RF coaxial haši su ne mabuɗin abubuwan haɗin kai don haɓakar watsa siginar mita mai girma{0}, kuma daidaitaccen tsarin samar da su yana tasiri kai tsaye ingancin sadarwa na kayan aiki. Daga zaɓin ɗanyen abu zuwa gwajin samfur na ƙarshe, kowane mataki yana buƙatar kulawa da sigogi na fasaha. Wadannan cikakkun bayanai game da ainihin tsarin samarwa.
1. Shirye-shiryen Kayayyaki da Magani
A farkon samarwa, an zaɓi babban gawa na jan ƙarfe (kamar beryllium jan ƙarfe ko dala) a matsayin babban abu. Ana lulluɓe madugu na waje da zinari ko azurfa don rage juriyar lamba. Abubuwan da ke rufewa galibi polytetrafluoroethylene (PTFE) ne ko yumbu{4} tushen abubuwan da aka haɗa kuma dole ne a bushe su a cikin yanayin zafi da zafi akai-akai don tabbatar da ɗanɗanon abun ciki ƙasa da 0.05%. Maɓallai maɓallai, kamar cibiyar sadarwa, suna aiwatar da tsarin taken sanyi. Wannan ya haɗa da buga sandar zuwa siffa ta silindi mai takamaiman diamita ta hanyar mutu, aza harsashin sarrafa daidaitaccen aiki na gaba.
2. Daidaitaccen Machining
Ana niƙa mai gudanar da cibiyar zuwa matakan micron ta amfani da lathe CNC, yana samun ƙarancin ƙasa na Ra0.2μm ko ƙasa da haka, tare da jure juzu'i na maɓalli a tsakanin ± 0.005mm. Gidajen madugu na waje ana niƙa CNC don ƙirƙirar zaren ciki da madaidaicin ragi, ta amfani da kayan aikin carbide don yanke saurin gudu fiye da 20,000 rpm. An ƙera goyan bayan insulating ta amfani da ingantacciyar injin gyare-gyaren allura, tare da yanayin zafi daidai ana sarrafa shi a digiri 180 ± 5 don tabbatar da ciko iri ɗaya na kogon PTFE ba tare da kumfa mai iska ba.
3. Surface Jiyya da Electroplating
Duk sassa na ƙarfe suna jujjuya zagayowar tsaftacewa na ultrasonic guda uku don cire mai da gurɓataccen abu, sannan kuma annealing taimako na danniya don kawar da saura damuwa daga machining. Tsarin lantarki yana amfani da layin samarwa mai sarrafa kansa, yana farawa da gashin nickel (ƙauri mafi girma ko daidai da 3μm), sannan plating na zinari (ƙauri 0.5-1.0μm) ko plating na azurfa (kauri 5-8μm). The plating bath zafin jiki ne tsananin sarrafawa a 50± 2 digiri , kuma halin yanzu yawa ana kiyaye a 2-3A/dm². Masu haɗin haɗin don amfani a wurare na musamman na iya buƙatar ƙarin wucewa ko Layer oxide.
4.Tsarin Haɗuwa da Sashe
Ana gudanar da tsarin taron ne a cikin ɗaki mai tsabta na Class 100, kuma ana buƙatar masu aiki su sanya rigar da ba ta dace ba. Na farko, ana matse insulator daidai a cikin madaidaicin matsugunin gidaje, tare da daidaiton zafin jiki na ±1 digiri lokacin da aka amintar da shi tare da manne mai zafi{4}} narke. Mai gudanarwa na tsakiya yana daidaitawa tare da tallafin rufewa ta amfani da lamba ta bazara, kuma ana amfani da ma'aunin daidaitawar laser don bincika kuskuren coaxiality (Ƙasa da ko daidai da 0.01mm). Ana amfani da ƙaramin adadin man shafawa na silicone zuwa haɗin da aka zare don rage ƙarfin sakawa. A ƙarshe, an rufe gidan ta hanyar amfani da na'urar da aka keɓe, tare da ƙarfin da aka sarrafa a cikin kewayon 50-80N.
5. Gwajin Aiki da Kula da inganci
Samfurin da aka gama yana ɗaukar cikakken tsari na dubawa: VSWR (raɗin igiyar wutar lantarki) ana gwada ta ta amfani da mai nazarin hanyar sadarwa, tare da buƙatar ƙasa da ko daidai da 1.15 a cikin rukunin mitar 20GHz. Ana auna juriyar tuntuɓar ta amfani da hanyar waya guda huɗu{3}, tare da madaidaicin ƙimar<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%.
Samar da haɗin haɗin RF na zamani ya haɗu da haɓaka daidaitaccen masana'anta tare da fasahar bincike mai hankali. Gabatar da matakai na ci gaba kamar duba hangen nesa na injin da tsaftacewar plasma yana kara haɓaka daidaiton samfur da amincin. Tare da haɓaka hanyoyin sadarwa na 5G da fasahar milimita{3}}wararrun igiyar ruwa, buƙatun ƙarami da manyan haɗe-haɗe{4}}yawawan haɗe-haɗe yana haifar da hanyoyin samarwa zuwa nanometer{5}madaidaicin matakin.
