Nhoroondo Yekuvandudza yePCB Board

Kubva pakuzvarwa kwaPCB bhodhi, yakabudirira kwemakore anopfuura 70.Mukugadzira hurongwa hwemakore anopfuura 70, PCB yakave nedzimwe shanduko dzakakosha, iyo yakakurudzira kukurumidza kukura kwePCB uye yakaita kuti ikurumidze kushandiswa kune dzakasiyana siyana.Munhoroondo yese yekuvandudza yePCB, inogona kukamurwa kuita nguva nhanhatu.

(1) Zuva rekuzvarwa kwePCB.PCB yakazvarwa kubva muna 1936 kusvika mukupera kwema1940.Muna 1903, Albert Hanson akatanga kushandisa pfungwa ye "mutsara" uye akaishandisa kune nhare yekuchinja nhare.Pfungwa yekugadzira yeiyi pfungwa ndeyekucheka simbi yakatetepa foil kuita masekete conductor, wobva waanamira pabepa reparafini, uye pakupedzisira unama pepa reparafini paari, nokudaro uchigadzira chimiro chechimiro chePCB yanhasi.Muna 1936, Dr. Paul Eisner vakanyatsogadzira teknolojia yekugadzira yePCB.Iyi nguva inowanzoonekwa senguva chaiyo yekuzvarwa kwePCB.Munguva ino yenhoroondo, maitiro ekugadzira anogamuchirwa ePCB inzira yekuputira, nzira yekupfapfaidza, vacuum deposition nzira, evaporation nzira, makemikari deposition nzira uye nzira yekuputira.Panguva iyoyo, PCB yaiwanzo shandiswa mumaredhiyo anogamuchira.

(2) Muedzo wekugadzira nguva yePCB.Iyo PCB yekuedza yekugadzira nguva yaive muma1950s.Nekuvandudzwa kwePCB, kubvira 1953, indasitiri yekugadzira michina yekukurukurirana yakatanga kutarisisa PCB uye yakatanga kushandisa PCB yakawanda.Munguva ino yenhoroondo, nzira yekugadzira yePCB ndiyo nzira yekubvisa.Iyo chaiyo nzira ndeyekushandisa mhangura yakapfava yakaonda mapepa-based phenolic resin laminate (PP zvinhu), uye ipapo kushandisa makemikari kunyungudutsa isingadikanwi yemhangura foil, kuitira kuti yakasara yemhangura foil iite dunhu.Panguva ino, makemikari emushonga wekuora unoshandiswa kuPCB ndeye ferric chloride.Chigadzirwa chinomiririra ndiyo inotakurika transistor radio inogadzirwa naSony, inova imwe-layer PCB ine PP substrate.

(3) Hunobatsira hupenyu hwePCB.PCB yakaiswa mukushandiswa muma1960s.Kubva 1960, makambani eJapan akatanga kushandisa GE base materials (copper-clad glass cloth epoxy resin laminate) yakawanda.Muna 1964, kambani yeAmerican optical circuit yakagadzira electroless copper plating solution (cc-4 solution) yemhangura inorema, nokudaro kutanga nzira itsva yekuwedzera yekugadzira.Hitachi yakaunza cc-4 tekinoroji kugadzirisa matambudziko ekudziya warping deformation uye kubviswa kwemhangura yeGe substrates padanho rekutanga.Nekuvandudzwa kwekutanga kwehunyanzvi hwezvinhu, mhando yeGe base zvinhu inoramba ichivandudza.Kubva 1965, vamwe vagadziri vakatanga kugadzira maGe substrates, Ge substrates yezvigadzirwa zvemagetsi zveindasitiri uye PP substrates ye civil electronic equipment muJapan.
