Umehluko phakathiPCBibhodi lesifunda eliphrintiwe kanye nesekethe edidiyelwe:
1. Amasekhethi ahlanganisiwe ngokuvamile abhekisela ekuhlanganisweni kwama-chips, njenge-chip yebhuloho elisenyakatho ebhodini lomama, futhi ngaphakathi kwe-CPU, wonke abizwa ngokuthi amasekhethi ahlanganisiwe, futhi igama langempela libizwa nangokuthi amabhlogo ahlanganisiwe.Isifunda esiphrintiwe sibhekisela kumabhodi wesifunda esivame ukuwabona, kanye nama-chips wokuphrinta kanye ne-soldering ebhodini lesifunda.
2. Isekhethi edidiyelwe (IC) ishiselwe ebhodini le-PCB;ibhodi le-PCB lingumthwali wesekethe edidiyelwe (IC).Ibhodi le-PCB liyibhodi lesifunda eliphrintiwe (Ibhodi lesifunda eliphrintiwe, i-PCB).Amabhodi esekethe aphrintiwe atholakala cishe kuzo zonke izisetshenziswa zikagesi.Uma kunezingxenye ze-electronic kudivayisi ethile, amabhodi esekethe aphrintiwe afakwa kuma-PCB anosayizi abahlukahlukene.Ngaphezu kokulungisa izingxenye ezincane ezihlukahlukene, umsebenzi oyinhloko webhodi lesifunda eliphrintiwe ukuxhuma ngogesi izingxenye ezihlukahlukene ezingenhla.
3. Ukukubeka kalula, isifunda esihlanganisiwe sihlanganisa isifunda senhloso evamile sibe yi-chip.Kuphelele.Uma isilimele ngaphakathi, i-chip nayo izolimala, futhi i-PCB ingakwazi ukudayisa izingxenye ngokwayo.Uma iphukile, ingashintshwa.isici.
I-PCB iyibhodi lesifunda eliphrintiwe, elibizwa ngokuthi ibhodi eliphrintiwe, futhi ingenye yezingxenye ezibalulekile embonini ye-electronics.Cishe zonke izinhlobo zemishini ye-elekthronikhi, kusukela kumawashi e-elekthronikhi kanye nezibali kuya kumakhompiyutha, okokusebenza kwe-elekthronikhi, nezinhlelo zezikhali zempi, inqobo nje uma kukhona izingxenye ze-elekthronikhi ezifana namasekethe ahlanganisiwe, ukuze kwenziwe ukuxhumana kukagesi phakathi kwezingxenye ezahlukahlukene, isekethe ephrintiwe. amabhodi kufanele asetshenziswe.ipuleti.
Ibhodi lesifunda eliphrintiwe lakhiwe i-insulating base plate, izintambo ezixhumayo namaphedi okuhlanganisa nokushisela izingxenye ze-elekthronikhi, futhi linemisebenzi emibili yomugqa wokuqhuba kanye ne-insulating base plate.Ingakwazi ukuvala izintambo eziyinkimbinkimbi futhi ibone ukuxhumana kukagesi phakathi kwezingxenye ezisesekethe, okungagcini nje ukwenza kube lula ukuhlanganisa nokushisela imikhiqizo ye-elekthronikhi, kunciphisa umthwalo wezintambo ezindleleni zendabuko, futhi kunciphisa kakhulu umfutho wezisebenzi;futhi kunciphisa ubukhulu bomshini wonke.Ivolumu, yehlisa izindleko zomkhiqizo, yenza ngcono ikhwalithi nokuthembeka kwemishini kagesi.
Isekhethi ehlanganisiwe iyisisetshenziswa esincane sikagesi noma ingxenye.Ngokusebenzisa inqubo ethile, ama-transistors, ama-resistors, ama-capacitor, ama-inductors nezinye izakhi ezidingekayo kusekethe ziyaxhunywa, futhi zenziwa kuma-wafers amancane ama-semiconductor amancane noma ama-dielectric substrates, abese ehlanganiswa eshubhu., futhi ibe i-microstructure enemisebenzi edingekayo yesekethe;zonke izingxenye ezikuyo zihlanganiswe ngesakhiwo, okwenza izingxenye ze-elekthronikhi zibe yisinyathelo esikhulu ekufezeni i-miniaturization, ukusetshenziswa kwamandla okuphansi, ukuhlakanipha nokuthembeka okuphezulu.Imelwe ngohlamvu “IC” kusekethe.Abaqambi besekethe edidiyelwe amasekethe ahlanganisiwe asekelwe ku-Jack Kilby (germanium (Ge)) kanye no-Robert Noyce (i-silicon (Si)-based based circuits).Iningi lemboni ye-semiconductor yanamuhla isebenzisa amasekethe ahlanganisiwe asuselwa ku-silicon.
