Ubucucike bw'iteraniro ni bwinshi, ibicuruzwa bya elegitoronike ni bito mu bunini no mu mucyo mu buremere, kandi ingano n'ibigize ibice bigize ibice ni hafi 1/10 cy'ibikoresho bisanzwe byacometse.
Nyuma yo gutoranya muri rusange SMT, ingano yibicuruzwa bya elegitoronike yagabanutseho 40% kugeza kuri 60%, naho uburemere bugabanukaho 60% kugeza 80%.
Kwizerwa cyane hamwe no kurwanya kunyeganyega gukomeye.Igipimo gike cyo kugurisha hamwe.
Ibintu byiza biranga inshuro nyinshi.Kugabanya electromagnetic na RF kwivanga.
Biroroshye kugera kuri automatike, kunoza imikorere.Mugabanye igiciro 30% ~ 50%.Bika amakuru, ingufu, ibikoresho, abakozi, igihe, nibindi
Kuki ukoresha Ubuhanga bwa Surface (SMT)?
Ibicuruzwa bya elegitoronike bishakisha miniaturizasiya, kandi ibice byacometse mu bikoresho byakoreshejwe ntibishobora kugabanuka.
Imikorere yibicuruzwa bya elegitoronike iruzuye, kandi uruziga rwinjizwamo (IC) rwatoranijwe ntirufite ibice bisobekeranye, cyane cyane binini, binini cyane, hamwe nibice byo hejuru bigomba guhitamo;
Ubwinshi bwibicuruzwa, gutangiza ibicuruzwa, uruganda kugeza ku giciro gito cyane, rutanga ibicuruzwa byiza kugirango uhuze ibyo umukiriya akeneye kandi ashimangire guhangana ku isoko
Iterambere ryibikoresho bya elegitoronike, iterambere ryumuzunguruko (ics), gukoresha inshuro nyinshi amakuru ya semiconductor
Impinduramatwara ya tekinoroji ya elegitoronike ni ngombwa, yiruka ku isi
Kuberiki ukoresha inzira idafite isuku mubuhanga bwo gushiraho hejuru?
Mubikorwa byo kubyaza umusaruro, amazi yimyanda nyuma yo koza ibicuruzwa azana umwanda wamazi meza, isi ninyamaswa nibimera.
Usibye gusukura amazi, koresha ibishishwa kama birimo chlorofluorocarbone (CFC & HCFC) Isuku nayo itera umwanda no kwangiza ikirere nikirere.Ibisigisigi byogusukura bizatera ruswa kubibaho byimashini kandi bigira ingaruka zikomeye kumiterere yibicuruzwa.
Mugabanye ibikorwa byogusukura nigiciro cyo gufata imashini.
Nta suku rishobora kugabanya ibyangijwe na PCBA mugihe cyo kugenda no gukora isuku.Haracyariho ibice bimwe bidashobora gusukurwa.
Ibisigisigi bya flux biragenzurwa kandi birashobora gukoreshwa hubahirijwe ibisabwa kugirango ibicuruzwa bigenzurwe neza.
Ibisigisigi bisigaye byatejwe imbere kubikorwa byamashanyarazi kugirango birinde ibicuruzwa byarangiye kumeneka amashanyarazi, bikaviramo gukomeretsa.
Nubuhe buryo bwa SMT bwo gutahura uruganda rutunganya ibiti bya SMT?
Kumenyekanisha mugutunganya SMT nuburyo bwingenzi cyane kugirango hamenyekane ubuziranenge bwa PCBA, uburyo nyamukuru bwo gutahura burimo intoki zerekana intoki, kugurisha paste umubyimba wa gauge yerekana, guhitamo optique, gutahura X-ray, gupima kumurongo, gupima urushinge, nibindi, nibindi, bitewe nibintu bitandukanye byo gutahura nibiranga buri gikorwa, uburyo bwo gutahura bukoreshwa muri buri nzira nabwo buratandukanye.Muburyo bwo gutahura uruganda rutunganya smt patch, intoki zerekana amashusho hamwe na automaticOptical igenzura hamwe na X-ray nuburyo butatu bukoreshwa cyane mugusuzuma inteko.Kwipimisha kumurongo birashobora kuba ibizamini bihamye no kugerageza imbaraga.
Global Wei Technology iguha intangiriro yuburyo bumwe bwo kumenya:
Ubwa mbere, uburyo bwo kubona intoki.
Ubu buryo bufite ibitekerezo bike kandi ntibukeneye guteza imbere gahunda yikizamini, ariko buratinda kandi bufite intego kandi bugomba kugenzura neza ahantu hapimwe.Bitewe no kubura ubugenzuzi bugaragara, ntibikunze gukoreshwa nkibanze nyamukuru byo kugenzura ubuziranenge bwo gusudira bisobanura kumurongo uriho wo gutunganya SMT, kandi ibyinshi muribi bikoreshwa mugukora nibindi.
Icya kabiri, uburyo bwo kumenya neza.
Hamwe no kugabanya ingano yububiko bwa PCBA chip hamwe no kwiyongera kwububiko bwumuzunguruko wumuzunguruko, igenzura rya SMA riragenda rirushaho kuba ingorabahizi, kugenzura amaso yintoki nta mbaraga bifite, guhagarara kwayo no kwizerwa biragoye guhaza ibikenewe byumusaruro no kugenzura ubuziranenge, bityo imikoreshereze ya dinamike igenda iba myinshi kandi ikomeye.
Koresha igenzura ryikora (AO1) nkigikoresho cyo kugabanya inenge.
Irashobora gukoreshwa mugushakisha no gukuraho amakosa hakiri kare mugutunganya ibice kugirango igere kubikorwa byiza.AOI ikoresha sisitemu yo kureba iyambere, uburyo bushya bwo kugaburira urumuri, gukuza cyane hamwe nuburyo bukomeye bwo gutunganya kugirango ugere ku gipimo cyo gufata inenge ku muvuduko mwinshi.
Umwanya wa AOl kumurongo wa SMT.Mubusanzwe hariho ubwoko 3 bwibikoresho bya AOI kumurongo wibyakozwe na SMT, icya mbere ni AOI gishyirwa kumacapiro ya ecran kugirango hamenyekane amakosa ya paste paste, ibyo bita post-ecran ya AOl.
Iya kabiri ni AOI ishyirwa nyuma yama patch kugirango imenye ibikoresho byubaka amakosa, bita post-patch AOl.
Ubwoko bwa gatatu bwa AOI bushyirwa nyuma yo kugaruka kugirango hamenyekane ibikoresho byashizwe hamwe no gusudira icyarimwe, byitwa post-reflow AOI.
