IV. Umhlahlandlela Wokukhetha Izinto Ezinembile Zama-Terminals Ezimweni Zokusetshenziswa Ezihlukahlukene
Yakha izindlela zokukhetha ezijwayelekile embonini ngokusekelwe ekuhlanganisweni kwezinto eziyisisekelo kanye nokuqeda ukubopha ukuze kusetshenziswe kalula endaweni:
1. Izinto zikagesi zabathengi ezijwayelekile kanye nezinto zasekhaya (Izinga lokushisa eliphakathi, imijikelezo ephansi yokuhlangana, ukusetshenziswa endlini)
Inketho Ekhethwayo: Ithusi / I-Phosphor Ithusi + I-Tin Plating
Isilinganiso esihle kakhulu sezindleko nokusebenza, esihlangabezana ngokugcwele nezidingo zokusebenza ezijwayelekile ngaphandle kokuchitha isikhathi esiningi.
2. Ukulawulwa Kwezimboni kanye Nekhaya Elihlakaniphile (Imijikelezo Yokuhlangana Ephakathi, Ukudlidliza Okuncane)
Inketho Ekhethwayo: I-Phosphor Bronze + I-Heavy Tin Plating / I-Thin Gold Plating
Ilinganisela impilo yesevisi kanye nokuzinza, ifanele ukusetshenziswa kwezimboni okunamandla isikhathi eside nokudlidliza kancane kanye nempahla ethuthukisiwe yokulwa nokuguga.
3. Imishini Yezimoto (-40℃ ~ 125℃ Ububanzi Bokushisa Obubanzi, Ukudlidliza Okuqhubekayo)
Inketho Ekhethwayo: I-Phosphor Bronze / i-Beryllium Copper + i-Gold Plating
Izinhlelo zokusebenza zezimoto zinokushintshashintsha okukhulu kwezinga lokushisa kanye nokudlidliza okuqhubekayo. Izinto eziyisisekelo ezinwebeka kakhulu ezihlanganiswe ne-oxidation-resistant gold plating ziyimpoqo ukuvimbela ukuthintana okuxekethile kanye nokuphazamiseka kwesignali.
4. Imishini Yezokwelapha Eqondile, Ezokuxhumana kanye Nezindiza (Ukuthembeka Okuphezulu, Ukudluliselwa Kwesignali Evame Kakhulu)
Inketho Ekhethwayo: I-Beryllium Copper + I-Gluten Gold Plating
Inezici zokumelana nokuxhumana ezizinzile kakhulu, ukumelana nokukhathala okuhle kakhulu kanye nokubekezelelana kwemvelo okuphezulu, isusa ukuphazamiseka kwesignali kanye namaphutha okuxhumana kwemishini enembile.
Isixhumi samandla aphezulu se-AMASS sisebenzisa itheminali engakusiza ukuthi ugcine ukuxhumana okuzinzile ezimweni zohlelo lokusebenza njengokudlidliza kwamandla aphezulu, imiphumela ephindaphindwayo yokushisa okuphezulu nokuphansi, ivolumu encane, kanye namandla aphezulu.
