1, Kev xaiv cov khoom siv: cov qauv kev ua haujlwm nruj
Lub siab - zaus thiab siab - teb ceev yuav tsum muaj hluav taws xob ua tau zoo ntawm cov khoom siv. Lub rooj tsav xwm luam tawm hauv 5G kev sib txuas lus thiab radar tshuab yuav tsum siv cov dielectric tsis tu ncua thiab tsis tshua muaj dielectric poob tangent cov ntaub ntawv xws li polytetrafluoroethylene thiab Rogers, los tswj cov teeb liab kis tsis tau qis dua 0.2dB / inchand muaj thermal stability. Cov cuab yeej siv hluav taws xob siab cia siab rau cov khoom siv hlau raws li cov khoom sib xyaw ua kom sov, xws li txhuas raws li cov ntawv luam tawm Circuit Court boards hauv lub tsheb tshiab BMS, uas muaj thermal conductivity ntau dua li cov phaj zoo tib yam thiab tuaj yeem ua cua sov sai, ua kom ruaj khov ntawm cov khoom siv. Cov ntawv thov tshwj xeeb ib puag ncig xws li aerospace thiab kev cog qoob loo kho mob xav tau cov ntaub ntawv los tiv thaiv qhov kub thiab txias. Polyimide cov ntaub ntawv nyiam vim lawv lub peev xwm ua haujlwm ntawm qhov kub ntawm -200℃txog 260℃thiab lawv cov hluav taws xob tiv thaiv. Hauv qee qhov xwm txheej, cov txheej txheem tshwj xeeb yuav tsum tau txhim kho kev tiv thaiv.
2, Tsim qhov raug: siab ceev thiab siab sib xws
Miniaturization tsav txoj kev loj hlob ntawm lub rooj tsav xwm luam tawm mus rau siab - kev sib txuas ceev ceev. Txoj kab dav / qhov sib nrug ntawm siab-kawg smartphone motherboards tau raug txo kom qis dua 10 μ m, thiab ntau qhov micro qhov thiab qhov qhov muag tsis pom kev thev naus laus zis tau siv los txhim kho kev sib txuas xov tooj. Kev kub ceev teeb liab kis tau tus mob yuav tsum tau siab -kev tswj impedance. Piv txwv li, tus yam ntxwv impedance ntawm USB 3.0 interface Circuit Court yuav tsum raug rau 50 Ω ± 5%. Thaum tsim qauv, qhov ntsuas qhov ntsuas hluav taws xob thiab cov yam ntxwv ntawm lub rooj tsavxwm yuav tsum tau txiav txim siab. Cov tshuab hluav taws xob tsis yooj yim muaj cov kev cai nruj rau lub zog thiab kev tsim hauv av. Kev ua tau zoo ntawm cov neeg rau zaub mov motherboards yuav tsum muab lub zog ruaj khov rau ntau yam khoom, txo cov suab nrov cuam tshuam los ntawm ntau- txheej txheej fais fab txheej thiab txheej txheej npaj, thiab ua tau raws li cov kev xav tau ntawm electromagnetic compatibility.
3, tsim cov txheej txheem: sib npaug ntawm qhov siab precision thiab ruaj khov
Ultra precision drilling yog qhov tseem ceeb rau kev ua micro qhov. Rau qhov apertures qis dua 0.15mm, laser drilling muaj qhov tseeb qhov chaw ntawm ± 15 μ m, tab sis kev tswj xyuas meej yog yuav tsum tau ua kom tsis txhob muaj qhov tsis xws ntawm phab ntsa, thiab qhov kev sib raug zoo ntawm cov txheej txheem ntau - txheej boards yuav tsum tau tswj nyob rau hauv 10% ntawm qhov aperture. Fine line etching siv photolithography technology los tsim corrosion-cov qauv resistant, nruj me ntsis tswj cov etching tov tsis thiab ua kom cov kab dav kam rau ua nyob rau hauv ± 5 μ m. Cov txheej txheem laminating txiav txim siab qhov zoo ntawm ntau- txheej boards, xav tau kev tswj xyuas qhov kub thiab txias nkhaus, xaiv cov nplooj ntawv uas tsim nyog, thiab siv cov cuab yeej siv qib siab los tiv thaiv delamination thiab zawv zawg. Ntxiv nrog rau kev ua kom tau raws li qhov yuav tsum tau ua ntawm weldability, kev kho saum npoo kuj yuav tsum tau hloov mus rau qhov chaw tshwj xeeb, xws li siv tshuaj lom neeg nickel plating los txhim kho corrosion tsis kam rau cov khoom siv marine luam tawm Circuit Board.
4, Kev tshuaj ntsuam xyuas zoo: kev ua kom tiav thiab nruj heev
Kev nyuaj siab tshwj xeeb cov ntawv luam tawm Circuit Court boards yuav tsum tau siab -cov cuab yeej kuaj xyuas qhov tseeb, nrog cov teeb meem ntawm electron beam nrhiav tau txog qib nanometer, uas tuaj yeem kuaj xyuas qhov teeb meem me me; X-Kev kuaj kab hluav taws xob tuaj yeem tsis cuam tshuam cov qauv sab hauv ntawm ntau- txheej boards. Kev ntsuam xyuas kev ntseeg tau npog cov kev ntsuam xyuas ib puag ncig ib puag ncig xws li kev kub siab thiab kev vibration, nrog rau kev sim tshwj xeeb rau ntau qhov chaw, xws li siab - qhov ntsuas hluav taws xob siab hauv aerospace thiab biocompatibility kuaj rau kev cog qoob loo. Nyob rau tib lub sijhawm, cov txheej txheem traceability tau sau tag nrho cov txheej txheem cov ntaub ntawv los ntawm cov ntaub ntawv raw mus rau cov khoom xa tuaj, ua kom yooj yim rau kev taug qab ntawm cov teeb meem zoo thiab cov txheej txheem optimization,
