PCB Isingeniso
Ibhodi lesifunda eliphrintiwe lakhiwe ipuleti elingaphansi elivikelayo, intambo yokuxhuma kanye nephedi yokuhlanganisa nokushisela izingxenye ze-elekthronikhi, futhi inemisebenzi emibili yesekethe yokuqhuba kanye nepuleti elingaphansi elivikelayo.Ingakwazi ukufaka izintambo eziyinkimbinkimbi futhi ibone ukuxhumana kukagesi phakathi kwezingxenye ezihlukahlukene ezisesekethe.Akwenzi kube lula nje ukuhlanganisa nokushisela imikhiqizo ye-elekthronikhi, kunciphisa umthwalo wezintambo ngendlela evamile, futhi kunciphisa kakhulu umfutho wokusebenza kwabasebenzi;iphinde yehlise iVolume yomshini uwonke, inciphise izindleko zomkhiqizo, futhi ithuthukise ikhwalithi nokuthembeka kwemishini kagesi.Ibhodi lesifunda eliphrintiwe linokungaguquguquki okuhle komkhiqizo, futhi lingakwazi ukusebenzisa ukwakheka okujwayelekile, okuhambisana nokufezeka kokusebenza kwemishini kanye ne-automation enqubweni yokukhiqiza.Ngesikhathi esifanayo, lonke ibhodi lesifunda eliphrintiwe elihlanganisiwe futhi lalungiswa iphutha lingasetshenziswa njengengxenye ezimele eyisipele ukuze kube lula ukushintshaniswa nokugcinwa komkhiqizo wonke.Njengamanje, amabhodi esekethe aphrintiwe asetshenziswe kabanzi kakhulu ekwenzeni imikhiqizo ye-elekthronikhi.
Amabhodi esekethe okuqala aphrintiwe asebenzisa amabhodi aphrintiwe enziwe nge-copper-clad.Selokhu kwavela ama-semiconductor transistors ngeminyaka yawo-1950, isidingo samabhodi aphrintiwe sikhuphuke kakhulu.Ikakhulukazi, ukuthuthukiswa okusheshayo kanye nokusetshenziswa okubanzi kwama-circuits ahlanganisiwe kwenze umthamo wemishini kagesi ube mncane futhi ube mncane, futhi ukuminyana nobunzima be-wiring yesifunda kuye kwanda kakhulu, okudinga ukubuyekezwa okuqhubekayo kwamabhodi aphrintiwe.Njengamanje, izinhlobonhlobo zamabhodi aphrintiwe ziye zathuthukiswa kusukela emabhodini ohlangothini olulodwa kuya kumabhodi anezinhlangothi ezimbili, amabhodi amaningi kanye namabhodi aguquguqukayo;ukwakheka kanye nekhwalithi nakho kuthuthuke kwaba ukuminyana okuphezulu kakhulu, ukwenza i-miniaturization kanye nokuthembeka okuphezulu;izindlela ezintsha zokuklama, izimpahla zokuklama kanye nezinto zokwakha iBhodi kanye nezindlela zokwenza amabhodi ziyaqhubeka nokuvela.Eminyakeni yakamuva, isoftware yebhodi lesifunda ephrintiwe ye-computer-aid (CAD) iye yaduma futhi yathuthukiswa embonini.Phakathi kwabakhiqizi abakhethekile bamabhodi aphrintiwe, ukukhiqizwa kwemishini nokuzenzakalelayo kuthathele indawo yonke imisebenzi eyenziwa ngesandla.
Umsuka
Umqambi we-PCB ngu-Austrian Paul Eisler (Paul Eisler), ngo-1936, waqala ukusebenzisa ibhodi lesifunda eliphrintiwe emsakazweni.Ngo-1943, amaMelika ayesebenzisa kakhulu lobu buchwepheshe kumarediyo ezempi.Ngo-1948, i-United States yagunyaza ngokusemthethweni lokhu kusungulwa ukuze kusetshenziselwe ukuhweba.Kusukela maphakathi nawo-1950, amabhodi esekethe aphrintiwe aseqale ukusetshenziswa kakhulu.Amabhodi esekethe aphrintiwe avela cishe kuzo zonke izisetshenziswa zikagesi.Uma kunezingxenye ze-electronic kudivayisi ethile, zonke zifakwe kuma-PCB osayizi abahlukene.Umsebenzi oyinhloko we-PCB ukuxhuma izingxenye ezihlukahlukene ze-elekthronikhi kwisekethe enqunywe kusengaphambili futhi idlale indima yokudlulisela ukudluliselwa.Kuwukuxhumana okubalulekile kwe-elekthronikhi kwemikhiqizo kagesi futhi kwaziwa ngokuthi "umama wemikhiqizo kagesi".
