Igishushanyo mbonera cyumuzunguruko
Ikibaho cyumuzunguruko wa SMT nikimwe mubice byingirakamaro mugushushanya hejuru.Ikibaho cyumuzunguruko wa SMT ninkunga yibice byumuzunguruko nibikoresho mubikoresho bya elegitoroniki, bimenya guhuza amashanyarazi hagati yibice byumuzunguruko nibikoresho.Hamwe niterambere ryikoranabuhanga rya elegitoronike, Ingano yimbaho za PCB iragenda iba nto, ubucucike buragenda bwiyongera, kandi ibice byimbaho za PCB bigenda byiyongera.Kubwibyo, PCBs zirasabwa kugira ibisabwa byisumbuyeho kandi byinshi murwego rwimiterere rusange, ubushobozi bwo kurwanya kwivanga, gutunganya no gukora.
Intambwe nyamukuru yo gushushanya PCB;
1: Shushanya igishushanyo mbonera.
2: Kurema isomero ryibigize.
3: Shiraho imiyoboro ihuza imiyoboro hagati yishusho nigishushanyo kiri ku kibaho cyanditse.
4: Gukoresha insinga n'imiterere.
5: Kurema ibicuruzwa byacapwe kandi ukoreshe amakuru nibikorwa byo gushyira no gukoresha amakuru.
Ibibazo bikurikira bigomba gusuzumwa muburyo bwo gushushanya imbaho zumuzingo zacapwe:
Birakenewe kwemeza ko ibishushanyo byibigize mu gishushanyo mbonera cy’umuzunguruko bihuye n’ibintu bifatika kandi ko umuyoboro uhuza ibishushanyo mbonera by’umuzingi ari byo.
Igishushanyo mbonera cyumuzingo cyacapwe ntikireba gusa isano ihuza imiyoboro yishushanyo mbonera, ahubwo inareba bimwe mubisabwa mubuhanga bwumuzunguruko.Ibisabwa mubuhanga bwumuzunguruko ahanini ni ubugari bwumurongo wamashanyarazi, insinga zubutaka nizindi nsinga, guhuza imirongo, hamwe nibintu bimwe na bimwe byihuta cyane biranga ibice, kubuza ibice, kurwanya kwivanga, nibindi.
Ibisabwa kugirango ushyireho icyapa cyumuzunguruko cyacapwe sisitemu yose cyane cyane ureba imyobo yo kwishyiriraho, amacomeka, ibyobo byerekana, ingingo zerekana, nibindi.
Igomba kuba yujuje ibisabwa, gushyira ibice bitandukanye hamwe no kwishyiriraho neza mumwanya wabigenewe, kandi mugihe kimwe, bigomba kuba byoroshye mugushiraho, gukuramo sisitemu, no guhumeka no gukwirakwiza ubushyuhe.
Gukora ibibaho byumuzunguruko byacapwe nibisabwa kugirango bikorwe, kugirango umenyere ibishushanyo mbonera kandi byujuje ibisabwa byumusaruro
Ibikorwa bisabwa, kugirango ibishushanyo mbonera byacapwe byacapwe bishobora gukorwa neza.
Urebye ko ibice byoroshye gushyiramo, gukuramo, no gusana mubikorwa, kandi mugihe kimwe, ibishushanyo biri kumurongo wacapwe, kugurisha, nibindi.
Isahani, vias, nibindi bigomba kuba bisanzwe kugirango barebe ko ibice bitagongana kandi byoroshye gushyirwaho.
Intego yo gushushanya ikibaho cyumuzingo cyacapwe cyane cyane kubisabwa, bityo rero tugomba gusuzuma uburyo bushoboka kandi bwizewe,
Mugihe kimwe, igipande hamwe nubuso bwicapiro ryumuzunguruko byaciwe kugirango bigabanye igiciro.Mu buryo bukwiriye, amakarito manini, binyuze mu mwobo, no mu nsinga bifasha mu kunoza ubwizerwe, kugabanya vias, guhitamo insinga, no kuyikora neza., guhuzagurika nibyiza, kuburyo imiterere rusange yubuyobozi ari nziza.
Ubwa mbere, kugirango akanama gashinzwe kuzenguruka kagere ku ntego ziteganijwe, imiterere rusange yikibaho cyacapwe cyumuzingo hamwe no gushyira ibice bigira uruhare runini, bigira ingaruka kuburyo butaziguye kwishyiriraho, kwizerwa, guhumeka no gukwirakwiza ubushyuhe bwikibaho cyose cyacapwe, no kwifashisha igipimo.
Nyuma yimyanya nimiterere yibigize kuri PCB bimaze kugenwa, tekereza insinga za PCB
Icya kabiri, kugirango ibicuruzwa byateguwe bikore neza kandi neza, PCB igomba gutekereza kubushobozi bwayo bwo kurwanya kwivanga mubishushanyo, kandi ifite umubano wa hafi numuzunguruko wihariye.
Bitatu, nyuma yibigize hamwe nigishushanyo mbonera cyumuzunguruko cyumuzunguruko kirangiye, igishushanyo mbonera cyacyo kigomba gusuzumwa ubutaha, ikigamijwe ni ugukuraho ibintu bibi byose mbere yuko umusaruro utangira, kandi mugihe kimwe, ubwikorezi bwinama yumuzunguruko. bigomba kwitabwaho kugirango habeho ibicuruzwa byiza.n'umusaruro rusange.
