So if designers want to design a circuit board, they must use a variety of different IC with fixed-functions, and they need prepare various types of IC, especially for large-scale manufacturers.
Ngakho-ke uma abaklami befuna ukuklama ibhodi lesifunda, kumele basebenzise izinhlobonhlobo ze-IC ezinemisebenzi engaguquki, futhi badinga ukulungiselela izinhlobo ezahlukahlukene ze-IC, ikakhulukazi zabakhiqizi abakhulu.
