I-Vias ebhodini lesekethe ibizwa ngokuthi i-vias, ehlukaniswe ngemigodi, imigodi eyimpumputhe kanye nezimbobo ezigqitshiwe (i-HDI Circuit Board).Ngokuyinhloko zisetshenziselwa ukuxhuma izintambo ezingqimbeni ezihlukene zenethiwekhi efanayo futhi ngokuvamile azisetshenziswa njengezingxenye ze-soldering;Amaphedi ebhodini lesifunda abizwa ngokuthi ama-pads, ahlukaniswe abe ama-pin pads kanye nama-surface mount pads;amaphinikhodi anezimbobo ze-solder, okuyi...
- Isingeniso sokucutshungulwa kwe-plasma kumabhodi e-PCB
Ngokufika kweminyaka yolwazi lwedijithali, izimfuneko zokuxhumana okufika phezulu, ukudluliswa kwesivinini esikhulu, kanye nokuba yimfihlo okuphezulu kwezokuxhumana ziya ngokuya ziba phezulu.Njengomkhiqizo osekelayo obalulekile embonini yobuchwepheshe bolwazi lwe-elekthronikhi, i-PCB idinga i-substrate ukuthi ihlangabezane nokusebenza kwe-dielectric engaguquki, into ephansi yokulahlekelwa kwemidiya, izinga lokushisa eliphezulu...
- Ungalithola kanjani ibhodi le-PCB elihle?
Ukuthuthukiswa okusheshayo kwezimboni zamaselula, ze-electronics, nezokuxhumana kukhuthaze ukukhula okuqhubekayo kanye nokukhula ngokushesha kwemboni yebhodi lesifunda le-PCB.Abantu banezidingo ezengeziwe zenani lezendlalelo, isisindo, ukunemba, izinto zokwakha, imibala, nokuthembeka kwezingxenye.Kodwa-ke, ngenxa yokuncintisana kwentengo yemakethe, izindleko zezinto zebhodi le-PCB nazo zikhuphuka kakhulu ...
- Ama-PCB Amnyama Angcono KuneGreen?
Okokuqala, njengebhodi lesifunda eliphrintiwe, i-PCB ihlinzeka ngokuxhumana phakathi kwezingxenye ze-elekthronikhi.Abukho ubuhlobo obuqondile phakathi kombala nokusebenza, futhi umehluko we-pigments akuphazamisi izakhiwo zikagesi.Ukusebenza kwebhodi le-PCB kunqunywa izinto ezifana nezinto ezisetshenzisiwe (inani eliphezulu le-Q), ukwakheka kwezintambo, kanye nezingqimba ezimbalwa ze-t...
- Ubuchwepheshe bebhodi lesekethe lokunemba okuphezulu
Ibhodi lesifunda elinembayo eliphakeme libhekisela ekusetshenzisweni kobubanzi/isikhala somugqa ocolekile, izimbobo ezincane, ububanzi obuncane bendandatho (noma ukungabi nobubanzi bendandatho), kanye nezimbobo ezigqitshiwe nezingaboni ukuze kuzuzwe ukuminyana okuphezulu.Futhi ukunemba okuphezulu kusho ukuthi umphumela "womncane, omncane, omncane, omncane" uzoletha izidingo zokunemba okuphezulu nakanjani, thatha ububanzi bomugqa njengesibonelo: O. 20mm ububanzi bomugqa, ngokuvumelana nemithethonqubo yokukhiqiza i-O. 16...
- I-PTH Yebhodi Lesekethe Eliphrintiwe
Izinto eziyisisekelo zebhodi lesifunda lefektri ye-electro-acoustic PCB ine-foil yethusi kuphela ezinhlangothini zombili, futhi phakathi nendawo iyisendlalelo sokuvikela, ngakho-ke akudingeki ukuba ibe yi-conductive phakathi kwezinhlangothi ezimbili noma izifunda ezinezingqimba eziningi zesekethe. ibhodi?Imigqa ezinhlangothini zombili ingaxhunywa kanjani ndawonye ukuze i-current ihambe kahle?Ngezansi, sicela ubone i-electroacoustic PCB manufactu...
- Izinto Eziningana Eziyisisekelo Ezithinta Inqubo Yokugcwalisa Imbobo Ye-Electroplating Ekukhiqizeni Kwe-PCB
Inani lokukhiphayo lomkhakha we-electroplating PCB womhlaba wonke likhule ngokushesha kunani eliphelele lokuphumayo lemboni yezingxenye ze-elekthronikhi.Yimboni enengxenye enkulu kunazo zonke embonini yokuhlukanisa izingxenye ze-elekthronikhi futhi inesikhundla esiyingqayizivele.Inani lokukhiphayo lonyaka le-electroplating PCB lingama-dollar ayizigidi eziyizinkulungwane ezingama-60.Umthamo wemikhiqizo kagesi uya ngokuya ukhula...
- Ungazi kanjani ungqimba lwe-pcb?
Lenziwa kanjani ibhodi lesifunda lefekthri ye-PCB?Izinto ezincane zesekethe ezingabonwa phezulu ziyi-copper foil.Ekuqaleni, i-foil yethusi yayimbozwe kuyo yonke i-PCB, kodwa ingxenye yayo yaqoshwa ngesikhathi senqubo yokukhiqiza, futhi ingxenye esele yaba yisekethe encane efana ne-mesh..Lezi zintambo zibizwa ngokuthi izintambo noma izintambo futhi zisetshenziselwa ukuhlinzeka ngoxhumano lukagesi...
