Imininingwane engu-12 yesakhiwo se-PCB, ingabe ukwenze kahle?
1. Isikhala phakathi kwamapheshana Isikhala phakathi kwezingxenye ze-SMD yinkinga onjiniyela okufanele bayinake ngesikhathi sokuhlela.Uma isikhala sincane kakhulu, kunzima kakhulu ukuphrinta unamathisele we-solder futhi ugweme ukuhlanganisa nokunamathisela.Izincomo zebanga zimi kanje ibanga ledivayisi...Funda kabanzi -
Iyini ifilimu yebhodi lesifunda?Isingeniso senqubo yokugeza yefilimu yebhodi lesifunda
Ifilimu iyinto ejwayelekile kakhulu yokukhiqiza eyisiza embonini yebhodi lesifunda.Isetshenziselwa ikakhulukazi ukudlulisa ihluzo, imaski ye-solder nombhalo.Izinga lefilimu lithinta ngqo ikhwalithi yomkhiqizo.Ifilimu iyifilimu, iyinguqulo yakudala yefilimu, manje evame ukusho i-fi...Funda kabanzi -
Idizayini ye-PCB engavamile
[VW PCBworld] I-PCB ephelele esiyibona ngeso lengqondo ivamise ukuba wunxande ojwayelekile.Nakuba imiklamo eminingi iwunxande ngempela, imiklamo eminingi idinga amabhodi esifunda anomumo ongajwayelekile, futhi izimo ezinjalo ngokuvamile akulula ukuziklama.Lesi sihloko sichaza indlela yokuklama ama-PCB anomumo ongajwayelekile.Namuhla...Funda kabanzi -
Ukulethwa kwebhodi lenkampani yenethiwekhi kunzima, okuzodala izinguquko efomini lokupakisha?.
01 Isikhathi sokulethwa kwebhodi lenkampani yenethiwekhi kunzima ukuxazulula, futhi imboni ye-OSAT iphakamisa ukushintsha ifomu lokupakisha Imboni yokupakisha nokuhlola ye-IC isebenza ngesivinini esigcwele.Izikhulu eziphezulu ze-outsourcing packaging and testing (OSAT) zasho ngokungananazi ukuthi ngo-2021 izilinganiso...Funda kabanzi -
Ukusebenzisa lezi zindlela ezi-4, i-PCB yamanje idlula i-100A
Idizayini evamile ye-PCB yamanje ayidluli ku-10A, ikakhulukazi kuma-electronics asendlini nabathengi, ngokuvamile ukusebenza okuqhubekayo ku-PCB akudluli u-2A.Kodwa-ke, eminye imikhiqizo yenzelwe izintambo zamandla, futhi okwamanje okuqhubekayo kungafinyelela cishe ku-80A.Uma kucatshangelwa ngokushesha...Funda kabanzi -
Uyazi ukuthi yiziphi izinzuzo ze-PCB enezinombolo ezilinganayo?
[VW PCBworld] Abaklami bangase badizayine amabhodi esekethe aphrintiwe anezinombolo ezingavamile (ama-PCB).Uma i-wiring ingadingi isendlalelo esengeziwe, kungani siyisebenzisa?Ingabe ukwehlisa izendlalelo ngeke kwenze ibhodi lesifunda libe mncane?Uma kunebhodi lesifunda elilodwa elincane, ngeke yini izindleko zibe phansi?Nokho, kwezinye izimo...Funda kabanzi -
Kungani izinkampani ze-PCB zithanda i-Jiangxi yokukhulisa umthamo nokudlulisa?
[VW PCBworld] Amabhodi esekethe aphrintiwe ayizingxenye ezibalulekile zokuxhuma nge-elekthronikhi zemikhiqizo kagesi, futhi aziwa ngokuthi “umama wemikhiqizo kagesi”.Amabhodi esekethe aphrintiwe asatshalaliswa kabanzi, ahlanganisa amathuluzi okuxhumana, amakhompyutha nama-peripherals, ...Funda kabanzi -
Uyini umehluko phakathi kokufakwa kwegolide nokufakwa kwesiliva ebhodini le-PCB?Imiphumela yayimangaza
Abadlali abaningi be-DIY bazothola ukuthi imikhiqizo ehlukahlukene yebhodi emakethe isebenzisa izinhlobonhlobo ezididayo zemibala ye-PCB.Imibala evame kakhulu ye-PCB emnyama, eluhlaza, eluhlaza okwesibhakabhaka, ephuzi, ensomi, ebomvu, nensundu.Abanye abakhiqizi baye bahlakulela imibala emhlophe, epinki neminye ehlukene ye-PCB.Ngokwesiko...Funda kabanzi -
Kungani i-PCB kufanele ixhunywe ngezimbobo?Ingabe kukhona ulwazi olwaziyo?
Imbobo yokuqhuba i-Via hole yaziwa nangokuthi ngembobo.Ukuze kuhlangatshezwane nezidingo zamakhasimende, ibhodi lesekethe ngembobo kufanele lixhunywe.Ngemuva kokuzijwayeza okuningi, inqubo yokuxhuma ye-aluminium yendabuko iyashintshwa, futhi imaski ye-solder yebhodi lesifunda kanye nokuxhuma kuqedwa nge-wh...Funda kabanzi -
Ngo-2021, isimo se-quo namathuba e-PCB yezimoto
Usayizi wemakethe yezimoto ye-PCB yasekhaya, ukusatshalaliswa kanye nesimo sokuncintisana 1.
