Izixhumi ze-RF coaxial ziyizingxenye ezibalulekile-zokudlulisa isignali yemvamisa, futhi ukunemba kwezinqubo zazo zokukhiqiza kuthinta ngokuqondile ikhwalithi yokuxhumana yamathuluzi. Ukusuka ekukhethweni kwezinto ezingavuthiwe kuya ekuhlolweni komkhiqizo wokugcina, isinyathelo ngasinye sidinga ukulawula okuqinile kwemingcele yezobuchwepheshe. Imininingwane elandelayo ngenqubo yokukhiqiza ewumongo.
1. Ukulungiselela Impahla Nokwelashwa Kwangaphambili
Esigabeni sokuqala sokukhiqiza,-i-copper alloy esebenzayo ephezulu (efana ne-beryllium copper noma i-tin{1}}phosphor bronze) ikhethwa njengento eyinhloko. Ikhondakta yangaphandle ivamise ukugqitshwa ngegolide noma isiliva ukuze kuncishiswe ukumelana nokuxhumana. Izinto ezifaka insulating ngokuvamile ziyi-polytetrafluoroethylene (PTFE) noma izinhlanganisela ezisekelwe kwi-ceramic- futhi kufanele zomiswe endaweni yokushisa engashintshi kanye nomswakamo ukuze kuqinisekiswe okuqukethwe komswakama okungaphansi kuka-0.05%. Izingxenye ezibalulekile, njengokuthintana maphakathi, zithola inqubo yesihloko ebandayo. Lokhu kuhilela ukugxiviza induku ibe yisimo esiyisilinda esinobubanzi obuthile ngokusebenzisa idayisi, ukubeka isisekelo sokucutshungulwa okunembayo okulandelayo.
2. Precision Machining
Ikhondatha emaphakathi igaywa ibe kumazinga e-micron kusetshenziswa i-CNC lathe, ifinyelela ubulukhuni obuphezulu obungu-Ra0.2μm noma ngaphansi, ngokubekezelela okubalulekile kobukhulu okugcinwa ngaphakathi kuka-±0.005mm. Izindlu zamakhondatha angaphandle zigaywe yi-CNC ukuze kudaleke imicu yangaphakathi kanye nemigqa yokubeka indawo, kusetshenziswa amathuluzi e-carbide{3}}ukusika isivinini esiphezulu ngesivinini esingaphezu kuka-20,000 rpm. Ukwesekwa kwe-insulating kubunjwa kusetshenziswa umshini wokubumba umjovo onembile, onamazinga okushisa esikhunta alawulwa ngokunembile ku-180±5℃ukuze kuqinisekiswe ukugcwaliswa okufanayo komgodi we-PTFE ngaphandle kwamabhamuza omoya.
3. Ukwelashwa Okungaphezulu kanye Ne-Electroplating
Zonke izingxenye zensimbi zithola imijikelezo emithathu yokuhlanza nge-ultrasonic ukuze zisuse uwoyela nokungcola, okulandelwa ukuncishiswa kokunciphisa ukucindezeleka ukuze kuqedwe ukucindezeleka okusalayo emishinini. Inqubo ye-electroplating isebenzisa umugqa wokukhiqiza ozenzakalelayo, oqala ngejazi lesisekelo se-nickel (ukuqina Okukhulu noma okulingana no-3μm), kulandelwa ukucwecwa kwegolide (ubukhulu obungu-0.5-1.0μm) noma ukucwenga kwesiliva (ubukhulu obungu-5-8μm). Izinga lokushisa lokugeza lokucwenga lilawulwa ngokuqinile ku-50±2 degree, futhi ukuminyana kwamanje kugcinwa ku-2-3A/dm². Izixhumi ezizosetshenziswa ezindaweni ezikhethekile zingase futhi zidinge i-passivation eyengeziwe noma isendlalelo se-conductive oxide.
4. Inqubo Yomhlangano Wengxenye
Inqubo yokuhlanganisa iqhutshwa endaweni yokuhlanza Yekilasi Le-100, futhi opharetha kudingeka bagqoke{1}}izimpahla ezingashintshi. Okokuqala, isivikelo sicindezelwa ngokunembile endaweni yokuma yendlu, ngokunemba kwezinga lokushisa okungu-±1℃uma ivikelwe nge-adhesive encibilikayo eshisayo-. I-coaxiality emaphakathi iqondaniswe nokwesekwa kokufakwa kusetshenziswa okuthintwayo kwasentwasahlobo, futhi igeji yokuqondanisa kwe-laser isetshenziselwa ukuhlola iphutha le-coaxiality (Ngaphansi noma ilingana no-0.01mm). Inani elincane le-silicone grease lisetshenziswa ekuxhumekeni kwentambo ukuze kuncishiswe amandla okufaka. Okokugcina, indlu ivalwa kusetshenziswa umshini ozinikele wokufaka ama-crimping, onamandla okucindezela alawulwa ngaphakathi kwebanga elingu-50-80N.
5. Ukuhlolwa kokusebenza kanye nokulawulwa kwekhwalithi
Umkhiqizo oqediwe uba nenqubo yokuhlola ebanzi: I-VSWR (isilinganiso segagasi lokuma kwe-voltage) ihlolwa kusetshenziswa isihlaziyi senethiwekhi, ngemfuneko Engaphansi noma elingana no-1.15 ngaphakathi kwebhendi yefrikhwensi engu-20GHz. Ukumelana nokuxhumana kukalwa kusetshenziswa indlela-yezintambo ezine, ngenani elijwayelekile lokuthi<5mΩ. Durability testing includes checking contact wear after 500 plug-in and unplug cycles, and a 96-hour salt spray test to assess corrosion resistance. All data is recorded in real time through the MES system, keeping the defective rate below 0.3%.
Ukukhiqizwa kwesixhumi se-RF yesimanje kuhlanganise ngokujulile ukukhiqiza okunembayo nobuchwepheshe bokuhlola obuhlakaniphile. Ukwethulwa kwezinqubo ezithuthukisiwe ezifana nokuhlolwa kombono womshini kanye nokuhlanza i-plasma kuthuthukisa ngokwengeziwe ukuhambisana nokuthembeka komkhiqizo. Ngokuthuthukiswa kokuxhumana kwe-5G kanye nobuchwepheshe be-wave be-millimeter{3}}, isidingo sezixhumi ezincane neziphezulu{4}}zishayela izinqubo zokukhiqiza ekunembeni kweleveli ye-nanometer{5}}.
