Isakhiwo se-PCB siyibhodi lesifunda eliphrintiwe.Ibhodi lesifunda eliphrintiwe libizwa nangokuthi ibhodi lesifunda eliphrintiwe, eliyisithwali esivumela izingxenye ezihlukahlukene ze-elekthronikhi ukuthi zixhunywe njalo.

Isakhiwo se-PCB sihunyushwa ngesakhiwo sebhodi lesifunda esiphrintiwe ngesi-Chinese.Ibhodi lesifunda ku-craft yendabuko iyindlela yokusebenzisa ukuphrinta ukuze ikhiphe isifunda, ngakho-ke ibizwa ngokuthi ibhodi lesifunda eliphrintiwe noma eliphrintiwe.Ukusebenzisa amabhodi aphrintiwe, abantu abakwazi ukugwema kuphela amaphutha ezintambo ohlelweni lokufakwa (ngaphambi kokuvela kwe-PCB, izingxenye ze-elekthronikhi zonke zazixhunywe ngezintambo, ezingezona nje ezingcolile, kodwa futhi zinezingozi zokuphepha ezingase zibe khona).Umuntu wokuqala ukusebenzisa i-PCB kwakungu-Austrian okuthiwa uPaul.I-Eisler, yaqala ukusetshenziswa emsakazweni ngo-1936. Ukusetshenziswa okusabalele kwavela ngeminyaka yawo-1950.

Izici zesakhiwo se-PCB

Njengamanje, imboni yezogesi ithuthuke ngokushesha, futhi umsebenzi nokuphila kwabantu akuhlukaniseki emikhiqizweni ehlukahlukene ye-elekthronikhi.Njengesiphathi esibalulekile nesibalulekile semikhiqizo kagesi, i-PCB nayo idlale indima ebaluleke kakhulu.Imishini ye-elekthronikhi iveza umkhuba wokusebenza okuphezulu, isivinini, ukukhanya nokuzaca.Njengemboni yemikhakha eminingi, i-PCB isibe obunye bobuchwepheshe obubaluleke kakhulu bemishini kagesi.Imboni ye-PCB ithatha isikhundla esibalulekile kubuchwepheshe bokuxhumana ngogesi.
