Multi-Layer PCB inoreva kudhindwa redunhu bhodhi rine zvidimbu zvinopfuura zviviri zvemhangura, zvakadai se4 layer pcb, 6L, 8L, 10L, 12L, nezvimwewo. Sezvo teknolojia inovandudza, vanhu vanogona kuisa zvidimbu zvemhangura zvakawanda pabhodhi rimwe chete. Parizvino, tinogona kugadzira 20L-32L FR4 PCB.
Nechimiro ichi, mainjiniya anogona kuisa trace pamatanho akasiyana echinangwa chakasiyana, senge mitsara yesimba, yekufambisa chiratidzo, yeEMI kudzivirira, yekubatanidza zvikamu, zvichingodaro. Kuti udzivise zvidimbu zvakawandisa, Kuvigwa Via kana Bofu kuburikidza ichagadzirwa mu-multi-layer PCB. Kune bhodhi rinopfuura 8 akaturikidzana, yakakwira Tg FR4 zvinhu zvichave zvakakurumbira pane zvakajairwa Tg FR4.
More layers it is, more complex& kugadzirwa kwakaoma, uye zvakanyanya kudhura mutengo uchave. Nguva yekutungamira ye-multi-layer PCB yakasiyana neyakajairwa, ndapota taura nesu kune chaiyo yekutungamira nguva.
