1. Kuki BGA iherereye mu mwobo ugurisha?Ni ubuhe buryo bwo kwakira abantu?
Re: Mbere ya byose, uwagurishije mask yamashanyarazi ni ukurinda ubuzima bwa serivisi binyuze, kuko umwobo usabwa kumwanya wa BGA muri rusange ni muto, hagati ya 0.2 na 0.35mm.Sirup imwe ntabwo yoroshye kuyumisha cyangwa guhumeka, kandi biroroshye gusiga ibisigazwa.Niba mask yo kugurisha idacomeka umwobo cyangwa icyuma nticyuzuye, hazaba hasigaye ibintu by’amahanga bisigaye cyangwa amasaro y'amabati mugutunganya nyuma nko gutera amabati na zahabu yo kwibiza.Umukiriya akimara gushyushya ibice mugihe cyo kugurisha ubushyuhe bwinshi, ibintu byamahanga cyangwa amasaro yamabati mumwobo bizasohoka kandi bigumane nibigize, bitera inenge mumikorere yibigize, nkumuzunguruko ufunguye kandi mugufi.BGA iherereye mu mwobo ugurisha mask A, igomba kuba yuzuye B, nta gutukura cyangwa kwerekana umuringa wibinyoma byemewe, C, ntago byuzuye, kandi gusohoka birenze padi kugurishwa kuruhande rwayo (bizagira ingaruka kuri Ingaruka yo gushiraho Ingaruka). 
2. Ni irihe tandukaniro riri hagati yikirahure cyo hejuru cyameza yimashini igaragaramo nikirahure gisanzwe?Ni ukubera iki ibyerekana itara ryerekanwa ridahwanye? Re: Ikirahuri cyameza yimashini imurika ntishobora kubyara urumuri iyo urumuri runyuze.Niba urumuri rw'itara rimurika ruringaniye kandi rworoshye, noneho iyo urumuri rumuritseho, ukurikije ihame ryumucyo, rukora urumuri rumwe rwonyine rumurika kumubaho kugirango rugaragare.Niba urwobo rufunitse kandi rutaringaniye ukurikije urumuri Ihame ni uko urumuri rumurikira ku karubanda n'umucyo umurikira kuri ruhurura bizakora imirasire itabarika y'urumuri rutatanye, rukora urumuri rudasanzwe ariko rumwe ku kibaho kugira ngo rugaragare, bitezimbere Ingaruka zo Kugaragara. 
3. Iterambere ryuruhande ni iki?Ni izihe ngaruka nziza ziterwa niterambere ryuruhande? Re: Agace k'ubugari hepfo yigice aho amavuta yicyatsi kuruhande rumwe rwamadirishya yagurishijwe yatunganijwe byitwa iterambere ryuruhande.Iyo iterambere ryuruhande ari rinini cyane, bivuze ko ubuso bwamavuta yicyatsi cyigice cyateye imbere kandi kikaba gihura nuruhu rwa substrate cyangwa umuringa ni kinini, kandi urugero rwa dangling rwakozwe na rwo ni runini.Gutunganya nyuma nko gutera amabati, kurohama amabati, Zahabu ya Immersion hamwe nibindi bice bikura bitera kwibasirwa nubushyuhe bwinshi, umuvuduko hamwe n amavuta amwe yibasira amavuta yicyatsi.Amavuta azagabanuka.Niba hari ikiraro cyamavuta yicyatsi kumwanya wa IC, bizaterwa mugihe umukiriya ashyizeho ibice byo gusudira.Bizatera ikiraro kigufi.
4. Ni ubuhe buryo bubi bwo kugurisha ibicuruzwa?Ni izihe ngaruka nziza zizatera? Re: Nyuma yo gutunganyirizwa hamwe na mask yo kugurisha, ihura nudupapuro twibigize cyangwa ahantu hagomba kugurishwa mugihe cyanyuma.Mugihe cyo kugurisha mask yo guhuza / kwerekana, biterwa na bariyeri yumucyo cyangwa imbaraga zo guhura nibibazo.Hanze cyangwa amavuta yicyatsi yose atwikiriwe niki gice ahura numucyo kugirango atere guhuza ibikorwa.Mugihe cyiterambere, amavuta yicyatsi muriki gice ntazashonga nigisubizo, kandi hanze cyangwa padi yose igomba kugurishwa ntishobora kugaragara.Ibi byitwa kugurisha.Kugaragara nabi.Guhura nabi bizavamo kunanirwa gushiraho ibice mubikorwa bikurikiraho, kugurisha nabi, kandi, mubihe bikomeye, uruziga rufunguye. 5. Ni ukubera iki dukeneye kubanza gutunganya isahani yo gusya hamwe na mask yo kugurisha? Re: 1. Ubuso bwumuzunguruko wumuzunguruko burimo ikibaho cyanditseho fayili hamwe na substrate hamwe n'umuringa wabanjirijwe mbere nyuma yo gutobora umwobo.Kugirango hamenyekane neza ko hagati ya firime yumye hamwe nubutaka bwa substrate, hejuru yubutaka harasabwa kuba hatarimo ibice bya oxyde, irangi ryamavuta, ibikumwe byintoki nundi mwanda, nta buriri bwo gucukura, kandi nta isahani ikaze.Kugirango wongere aho uhurira hagati ya firime yumye nubuso bwa substrate, substrate nayo isabwa kugira ubuso buto.Kugirango wuzuze ibisabwa bibiri byavuzwe haruguru, substrate igomba gutunganywa neza mbere yo gufata amashusho.Uburyo bwo kuvura bushobora kuvugwa muri make nko gusukura imashini no gusukura imiti.
