| Uthelekiso lomahluko phakathi kwemigangatho ye-IPC2 kunye ne-IPC3 | ||
| Uthelekiso lomahluko phakathi kwemigangatho ye-IPC2 kunye ne-IPC3 yee-PCB zeemoto: | ||
| Inqanaba le-IPC libonisa umgangatho wohlobo ngalunye lwebhodi yesekethe eprintiweyo, kwaye abanye abavelisi be-elektroniki banokukwazi ukuvelisa iimveliso zenqanaba lokuqala nelesibini le-IPC kuphela. Ngexesha elifutshane, kusenokungabikho mahluko ubonakalayo, kodwa ngokuhamba kwexesha, imiba yomgangatho wemveliso iba yinto ebonakala ngakumbi. Ukuba imveliso yakho yeyenqanaba lemveliso kwaye ugxila kwixabiso lexesha elide lemveliso, nceda uqiniseke ukuba ukhetha umgangatho ophezulu. Imigangatho yomgangatho iquka i-IPC1, i-IPC2, i-IPC3, i-GJB362C-2021, i-AS9100 | ||
