| Kugereranya itandukaniro riri hagati y'amahame ya IPC2 na IPC3 | ||
| Kugereranya itandukaniro riri hagati y’amahame ya IPC2 na IPC3 ku bikoresho bya PCB by’imodoka: | ||
| Urwego rwa IPC rugaragaza urwego rw'ubuziranenge bwa buri bwoko bw'urubaho rwacapwe, kandi bamwe mu bakora ibikoresho by'ikoranabuhanga bafite ubushobozi bwo gukora ibicuruzwa bya IPC byo ku rwego rwa mbere n'urwa kabiri gusa. Mu gihe gito, hashobora kutagira itandukaniro rigaragara, ariko uko igihe kigenda gihita, ibibazo by'ubuziranenge bw'ibicuruzwa birarushaho kugaragara. Niba ibicuruzwa byawe ari iby'urwego rw'inganda kandi ukibanda ku gaciro k'igihe kirekire k'ibicuruzwa, nyamuneka menya neza ko wahisemo ibipimo by'ubuziranenge byo ku rwego rwo hejuru. Ibipimo by'ubuziranenge bigizwe na IPC1, IPC2, IPC3, GJB362C-2021, AS9100 | ||
