Umuzenguruko wa SMD
Incamake
Icyakabiri, Ubuso bwa SMD bwububiko bufite imikorere myiza yo kwigunga.Barashobora gutandukanya neza ibimenyetso byohereza no kwakira, kwirinda kwivanga, no gukomeza ubudakemwa bwibimenyetso.Ubusumbane bwiyi mikorere yo kwigunga burashobora kwemeza imikorere ya sisitemu no kugabanya ibimenyetso byerekana.
Mubyongeyeho, SMD yubuso bwa Mount Circulator nayo ifite ubushyuhe buhebuje.Bashobora gukora hejuru yubushyuhe bugari, mubisanzwe bigera ku bushyuhe buri hagati ya -40 ° C na + 85 ° C, cyangwa bugari.Ubushyuhe butajegajega butuma SMD igaragara hejuru ya Circulator ikora neza mubidukikije.
Uburyo bwo gupakira uburyo bwa SMD bwubuso bwa Circulator nabwo bworoshe guhuza no gushiraho.Barashobora kwinjizamo ibikoresho byumuzingi kuri PCBs binyuze muburyo bwa tekinoroji, bidakenewe kwinjiza pin gakondo cyangwa uburyo bwo kugurisha.Ubu buryo bwo gupakira hejuru yububiko ntabwo butezimbere umusaruro gusa, ahubwo binafasha guhuza ubucucike buri hejuru, bityo bikabika umwanya no koroshya igishushanyo cya sisitemu.
Mubyongeyeho, SMD yubuso bwimisozi izenguruka ifite porogaramu nini muri sisitemu yitumanaho ryihuse hamwe nibikoresho bya microwave.Birashobora gukoreshwa mugutandukanya ibimenyetso hagati ya amplifier ya RF na antene, kunoza imikorere ya sisitemu no gutuza.Byongeye kandi, SMD yubuso bwa Mount Circulator irashobora kandi gukoreshwa mubikoresho bidafite umugozi, nkitumanaho ridafite insinga, sisitemu ya radar, hamwe n’itumanaho rya satelite, kugirango bikemure ibimenyetso byihuta byo kwiherera no gutandukana.
Muncamake, Ubuso bwa SMD bwububiko ni ibintu byoroshye, biremereye, kandi byoroshye gushyiramo igikoresho kimeze nkimpeta ifite umurongo mugari wa bande, imikorere myiza yo kwigunga, hamwe nubushyuhe bukabije.Bafite porogaramu zingenzi mubice nka sisitemu yo gutumanaho inshuro nyinshi, ibikoresho bya microwave, nibikoresho bya radio.Hamwe niterambere ridahwema ryikoranabuhanga, SMD yubuso bwa Mount Circulator izagira uruhare runini mubice byinshi kandi igire uruhare mugutezimbere ikoranabuhanga rigezweho.
Ikwirakwizwa rya RF Surface Mount Technology (RF SMT) ni ubwoko bwihariye bwibikoresho bya RF bikoreshwa mugucunga no gucunga ibimenyetso byinjira muri sisitemu ya RF.Ihame ryakazi ryayo rishingiye ku kuzenguruka kwa Faraday hamwe na magnetiki resonance yibintu muri electronique.Ikintu nyamukuru kiranga iki gikoresho nukwemerera ibimenyetso mubyerekezo runaka kunyuramo mugihe uhagarika ibimenyetso muburyo bunyuranye.
Umuzenguruko wa RF SMT ugizwe nibyambu bitatu, kimwekimwe cyose gishobora kuba nk'icyinjira cyangwa gisohoka.Iyo ikimenyetso cyinjiye ku cyambu, kiba cyerekejwe ku cyambu gikurikiraho hanyuma kigasohoka kiva ku cyambu cya gatatu.Icyerekezo cyo gutembera kwiki kimenyetso mubisanzwe ni isaha cyangwa isaha yo kugana.Niba ikimenyetso kigerageza gukwirakwiza muburyo butunguranye, umuzenguruko azahagarika cyangwa akuramo ibimenyetso kugirango yirinde kwivanga nibindi bice bya sisitemu uhereye kubimenyetso byinyuma.
Ibyiza byingenzi byumuzunguruko wa RF SMT ni miniaturizasi yabo no kwishyira hamwe kwinshi.Bitewe no gukoresha tekinoroji yubuso bwububiko, uyu muzingi urashobora gushyirwaho muburyo butaziguye kumuzunguruko utabanje gukenera insinga zihuza cyangwa umuhuza.Ibi ntibigabanya gusa ingano nuburemere bwibikoresho, ahubwo binoroshya uburyo bwo kwishyiriraho no kubungabunga.Mubyongeyeho, kubera igishushanyo mbonera cyacyo, RF SMT izenguruka mubisanzwe ifite imikorere myiza kandi yizewe.
Mubikorwa bifatika, abakwirakwiza RF SMT bafite uruhare runini muri sisitemu nyinshi za RF.Kurugero, muri sisitemu ya radar, irashobora gukumira ibimenyetso bya echo byinjira byinjira, bityo bikarinda ibyangiritse.Muri sisitemu yitumanaho, irashobora gukoreshwa mugutandukanya antenne yohereza no kwakira antenne kugirango wirinde ibimenyetso byinjira byinjira mubakira.Mubyongeyeho, kubera miniaturizasi yayo no kwishyira hamwe kwinshi, umuzenguruko wa RF SMT ukoreshwa cyane mubice nkimodoka zitagira abapilote hamwe n’itumanaho rya satelite.
Ariko, gushushanya no gukora RF SMT izenguruka nayo ihura nibibazo bimwe.Ubwa mbere, nkuko ihame ryakazi ririmo ibitekerezo bya electromagnetic bigoye, gushushanya no gutezimbere umuzenguruko bisaba ubumenyi bwumwuga.Icya kabiri, kubera ikoreshwa rya tekinoroji yo hejuru yubuso, inzira yo gukora umuzenguruko isaba ibikoresho byuzuye kandi bigenzurwa neza.Hanyuma, nkuko buri cyambu cyumuzenguruko gikeneye guhuza neza numurongo wikimenyetso gitunganywa, kugerageza no gukuramo umuzenguruko nabyo bisaba ibikoresho byubuhanga nubuhanga.
