Niki Nakagombye kwitondera mugihe cyoza ikibaho cya PCBA

MuriSMTUbuso bwo guteranya hejuru, ibintu bisigaye byakozwe mugihe cyaInteko ya PCBkugurisha biterwa na flux na salete paste, birimo ibice bitandukanye: ibikoresho kama na ion ibora.Ibikoresho kama birashobora kwangirika cyane, kandi ion zisigaye kumpapuro zagurishijwe zirashobora gutera amakosa yigihe gito.Byongeyeho, ibintu byinshi bisigaye kuriPCBAikibaho kiranduye kandi ntabwo cyujuje ibyangombwa bisuku byumukoresha wa nyuma.Kubwibyo, byanze bikunze gusukuraPCBAikibaho.Ariko,Ikibaho cya PCBAntigomba guhanagurwa bisanzwe, kandi ibisabwa bikomeye nibisabwa bigomba gukurikizwa mugihe ukoresheje aPCBAimashini isukura.

Hano haribisobanuro birambuye kubibazo bimwe bisanzwe mugihe cyaUbuyobozi bwa PCBAinzira yo gukora isuku:

Icyambere, nyuma yinteko no kugurisha kwaicyapa cyumuzunguruko ibice, isuku bigomba gukorwa vuba bishoboka kugirango ikureho burundu ibisigisigi bisigaye, uwagurishije, nibindi byanduza mubibaho byacapwe (kubera ko ibisigara bisigaye bizagenda bikomera buhoro buhoro mugihe, bigakora ibintu byangirika nkumunyu wa halide).Ku rundi ruhande, mu gihe cyo gukora isuku, ni ngombwa kwirinda ibintu byangiza isuku byinjira mu bikoresho bya elegitoronike bidafunze burundu kugira ngo birinde kwangirika cyangwa kwangirika kw’ibigize.

Nyuma yo koza ibice byumuzunguruko byacapwe, bigomba gushyirwa mu ziko kuri 40 ~ 50 ° C hanyuma bigatekwa muminota 20 ~ 30, kandi ibice ntibigomba gukorwaho amaboko yambaye ubusa mbere yuko byuma rwose.Byongeye, inzira yisuku ntigomba kugira ingaruka kuriibikoresho bya elegitoroniki, ibimenyetso, kugurisha hamwe, hamwe nu kibaho cyacapwe
