Ake sibheke pcb board design kanye pcba
Ngikholwa ukuthi baningi abantu abanjaloajwayelekilengomklamo webhodi le-pcb futhi angase azizwe kaningi ekuphileni kwansuku zonke, kodwa angase angazi okuningi nge-PCBA futhi adideke namabhodi wesifunda aphrintiwe.Ngakho-ke uyini umklamo webhodi le-pcb?I-PCBA yavela kanjani?Ihluke kanjani ku-PCBA?Ake sibhekisise.
*Mayelana nomklamo webhodi le-pcb*
Ngenxa yokuthi yenziwe nge-electronic printing, ibizwa ngokuthi ibhodi lesifunda "eliphrintiwe".Ibhodi le-pcb liyingxenye ebalulekile ye-elekthronikhi embonini ye-elekthronikhi, ukusekela izingxenye ze-elekthronikhi, kanye nesithwali sokuxhuma kagesi kwezingxenye ze-elekthronikhi.Amabhodi e-PCB asetshenziswe kabanzi ekukhiqizeni nasekukhiqizeni imikhiqizo kagesi.Izici zayo eziyingqayizivele zingafingqwa ngale ndlela elandelayo:
1. Ubuningi bezintambo eziphakeme, usayizi omncane kanye nesisindo esincane kuhambisana ne-miniaturization yemishini kagesi.
2. Ngenxa yokuphindaphinda nokuvumelana kwehluzo, amaphutha ezintambo nokuhlanganisa ayancishiswa, futhi isikhathi sokugcinwa kwemishini, ukulungisa iphutha nokuhlolwa sigcinwa.
3. Kuyazuzisa ukukhiqizwa kwemishini nokuzenzakalelayo, ukuthuthukisa ukukhiqizwa kwezabasebenzi, nokunciphisa izindleko zemishini kagesi.
4. Idizayini ingalinganiswa ukuze kube lula ukushintshana.
*Mayelana ne-PCBA*
I-PCBA isifinyezo sebhodi lesifunda + eliphrintiwe, okusho ukuthi, i-PCBA iyinqubo yonke yokunamathisela ingxenye engenhla yebhodi elingenalutho lebhodi lesifunda eliphrintiwe kanye nokucwiliswa.
QAPHELA: I-Surface mount ne-die mount zombili izindlela zokuhlanganisa amadivayisi ebhodini lesekethe eliphrintiwe.Umehluko omkhulu ukuthi ubuchwepheshe bokukhuphuka komhlaba akudingi izimbobo zokumba ebhodini lesifunda eliphrintiwe, izikhonkwane zengxenye zidinga ukufakwa emigodini yokubhoboza ye-DIP.
Ubuchwepheshe bokukhweza i-Surface Mount Technology (SMT) busebenzisa umshini wokukhetha nendawo ukuze kugxunyekwe izingxenye ezithile ebhodini lesekethe eliphrintiwe.Inqubo yayo yokukhiqiza ihlanganisa ukuma kwe-PCB, ukuphrinta kwe-solder paste, ukufakwa komshini wokubeka, i-oven yokugeleza kabusha kanye nokuhlolwa kokukhiqiza.
Ama-DIP angama-“plug-ins”, okusho ukufaka izingxenye ebhodini lesekethe eliphrintiwe.Lezi zingxenye zinkulu ngosayizi futhi azifaneleki ubuchwepheshe bokufaka futhi zihlanganiswe ngendlela yama-plug-ins.Izinqubo zokukhiqiza eziyinhloko yilezi: ukunamathela, i-plug-in, ukuhlola, i-wave soldering, i-brush plating kanye nokuhlolwa kokukhiqiza.
*Umehluko phakathi kwama-PCB nama-PCBA*
Kusukela kusingeniso esingenhla, singakwazi ukwazi ukuthi i-PCBA ngokuvamile ibhekisela kunqubo yokucubungula, futhi ingaqondwa njengebhodi lesifunda eliqediwe.I-PCBA ingabalwa kuphela ngemva kokuba zonke izinqubo ebhodini lesekethe eliphrintiwe seziqediwe.Ibhodi lesifunda eliphrintiwe liyibhodi lesifunda eliphrintiwe elingenalutho elingenazo izingxenye kulo.
