Los ntawm kev siv dav dav ntawm cov cuab yeej ntse mus rau qhov sib sib zog nqus hloov pauv ntawm kev lag luam automation, kev ua haujlwm ntawm 5G kev sib txuas lus boards, raws li cov tub ntxhais cov khoom siv ntawm 5G thev naus laus zis, cuam tshuam ncaj qha rau kev ua haujlwm thiab kev ruaj ntseg ntawm tag nrho cov kev sib txuas lus. Tus yuam sij rau kev ua tau zoo ntawm 5G kev sib txuas lus boards feem ntau nyob ntawm cov khoom xaiv. Cov ntaub ntawv tsim nyog yuav tsum tsis yog tsuas yog ua tau raws li cov kev cai ntawm kev siv ntau zaus, kev kub ceev, thiab qis latency rau 5G kev sib txuas lus, tab sis kuj muaj kev ruaj ntseg zoo, kev cia siab, thiab kev hloov mus rau cov xwm txheej sib txawv.
Copper clad laminate: lub hauv paus ntawm cov teeb liab kis tau tus mob
Copper clad laminate plays lub luag haujlwm tseem ceeb hauv cov teeb liab kis tau tus mob hauv 5G kev sib txuas lus boards thiab yog cov khoom siv tseem ceeb hauv kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob hauv Circuit Court. Nrog rau kev txhim kho ntawm 5G kev sib txuas lus cov khoom lag luam mus rau qhov me me thiab muaj peev xwm loj, cov kev cai nruj tau muab tso rau pem hauv ntej rau kev ua haujlwm ntawm tooj liab- clad laminates ntawm ntau zaus thiab nrawm, uas cov tsoos tooj liab- clad laminates tsis tuaj yeem ua tau raws li. Nyob rau hauv cov ntsiab lus no, polytetrafluoroethylene raws high- zaus tooj liab- clad laminates tau dhau los ua cov khoom tseem ceeb nyob rau hauv lub caij nyoog ntawm kev kub ceev thiab kev kub ceev. Cov khoom no muaj cov yam ntxwv xws li tsis tshua muaj dielectric tsis tu ncua thiab tsis tshua muaj dielectric poob, uas tuaj yeem ua kom lub teeb liab nthuav tawm sai thiab tsis muaj kev cuam tshuam thaum sib kis.
Tshwj xeeb cob thiab fiberglass daim ntaub: txhim khu kev ua tau zoo ntawm lub rooj tsavxwm
FR-4, ib qho epoxy substrate reinforced nrog fiberglass daim ntaub, yog dav siv nyob rau hauv cov luam Circuit Court boards ntawm 5G puag chaw nres tsheb. Nws yog tsim los ntawm ib los yog ntau txheej ntawm iav fiber ntau daim ntaub impregnated nrog epoxy resin, qhov twg cov iav fiber ntau ua hauj lwm pab raws li ib tug reinforcing khoom, muab rwb thaiv tsev thiab nce lub zog; Cov resin tshwj xeeb yog siv los ua cov khoom ntim rau daim ntawv cog lus thiab txhim kho kev ua haujlwm ntawm lub rooj tsavxwm. Txhawm rau ua kom tau raws li qhov yuav tsum tau muaj kev ntseeg siab, tsis yooj yim, kev ua haujlwm hluav taws xob, thiab kev sib dhos ua tau zoo ntawm siab - zaus thiab siab - cov khoom siv pcb ceev, ntau cov khoom siv pcb substrate tau txhim kho rau cov khoom tshwj xeeb. Raws li qhov sib txawv ntawm kev kub ceev thiab siab zaus, cov ntaub ntawv tseem ceeb pcb suav nrog tsis yog cov khoom siv epoxy nkaus xwb, tab sis kuj polytetrafluoroethylene resin, bismaleimide triazine resin, thermosetting cyanate resin, thermosetting polyphenylene ether resin, thiab polyimide resin, uas ua rau ntau tshaj 130 hom laminated. Rau lub hauv paus chaw nres tsheb pcbs, dielectric zog, teeb liab kis ceev, thiab kub tsis kam yog qhov tseem ceeb heev. Los ntawm cov cim tseem ceeb no, PTFE substrates ua tau zoo, thiab lawv cov khoom zoo heev dielectric yog qhov tsim nyog rau kev ua tiav thiab xa tawm sai ntawm cov teeb liab. Lawv yog ib qho ntawm cov khoom siv zoo tshaj plaws rau lub hauv paus chaw nres tsheb pcbs hauv 5G era.
High Tg tus nqi board: haum rau siab - zaus thiab siab - yuav tsum ceev
Tus nqi Tg, tseem hu ua iav hloov pauv kub, yog qhov ntsuas tseem ceeb rau kev ntsuas qhov ua tau zoo ntawm siab - zaus pcbs. Tawm tsam keeb kwm yav dhau los ntawm kev nce ntawm 5G, AI, thiab lwm yam kev lag luam, qhov kev thov rau siab -kev ua tau zoo pcbs tau nce zuj zus, uas tau ua rau muaj qhov nce ntxiv ntawm Tg qhov tseem ceeb. Ordinary Tg tus nqi daim hlau (FR4 daim hlau nrog Tg tus nqi qis dua 120 degree) tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm 5G kev sib txuas lus, thaum lub siab Tg tus nqi phaj (Tg tus nqi feem ntau siab dua 150 degree) tau qhia qhov zoo ntawm qhov siab - kis ceev thiab siab - zaus sib txuas lus teb. High Tg tus nqi boards tuaj yeem ua kom pom kev ruaj khov thiab txhim khu kev qha hauv kev sib txuas lus 5G thiab siab - cov ntaub ntawv xa mus ceev. Lawv xav tau tsawg dua qhov ntev voltage sawv yoj piv, txo qis teeb liab los ntawm dielectric poob, thiab qis teeb liab qeeb. Hauv cov txheej txheem pcb, Tg tus nqi siab boards muaj kev ua haujlwm zoo dua, kev cia siab, thiab kev sib raug zoo nrog lwm cov ntaub ntawv hauv kev tsim, stacking, multi- txheej txheej board layout, thiab stacked graphics.
