Ukukhubazeka okungathi sína (okuchazwa njengokuthi CR): noma ikuphi ukonakala okwanele ukubangela ukulimala emzimbeni womuntu noma umshini noma ukubeka engcupheni ukuphepha kwempilo, njengalokhu: ukungalandeli imithetho yezokuphepha / ukushiswa / ugesi ukushaqeka....Funda kabanzi -
Yiziphi Izinto Okufanele Sizicabangele Lapho Sikhetha Umhlinzeki Webhodi Lesekethe?
Lapho ukhetha umphakeli webhodi lesifunda, kubalulekile ukucabangela izici eziningana ukuze uqinisekise ukuthi uthola umkhiqizo wekhwalithi engcono kakhulu ngentengo efanelekile.Nazi ezinye zezinto okufanele uzikhumbule: Ikhwalithi Yamazinga Ekhwalithi ingenye yezinto ezibaluleke kakhulu okufanele zicatshangelwe ...Funda kabanzi -
Yiziphi Izimpawu Ze-PCB Cleaners?
Ngokucatshangelwa ezicini ze-ejenti yokuhlanza, abantu bavame ukukhetha i-trichlorotrifluoroethane (CFC-113) ne-methyl chloroform njengento eyinhloko ye-ejenti yokuhlanza. I-CFC-113 inezinzuzo zokusebenza kahle kokuwohloka okuphezulu, amandla aqinile okuncibilika ensalela eguquguqukayo, engeyona- ezinobuthi, ezingezona fla...Funda kabanzi -
Idizayini ye-PCB ye-prototyping ngokusebenzisa isilinganiso nezindlela zokuklama ezisebenza kahle (2)
5. I-wiring ye-manual kanye nokuphathwa kwezimpawu ezibucayi Nakuba leli phepha ligxile ekufakeni izintambo ezizenzakalelayo, kodwa i-wiring manual esikhathini samanje nangesikhathi esizayo kuyinqubo ebalulekile yokuklama ibhodi lesifunda eliphrintiwe.Ukusetshenziswa kwezintambo ezenziwa ngesandla kusiza amathuluzi ezintambo ezizenzakalelayo ukuze aqedele umsebenzi wokufaka izintambo.Ngokunganaki...Funda kabanzi -
I-PCB Prototyping Design Ngokusebenzisa Izinga kanye Namasu Okusebenza Kahle Komklamo (1)
Idizayini yezintambo ze-PCB, yokuthuthukisa indwangu ngesilinganiso sesethi ephelele yezindlela, lapha, ukukunikeza nge-PCB design ukuze uthuthukise izinga lendwangu ngesilinganiso sokusebenza kahle komklamo kanye namasu aphumelelayo, hhayi kuphela kumakhasimende okusindisa umjikelezo wokuthuthukiswa kwephrojekthi, kodwa futhi ...Funda kabanzi -
I-PCB Isakhiwo se-CAD Software
Uhlolojikelele Lwesakhiwo se-PCB I-CAD Software PCB i-software ye-CAD iyithuluzi elibalulekile lokuklama amabhodi esekethe aphrintiwe.Ivumela abaklami ukuthi bakhe ama-schematics nezakhiwo zebhodi, izingxenye zendawo, izintambo zomzila futhi bakhiqize amafayela okukhiqiza.Ngokuhamba kweminyaka, isoftware ye-PCB layout CAD isiye yahlanganisa...Funda kabanzi -
