A ƙarshe, bari ’ s ga menene babban yadudduka PCB.

Yayin da adadin yadudduka a allunan da'irar bugu na multilayer ke ƙaruwa, bayan na huɗu da na shida, ana ƙara ƙarin yadudduka na jan ƙarfe da dielectric abu yadudduka a cikin tari.

Misali, PCB mai Layer takwas ya ƙunshi jirage huɗu da siginar siginar tagulla guda huɗu—takwas gabaɗaya—haɗe tare da layuka bakwai na kayan lantarki. An rufe tari mai Layer takwas a sama da ƙasa tare da yaduddukan abin rufe fuska na dielectric solder. Mahimmanci, tarawar PCB mai Layer takwas yayi kama da mai Layer shida amma tare da ƙarin ginshiƙai na jan karfe da prepreg.

Yanayin yana ci gaba da PCB mai Layer 10, wanda ke ƙara ƙarin yadudduka na tagulla, jimlar siginar sigina shida da yaduddukan tagulla na jirgin sama guda huɗu—10 a duka. A cikin tari na PCB mai Layer 10, jan karfe yana haɗe da ginshiƙai tara na kayan dielectric — ginshiƙai biyar na prepreg da muryoyi huɗu. Tari-up PCB mai Layer goma an rufe shi da saman abin rufe fuska na dielectric solder, kamar duk sauran tari.

Lokacin da yazo ga tarawar PCB mai Layer 12, hukumar tana da jirage huɗu da sigina guda takwas, an haɗa su da sigina shida da ginshiƙai biyar na kayan kwalliyar dielectric. Tarin PCB mai Layer 12 an rufe shi da yaduddukan abin rufe fuska na dielectric. Gabaɗaya, zane-zane na PCB masu yawa suna nuna yadudduka da kayan haɗin gwiwa tare da launuka masu zuwa - launin ruwan kasa yana wakiltar sigina / jan ƙarfe na jirgin sama, launin toka yana wakiltar kayan prepreg/core dielectric, kuma kore yana wakiltar saman abin rufe fuska na sama / ƙasa.
