Liyini ibhodi lesifunda elinezingqimba eziningi, futhi yiziphi izinzuzo zebhodi lesifunda le-PCB elinezingqimba eziningi?Njengoba igama liphakamisa, ibhodi lesifunda elinezingqimba eziningi lisho ukuthi ibhodi lesifunda elinezingqimba ezingaphezu kwezimbili lingabizwa ngokuthi i-multi-layer.Ngihlaziye ukuthi ibhodi lesifunda elinamaceleni amabili liyini ngaphambili, futhi ibhodi lesifunda elinezingqimba eziningi lingaphezu kwezingqimba ezimbili, njengezingqimba ezine, izingqimba eziyisithupha, i-Eighth floor nokunye.Vele, eminye imiklamo inezingqimba ezintathu noma iziyingi ezinhlanu, ezibizwa nangokuthi amabhodi wesekethe we-PCB anezingqimba eziningi.Inkulu kunomdwebo we-wiring we-conductive webhodi elinezingqimba ezimbili, izendlalelo zihlukaniswa ngama-substrates avikelayo.Ngemuva kokuthi ungqimba ngalunye lwesekhethi luphrintiwe, ungqimba ngalunye lwesekhethi lumbozwa ngokucindezela.Ngemva kwalokho, izimbobo zokumba zisetshenziselwa ukuqaphela ukuqhutshwa phakathi kwemigqa yongqimba ngalunye.
Inzuzo yamabhodi wesekethe we-PCB enezingqimba eziningi ukuthi imigqa ingasatshalaliswa ngezigaba eziningi, ukuze kuklanywe imikhiqizo enembe kakhudlwana.Noma imikhiqizo emincane ingatholwa ngamabhodi anezingqimba eziningi.Okufana nalokhu: amabhodi esekethe omakhalekhukhwini, ama-micro projektha, iziqophamazwi neminye imikhiqizo emikhulu kakhulu.Ngaphezu kwalokho, izendlalelo eziningi zingakhuphula ukuguquguquka kokuklama, ukulawula okungcono kwe-impedance ehlukile kanye ne-impedance enokuphela okukodwa, kanye nokuphuma okungcono kwamanye amaza esignali.
Amabhodi wesifunda se-Multilayer angumkhiqizo ongenakugwemeka wokuthuthukiswa kobuchwepheshe be-elekthronikhi ekuqondeni kwejubane eliphezulu, imisebenzi eminingi, umthamo omkhulu kanye nevolumu encane.Ngokuthuthuka okuqhubekayo kobuchwepheshe be-elekthronikhi, ikakhulukazi ukusetshenziswa okubanzi nokujulile kwamasekethe ahlanganisiwe asezingeni elikhulu namakhulu, amasekhethi aphrintiwe ngezigaba eziningi athuthuka ngokushesha aqonde ekumineni okuphezulu, ukunemba okuphezulu, kanye nezinombolo ezisezingeni eliphakeme. ., Imbobo eyimpumputhe engcwatshwe imbobo yobukhulu bepuleti elikhulu lokuvula isilinganiso kanye nobunye ubuchwepheshe ukuze kuhlangatshezwane nezidingo zemakethe.
Ngenxa yesidingo samasekhethi anesivinini esikhulu kumakhompyutha kanye nezimboni ze-aerospace.Kudingeka ukuthi kuqhutshekwe nokwandisa ukuminyana kokupakisha, okuhambisana nokwehliswa kobukhulu bezingxenye ezihlukanisiwe kanye nokuthuthukiswa okusheshayo kwama-microelectronics, umshini we-elekthronikhi uyathuthuka ngendlela yokunciphisa usayizi nekhwalithi;ngenxa yokunqunyelwa kwendawo etholakalayo, akunakwenzeka kumabhodi aphrintiwe ohlangothini olulodwa nahlangothini oluphindwe kabili Ukwanda okwengeziwe kokuhlanganiswa komhlangano kufinyelelwa.Ngakho-ke, kuyadingeka ukucabangela ukusebenzisa ama-circuits aphrintiwe kakhulu kunezingqimba eziphindwe kabili.Lokhu kudala izimo zokuvela kwamabhodi wesekethe we-multilayer.
