Ibhodi yesekethe eprintiweyo (Ibhodi yesekethe eprintiweyo, ekubhekiselwa kuyo ngokuba yiPCB) yi-substrate yokudibanisa iinxalenye ze-elektroniki, kwaye ibhodi eprintiweyo eyenza udibaniso lwe-point-to-point kunye namacandelo aprintiweyo kwi-substrate ngokubanzi ngokuyila kwangaphambili.Umsebenzi ophambili we-PCB kukwenza iintlobo ngeentlobo zezixhobo zombane zenza uqhagamshelwano lwesekethe esele lumiselwe, ludlale indima yothumelo lodluliselo, lunxibelelwano olungundoqo lwe-elektroniki lweemveliso zombane.
Umgangatho wokwenziwa kweebhodi zeesekethe eziprintiweyo azichaphazeli ngokuthe ngqo ukuthembeka kweemveliso ze-elektroniki, kodwa kwakhona kuchaphazela ukukhuphisana ngokubanzi kweemveliso zenkqubo, ngoko i-PCB yaziwa ngokuba "umama weemveliso ze-elektroniki".
Okwangoku, iintlobo ngeentlobo zeemveliso zombane ezifana iikhompyutha zobuqu, iifowuni eziphathwayo, iikhamera yedijithali, izixhobo zombane, isithuthi satellite navigation izixhobo, iinxalenye imoto drive kunye nezinye iisekethe, zonke zisebenzisa iimveliso PCB, leyo inokubonwa yonke indawo kubomi bethu bemihla ngemihla.
Ngomkhwa woyilo wemisebenzi eyahlukeneyo, i-miniaturization kunye nobunzima obukhaphukhaphu beemveliso ze-elektroniki, izixhobo ezincinci ngakumbi zongezwa kwi-PCB, kusetyenziswa iileya ezingaphezulu, kunye nokuxinana kokusetyenziswa kwesixhobo nako kuyanda, okwenza usetyenziso lwePCB lube nzima.
I-PCB engenanto yeBhodi ngokusebenzisa iinxalenye ze-SMT (i-surface mount technology), okanye nge-DIP (i-double in-line package) iplagi-in-plug-in kuyo yonke inkqubo, ekubhekiselwa kuyo njenge-PCBA (iNdibano yeBhodi yeSekethe eShicileleyo).
