenera kugawidwa m'magawo, ndipo kulekanitsidwa koyenera kusungidwa m'malo omwe ali ndi magawo a digito ndi analogi kuti apewe kusokoneza.
Mphamvu ndi ndege yapansis: Kapangidwe ka PCB kakafotokozedwa, kumvetsetsa dongosolo la pansi ndikofunikira. Kugawa malo apansi ndikofunikira, ndipo kuphatikiza choletsa pamodzi ndi chizindikiro kuti njira yobwerera ikhale yabwino ndikofunikira.
Chepetsani kukula kwa mapatani a nthaka: Ma PCB okhala ndi ma frequency ambiri nthawi zambiri amakhala ndi ma pad ang'onoang'ono. Kuchepetsa malo kumathandiza kuchepetsa mphamvu ya parasiticndipo imawonjezera mphamvu ya makina.
Njira chizindikiro cha pafupipafupis: Zizindikiro zama frequency apamwamba zimadziwika kuti zimapanga ma radiation ambiri. Kuyendetsa bwino ma frequency signal kumatha kuletsa kusokonezana pakati pa zizindikiro.
Gwiritsani ntchito lamulo la 3W: Kutsatira lamulo la 3W kumatsimikizira kuti umphumphu wa chizindikiro umasungidwa, zomwe zimapangitsa kusiyana pakati pa zizindikiro ndikuchepetsa mphamvu yolumikizirana.
Gwiritsani ntchito lamulo la 20H: Kulumikizana pakati pa ndege zapansi ndi zamagetsi kungayambitse chiwopsezo pa kapangidwe kanu. Lamulo la 20H limatsimikizira kuti makulidwe pakati pa ndege zapansi ndi zamagetsi zapafupi ndi apamwamba ndi akulu kuposa ndege yamagetsi.
Kugwiritsa Ntchito Ma PCB Othamanga Kwambiri
Kugwiritsa ntchito ma PCB amphamvu kwambiri kukuchulukirachulukira, ndipo ntchito zake zikuphatikizapo:
Machitidwe olumikizirana mu zida zosefera, chokulitsas, malo olimbikitsiras, ndi wolandilas.
Kugwiritsa ntchito zida zankhondo popanga zipolopolo ndi mfuti.
Dongosolo la radarzomwe zimatsogolera ndege ndikuletsa ngozi.
Zipangizo zofunikira kwambiri zowunikira ndi kuyang'anira matenda m'makampani azachipatala.
Pomaliza
Ma PCB okhala ndi ma frequency apamwamba ndi ofunikira kwambiri popanga ma PCB amagetsi, omwe amapereka zinthu zolimba zomwe zimawapangitsa kukhala chisankho chabwino kwambiri pazida zamagetsi. Amagwira ntchito yofunika kwambiri pakugwiritsa ntchito bwino kwambiri ndipo akuyembekezeka kukhala ofunikira kwambiri chifukwa cha zovuta zomwe zikukula zamagetsi komanso kufunikira kwa kutumiza ma signal mwachangu.
