Iprototype ye-PCB ivela kwinkqubo yokutshintshiselana ngefowuni isebenzisa ingcamango "yesekethe" ekuqaleni kwenkulungwane yama-20.Yenziwa ngokusika ifoyile yentsimbi ibe yiconductor yomgca kwaye incamathele phakathi kwamaqhekeza amabini ephepha leparafini.
I-PCB ngokwenyani yazalwa ngeminyaka yoo-1930.Yenziwe ngoshicilelo lwe-elektroniki.Kwathatha ibhodi yokugquma njengesiseko, isikwe kwisayizi ethile, idityaniswe kunye nepateni enye ye-conductive, kwaye ihlelwe kunye nemingxuma (efana nemingxuma yecandelo, imingxuma yokubopha, imingxuma ye-metallization, njl.) Ukubuyisela i-chassis yesixhobo sangaphambili amacandelo e-elektroniki, kwaye uqaphele uqhagamshelwano phakathi kwamacandelo e-elektroniki, Idlala indima yokuhanjiswa kwe-relay, yinkxaso yamacandelo e-elektroniki, eyaziwa ngokuba "ngumama weemveliso ze-elektroniki".
Imbali yophuhliso lwePCB eTshayina
Ngowe-1956, iChina yaqalisa ukuphuhlisa iPCB.
Ngama-1960, iphaneli enye yaveliswa kwibhetshi, iphaneli enamacala amabini yaveliswa kwibhetshi encinci, kwaye iphaneli yoluhlu oluninzi yaphuhliswa.
Ngeminyaka yoo-1970, ngenxa yokusikelwa umda kweemeko zembali ngelo xesha, uphuhliso lobuchwepheshe bePCB lwalucotha, nto leyo eyenza ukuba yonke iteknoloji yemveliso ibe semva kwinqanaba eliphezulu lamazwe angaphandle.
Ngeminyaka yoo-1980, imigca yemveliso yePCB ekwicala elinye, enamacala amabini kunye nenemigangatho emininzi yaziswa evela phesheya, eyathi yaphucula umgangatho wemveliso yePCB eTshayina.
Kwiminyaka yoo-1990, abavelisi bePCB bangaphandle abafana neHong Kong, Taiwan kunye neJapan beze eTshayina ukuza kuseka amashishini adibeneyo kunye neefektri eziphethwe ngokupheleleyo, nto leyo eyenza ukuba imveliso yePCB yaseTshayina iqhubele phambili ngobuchwephesha ngokutsiba nemida.
Ngo-2002, yaba ngumvelisi wesithathu omkhulu wePCB.
Ngo-2003, zombini ixabiso lemveliso ye-PCB kunye nexabiso lokungenisa kunye nokuthumela ngaphandle liye ladlula i-US $ 6 yebhiliyoni, yodlula i-United States okokuqala kwaye yaba ngumvelisi we-PCB wesibini ngobukhulu emhlabeni.Umlinganiselo wexabiso lemveliso yePCB unyuke ukusuka kwi-8.54% ngo-2000 ukuya kwi-15.30%, phantse kabini.
Ngo-2006, i-China ithathe indawo ye-Japan njengeyona ndawo inkulu yemveliso ye-PCB yehlabathi kunye nelona lizwe lisebenzayo kuphuhliso lobugcisa.
Kwiminyaka yakutshanje, ishishini PCB China ligcine izinga lokukhula okukhawulezayo malunga 20%, phezulu kakhulu kunezinga lokukhula kushishino PCB zehlabathi.Ukusukela ngo-2008 ukuya ku-2016, ixabiso lemveliso yePCB yaseTshayina linyuke lisuka kwi-15.037 yeebhiliyoni zeedola ukuya kwi-27.123 yeebhiliyoni zeedola, kunye nezinga lokukhula lonyaka elihlanganisiweyo le-7.65%, liphezulu kakhulu kune-1.47% yezinga lokukhula kwekhompawundi yehlabathi.Idatha yePrismark ibonisa ukuba ngo-2019, ixabiso lemveliso ye-PCB yehlabathi limalunga ne-61.34 yeebhiliyoni zeedola, apho ixabiso lemveliso yePCB yaseTshayina lizibhiliyoni ezingama-32.9 zeedola, libalelwa kwi-53.7% yentengiso yehlabathi.
