Lihokelo tsa RF coaxial ke likarolo tsa bohlokoa bakeng sa -ho fetisoa ha mats'oao a mangata, 'me ho nepahala ha tšebetso ea tsona ho ama ka kotloloho boleng ba puisano ba sesebelisoa. Ho tloha ho khetho ea thepa e tala ho isa tekong ea ho qetela ea sehlahisoa, mohato o mong le o mong o hloka taolo e tiileng ea litekanyetso tsa tekheniki. Lintlha tse latelang li qaqisa ts'ebetso ea mantlha ea tlhahiso.
1. Tokisetso ea Boitsebiso le Phekolo Pele
Karolong ea pele ea tlhahiso, alloy ea koporo e phahameng{{0}e sebetsang hantle (joalo ka koporo ea beryllium kapa tin-phosphor bronze) e khethoa joalo ka thepa ea mantlha. Conductor ea ka ntle hangata e koahetsoe ka khauta kapa silevera ho fokotsa khanyetso ea ho kopana. Thepa ea insulating hangata ke polytetrafluoroethylene (PTFE) kapa ceramic-based composite 'me e tlameha ho omisoa sebakeng sa mocheso o sa fetoheng le mongobo ho netefatsa mongobo o ka tlase ho 0.05%. Likarolo tse ka sehloohong, tse kang ho ikopanya le setsi, li kena ka mokhoa o batang oa lihlooho. Sena se kenyelletsa ho hatakela molamu hore o be sebopehong sa cylindrical ka bophara bo itseng ka thae, ho rala motheo oa ts'ebetso e nepahetseng e latelang.
2. Precision Machining
Mokhanni oa setsi o siloa ho isa maemong a li-micron ka ho sebelisa lathe ea CNC, ho fihlela boima ba bokaholimo ba Ra0.2μm kapa ka tlase, ka mamello ea mantlha e bolokiloeng ka har'a ± 0.005mm. E ka ntle ea li-conductor housing e entsoe ka CNC ho etsa likhoele tse ka hare le li-grooves, ho sebelisoa lithulusi tsa carbide bakeng sa ho itšeha-ka lebelo le fetang 20,000 rpm. Tšehetso e sireletsang e bōptjoa ho sebelisoa mochine o entsoeng ka ente e nepahetseng, o nang le mocheso oa hlobo o laoloang hantle ka tekanyo ea 180±5 ho netefatsa hore ho tlatsoa ka mokhoa o ts'oanang oa PTFE cavity ntle le li-bubble tsa moea.
3. Kalafo ea Bokaholimo le Electroplating
Likarolo tsohle tsa tšepe li na le lipotoloho tse tharo tsa ho hloekisa ka matla ho tlosa oli le litšila, 'me li lateloe ke ho fokotsa khatello ea maikutlo ho felisa khatello ea kelello e setseng ho tloha machining. Ts'ebetso ea electroplating e sebelisa mohala oa tlhahiso o ikemetseng, ho qala ka seaparo sa botlaaseng ba nickel (botenya bo boholo ho feta kapa bo lekanang le 3μm), bo lateloa ke ho roala khauta (botenya ba 0.5-1.0μm) kapa ho pata ha silevera (botenya ba 5-8μm). Thempereichara ea ho hlapa e laoloa ka thata ho likhato tse 50±2, 'me boima ba hona joale bo bolokiloe ho 2-3A/dm². Lihokelo tse sebelisoang libakeng tse khethehileng le tsona li ka hloka passivation e eketsehileng kapa lera la conductive oxide.
4. Ts'ebetso ea Kopano ea Karolo
Mosebetsi oa ho kopanya o etsoa ka phaposing e hloekisitsoeng ea Sehlopha sa 100, 'me basebetsi ba lokela ho apara liaparo tse thibelang{1} Taba ea pele, insulator e petelitsoe hantle ka har'a groove ea sebaka sa bolulo, ka mocheso o nepahetseng oa ±1℃ha e sirelelitsoe ka sekhomaretsi se chesang{4} se qhibilihisang. Mokhanni oa setsi o tsamaisana le ts'ehetso ea ho kenya letsoho ho sebelisa ho kopana ha selemo, 'me ho sebelisoa laser alignment gauge ho hlahloba phoso ea coaxiality (Ka tlase kapa e lekanang le 0.01mm). Palo e nyane ea grease ea silicone e sebelisoa ho khokahanyo ea khoele ho fokotsa matla a ho kenya. Qetellong, ntlo e tiisitsoe ho sebelisoa mochine oa crimping o inehetseng, o nang le matla a crimping a laoloang ka har'a 50-80N.
5. Teko ea Ts'ebetso le Taolo ea Boleng
Sehlahisoa se phethiloeng se etsa tlhahlobo e felletseng ea tlhahlobo: VSWR (voltage stand wave ratio) e lekoa ka mohlahlobi oa marang-rang, ka tlhokahalo e ka tlase ho kapa e lekanang le 1.15 ka har'a sehlopha sa maqhubu a 20GHz. Ho hana ho kopana ho lekanyetsoa ka mokhoa o mene- oa terata, o nang le boleng bo tloaelehileng ba<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%.
Tlhahiso ea sehokelo sa RF ea sejoale-joale e kopantseng ka botebo tlhahiso e nepahetseng le mahlale a bohlale a tlhahlobo. Kenyelletso ea lits'ebetso tse tsoetseng pele joalo ka tlhahlobo ea pono ea mochini le tlhoekiso ea plasma e matlafatsa le ho feta ho tsitsisa le ho ts'epahala ha sehlahisoa. Ka nts'etsopele ea likhokahano tsa 5G le tekhenoloji ea millimeter-ea maqhubu, tlhokahalo ea lihokelo tse nyane le tse phahameng-e tsamaisa mekhoa ea tlhahiso ho ea ho nanometer{5}}ho nepahala ha boemo.
