1. Fɛnw labɛnni ani u furakɛli ka kɔn
A dilanni daminɛ na, nɛgɛdaga dɔ min bɛ se ka fɛnw ta kosɛbɛ (i n’a fɔ beriliyɔmu nɛgɛ walima tintin-fosifɔri nɛgɛso) bɛ sugandi ka kɛ fɛnba ye. A ka c’a la, kɛnɛma-minɛn bɛ kɛ ni sanu walima warijɛ ye walasa ka dɔ bɔ a ka ɲɔgɔn sɔrɔli la. A ka c’a la, fɛn min bɛ kɛ ka fɛnw tanga, o ye politetarafluoroetilɛni (PTFE) walima seramiki-fɛnw ye minnu dilannen don ni seramiki-fɛnw ye, wa u ka kan ka ja yɔrɔ la min bɛ funteni ni nɛnɛ tuma bɛɛ walasa ji hakɛ ka se 0,05% ma. Fɛn kolomaw, i n’a fɔ santiri ɲɔgɔnye, olu bɛ kɛ ni nɛnɛ kuncɛcogo ye. O ye ka bere in taamasiyɛn ka kɛ silinda ye ni a cɛmancɛ kɛrɛnkɛrɛnnen ye ka tɛmɛ die fɛ, ka jusigilan sigi walasa ka baara kɛ ni a ye cogo tigitigi la kɔfɛ.
2. Masina kɛcogo tigitigi
Santiri ɲɛminɛbaga bɛ sɔgɔ fo ka se mikron hakɛ ma ni CNC tour ye, ka se ka sanfɛla gɛlɛya sɔrɔ Ra0,2μm walima a dɔgɔyalenba la, ni muɲuli kunbabaw ye minnu bɛ mara ±0,005mm kɔnɔ. Kɛnɛma ɲɛminɛbaga so bɛ CNC sɔgɔ walasa ka kɔnɔna jiriw ni jɔyɔrɔfalanw dilan, ka baara kɛ ni karɔbɔli baarakɛminɛnw ye walasa ka tigɛ teliya la-teliya la min bɛ tɛmɛ 20.000 kan rpm. Insulating support bɛ dilan ni pikirikɛlan tigitigi ye, ni moulu funteni bɛ kɔlɔsi tigitigi degere 180±5 la walasa ka PTFE kɔnɔna fa cogo kelen na ni fiɲɛ tɛ a la.
3. Surface furakɛli ani kuran sɛnɛcogo
Nɛgɛ yɔrɔw bɛɛ bɛ saniya siɲɛ saba kɛ ni ultrasonic ye walasa ka tulu ni nɔgɔw bɔ, o kɔfɛ, degunw lajɔli bɛ kɛ walasa ka degun tolenw bɔ masinw na. Kuranko kɛcogo bɛ baara kɛ ni otomatiki fɛn dilanni sira ye, k’a daminɛ ni nikɛri basigilen ye (a janya ka bon walima a bɛ bɛn 3μm ma), o kɔfɛ sanu sɔgɔli (a janya ye 0,5-1,0μm ye) walima warijɛ sɔgɔli (a janya ye 5-8μm ye). Plating bath funteni bɛ kɔlɔsi kosɛbɛ 50±2℃, ani sisan density bɛ mara 2-3A/dm2 la. Jɛɲɔgɔnya minnu bɛ kɛ sigida kɛrɛnkɛrɛnnenw na, olu fana bɛ se ka kɛ sababu ye ka pasifasiyɔn wɛrɛw walima ɔkisizɛni jiginni kɛ.
4. Kɔnɔnafiliw lajɛcogo
Lajɛ baara bɛ kɛ san 100 sanuyaso kɔnɔ, wa baarakɛlaw wajibiyalen don ka finiw don minnu tɛ-static. Fɔlɔ, insulator bɛ digi tigitigi ka don so jɔyɔrɔ la, ni funteni hakɛ bɛ se ka kɛ ±1 ye ni a sirilen don ni nɔrɔlan funteniman-melt ye. Cɛmancɛ ɲɛminɛbaga bɛ bɛn ni insulasi dɛmɛnan ye ni resɔn contact ye, ani laser alignment gauge bɛ kɛ ka coaxiality fili lajɛ (<=0.01mm). Silikoni tulu dɔɔni bɛ kɛ jiribolo la walasa ka dɔ bɔ a doncogo fanga la. A laban na, so bɛ datugu ni crimping machine kɛrɛnkɛrɛnnen ye, ni crimping force ye min bɛ kɔlɔsi 50-80N kɔnɔ.
5. Baarakɛcogo sɛgɛsɛgɛli ani jogoɲini
Fɛn dilannen bɛ sɛgɛsɛgɛli kɛcogo bɛɛ lajɛlen kɛ : VSWR (voltage standing wave ratio) bɛ kɔrɔbɔ ni rezow sɛgɛsɛgɛlikɛlan ye, ni wajibi ye min ka dɔgɔ ni 1,15 ye walima min bɛ bɛn 1,15 ma 20GHz frequency band kɔnɔ. Kontakt resistance bɛ suman ni naani-wire fɛɛrɛ ye, ni standard value ye<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%.
