Umlando Wokuthuthukiswa Kwe-PCB E-China

I-prototype ye-PCB ivela ohlelweni lokushintshisana ngocingo kusetshenziswa umqondo "wesifunda" ekuqaleni kwekhulu lama-20.Yenziwa ngokusika i-foil yensimbi ibe yi-conductor yomugqa bese iyinamathisela phakathi kwezingcezu ezimbili zephepha likapharafini.

I-PCB ngomqondo weqiniso yazalwa ngawo-1930.Yenziwe ngokuphrinta nge-elekthronikhi.Kuthathe ibhodi lokuvikela njengesisekelo, lisikwe usayizi othile, linamathiselwe okungenani iphethini eyodwa yokushayela, futhi lihlelwe ngezimbobo (njengezimbobo zengxenye, izimbobo zokubopha, izimbobo ze-metallization, njll.) ukuze kungene indawo ye-chassis yedivayisi yangaphambilini. Izingxenye ze-elekthronikhi, futhi ibone ukuxhumana phakathi kwezingxenye ze-elekthronikhi, Idlala indima yokudluliselwa kokudluliselwa, ukusekelwa kwezingxenye ze-elekthronikhi, ezaziwa ngokuthi "umama wemikhiqizo ye-elekthronikhi".

Umlando wokuthuthukiswa kwe-PCB e-China

Ngo-1956, i-China yaqala ukuthuthukisa i-PCB.

Ngawo-1960, iphaneli eyodwa yakhiqizwa ngeqoqo, iphaneli enamacala amabili yakhiqizwa ngamaqoqo amancane, futhi iphaneli enezingqimba eziningi yathuthukiswa.

Ngawo-1970, ngenxa yokunqunywa kwezimo zomlando ngaleso sikhathi, ukuthuthukiswa kobuchwepheshe be-PCB kwakuhamba kancane, okwenza bonke ubuchwepheshe bokukhiqiza busale ngemuva kwezinga eliphezulu lamazwe angaphandle.

Ngawo-1980, imigqa yokukhiqiza ethuthukisiwe ye-PCB enohlangothi olulodwa, enezinhlangothi ezimbili kanye neyezingqimba eziningi yethulwa phesheya, okwathuthukisa izinga lobuchwepheshe bokukhiqiza be-PCB eChina.

Ngeminyaka yawo-1990, abakhiqizi be-PCB bakwamanye amazwe abafana ne-Hong Kong, Taiwan kanye ne-Japan beze e-China ukuzosungula amafekthri ahlanganyelwe kanye nezimboni eziphethwe ngokuphelele, okwenza ukukhiqizwa nobuchwepheshe be-PCB yase-China kuthuthuke ngokushesha nangemingcele.

Ngo-2002, yaba ngumkhiqizi wesithathu omkhulu we-PCB.

Ngo-2003, kokubili inani le-PCB lokukhipha kanye nenani lokungenisa kanye nokuthekelisa ladlula ama-US $6 wezigidigidi, ladlula i-United States okokuqala ngqa futhi yaba umkhiqizi we-PCB wesibili ngobukhulu emhlabeni.Ingxenye yenani lokuphuma kwe-PCB lenyuke lisuka ku-8.54% ngo-2000 laya ku-15.30%, licishe liphindeke kabili.

Ngo-2006, i-China ithathe indawo yase-Japan njengesizinda sokukhiqiza se-PCB esikhulu kunazo zonke emhlabeni kanye nezwe elisebenza kakhulu ekuthuthukisweni kobuchwepheshe.

Eminyakeni yamuva, imboni ye-PCB yaseShayina igcine izinga lokukhula ngokushesha elingama-20%, eliphakeme kakhulu kunezinga lokukhula lomkhakha we-PCB womhlaba wonke.Kusukela ngo-2008 kuya ku-2016, inani lomkhiqizo wemboni ye-PCB yaseChina lenyuke lisuka ku-US $15.037 billion laya e-US $27.123 billion, ngezinga lokukhula elihlanganisiwe lonyaka lika-7.65%, elingaphezulu kakhulu kuka-1.47% wezinga lokukhula kwenhlanganisela yomhlaba wonke.Idatha ye-Prismark ikhombisa ukuthi ngonyaka ka-2019, inani lokuphuma kwemboni ye-PCB yomhlaba wonke licishe libe ngama-dollar ayizigidi eziyizinkulungwane ezingama-61.34, lapho inani lokuphuma kwe-PCB yaseChina lingama- $ 32.9 billion, okubalelwa ku-53.7% wemakethe yomhlaba.