Cov ntaub ntawv hlau: xyuas kom cov teeb liab kis tau tus mob thiab kub dissipation
Cov ntaub ntawv hlau tseem yog qhov tseem ceeb hauv 5G kev sib txuas lus boards. Piv txwv li, nyob rau hauv cov teeb liab kis tau tus mob, tooj liab yog ib tug nquag siv conductor khoom vim hais tias ntawm nws zoo conductivity, uas yuav ua kom muaj kev sib kis tau zoo ntawm cov teeb liab ntawm Circuit Court boards. Rau qhov loj ntawm cov cua sov tsim thaum lub sijhawm ua haujlwm ntawm 5G cov cuab yeej sib txuas lus, kev ntsuas kub kom zoo yuav tsum tau ua kom ntseeg tau tias cov cuab yeej ua haujlwm ruaj khov. Qee cov ntaub ntawv hlau, xws li txhuas, feem ntau yog siv los ua cov khoom cua sov dissipation xws li cov dab dej kub vim lawv cov thermal conductivity zoo thiab hnyav hnyav. Tsis tas li ntawd, nyob rau hauv ib co scenarios uas yuav tsum tau siab rau electromagnetic shielding, cov ntaub ntawv hlau nrog electromagnetic shielding zog, xws li tooj liab alloys, aluminium alloys, thiab lwm yam., yog siv. Los ntawm kev npog cov ntaub ntawv hlau rau ntawm qhov chaw lossis thaj chaw tshwj xeeb ntawm lub rooj tsav xwm hauv Circuit Court, cov khoom siv hluav taws xob sab nraud tuaj yeem cuam tshuam tau zoo, ua kom muaj kev ruaj ntseg ntawm cov teeb liab xa mus rau hauv 5G kev sib txuas lus board.
Plastics thiab cov ntaub ntawv sib xyaw: pab nrog miniaturization thiab lub teeb yuag
Nrog rau kev txhim kho 5G cov cuab yeej sib txuas lus mus rau qhov me me thiab lub teeb yuag, kev siv cov yas thiab cov khoom sib xyaw hauv 5G kev sib txuas lus thiab cov khoom sib txuas tau nce zuj zus. Siv cov kav hlau txais xov ua piv txwv, hauv 5G era, vim muaj ntau zaus bands thiab siv Massive MIMO thev naus laus zis, qhov loj ntawm cov kav hlau txais xov cov ntsiab lus tau dhau los ua me thiab cov lej tau nce ntau. Lub kav hlau txais xov yas oscillator yog tsim los ntawm cov khoom siv yas hloov kho uas muaj cov organic hlau sib xyaw, thiab cov duab 3D peb- qhov ntev yog tsim nyob rau hauv ib qho kev txhaj tshuaj molding. Cov yas saum npoo yog ces metalized los ntawm cov cuab yeej tshwj xeeb. Qhov kev daws teeb meem no tsis tsuas yog ua kom cov kav hlau txais xov ua tau raws li 5G hluav taws xob kev ua tau zoo, tab sis kuj txo cov khoom hnyav, txo cov txheej txheem txaus ntshai, thiab txuag nqi. Nyob rau tib lub sijhawm, 3D yas oscillator ua ke nrog kev txhaj tshuaj molding thiab xaiv electroplating, ob lub siab -txheej txheem txheej txheem, tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm cov kav hlau txais xov oscillators nyob rau hauv siab -frequency scenarios saum 3.5G.
Cov ntaub ntawv sib xyaw kuj qhia tau qhov tshwj xeeb zoo hauv kev sib txuas lus ntauwd thiab kav hlau txais xov npog. Piv nrog rau cov qauv steel ib txwm muaj, kev sib txuas lus yees ua los ntawm cov ntaub ntawv sib xyaw muaj qhov zoo xws li lub teeb yuag, corrosion kuj, thiab yooj yim installation. Piv txwv li, kev sib txuas lus yees ua los ntawm polyurethane cov ntaub ntawv sib xyaw yog sib dua hauv qhov hnyav thiab tuaj yeem ntsia tau sai txawm tias nyob hauv thaj chaw deb. Lawv kuj tuaj yeem tiv taus huab cua hnyav xws li daus hnyav thiab cua daj cua dub, thiab raug nqi ntau dua - zoo dua li cov pej thuam steel. UV tiv thaiv txheej ntawm qhov chaw tuaj yeem txuas ntxiv lawv lub neej kev pabcuam. Cov kav hlau txais xov npog yuav tsum muaj cov yam ntxwv zoo ntawm electromagnetic yoj nkag mus thiab muaj zog txhua yam kom tiv taus qhov hnyav. Hauv 5G qauv, siab-cov ntaub ntawv sib xyaw ua tau zoo tau dhau los ua qhov kev xaiv nrov, xws li cov iav fiber ntau siv cov yas yas, uas tuaj yeem muab rwb thaiv tsev, tiv thaiv- xeb, tiv thaiv xob laim, tiv thaiv- cuam tshuam, ua haujlwm ntev, thiab muaj txiaj ntsig zoo ntawm kev sib kis.
