5G, Lub Kaum Ib Hlis Tom Ntej Ntawm Tuam Tshoj PCB

5G thev naus laus zis hloov pauv, xov tooj cua zaus yog qhov tseem ceeb tshaj plaws, ob qho tib si PCB tawm tsam thiab tiv thaiv. Lub nthwv dej tom ntej ntawm 5G kev tsim kho hauv 2019 yuav qhib qhov chaw tshiab rau kev lag luam sab saud. Xav txog qhov kev txhim kho zaus thiab qeeb qeeb, 5G tsis tsuas yog txawv ntawm 4G hauv kev tsim qauv tsim qauv, tab sis kuj tso cov kev xav tau tshiab rau cov khoom siv xov tooj cua wireless. Cov lim, kav hlau txais xov, kev co, PCB thiab lwm yam txuas tau hloov pauv. Kev ua lag luam tsis quav ntsej qhov zoo ntawm PCB txheeb ze rau lwm cov xov tooj cua sib txuas. Peb ntseeg hais tias PCB tau paub tab, tsim cov cuab yeej technology thiab muaj peev xwm tiv thaiv, thiab zoo ib yam li cov fiber ntau optic cables. Txawm hais tias tus nqi ntawm cov khoom siv sib txuas lus yog loj, cov khoom siv sib txuas lus cov neeg muag khoom tsis ncaj qha rau hauv kev lag luam kev sib tw qauv. Zoo sib xws, nyob rau tib lub sijhawm, txoj cai tswj hwm kev tiv thaiv ib puag ncig hauv lub tebchaws tau ua rau muaj kev sib tw kom zoo dua maj mam mloog zoo rau lub taub hau manufacturers. Cov nyiaj tau los tag nrho ntawm Shanghai thiab TV thiab Shennan tau ua pov thawj los ntawm tsib xyoos dhau los.

5G lub hauv paus chaw nres tsheb ob npaug, thiab cov kev hloov hauv wireless architecture tau tsav PCB ntim thiab cov nqi. (MIMO) 技术的采用,5G 对小型化, 集成化要求更高, 在射频单元(AAU)中, Ib feem uas thawj zaug txuas los ntawm feeder tau maj mam hloov mus rau PCB, thiab yav tom ntej nrog kev txhim kho, high-frequency bands thiab millimeter yoj bands, tus nqi ntawm PCB suav nrog cov khoom siv sib txuas lus yuav tsum tau nce los ntawm 2 feem pua ​​​​rau 5 feem pua ​​-6 feem pua. Kev kwv yees dav dav, lub ntiaj teb tag nrho kev lag luam loj ntawm 5G lub hauv paus chaw nres tsheb PCB pawg thawj coj saib yog 116.5 billion yuan, uas yog 5.5 npaug ntawm lub sijhawm 4G; Kev lag luam thoob ntiaj teb loj ntawm 5G kev tsim kho yog 26.9 billion, thiab kev lag luam hauv tsev loj yog 16.1 billion.

PCB upstream high-frequency high-speed tooj liab-cov ntaub ntawv npog yog cov tub ntxhais, thiab qhov chaw hloov pauv hloov pauv loj. Kev ua lag luam ntseeg tias kev loj hlob ntawm PCB feem ntau yog nyob ntawm "ntau". Nyob rau hauv thaum ntxov 5G, cov kev cai rau PCB tsis siab rau nruab nrab-frequency band ntawm 2.6G thiab 3.5G, tab sis peb ntseeg hais tias daim ntawv thov ntawm high-frequency thiab high-ceev boards yuav siv tau thoob plaws hauv daim ntawv thov ntawm high-frequency. thiab high-speed boards siv nyob rau hauv kev siv ntawm high-frequency thiab high-speed boards siv nyob rau hauv kev siv ntawm high-frequency thiab high-ceev daim hlau. Tag nrho nruab nrab-rau-high-frequency thiab millimeter nthwv dej theem, 5G qis latency, siab ntseeg tau, tsis tshua muaj zog noj cov yam ntxwv tso rau pem hauv ntej cov kev xav tau ntau dua rau tooj liab npog daim hlau. Tus thawj coj thoob ntiaj teb hauv ntiaj teb tshwj xeeb yog tsom rau 5G MIMO kav hlau txais xov thiab lub neej yav tom ntej siab. Ntau zaus thiab millimeter nthwv dej tau pib lub npog tooj liab.

Tus thawj coj tau nce los ntawm qhov sib txawv, lub zeem muag thoob ntiaj teb yog nyiam, Shennan Circuit Court, Shanghai Power Co., Ltd., Dongshan Precision, thiab Rogers. Kev lag luam PCB tau dhau los ua ib nthwv dej loj ntawm cov qhaub cij. Nyob rau hauv ib qho chaw sib tw ruaj khov, peb muaj lub zeem muag thoob ntiaj teb. Saib ntawm lub sijhawm luv luv, lub tuam txhab ua lag luam muaj kev nthuav dav ntawm cov peev txheej tsim tawm los ntawm hauv qab mus rau hauv qab, uas yuav tsum tau tso tawm lub peev xwm ntau lawm hauv 2019-2020. Kev loj hlob ntawm peb lub hlis twg ntawm lub xyoo no tau tam sim no tau coj tawm. Nyob rau lub sijhawm ntev, PCB tus qauv ntawm Huawei, ZTE, thiab Ericsson twb tau nyob rau hauv lub sijhawm ntev PCB tus qauv. Nws ruaj khov dua thiab tsuas yog yuav tsum tau tso tawm los ntawm qhov kev thov rau 5G high-end khoom.