2. Ihame rimwe nukuri kuri mask imwe yo kugurisha.Gusya ku kibaho mbere ya mask yo kugurisha ni ugukuraho ibice bimwe bya oxyde, irangi ryamavuta, igikumwe nundi mwanda hejuru yubuyobozi, kugirango hongerwe aho uhurira hagati ya wino ya mask yagurishijwe nubuso bwibibaho hanyuma bikomere.Ubuso bwibibaho nabwo burasabwa kugira ubuso buto (kimwe nipine yo gusana imodoka, ipine igomba kuba hasi kugeza ahantu habi kugirango ihuze neza na kole).Niba udakoresha gusya mbere yumuzunguruko cyangwa masike yo kugurisha, hejuru yikibaho ugomba gushiramo cyangwa gucapwa bifite ibice bimwe bya oxyde, irangi ryamavuta, nibindi, bizahita bitandukanya mask yagurishijwe hamwe na firime yumuzunguruko na forme yububiko. kwigunga, na firime aha hantu izagwa hanyuma ikuremo mugihe gikurikira. 6. Ubukonje ni iki?Ni izihe ngaruka ubwiza bwibicuruzwa byabigenewe bigira ingaruka kubikorwa bya PCB? Re: Viscosity ni igipimo cyo gukumira cyangwa kurwanya imigezi.Ubukonje bwa mask wugurisha wino bugira uruhare runini mubikorwa bya PCB .Iyo ububobere buri hejuru cyane, biroroshye gutera amavuta cyangwa gukomera kuri net.Iyo ibishishwa biri hasi cyane, amazi ya wino ku kibaho aziyongera, kandi biroroshye gutera amavuta kwinjira mu mwobo.N'igitabo cyo munsi ya peteroli.Ugereranije, iyo umuringa wo hanze uba mwinshi (≥1.5Z0), ubwiza bwa wino bugomba kugenzurwa kugirango bugabanuke.Niba ububobere buri hejuru cyane, amazi ya wino azagabanuka.Muri iki gihe, hepfo nu mfuruka zumuzingi Ntabwo bizaba amavuta cyangwa ngo agaragare. 7. Ni irihe sano n'itandukaniro riri hagati yiterambere ribi no kugaragara nabi? Re: Ingingo zimwe: a.Hano hari amavuta ya mask yo kugurisha hejuru aho umuringa / zahabu bigomba kugurishwa nyuma ya mask yo kugurisha.Impamvu ya b ni imwe.Igihe, ubushyuhe, igihe cyo kwerekana imbaraga nimbaraga zurupapuro rwo guteka birasa. Itandukaniro: Agace kagizwe no kugaragara nabi ni nini, kandi masike yo kugurisha isigaye iva hanze kugeza imbere, kandi ubugari na Baidu birasa.Byinshi muribi bigaragara kuri padi idafite poro.Impamvu nyamukuru nuko wino muriki gice ihura nurumuri ultraviolet.Umucyo urabagirana.Amavuta yo kugurisha asigaye avuye mumajyambere mabi aroroshye gusa munsi yurwego.Ubuso bwacyo ntabwo ari bunini, ariko bugizwe na firime yoroheje.Iki gice cya wino giterwa ahanini nibintu bitandukanye byo gukiza kandi bigizwe kuva wino yo hejuru.Imiterere ikurikiranye, igaragara muri padi.
8. Kuki mask yo kugurisha itanga ibibyimba?Nigute twakwirinda? Re: (1) Amavuta ya mask ya Solder muri rusange avangwa kandi agizwe numukozi mukuru wa wino + umuti ukiza + diluent.Mugihe cyo kuvanga no gukurura wino, umwuka runaka uzaguma mumazi.Iyo wino inyuze muri scraper, insinga Nyuma yuko inshundura zinjijwe hagati yazo hanyuma zigatembera ku kibaho, iyo zihuye n’umucyo ukomeye cyangwa ubushyuhe bungana mu gihe gito, gaze muri wino izatemba byihuse hamwe no kwihuta kwa mugenzi we wino, kandi izahinduka cyane.
. gaze irashyuha kwaguka no gutera ibibyimba mugihe cyo gukiza no guhura.
(3) Umurongo umwe uterwa ahanini numurongo muremure.Iyo igikonjo gihuye numurongo, inguni yigituba n'umurongo byiyongera, kuburyo wino ya masike yagurishijwe idashobora gucapishwa munsi yumurongo, kandi hariho gaze hagati yumurongo wumurongo na mask yuwagurishije. wino, Ubwoko buto buto buzashirwaho iyo bushyushye.
Kwirinda:
a.Irangi ryakozwe rihagaze mugihe runaka mbere yo gucapa,
b.Ikibaho cyacapwe nacyo gihamye mugihe runaka kugirango gaze iri muri wino hejuru yikibaho izagenda ihindagurika buhoro buhoro hamwe na wino, hanyuma uyikure mugihe runaka.Guteka ku bushyuhe.
