Izinhlobo zamaphedi e-PCB
1. Iphedi yesikwele Ivame ukusetshenziswa lapho izingxenye ebhodini eliphrintiwe zinkulu futhi zimbalwa, futhi umugqa ophrintiwe ulula. Uma wenza i-PCB ngesandla, ukusebenzisa le pad kulula ukufeza i-2.Round pad Isetshenziswa kakhulu kumabhodi aphrintiwe ohlangothini olulodwa nakabili, izingxenye zihlelwa ngokujwayelekile...Funda kabanzi -
I-Counterbore
Izimbobo zokubala zibhojwa ebhodini lesifunda ngenaliti yokubhoboza ikhanda eliyisicaba noma ummese we-gong, kodwa azikwazi ukubhobozwa (okungukuthi, phakathi kwezimbobo). Ingxenye yoguquko phakathi kodonga lwembobo ku-diameter yembobo engaphandle/enkulu kunawo wonke kanye nodonga lwembobo kububanzi bembobo encane kakhulu ihambisana...Funda kabanzi -
Iyini indima yomugqa wamathuluzi nge-PCB?
Enqubweni yokukhiqiza ye-PCB, kunenye inqubo ebalulekile, okungukuthi, i-tooling strip. Ukubhukha unqenqema lwenqubo kubaluleke kakhulu ekucubungulweni kwesichibi se-SMT okulandelayo. Uhlu lwamathuluzi luyingxenye engezwe nhlangothi zombili noma izinhlangothi ezine zebhodi le-PCB, ikakhulukazi ukusiza i-SMT p...Funda kabanzi -
Ukwethulwa kwe-Via-in-Pad:
Ukwethulwa kwe-Via-in-Pad: Kuyaziwa ukuthi i-vias (VIA) ingahlukaniswa ihlukaniswe ngembobo, imbobo eyimpumputhe futhi igqitshwe nge-vias hole, enemisebenzi ehlukene. Ngokuthuthukiswa kwemikhiqizo ye-elekthronikhi, i-vias idlala indima ebalulekile ekuxhumaneni kwe-interlayer yesekethe ephrintiwe ...Funda kabanzi -
Idizayini ye-DFM yesikhala sokukhiqiza se-PCB
Isikhala sokuphepha kukagesi sincike ikakhulukazi ezingeni lemboni yokwenza amapuleti, ngokuvamile angu-0.15mm. Eqinisweni, kungase kusondele nakakhulu. Uma isifunda singahlobene nesignali, inqobo nje uma kungekho isifunda esifushane futhi yamanje yanele, i-current enkulu idinga izintambo ezinkulu ...Funda kabanzi -
Izindlela Eziningana Zokuhlola ze-PCBA Board Short Circuit
Enqubweni yokucubungula i-chip ye-SMT, ukujikeleza okufushane kuyinto evamile kakhulu yokucubungula okubi. Ibhodi lesekhethi ye-PCBA elifushane alikwazi ukusetshenziswa ngokujwayelekile. Okulandelayo kuyindlela yokuhlola evamile yesifunda esifushane sebhodi le-PCBA. 1. Kunconywa ukusebenzisa i-short circuit positi...Funda kabanzi -
Idizayini yokwenziwa yebanga lokuphepha likagesi le-PCB
Kunemithetho eminingi yokuklama ye-PCB. Okulandelayo yisibonelo sezikhala zokuphepha zikagesi. Ukusetha umthetho kagesi ibhodi lesifunda sokuklama ku-wiring kufanele lihambisane nemithetho, okuhlanganisa ibanga lokuphepha, isekethe evulekile, ukulungiselelwa kwesekethe emfushane. Ukulungiselelwa kwalawa mapharamitha kuzothinta...Funda kabanzi -
Amaphutha ayishumi enqubo yokuklama ibhodi lesifunda se-PCB
Amabhodi esekethe e-PCB asetshenziswa kabanzi emikhiqizweni ehlukahlukene ye-elekthronikhi ezweni lanamuhla elithuthukile ezimbonini. Ngokusho kwezimboni ezahlukene, umbala, umumo, usayizi, ungqimba, kanye nempahla yamabhodi wesifunda se-PCB ahlukile. Ngakho-ke, ulwazi olucacile luyadingeka ekwakhiweni kwe-PCB circui...Funda kabanzi -
Liyini izinga le-warpage le-PCB?
Eqinisweni, i-PCB warping iphinde ibhekisele ekugobeni kwebhodi lesifunda, okubhekiselwe ebhodini lesekethe lokuqala. Uma ibekwe kudeskithophu, iziphetho ezimbili noma phakathi kwebhodi zivela kancane phezulu. Lesi simo saziwa ngokuthi yi-PCB warping embonini. Ifomula yokubala i-t...Funda kabanzi -
Yiziphi izidingo laser welding inqubo PCBA design?
1.Umklamo Wokwenziwa Kwe-PCBA Idizayini yokwenziwa kwe-PCBA ixazulula inkinga yokuhlangana, futhi inhloso ukuzuza indlela emfishane yenqubo, izinga lokuphasa eliphezulu kakhulu, kanye nezindleko zokukhiqiza eziphansi kakhulu. Okuqukethwe kokuklama kufaka phakathi: ...Funda kabanzi -
Idizayini yokwenziwa yesakhiwo se-PCB nezintambo
Mayelana nokuhlelwa kwe-PCB nenkinga yezintambo, namuhla ngeke sikhulume ngokuhlaziywa kobuqotho besignali (SI), ukuhlaziywa kokuhambisana kwe-electromagnetic (EMC), ukuhlaziywa kobuqotho bamandla (PI). Ngikhuluma nje ngohlaziyo lwe-manufacturability analysis (DFM), ukwakheka okungenangqondo kokwenziwa nakho kuzoholela...Funda kabanzi -
Ukucubungula kwe-SMT
Ukucubungula kwe-SMT kuwuchungechunge lobuchwepheshe benqubo yokucubungula ngesisekelo se-PCB. Inezinzuzo zokunemba okuphezulu nokushesha okusheshayo, ngakho-ke yamukelwe abakhiqizi abaningi be-elekthronikhi. Inqubo yokucubungula i-chip ye-SMT ikakhulukazi ihlanganisa isikrini sikasilika noma ukukhishwa kweglue, ukukhwezwa noma...Funda kabanzi
