5G cov cuab yeej sib txuas lus tau ntsib cov kev xav tau siab dua ntawm kev ua tau zoo, qhov loj me thiab kev ua haujlwm sib koom ua ke, thiab cov txheej txheem ntau yam hloov pauv tau yooj yim, nrog rau lawv cov kev hloov pauv tau zoo, nyias thiab lub teeb cov yam ntxwv thiab kev tsim qauv siab, tau dhau los ua cov khoom txhawb nqa tseem ceeb rau 5G cov khoom siv sib txuas lus kom ua tiav cov khoom siv me me thiab kev ua haujlwm siab, qhia ntau yam kev siv tseem ceeb hauv kev sib txuas lus ntawm 5G khoom.
Ib, Daim ntawv thov ntawm multilayer saj zawg zog Circuit Court board nyob rau hauv 5G kev sib txuas lus khoom
（一） Cov khoom siv hauv chaw nres tsheb
Hauv 5G hauv paus chaw nres tsheb, ntau txheej txheej hloov pauv tau siv dav hauv RF modules. Vim tias 5G lub hauv paus chaw nres tsheb yuav tsum tau txhawb nqa ntau zaus bandwidth thiab loj bandwidth, tus tsim ntawm RF modules tau ua ntau nyuaj, thiab cov teeb liab kis tau tus mob thiab spatial layout ntawm lub Circuit Court board yog heev xav tau. Multi-layer flexible circuit board tuaj yeem paub qhov sib kis tau zoo ntawm RF teeb liab los ntawm kev tsim cov qauv tsim hluav taws xob, thiab nws cov yam ntxwv kho tau tuaj yeem hloov mus rau cov qauv kev sib txuas ntawm lub hauv paus chaw nres tsheb, txuag chaw thiab txhim kho kev sib koom ua ke ntawm cov khoom siv. Piv txwv li, nyob rau hauv lub kav hlau txais xov array kev twb kev txuas ib feem ntawm lub hauv paus chaw nres tsheb, lub multi-layer hloov tau lub rooj tsavxwm tau raug txuas ntau lub kav hlau txais xov mus rau RF pem hauv ntej-kawg module los xyuas kom meej qhov ruaj ntseg kis tau tus mob ntawm cov teeb liab thiab kev ua haujlwm ntawm tus kav hlau txais xov.
Nyob rau hauv lub hwj chim module ntawm lub hauv paus chaw nres tsheb, lub multi-layer saj zawg zog Circuit Court board kuj plays lub luag hauj lwm tseem ceeb. Nws tuaj yeem paub txog kev faib tawm thiab kev tswj xyuas cov khoom siv hluav taws xob zoo, thiab raug thauj lub zog ntawm qhov sib txawv voltage mus rau ntau yam khoom siv hluav taws xob los ntawm kev tsim kab tsim nyog los xyuas kom muaj kev ruaj ntseg ntawm cov khoom siv hauv chaw nres tsheb. Tsis tas li ntawd, cov yam ntxwv nyias thiab lub teeb ntawm ntau txheej hloov tau yooj yim hauv Circuit Court pab txo qhov hnyav tag nrho ntawm cov khoom siv hauv paus chaw nres tsheb thiab pab txhawb kev txhim kho thiab kho.
（二）Terminal khoom siv
Hauv 5G xov tooj ntawm tes thiab lwm yam khoom siv davhlau ya nyob twg, ntau txheej txheej hloov pauv tau siv dav dua. Ua ntej ntawm tag nrho cov, nyob rau hauv kev twb kev txuas ntawm lub motherboard thiab cov zaub screen, multi-layer hloov tau lub Circuit Court board plays lub luag hauj lwm tseem ceeb choj. Nws tuaj yeem tsis tsuas yog paub txog cov teeb liab kis ntawm lub motherboard thiab lub vijtsam zaub, tab sis kuj hloov mus rau qhov kev xav tau deformation ntawm lub xov tooj ntawm tes hauv cov txheej txheem folding, khoov thiab lwm yam haujlwm. Piv txwv li, folding ib feem ntawm lub xov tooj ntawm tes folding cia siab rau ntau txheej txheej ntawm lub rooj tsav xwm hloov tau yooj yim kom ua tiav qhov kev sib txuas txhim khu kev qha ntawm cov zaub thiab cov motherboard, kom ntseeg tau tias cov zaub tuaj yeem tso saib cov duab thiab tau txais cov cim taw qhia hauv lub xeev folded thiab unfolded.
Qhov thib ob, nyob rau hauv lub koob yees duab module, ib tug multi-layered flexible Circuit Court board yog siv los txuas lub koob yees duab sensor rau lub motherboard. Nrog rau kev txhim kho txuas ntxiv ntawm 5G lub xov tooj ntawm tes lub koob yees duab pixels thiab kev ua haujlwm nplua nuj, cov kev xav tau rau cov ntaub ntawv xa mus ceev thiab kev ruaj ntseg tau nce siab dua. Multi-layer flexible circuit board tuaj yeem muab cov ntaub ntawv ceev ceev thiab ruaj khov, thiab xyuas kom meej tias cov duab siab thiab cov yeeb yaj kiab uas tau ntes los ntawm lub koob yees duab tuaj yeem raug xa mus raws sijhawm thiab raug xa mus rau motherboard rau kev ua haujlwm.