Mugihe tuvuga kubyerekeranye no guhuza ibice, tumaze kugira uruhare mubikorwa byubuyobozi bwumuzunguruko.Igishushanyo mbonera cyibibaho byumuzunguruko ni uguteranya muburyo bwimikorere ikibaho cyumuzunguruko hamwe nibice twashizeho binyuze mumurongo wa SMT, kugirango tugere kumashanyarazi meza.Kugirango ugere kumwanya wibicuruzwa byacu byashushanyije.Igishushanyo cya padi, insinga no kurwanya-kwivanga, nibindi, tugomba nanone gusuzuma niba ikibaho twashizeho cyoroshye kubyara umusaruro, niba gishobora guteranyirizwa hamwe nubuhanga bugezweho bwo guterana-tekinoroji ya SMT, kandi mugihe kimwe, bigomba kugerwaho muri umusaruro.Reka ibisabwa kugirango habeho ibicuruzwa bifite inenge bitanga uburebure bwubushakashatsi.By'umwihariko, hari ibintu bikurikira:
1: Imirongo itandukanye ya SMT itanga umusaruro itandukanye, ariko ukurikije ubunini bwa PCB, ubunini bumwe bwa PCB ntabwo buri munsi ya 200 * 150mm.Niba uruhande rurerure ari ruto cyane, urashobora gukoresha gushiramo, kandi ikigereranyo cyuburebure nubugari ni 3: 2 cyangwa 4: 3 Iyo ubunini bwikibaho cyumuzunguruko burenze 200 × 150mm, imbaraga za mashini zubuyobozi bwumuzunguruko zigomba gusuzumwa.
2: Iyo ubunini bwibibaho byumuzunguruko ari bito cyane, biragoye kubikorwa byose bya SMT kumurongo, kandi ntabwo byoroshye kubyara mubice.Ikibaho cyahujwe hamwe kugirango kibe ikibaho cyose gikwiranye n’umusaruro rusange, kandi ubunini bwikibaho cyose bugomba kuba bukwiranye nubunini bwa pasteable.
3: Kugirango uhuze nogushira kumurongo wibyakozwe, intera ya 3-5mm igomba gusigara kumurongo nta kintu na kimwe kirimo, kandi impande ya 3-8mm igomba gusigara kumwanya.Hariho ubwoko butatu bwihuza hagati yimikorere yimikorere na PCB: A idafite impande zuzuzanya, Hano hari itandukanyirizo, B ifite uruhande nigitandukanya, C ifite uruhande kandi ntirutandukanya.Hariho inzira yo gusiba.Ukurikije imiterere yubuyobozi bwa PCB, hariho uburyo butandukanye bwa jigsaw.Kuri PCB Uburyo bwo guhitamo kuruhande rwibikorwa buratandukanye ukurikije moderi zitandukanye.Bamwe bafite ibyobo byerekana kuruhande.Diameter yumwobo ni cm 4-5.Ugereranije, imyanya ihagaze neza iruta iy'uruhande, bityo hariho ibyobo byo guhagarara.Iyo icyitegererezo gitunganya PCB, kigomba kuba gifite imyobo ihagaze, kandi igishushanyo mbonera kigomba kuba gisanzwe, kugirango kidatera ikibazo kubibyazwa umusaruro.
4: Kugirango tumenye neza kandi tugere ku ntera ihanitse yo kwishyiriraho, ni ngombwa gushyiraho ingingo yerekanwe kuri PCB.Niba hari aho byerekanwe kandi niba ari byiza cyangwa atari byiza bizagira ingaruka ku buryo butaziguye ku musaruro rusange w’umurongo wa SMT.Imiterere yikibanza irashobora kuba kare, izengurutse, inyabutatu, nibindi. Kandi diameter iri murwego rwa 1-2mm, kandi igomba kuba iri hagati ya 3-5mm ikikije aho yerekanwe, idafite ibice byose kandi ikayobora .Mugihe kimwe, ingingo yerekanwe igomba kuba yoroshye kandi iringaniye nta Umwanda uhari.Igishushanyo mbonera cyerekana ntigomba kuba hafi yuruhande rwibibaho, kandi hagomba kubaho intera ya 3-5mm.
5: Ukurikije uburyo rusange bwo gukora, imiterere yikibaho nibyiza kuba ifite ikibanza, cyane cyane kugurisha imiraba.Gukoresha urukiramende biroroshye kohereza.Niba hari ikibanza cyabuze ku kibaho cya PCB, ikibanza cyabuze kigomba kuzuzwa muburyo bwimikorere.Kuri imwe Ikibaho cya SMT cyemerera kubura ahantu.Ariko ibibanza byabuze ntibyoroshye kuba binini cyane kandi bigomba kuba munsi ya 1/3 cyuburebure bwuruhande.
Muri make, kuba ibicuruzwa bifite inenge birashoboka muri buri murongo, ariko kubijyanye nigishushanyo mbonera cyubuyobozi bwa PCB, bigomba gutekerezwa mubice bitandukanye, kugirango bidashobora gusa kumenya intego yo gushushanya ibicuruzwa, ariko bikwiriye kandi kumurongo wa SMT mubikorwa.Umusaruro mwinshi, gerageza uko dushoboye kugirango dushushanye ikibaho cyiza cya PCB, kandi ugabanye amahirwe yibicuruzwa bifite inenge.
