| Ukuthelekiswa koMahluko phakathi kwe-IPC2 kunye nemigangatho ye-IPC3 | ||
| Ukuthelekisa umahluko phakathi kwe-IPC2 kunye nemigangatho ye-IPC3 yeePCB zeemoto: | ||
| Inqanaba le-IPC libonisa umgangatho womgangatho wodidi ngalunye lwebhodi yesekethe eprintiweyo, kwaye abanye abavelisi be-elektroniki banamandla okuvelisa i-IPC yokuqala neyesibini imveliso. Ngexesha elifutshane, akunakubakho umahluko obonakalayo, kodwa ekuhambeni kwexesha, imiba yomgangatho wemveliso iba ngakumbi. Ukuba imveliso yakho yeyebakala loshishino kwaye ugxininisa kwixabiso lexesha elide lemveliso, nceda uqiniseke ukuba ukhetha umgangatho ophezulu. Imigangatho yomgangatho iquka IPC1, IPC2, IPC3, GJB362C-2021,AS9100 | ||
