[Abstract] Kulesi sigaba, ukuze kuqinisekiswe ukuhlanganiswa nokuhlanganiswa okuphezulu kwemisebenzi kagesi wemoto, futhi kuhlangatshezwane nokuthuthukiswa kwesakhiwo esisha esihlakaniphile sikagesi, isixhumi esibonakalayo esikhethwa ngokuvamile sinezinga eliphezulu lokuhlanganiswa (hhayi nje ukudlulisa okuphezulu. ukunikezwa kwamandla kwamanje nokuphezulu, kodwa futhi nokudlulisa amasiginali e-analog aphansi futhi aphansi), khetha amazinga ahlukene ezakhiwo zokuxhuma zemisebenzi ehlukene kanye nezikhundla ezahlukene ukuze uqinisekise ukuthi impilo yesevisi yesixhumi akufanele ibe ngaphansi kunempilo yesevisi. zezimoto ezijwayelekile, ngaphakathi kwebanga elivumelekile lamaphutha Ukudluliswa okuzinzile kokuphakelwa kukagesi namasignali okulawula kufanele kuqinisekiswe;izixhumi zixhunywe ngokusebenzisa ama-terminals, futhi amatheminali owesilisa nowesifazane ayenziwe ngezinto zensimbi zokuqhuba.Izinga lokuxhuma kwetheminali lithinta ngqo ukuthembeka kwemisebenzi kagesi yemoto.
1 Isingeniso
Amatheminali ezintambo zokudlulisela kwamanje kuzixhumi zezintambo zemoto ngokuvamile agxivizwa kusuka kumaalloyi ethusi ekhwalithi ephezulu.Ingxenye eyodwa yamatheminali kufanele iboshelwe egobolondweni lepulasitiki, kanti enye ingxenye kufanele ixhunywe ngogesi kumatheminali okukhwelana.I-alloy yethusi Nakuba inezici ezinhle zemishini, ukusebenza kwayo ku-conductivity kagesi akwenelisi; Ngokuvamile, izinto ezisebenza kahle zikagesi zinezakhiwo ezijwayelekile zemishini, njenge-tin, igolide, isiliva, nokunye okunjalo.Ngakho-ke, i-plating iyadingeka kakhulu ukunikeza amatheminali nge-conductivity kagesi eyamukelekayo kanye nezakhiwo zemishini ngesikhathi esifanayo.
2 Izinhlobo Zokucwenga
Ngenxa yemisebenzi ehlukene yamatheminali kanye nezindawo ezihlukene zokusebenzisa (izinga lokushisa eliphezulu, umjikelezo oshisayo, umswakama, ukushaqeka, ukudlidliza, uthuli, njll.), i-terminal plating ekhethiwe nayo iyahlukahluka, imvamisa ngokusebenzisa izinga lokushisa eliphezulu eliqhubekayo, ukujiya kwe-plating, izindleko, ukumatanisa Ungqimba olufanele lokunamathisela lwetheminali yokukhwelana iwukukhetha amatheminali anezingqimba ezihlukene zokucwenga ukuhlangabezana nokuzinza komsebenzi kagesi.
3 Ukuqhathaniswa kwama-Coatings
3.1 Amatheminali afakwe ngothayela
I-tin plating ngokuvamile inokusimama okuhle kwemvelo kanye nezindleko eziphansi, ngakho-ke isetshenziswa kakhulu, futhi kunezingqimba eziningi zokucwenga zikathayela ezisetshenziswa ezicini ezihlukene, njengethani elimnyama, ithini elikhanyayo, ne-dip tin eshisayo.Uma kuqhathaniswa nezinye izigqoko, ukumelana nokugqokwa kubi, imijikelezo yokukhwelana engaphansi kwe-10, futhi ukusebenza kokuxhumana kuzokwehla ngokuhamba kwesikhathi namazinga okushisa, futhi ngokuvamile kusetshenziswa ezimweni ezingaphansi kuka-125 °C.Lapho uklama amatheminali ane-tin-plated, amandla okuxhumana aphezulu kanye nokufuduka okuncane kufanele kucatshangelwe ukuze kuqinisekiswe ukuzinza kothintana naye.
3.2 Amatheminali aneSiliva
I-Silver plating ngokuvamile inokusebenza okuhle kwephuzu lokuxhumana, ingasetshenziswa ngokuqhubekayo ku-150 ° C, izindleko zibiza kakhulu, kulula ukugqwala emoyeni lapho kukhona isulfure ne-chlorine, eqinile kune-tin plating, futhi ukumelana kwayo kuncane. iphakeme noma ilingana ne-tin , into engase ibe khona ye-electromigration iholela kalula kuzingozi ezingaba khona kusixhumi.
