Impamvu nigisubizo cyumutuku wa PCB umuzunguruko wibicuruzwa bigurisha mask ya ecran

Inganda zumuzunguruko wa PCB zamye zifite ibisabwa byujuje ubuziranenge kubikorwa byo gukora.Muri byo, umutuku wibibaho byumuzunguruko wa PCB uterwa no kugurisha mask ya ecran ya ecran ni ibintu bisanzwe bitifuzwa.Ntabwo bigira ingaruka gusa kubwiza bwo hanze bwa PCB, ahubwo bigira ingaruka kubibaho.Hariho n'ingaruka nziza mubikorwa.Iyi ngingo - umuyoboro wibikoresho bya pcb bizakuyobora kugirango usobanukirwe byimbitse kubitera nigisubizo cyumutuku wubuyobozi bwa PCB uterwa no kugurisha mask ya ecran ya ecran ku kibaho cyumuzunguruko wa PCB.

1. Impamvu ituma PCB yumuzunguruko ugurisha mask ya ecran ya ecran itera umutuku hejuru yubuyobozi

1. Umubyimba wububiko bwa mask yagurishijwe ntabwo ugera kurwego rusanzwe cyangwa hariho ibisigazwa bisigaye:

Igicuruzwa cya mask gicuruza bivuga urwego rwokwirinda rutwikiriye ikibaho cyumuzunguruko nyuma yo gucapisha hamwe na wike ya masike ya mask kugirango wirinde ko umuziki utagira ingaruka nkibidukikije hanze;mugihe umubyimba wububiko bwa mask yagurishijwe utageze kurwego rusanzwe cyangwa hari ibisebe bisigaye, birakenewe Kuri Muri iki cyiciro, reaction ya okiside ikunda kubaho mugihe ihuye nubushyuhe bwo hejuru, bikavamo umutuku hejuru yubuyobozi, bikaviramo ubukene Ubwiza bwa PCB.

1. Ubwiza bwa wino ntabwo bugera kubisanzwe:

Niba wino ubwayo ikoreshwa mugucapura mask ya ecran ya ecran ifite ibibazo bifite ireme, nka wino yarangiye hamwe no kwiyongera kwino ya wino, birashobora gutuma ingaruka zo gukingira igipapuro cyabigenewe cyananirana, cyangwa ntigishobora gupfuka umuzenguruko, hasigara icyuho nibindi icyuho cyiza, amaherezo kiganisha ku bintu bitifuzwa nko gutukura hejuru yubuyobozi bishobora gutera ingaruka zitamenyekana ningaruka kumikorere nubuziranenge.

 3. Flux na bagurisha mask wino ntabwo ihuye:

 Ubuziranenge bubi bwa PCB yacapishijwe imbaho ​​zumuzingi akenshi bibaho muguhuza ibikorwa bifitanye isano cyangwa byegeranye.Kurugero, flux hamwe nugurisha birwanya wino ntibihuye cyangwa ntibishobora kubangikana, bishobora no gukurura amakimbirane, guhindura imitungo, nibindi, bikavamo umutuku hejuru yubuyobozi.

2. Gukemura ingamba kububiko bwumuzunguruko wa PCB kugurisha mask ya ecran ya ecran itera umutuku hejuru yubuyobozi

 1.PCB yumuzunguruko wumudugudu ugurisha mask ya ecran icapa-mbere yumusaruro ugaragara neza:

 Guhitamo mask ya wino ya solder, moda ya viscosity modulation, wino nziza yubuzima bwiza, flux nibindi bikoresho bifitanye isano nogukoresha bisanzwe hamwe nubuziranenge bwimikorere, gukora ibipimo nintambwe zo kwirinda ingaruka ziterwa na PCB ziterwa nibikoresho fatizo.

 2.PCB yumuzunguruko wumudugudu ugurisha mask ya ecran icapura-mubikorwa byo gukora neza:

 Imashini icapura ya PCB yumuzunguruko ya PCB idahwema kuvuga muri make no gukemura no gukora ibipimo ngenderwaho bisanzwe bishingiye ku icapiro bikenera kwemeza ibipimo bya siyansi kandi bishyize mu gaciro, bityo bigatuma umusaruro uhoraho kandi uhamye.

 3.PCB yumuzunguruko wumudugudu wagurishije mask ya ecran icapa-nyuma yumusaruro mwiza wo kugenzura neza:

 Gutegura ingamba zifatika zo kugenzura ubuziranenge kugirango hamenyekane ibibazo mugihe kugirango wirinde kwaguka kwigihombo no kugabanya ingaruka kumikorere.

 4.PCB yumuzunguruko wumudugudu ugurisha mask yerekana icapiro-amahugurwa yumusaruro wabakozi:

 Kongera ubushobozi bwabakozi kumenya, gusuzuma, gusesengura no gukemura ibibazo byubuziranenge bwibikorwa, kuzamura ubumenyi bwumwuga no gusobanukirwa n’amahame y’ibibazo bibi, gukora isuzuma n’amahugurwa buri gihe, no gushyiraho uburyo busanzwe bwo gukora kugirango abakozi bashobore gukora neza kandi neza, kandi basubize Kuri no gukemura ibibazo bitandukanye mugihe gikwiye.ibintu byihutirwa.

3. PCB yumuzunguruko wa PCB kugurisha ecran ya ecran itera ubuso bwibibaho guhinduka umutuku.Icyo gukora muri make

 Ikibazo cyumuzunguruko wa PCB ugurisha mask yerekana icapiro ryumutuku nikibazo gikunze kugaragara mubikorwa, ariko ntabwo arikibazo kitoroshye.Akenshi ni nto gusa kandi mubyiciro byambere, kandi biroroshye kugaragara muruganda rudasanzwe kandi rusanzwe.Kugira ngo iki kibazo gikemuke, hagomba gushyirwaho uburyo bwo gukora bwumwuga kandi busanzwe, guhitamo PCB yumuzunguruko ukwiye kugurisha imashini yerekana imashini icapura imashini hamwe nabakora umwuga kugirango birinde ko habaho amakosa nkaya yo murwego rwo hasi, bizagira ingaruka kumiterere yikigo kandi byuzuye inyungu.
