Izinhlobo Ezine Zezinzwa Zokushisa Ezivamile
Izinzwa zokushisa zingobunye bobuchwepheshe obuvame ukusetshenziswa emikhiqizweni eminingi namuhla, njengezimoto, ugesi omhlophe kanye nemikhiqizo yezimboni.Ukuze wenze isilinganiso sokushisa esithembekile, kubaluleke kakhulu ukukhetha inzwa yokushisa efanele yohlelo lokusebenza.Ngaphansi...Funda kabanzi -
Izixwayiso Zenqubo Yokushisela Ibhodi
1. Ngaphambi kokuthi i-PCB ifake i-reflow oven welding, qinisekisa ukuthi amaphedi ezingxenye namabhodi wesekethe ayashisela (ahlanzekile, akukho ukungcola, akukho oxidation, njll.).2. Gqoka ama-antistatic caps lapho ucutshungulwa futhi ushiswa.3. Gqoka amagilavu e-ESD ngesikhathi sokushisela ukuze ugweme ukushaqeka kukagesi.4. Uma insimbi kagesi idinga...Funda kabanzi -
Umgomo Wokusebenza we-Cystal Oscillator
Isifinyezo se-crystal oscillator I-Crystal oscillator ibhekisela kusikwe esilucwecwana esisikwe ku-quartz crystal ngokusho kwe-azimuth Angle, i-quartz crystal resonator, ebizwa ngokuthi i-quartz crystal noma i-crystal oscillator;I-crystal element ene-IC engezwe ngaphakathi kwephakheji ibizwa nge-crystal oscillator.Ku...Funda kabanzi -
Imbangela Nesixazululo Sokuguqulwa Kwebhodi Le-PCB
Ukuhlanekezela kwe-PCB kuyinkinga evamile ekukhiqizweni kwe-PCBA ngobuningi, okuzoba nomthelela omkhulu ekuhlanganiseni nasekuhlolweni, okuholela ekungazinzi komsebenzi wesekethe ye-elekthronikhi, isifunda esifushane/ukwehluleka kwesekethe evulekile.Izimbangela ze-PCB deformation zimi kanje: 1. Izinga lokushisa lebhodi le-PCBA p...Funda kabanzi -
Umgomo Oyisisekelo we-BGA Rework Station
Isiteshi sokusebenza kabusha se-BGA siyisisetshenziswa esisebenzayo esisetshenziselwa ukulungisa izingxenye ze-BGA, esivame ukusetshenziswa embonini ye-SMT.Okulandelayo, sizokwethula isimiso esiyisisekelo sesiteshi sokusebenza kabusha se-BGA futhi sihlaziye izici ezibalulekile zokuthuthukisa izinga lokulungisa le-BGA.BGA rework station zingahlukaniswa co optical ...Funda kabanzi -
Yini Odinga Ukukwazi Nge-Selective Wave Soldering?
Izinhlobo zomshini okhethiwe we-wave soldering umshini wokugcwalisa i-wave okhethiwe uhlukaniswe ngezinhlobo ezimbili: i-wave soldering ekhethiwe engaxhunyiwe ku-inthanethi kanye ne-inthanethi ekhethiwe ye-wave soldering.I-wave soldering ekhethiwe engaxhunyiwe ku-inthanethi: okungaxhunyiwe ku-inthanethi kusho ukungaxhunyiwe ku-inthanethi nolayini wokukhiqiza.Umshini wokufafaza we-Flux kanye ne-welding machi ekhethiwe ...Funda kabanzi -
Kungani PCBA Board Deform?
Enqubweni yokugeleza kwe-ovini kahhavini kanye nomshini wokugcwalisa i-wave soldering, ibhodi le-PCB lizokhubazeka ngenxa yethonya lezici ezihlukahlukene, okuholela ekushiseleleni kwe-PCBA okubi.Sizomane sihlaziye imbangela yokuguqulwa kwebhodi le-PCBA.1.
