Ubudlelwano obuyisisekelo phakathi kwesakhiwo ne-PCB 2
Ngenxa yezimpawu zokushintsha kwamandla kagesi, kulula ukubangela ukushintshwa kwamandla kagesi ukukhiqiza ukuphazamiseka okukhulu kokuhambisana kwe-electromagnetic.Njengonjiniyela wokuphakela amandla, unjiniyela ohambelana nogesi, noma unjiniyela wesakhiwo se-PCB, kufanele uqonde i-cau...Funda kabanzi -
Kunobudlelwane obuyisisekelo obufika ku-29 phakathi kwesakhiwo ne-PCB!

Zingaki izinhlobo ze-PCB zebhodi lesifunda ezingahlukaniswa ngokwezinto ezibonakalayo?Zisetshenziswa kuphi?
Isigaba sezinto ezibonakalayo ze-PCB ikakhulukazi sihlanganisa lokhu okulandelayo: i-bai isebenzisa i-FR-4 (isisekelo sendwangu yengilazi ye-fiber), i-CEM-1/3 (i-glass fiber kanye ne-substrate eyinhlanganisela yephepha), i-FR-1 (i-copper-clad clad laminate), isisekelo sensimbi. Ama-laminates ane-Copper clad (ikakhulukazi asekelwe ku-aluminium, ambalwa asekelwe ensimbi) yiwona ...Funda kabanzi -
Igridi yethusi noma ithusi eliqinile?Lena inkinga ye-PCB okufanele ucabange ngayo!
Liyini ithusi?Okubizwa ngokuthi ukuthululela kwethusi ukusebenzisa indawo engasetshenziswanga ebhodini lesifunda njengendawo yokubhekisela bese uyigcwalisa ngethusi eliqinile.Lezi zindawo zethusi zibizwa nangokuthi ukugcwaliswa kwethusi.Ukubaluleka kwe-copper coating ukunciphisa i-impedance yocingo oluphansi kanye nokwenza ngcono ...Funda kabanzi -
Ngezinye izikhathi kunezinzuzo eziningi ku-PCB yethusi yokucwenga phansi
Enqubweni yokuklama ye-PCB, abanye onjiniyela abafuni ukubeka ithusi phezu kwawo wonke ungqimba olungezansi ukuze bonge isikhathi.Ingabe lokhu kulungile?Ingabe i-PCB kufanele ifakwe i-copper plated?Okokuqala, sidinga ukucaca: i-copper plating engezansi inenzuzo futhi iyadingeka ku-PCB, kodwa ...Funda kabanzi -
Izici ezine eziyisisekelo zesekethe ye-PCB RF
Lapha, izici ezine eziyisisekelo zamasekhethi efrikhwensi yomsakazo zizohunyushwa kusukela ezicini ezine: isixhumi esibonakalayo sefrikhwensi yomsakazo, isignali encane efiselekayo, isignali enkulu yokuphazamiseka, nokuphazamiseka kwesiteshi esiseduze, kanye nezici ezibalulekile ezidinga ukunakwa okukhethekile enqubweni yokuklama ye-PCB. .Funda kabanzi -
Ibhodi lephaneli yokulawula
Ibhodi lokulawula liphinde libe uhlobo lwebhodi lesifunda.Nakuba uhla lwayo lokusebenza lungebanzi njengalelo lamabhodi esekethe, luhlakaniphe futhi luzenzakalela kakhulu kunamabhodi esekethe ajwayelekile.Kalula nje, ibhodi lesifunda elingadlala indima yokulawula lingabizwa ngokuthi ibhodi lokulawula.Iphaneli yokulawula i...Funda kabanzi -
I-RCEP enemininingwane: Amazwe ayi-15 ajoyina izandla ukuze akhe umbuthano wezomnotho omkhulu

Ungayisebenzisa kanjani i-"multimeter" ukuxazulula inkinga yebhodi lesifunda
Umthofu wokuhlola obomvu usekelwe phansi, izikhonkwane ezisendingilizini ebomvu zonke ziyizindawo, futhi izigxobo ezingezinhle zama-capacitor ziyizindawo.Beka i-black test lead kuphinikhodi ye-IC ukuze ikalwe, bese i-multimeter izobonisa inani le-diode, futhi yahlulele ikhwalithi ye-IC ngokusekelwe ku-diode val...Funda kabanzi -
Ubuchwepheshe bokuhlola obujwayelekile kanye nemishini yokuhlola embonini ye-PCB
Kungakhathaliseki ukuthi hlobo luni lwebhodi lesifunda eliphrintiwe elidinga ukwakhiwa noma ukuthi hlobo luni lwemishini esetshenziswayo, i-PCB kufanele isebenze kahle.Kuyisihluthulelo sokusebenza kwemikhiqizo eminingi, futhi ukwehluleka kungabangela imiphumela emibi.Ukuhlola i-PCB ngesikhathi sokuklama, ukukhiqiza, kanye nenqubo yokuhlanganisa ...Funda kabanzi -
Liyini ibhodi elingenalutho?Yiziphi izinzuzo zokuhlolwa kwebhodi elingenalutho?
Kalula nje, i-PCB engenalutho ibhekisela ebhodini lesifunda eliphrintiwe ngaphandle kwezimbobo noma izingxenye ze-elekthronikhi.Avame ukubizwa ngokuthi ama-PCB angenalutho futhi ngezinye izikhathi abuye abizwe ngokuthi ama-PCB.Ibhodi le-PCB elingenalutho lineziteshi eziyisisekelo kuphela, amaphethini, okokunamathela kwensimbi kanye ne-PCB substrate.Iyini ukusetshenziswa kwe-PC engenalutho ...Funda kabanzi -
Isitaki se-PCB
Umklamo onama-laminated ngokuyinhloko ulandela imithetho emibili: 1. Ungqimba lwezintambo ngalunye kufanele lube nongqimba oluseduze lwereferensi (ungqimba lwamandla noma lomhlabathi);2. Ungqimba lwamandla amakhulu oluseduze kanye nongqimba lomhlabathi kufanele kugcinwe ebangeni elincane ukuze kunikeze amandla amakhulu okuhlanganisa;Okulandelayo kubala isitaki esivela...Funda kabanzi
