Isekhethi Ephrintiwe Eguquguqukayo
I-Flexible Printed Circuit Flexible Printed Circuit，Ingagotshwa, ilimale futhi isongwe ngokukhululeka.Ibhodi lesifunda eliguquguqukayo licutshungulwa kusetshenziswa ifilimu ye-polyimide njengento eyisisekelo.Ibuye ibizwe ngebhodi elithambile noma i-FPC embonini.Ukugeleza kwenqubo yebhodi lesifunda eliguquguqukayo kuhlukaniswe kabili-...Funda kabanzi -
Imbangela ye-PCB ewa ipuleti le-solder
Imbangela PCB falling solder ipuleti PCB wesifunda ibhodi inqubo ukukhiqizwa, ngokuvamile ukuhlangabezana ezinye amaphutha inqubo, ezifana PCB wesifunda ibhodi ibhodi wire off ezimbi (futhi ngokuvamile kuthiwa ukujikijela ithusi), kuthinta izinga lomkhiqizo.Izizathu ezijwayelekile zokuphonsa ibhodi lesifunda le-PCB zimi kanje:...Funda kabanzi -
Ungabhekana kanjani nomugqa wokuhlukanisa isignali ye-PCB?
Enqubweni yokuklama kwe-PCB, ukuhlukaniswa kwendiza yamandla noma ukuhlukaniswa kwendiza ephansi kuzoholela endizeni engaphelele.Ngale ndlela, lapho isignali ihanjiswa, indiza yayo eyinkomba izosuka kwelinye indiza yamandla iye kwenye indiza yamandla.Lesi simo sibizwa ngokuthi ukuhlukaniswa kwe-signal span....Funda kabanzi -
Ingxoxo ngenqubo yokugcwalisa imbobo ye-PCB ye-electroplating
Usayizi wemikhiqizo ye-elekthronikhi uya uba mncane futhi ube mncane, futhi ukunqwabelanisa ngokuqondile nge-vias eyimpumputhe kuyindlela yokuklama yokuxhumanisa okuphezulu.Ukwenza umsebenzi omuhle wokupakisha izimbobo, okokuqala, ukugcwala phansi komgodi kufanele kwenziwe kahle.Kukhona abakhiqizi abaningi...Funda kabanzi -
Iyini i-copper cladding?
I-1.I-Copper cladding Okubizwa ngokuthi i-copper coating, yindawo engenzi lutho ebhodini lesifunda njenge-datum, bese igcwaliswa ngethusi eliqinile, lezi zindawo zethusi zaziwa nangokuthi ukugcwalisa ithusi.Ukubaluleka kokugqoka kwethusi yilokhu: ukunciphisa i-impedance yomhlabathi, ukuthuthukisa ikhono lokulwa nokuphazamiseka;Yehlisa i-volt...Funda kabanzi -
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.
