Ungqimba impedance ENIG PCB 6351

Ngemuva kokuthi i-PCB yenziwe emgodini wesigamu, ungqimba lwethini lubekwe onqenqemeni lomgodi nge-electroplating. Isendlalelo sikathayela sisetshenziswa njengongqimba oluvikelayo ukuqinisa ukumelana nezinyembezi nokuvikela ngokuphelele ungqimba lwethusi oluwela odongeni lomgodi. Ngakho-ke, ukukhiqizwa kokungcola enqubeni yokukhiqiza yebhodi lesifunda eliphrintiwe kuncishisiwe, futhi umthwalo wokuhlanza nawo wehlisiwe, ukuze kuthuthukiswe ikhwalithi ye-PCB eqediwe.

Ngemuva kokuphothulwa kokukhiqizwa kwe-PCB ejwayelekile yomgodi, kuzoba khona izigaxa zethusi ezinhlangothini zombili zomgodi, futhi amachips ethusi azobandakanyeka ohlangothini olungaphakathi lwengxenye yomgodi. Uhhafu wembobo usetshenziswa njenge-PCB yengane, indima yomgodi wesigamu isenqubo ye-PCBA, kuzothatha uhhafu wengane ye-PCB, ngokunikeza uhhafu wembobo wokugcwalisa ithini ukwenza uhhafu wepuleti eliyinhloko elifakwe ebhodini elikhulu , kanye nengxenye yomgodi onensimbi eyakhiwe ngethusi, izothinta ngqo uthini, kuthinte ukuwelda ngokuqinile kweshidi kubhodi yomama, futhi kuthinte ukubukeka nokusetshenziswa kwawo wonke umshini wokusebenza.

Ubuso bomgodi wesigamu bunikezwa ungqimba wensimbi, futhi impambana yomgodi wesigamu nomphetho womzimba ngokulandelana unikezwa ngegebe, kanti ubuso begebe yindiza noma ubuso begebe inhlanganisela yendiza kanye nobuso bendawo. Ngokwandisa igebe emikhawulweni yomibili yomgodi wesigamu, amachips ethusi empambanweni yomgodi wesigamu nomngcele womzimba ayasuswa ukwakha i-PCB ebushelelezi, ngokugwema ngempumelelo amachips ethusi asele emgodini wesigamu, aqinisekisa ikhwalithi I-PCB, kanye ne-welding enokwethenjelwa nekhwalithi yokubukeka kwe-PCB enqubeni ye-PCBA, nokuqinisekisa ukusebenza komshini wonke ngemuva komhlangano olandelayo.
