Iyo prototype yePCB inouya kubva kunhare yekutsinhana nhare ichishandisa pfungwa ye "dunhu" mukutanga kwezana ramakore rechi20.Inogadzirwa nekucheka simbi foil kuita line conductor uye kuinamira pakati pezvidimbu zviviri zvepepa reparafini.
PCB mupfungwa yechokwadi yakazvarwa muma1930s.Yakagadzirwa nemagetsi kudhinda.Zvaitora insulating board sechinhu chepasi, chakachekwa kuita imwe saizi, yakasungirirwa neinenge imwe conductive pateni, uye yakarongedzwa nemakomba (senge maburi echikamu, maburi ekusunga, maburi esimbi, nezvimwewo) kutsiva chassis yechishandiso chekare. zvikamu zvemagetsi, uye kuziva kuwirirana pakati pezvikamu zvemagetsi, Inotamba basa rekutumira relay, itsigiro yezvikamu zvemagetsi, inozivikanwa se "amai vezvigadzirwa zvemagetsi".
Nhoroondo yePCB budiriro muChina
Muna 1956, China yakatanga kugadzira PCB.
Muma1960, pani imwe chete yakagadzirwa mubatch, iyo ine mativi maviri-yakapetwa pani yakagadzirwa mudiki batch, uye iyo yakawanda-layer panel yakagadzirwa.
Mumakore ekuma1970, nekuda kwekudzikira kwemamiriro ezvinhu ekare panguva iyoyo, kusimukira kwePCB tekinoroji kwainonoka, izvo zvakaita kuti tekinoroji yese yekugadzira isare kumashure kwedanho repamusoro renyika dzekunze.
Mumakore ekuma1980, mitsara yekugadzira yepamberi imwechete, yakapetwa kaviri uye yakawanda-layer PCB yakaunzwa kubva kunze kwenyika, iyo yakavandudza danho rekugadzira tekinoroji yePCB muChina.
Mumakore ekuma1990, vagadziri vePCB vekune dzimwe nyika vakaita seHong Kong, Taiwan neJapan vauya kuChina kuzogadzira mafekitori akabatana nemafekitori, izvo zvinoita kuti kugadzirwa kwePCB yeChina uye tekinoroji ifambire mberi nekusvetuka-svetuka.
Muna 2002, yakava yechitatu yakakura PCB mugadziri.
Muna 2003, zvese zviri zviviri PCB yakabuda uye kukosha kwekunze kwenyika kwakapfuura US $ 6 bhiriyoni, ichipfuura United States kekutanga uye ikava yechipiri pakukura PCB mugadziri pasi rose.Chiyero chePCB yekubuda kukosha chakawedzera kubva pa8.54% muna 2000 kusvika 15.30%, yakapetwa kaviri.
Muna 2006, China yakatsiva Japan senzvimbo huru yepasi rose yePCB yekugadzira uye nyika inoshanda zvakanyanya mukuvandudza tekinoroji.
Mumakore achangopfuura, indasitiri yePCB yekuChina yakaramba ichikura nekukurumidza inosvika makumi maviri muzana, yakakwira zvakanyanya kudarika mwero wekukura kweindasitiri yePCB yepasi rose.Kubva 2008 kusvika 2016, kukosha kwekubuda kweindasitiri yePCB yeChina kwakawedzera kubva kuUS $15.037 bhiriyoni kuenda kuUS $27.123 bhiriyoni, ine huwandu hwekukura kwepagore hwe7.65%, iyo yakakwira zvakanyanya kupfuura 1.47% yehuwandu hwekukura kwepasi rose.Prismark data inoratidza kuti muna 2019, iyo yepasi rose PCB indasitiri yekuburitsa kukosha ingangoita madhora mazana matanhatu nemakumi matatu nemana emadhora, iyo yeChina PCB yekuburitsa kukosha inosvika bhiriyoni makumi matatu neshanu, inoverengera 53.7% yemusika wepasi rose.
