Lub sijhawm ntawm 5G tab tom los, thiab kev lag luam PCB yuav yog tus yeej loj tshaj plaws. Nyob rau hauv lub era ntawm 5G, nrog rau kev nce ntawm 5G zaus band, wireless signals yuav txuas mus rau ntau zaus band, lub hauv paus chaw nres tsheb ceev thiab mobile cov ntaub ntawv xam tus nqi yuav nce ntau, tus nqi ntxiv ntawm kav hlau txais xov thiab lub hauv paus chaw nres tsheb yuav hloov mus rau PCB, thiab lub kev thov ntawm high-frequency high-ceev cov cuab yeej xav tias yuav nce ntxiv rau yav tom ntej. Nyob rau theem ntawm 5G, cov ntaub ntawv xa mus tau nce ntau, thiab kev hloov pauv ntawm huab cov ntaub ntawv chaw network architecture muaj ntau dua qhov yuav tsum tau ua ntawm cov ntaub ntawv muaj peev xwm ntawm cov chaw nres tsheb. Yog li ntawd, raws li lub hauv paus ntawm 5G thev naus laus zis, kev siv cov kev xav tau ntawm high-frequency high-speed PCB yuav nce exponentially.Thaum Lub Rau Hli 6, Ministry of Industry thiab Information Technology tau tshaj tawm 5G daim ntawv tso cai rau Tuam Tshoj Telecom, China Mobile, China Unicom thiab Tuam Tshoj Xov Tooj Cua thiab TV, ua rau Tuam Tshoj yog ib qho ntawm ob peb lub teb chaws hauv ntiaj teb uas 5G muaj kev lag luam. Tam sim no, thoob ntiaj teb 5G nkag mus rau lub sijhawm tseem ceeb ntawm kev xa mus rau kev lag luam, raws li Ministry of Industry thiab Information Technology. Tuam Tshoj Unicom kwv yees tias qhov ceev ntawm 5G chaw nres tsheb yuav tsawg kawg yog 1.5 npaug ntawm 4G. Tag nrho cov naj npawb ntawm 4G hauv paus chaw nres tsheb hauv Suav teb xav tias yuav ncav cuag 4 lab ua ntej 5G muaj kev lag luam los ntawm 2020.Anxin kev ruaj ntseg ntseeg hais tias cov peev txheej nyob rau hauv pem hauv ntej kawg ntawm 5G lub hauv paus chaw nres tsheb yuav tshwm sim thawj zaug, thiab PCB, raws li cov khoom siv sib txuas lus ncaj nraim ntawm 5G wireless, muaj lub sijhawm zoo thiab qhov yuav tshwm sim ntau tshaj plaws.Fastline yuav siv tag nrho lub tuam txhab kev tshawb fawb, txuas ntxiv txhawb kev tsim kho thev naus laus zis thiab kev txhim kho txheej txheem, nthuav kev koom tes nrog lwm lub teb chaws; vigorously tsim ib qho kev pabcuam kev lag luam, thiab xyuas kom muaj kev loj hlob tsis tu ncua thiab ruaj khov ntawm peb cov kev ua tau zoo.