3.3 Amatheminali agqitshwe ngegolide
Amatheminali afakwe ngegolide anokusebenza okuhle kokuxhumana nokuzinza kwemvelo, izinga lokushisa eliqhubekayo lingadlula i-125 ℃, futhi linokumelana okuhle kakhulu nokungqubuzana.Igolide eliqinile liqinile kunethayela nesiliva, futhi linokumelana okuhle kakhulu nokungqubuzana, kodwa izindleko zalo ziphakeme, futhi akuwona wonke amatheminali adinga ucwecwe lwegolide.Uma amandla okuthintana ephansi futhi ungqimba lwe-tin plating lugqokile, esikhundleni segolide kungasetshenziswa.Isikhumulo.
4 Ukubaluleka Kokufakwa Kwesicelo Sokufakwa Kwamatheminali
Akukwazi ukunciphisa kuphela ukugqwala kwendawo yezinto ezigcinayo, kodwa futhi kuthuthukise isimo samandla okufaka.
4.1 Yehlisa ukungqubuzana futhi unciphise amandla okufaka
Izinto eziyinhloko ezithinta i-coefficient yokungqubuzana phakathi kwamatheminali zifaka: impahla, ukuhwashala komhlaba, nokuphathwa kwendawo.Lapho impahla yetheminali ilungisiwe, i-coefficient yokungqubuzana phakathi kwamatheminali iyaqiniswa, futhi ubuhholo obuhlobene bukhulu ngokuqhathaniswa.Lapho ingaphezulu letheminali liphathwa nge-coefficient, izinto zokumboza, ukujiya koqweqwe lwawo, kanye nokuqedwa kokuhlanganisa kunomthelela omuhle ku-coefficient yokungqubuzana.
4.2 Vimbela i-oxidation kanye nokugqwala ngemva kokulimala kwe-terminal plating
Phakathi nezikhathi ezingu-10 ezisebenzayo zokuxhuma nokukhipha ama-plug, amatheminali ayasebenzisana ngokulingana kokuphazamiseka.Uma kunengcindezi yokuxhumana, ukugudluka okuhlobene phakathi kwamatheminali owesilisa nowesifazane kuzolimaza i-plating endaweni yetheminali noma kuklwebhe kancane ngesikhathi sokunyakaza.Imikhondo iholela ekushubeni okungalingani noma ngisho nokuchayeka kwengubo, okuholela ekushintsheni kwesakhiwo semishini, imihuzuko, ukunamathela, imfucumfucu egugile, ukudluliswa kwempahla, njll., kanye nokukhiqizwa kokushisa. Izikhathi eziningi zokuxhuma nokukhipha i-plug, kusobala kakhulu izimpawu zokuklwebheka ebusweni betheminali.Ngaphansi kwesenzo somsebenzi wesikhathi eside kanye nemvelo yangaphandle, ukuphela kulula kakhulu ukuhluleka.Ngokuyinhloko kungenxa yokugqwala kwe-oxidative okubangelwa ukunyakaza okuncane okuhlobene kwendawo yokuxhumana, ngokuvamile ukunyakaza okuhlobene kwe-10 ~ 100μm;ukunyakaza okunodlame kungase kubangele ukuguga okuyingozi phakathi kwezindawo ezithintana naye, ukudlidliza okuncane kungase kubangele ukugqwala kokungqubuzana, ukushaqeka okushisayo kanye nemithelela yemvelo kusheshisa inqubo.
5 Isiphetho
Ukwengeza ungqimba lwe-plating kutheminali akukwazi nje ukunciphisa ukugqwala okungaphezulu kwe-terminal material, kodwa futhi kuthuthukise isimo samandla okufaka.Kodwa-ke, ukuze kwandiswe umsebenzi nomnotho, isendlalelo se-plating ngokuyinhloko sibhekisela ezimweni ezilandelayo zokusetshenziswa: singamelana nezimo zangempela zokushisa ze-terminal;ukuvikelwa kwemvelo , okungagqwali;uzinzile kumakhemikhali;ukuthintana okuqinisekisiwe;ukunciphisa ukungqubuzana kanye ne-insulation yokugqoka;izindleko eziphansi.Njengoba indawo kagesi yemoto yonke iba inkimbinkimbi futhi isikhathi esisha samandla siyeza, kuphela ngokuhlola njalo ubuchwepheshe bokukhiqiza izingxenye nezingxenye lapho ukuphindaphinda okusheshayo kwemisebenzi emisha kungahlangatshezwana nayo.
