| Ukuqhathaniswa komehluko phakathi kwezindinganiso ze-IPC2 ne-IPC3 | ||
| Ukuqhathanisa umehluko phakathi kwezindinganiso ze-IPC2 ne-IPC3 zama-PCB ezimoto: | ||
| Izinga le-IPC libonisa izinga lekhwalithi lohlobo ngalunye lwebhodi lesifunda eliphrintiwe, futhi abanye abakhiqizi be-elekthronikhi banekhono lokukhiqiza imikhiqizo yezinga lokuqala nelesibili le-IPC kuphela. Esikhathini esifushane, kungase kungabi nomehluko obonakalayo, kodwa ngokuhamba kwesikhathi, izinkinga zekhwalithi yomkhiqizo ziba zivelele kakhulu. Uma umkhiqizo wakho ungowezinga lezimboni futhi ugxila enanini lesikhathi eside lomkhiqizo, sicela uqiniseke ukuthi ukhetha izinga eliphakeme. Izindinganiso zekhwalithi zihlanganisa i-IPC1, i-IPC2, i-IPC3, i-GJB362C-2021, i-AS9100 | ||