Tsis tas li ntawd, nyob rau hauv cov nqe lus ntawm cov roj teeb kev twb kev txuas thiab tus ntiv tes paub module kev twb kev txuas ntawm 5G xov tooj ntawm tes, multi-layered flexible Circuit Court boards xyuas kom meej ib txwm ua hauj lwm ntawm ntau yam functional modules nrog lawv zoo saj zawg zog thiab hluav taws xob kev ua tau zoo, muab kev txhawb zog rau nyias thiab multi-functional tsim ntawm 5G xov tooj ntawm tes.
二、Technical tseev kom muaj ntawm multilayer saj zawg zog Circuit Court board nyob rau hauv 5G khoom sib txuas lus
（一）Signal kis tau tus mob
Kev kub ceev thiab qis qeeb tus yam ntxwv ntawm 5G kev sib txuas lus tau muab tso rau hauv siab heev uas yuav tsum tau rau cov teeb liab kis tau tus mob ntawm multilayer saj zawg zog Circuit Court boards. Lub Rooj Tswjhwm Saib Circuit Court yuav tsum muaj cov teeb liab kis tau tus mob tsawg heev kom ntseeg tau tias muaj kev ncaj ncees thiab raug ntawm 5G cov teeb liab thaum sib kis. Qhov no yuav tsum muaj nyob rau hauv cov khoom xaiv, kev siv cov dielectric tsis tu ncua, tsis tshua muaj substrate cov ntaub ntawv, xws li polyimide (PI), thiab kev tswj nruj ntawm qhov roughness ntawm cov khoom, txo qhov tawg thiab kev xav hauv cov txheej txheem xaim hluav taws xob. Nyob rau tib lub sijhawm, hauv kab tsim, los ntawm kev ua kom zoo dua qhov dav, qhov sib nrug thiab impedance txuam ntawm txoj kab, qhov sib txawv ntawm cov teeb liab kis tau tus mob thiab lwm yam thev naus laus zis tau txais los txhim kho kev sib kis ceev thiab tiv thaiv kev cuam tshuam ntawm lub teeb liab, thiab ua tau raws li cov kev cai nruj ntawm 5G kev sib txuas lus rau cov teeb liab kis tau tus mob.
（二） Reliability thiab stability
5G cov cuab yeej sib txuas lus feem ntau yuav tsum tau ua haujlwm ruaj khov rau lub sijhawm ntev hauv ntau qhov chaw ib puag ncig, yog li cov txheej txheem ntau yam hloov pauv hauv Circuit Court boards yuav tsum muaj kev ntseeg siab thiab ruaj khov. Raws li cov khoom siv kho tshuab, nws yuav tsum muaj peev xwm tiv taus ntau yam dabtsi yog khoov, sib ntswg thiab lwm yam deformation yam tsis muaj kab tawg, solder sib koom ua ke poob thiab lwm yam teeb meem. Qhov no yuav tsum tau siv cov khoom siv tau yooj yim tshaj plaws hauv kev tsim cov txheej txheem, xws li laser drilling, electroplating, thiab lwm yam, kom ntseeg tau tias cov kab muaj zog thiab kev ntseeg tau ntawm kev sib txuas. Hais txog kev ua haujlwm ntawm hluav taws xob, nws yog ib qho tsim nyog yuav tsum muaj qhov kub thiab txias thiab noo noo tsis kam, kom ruaj khov hluav taws xob ua haujlwm nyob rau hauv ib puag ncig hnyav xws li kub thiab av noo, thiab kom tsis txhob muaj teeb meem xws li cov teeb liab txawv txav lossis luv luv los ntawm ib puag ncig yam.
(三) Nyias thiab me me
Txhawm rau ua kom tau raws li qhov xav tau ntawm cov qauv tsim ntawm miniaturization thiab thinness ntawm 5G cov cuab yeej sib txuas lus, ntau txheej txheej hloov pauv hloov pauv yuav tsum tau txo qis lawv cov tuab thiab loj. Nyob rau hauv cov nqe lus ntawm thickness, lub ultra-thin tsim ntawm lub rooj tsavxwm Circuit Court yog pom los ntawm kev siv ultra-thin substrate cov ntaub ntawv thiab nplua kab ua technology. Piv txwv li, lub thickness ntawm lub substrate yog tswj hauv qab no 0.05mm, thiab qhov dav thiab qhov sib nrug ntawm txoj kab raug txo los txhim kho cov xov hlau ceev ntawm lub rooj tsav xwm Circuit Court. Raws li qhov loj me, los ntawm kev txhim kho kab teeb tsa thiab siv cov txheej txheem ntim qib siab, xws li nti-theem ntim (CSP) thiab cov txheej txheem ntim khoom (SiP), ntau cov khoom siv hluav taws xob tau muab tso rau hauv qhov chaw me me kom ua tiav cov txheej txheem ntawm ntau txheej hloov tau yooj yim Circuit Court boards, muab cov xwm txheej rau nyias thiab lub teeb tsim ntawm 5G cov khoom siv sib txuas lus.
Multilayer flexible circuit boards muaj ntau yam kev siv tseem ceeb hauv 5G cov khoom siv sib txuas lus, los ntawm cov khoom siv hauv chaw nres tsheb mus rau cov khoom siv davhlau ya nyob twg, tsis tuaj yeem sib cais los ntawm nws cov kev txhawb nqa. Nyob rau tib lub sijhawm, txhawm rau ua kom tau raws li qhov kev xav tau ua tau zoo ntawm 5G cov cuab yeej sib txuas lus, ntau txheej txheej hloov pauv hloov pauv tau ntsib cov kev xav tau nruj ntawm cov teeb liab kev ua tau zoo, kev ntseeg tau thiab ruaj khov, lightness thiab miniaturization.
