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 njengelo 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
—-Kusuka ku-PCBWorld Umhlangano Wesine Wabaholi BeSivumelwano Esibanzi SesiFunda Sokubambisana Kwabaholi Ubanjwe ngoNovemba 15. Amazwe ayishumi e-ASEAN namazwe angu-15 ahlanganisa i-China, Japan, South Korea, Australia, ne-New Zealand asayine ngokusemthethweni Ingxenye Yezomnotho Ephelele Yesifunda...Funda kabanzi -
Ungayisebenzisa kanjani i-"multimeter" ukuxazulula inkinga yebhodi lesifunda
Umthofu wokuhlola obomvu usekelwe phansi, izikhonkwane ezisendingilizini ebomvu zonke ziyizindawo, futhi izigxobo ezingezinhle zama-capacitor ziyizindawo. Faka 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 -
Lokhu kuthuthukisa inqubo yokukhiqiza ye-PCB futhi kungakhuphula inzuzo!
Kuningi ukuncintisana embonini yokukhiqiza ye-PCB. Wonke umuntu ufuna ukuthuthukiswa okuncane ukuze abanike inzuzo. Uma ubonakala ungakwazi ukuhambisana nenqubekelaphambili, kungenzeka ukuthi inqubo yakho yokukhiqiza isolwe. Ukusebenzisa lezi zindlela ezilula kungenza kube lula...Funda kabanzi -
Ungayenza kanjani i-PCB batch encane, uhlelo lokukhiqiza oluhlukahlukene?
Ngokudlondlobala kokuncintisana kwezimakethe, indawo yemakethe yamabhizinisi esimanje ibe nezinguquko ezinkulu, futhi ukuncintisana kwebhizinisi kuya kugcizelela ukuncintisana okusekelwe ezidingweni zamakhasimende. Ngakho-ke, izindlela zokukhiqiza zamabhizinisi kancane kancane zishintshele ezinhlobonhlobo...Funda kabanzi -
Imithetho yesitaki ye-PCB
Ngokuthuthukiswa kobuchwepheshe be-PCB kanye nokwanda kwesidingo sabathengi semikhiqizo esheshayo nenamandla, i-PCB isishintshile isuka ebhodini elinezingqimba ezimbili ukuya ebhodini elinezingqimba ezine, eziyisithupha kanye nezingqimba ezifika kweziyishumi kuya kwezingamashumi amathathu ze-dielectric nama-conductor. .
