Uyini umehluko phakathi kokufakwa kwegolide nesiliva ku-PCB?
Abadlali abaningi be-DIY bazothola ukuthi imibala ye-PCB esetshenziswa imikhiqizo ehlukahlukene yebhodi emakethe iyakhazimula. Imibala evame kakhulu ye-PCB emnyama, eluhlaza, eluhlaza okwesibhakabhaka, ephuzi, ensomi, ebomvu nensundu. Abanye abakhiqizi bathuthukise ngobuhlakani ama-PCB emibala ehlukene njengomhlophe nopinki. Kwezamasiko...Funda kabanzi -
Zifundise ukuthi ungahlulela kanjani ukuthi i-PCB ingeyeqiniso
-PCBworld Ukushoda kwezinto zikagesi kanye nokunyuka kwentengo. Inikeza amathuba kubazenzisi. Kulezi zinsuku, izakhi ze-elekthronikhi ezingamanga sezidumile. Ama-fake amaningi afana nama-capacitor, resistors, inductors, amashubhu e-MOS, namakhompyutha e-single-chip azungeza...Funda kabanzi -
Kungani uxhuma ama-vias e-PCB?
Imbobo yokuqhuba i-Via hole yaziwa nangokuthi ngembobo. Ukuze kuhlangatshezwane nezidingo zamakhasimende, ibhodi lesekhethi ngembobo kufanele lixhunywe. Ngemuva kokuzijwayeza okuningi, inqubo yendabuko yokuxhuma i-aluminium iyashintshwa, futhi imaski yebhodi lesifunda ye-solder kanye nokuxhuma kuqedwa ngami mhlophe...Funda kabanzi -
Ukungaqondi kahle 4: Idizayini yamandla aphansi
Iphutha elivamile 17: Lezi zimpawu zebhasi zonke zidonswa ngabaphikisi, ngakho-ke ngizizwa ngikhululekile. Isixazululo esihle: Ziningi izizathu zokuthi kungani amasignali kudingeka adonswe phansi naphezulu, kodwa akuwona wonke adinga ukudonswa. I-resistor yokudonsa nokudonsa phansi idonsa isignali yokufaka elula, futhi yamanje incane...Funda kabanzi -
Qhubeka usuka Esahlukweni Esidlule: Ukungaqondi 2: Idizayini Yokwethembeka
Iphutha elivamile lesi-7: Leli bhodi elilodwa likhiqizwe ngamaqoqo amancane, futhi azikho izinkinga ezitholakele ngemva kwesikhathi eside sokuhlolwa, ngakho-ke asikho isidingo sokufunda incwadi ye-chip. Iphutha Elivamile 8: Angikwazi ukusolwa ngamaphutha okusebenza komsebenzisi. Isixazululo esihle: Kulungile ukudinga ukuthi umsebenzisi...Funda kabanzi -
Onjiniyela bakagesi bavame ukwenza amaphutha (1) Zingaki izinto ongazenzanga kahle?
Ukungaqondi kahle 1: Ukonga izindleko Iphutha elivamile 1: Imuphi umbala okufanele isikhombisi sikhanyise iphaneli? Mina ngokwami ngincamela okuluhlaza okwesibhakabhaka, ngakho-ke kukhethe. Isixazululo esihle: Izibani zenkomba emakethe, ezibomvu, eziluhlaza okotshani, eziphuzi, eziwolintshi, njll., kungakhathalekile ukuthi zingakanani (ngaphansi kuka-5MM) nokupakishwa kwazo, zine...Funda kabanzi -
Okufanele ukwenze uma i-PCB ikhubazekile
Ebhodini lokukopisha le-pcb, ukunganaki okuncane kungase kubangele ukuba ipuleti elingezansi liwohloke. Uma ingathuthukisiwe, izothinta ikhwalithi nokusebenza kwebhodi lekhophi ye-pcb. Uma ilahlwa ngokuqondile, izobangela ukulahlekelwa kwezindleko. Nazi ezinye izindlela zokulungisa ukuwohloka kwepuleti eliphansi. ...Funda kabanzi -
Iqhinga elincane lokuhlola i-multimeter yezingxenye ze-SMT
Ezinye izakhi ze-SMD zincane kakhulu futhi akulula ukuzihlola futhi zilungiswe ngamapeni ajwayelekile e-multimeter. Enye iwukuthi kulula ukubangela isifunda esifushane, kanti enye iwukuthi ayihambisani nebhodi lesifunda eliboshwe nge-insulating coating ukuze lithinte ingxenye yensimbi yephini lengxenye.

Ukuhlaziywa kwamaphutha kagesi ngezikhathi ezinhle nezikhathi ezimbi
Ngokuphathelene namathuba, amaphutha ahlukahlukene kagesi anezikhathi ezinhle nezimbi ahlanganisa lezi zimo ezilandelayo: 1. Ukuthintana okungalungile Ukuthintana okungalungile phakathi kwebhodi ne-slot, lapho ikhebula liphuka ngaphakathi, ngeke lisebenze, ipulaki kanye netheminali yocingo kukhona. awuxhumani, futhi izingxenye ...Funda kabanzi -
Izimpawu nokwahlulela komonakalo wokumelana
Kuvame ukubonakala ukuthi abaqalayo abaningi baphonsa ukumelana ngenkathi belungisa umjikelezo, futhi idilizwa futhi ihlanganiswe. Eqinisweni, isilungiswe kakhulu. Inqobo nje uma uqonda izici zomonakalo zokumelana, akudingekile ukuba uchithe isikhathi esiningi. Ukumelana ku ...Funda kabanzi -
pcb e ikhono panel
1. Uhlaka lwangaphandle (uhlangothi olubambayo) lwejigsaw ye-PCB kufanele lusebenzise idizayini evaliwe ye-loop ukuze kuqinisekiswe ukuthi ijigsaw ye-PCB ngeke yonakale ngemva kokulungiswa ku-fixture; 2. Ububanzi bephaneli ye-PCB ≤260mm (umugqa we-SIEMENS) noma ≤300mm (umugqa we-FUJI); uma kudingeka ukusabalalisa okuzenzakalelayo, ububanzi bephaneli ye-PCB nobude ≤...Funda kabanzi -
