Intangiriro kubikorwa bya SMT

Intangiriro ya SMD

SMT patch bivuga mu magambo ahinnye y'uruhererekane rw'ibikorwa bitunganijwe hashingiwe kuri PCB.PCB (Icapiro ryumuzunguruko) ni ikibaho cyumuzingo cyacapwe.

SMT ni Ikoranabuhanga rya Surface Mount Technology (Surface Mount Technology) (mu magambo ahinnye ya Surface Mounted Technology), nubuhanga bukoreshwa cyane mubikorwa byo guteranya ibikoresho bya elegitoroniki.
Ikoranabuhanga rya elegitoroniki yo guteranya tekinoroji (Surface Mount Technology, SMT), izwi nka tekinoroji yo hejuru cyangwa tekinoroji yo hejuru.Nubwoko butari pin cyangwa bugufi-buyobora hejuru yubuso (SMC / SMD kubugufi, Igishinwa bita chip ibice) byashyizwe hejuru yikibaho cyacapwe cyacapwe (Icapa ryumuzunguruko, PCB) cyangwa hejuru yizindi ntera, binyuze mu guteranya umuzenguruko no guhuza ikoranabuhanga rigurishwa kandi riteranijwe hamwe nuburyo bwo kugurisha ibicuruzwa cyangwa kugurisha ibicuruzwa.

Mubihe bisanzwe, ibicuruzwa bya elegitoronike dukoresha byateguwe na PCB hiyongereyeho ubushobozi butandukanye, résistoriste nibindi bikoresho bya elegitoronike ukurikije igishushanyo mbonera cyateganijwe, bityo ibikoresho byose byamashanyarazi bikenera tekinoroji zitandukanye zo gutunganya chip ya SMT kugirango itunganyirizwe, Igikorwa cyayo ni kumeneka kugurisha ibicuruzwa cyangwa kashe ya kashe kuri padi ya PCB kugirango witegure kugurisha ibice.Ibikoresho byakoreshejwe ni imashini icapa ecran (imashini icapa ecran), iherereye ku isonga ryumurongo wa SMT.

Inzira y'ibanze ya SMT

1. Gucapa (icapiro ry'ubudodo): Igikorwa cyayo ni ugucapa paste yagurishijwe cyangwa ibishishwa bifata kumpapuro za PCB kugirango witegure kugurisha ibice.Ibikoresho byakoreshejwe ni imashini icapa ecran (imashini icapura ecran), iherereye ku isonga ryumurongo wa SMT.

2. Gutanga kole: Ni ukumanura kole kumwanya uhamye wubuyobozi bwa PCB, kandi umurimo wingenzi wacyo ni ugukosora ibice kubuyobozi bwa PCB.Ibikoresho byakoreshejwe ni imashini itanga kole, iherereye imbere yumurongo wa SMT cyangwa inyuma yibikoresho byo gupima.

3. Gushiraho: Igikorwa cyayo nugushiraho neza ibice byubuso bwubuso kumwanya uhamye wa PCB.Ibikoresho byakoreshejwe ni imashini ishyira, iri inyuma yimashini icapa ecran kumurongo wa SMT.

4. Gukiza: Igikorwa cyayo ni ugushonga ibishishwa, kugirango ibice byubuso bwubuso hamwe nubuyobozi bwa PCB bihujwe hamwe.Ibikoresho byakoreshejwe ni ifuru ikiza, iherereye inyuma yimashini ishyira kumurongo wa SMT.

5. Kugarura kugurisha: Igikorwa cyayo ni ugushonga paste yagurishijwe, kugirango ibice byubuso bwubuso hamwe nubuyobozi bwa PCB bihujwe hamwe.Ibikoresho byakoreshejwe ni ifuru yerekana / kugurisha, iri inyuma yimashini ishyira kumurongo wa SMT.

6. Isuku: Igikorwa cyayo ni ugukuraho ibisigazwa byo gusudira byangiza umubiri wumuntu nka flux ku kibaho cya PCB.Ibikoresho byakoreshejwe ni imashini imesa, kandi ikibanza ntigishobora gukosorwa, kumurongo cyangwa kumurongo.

7. Ubugenzuzi: Igikorwa cyayo ni ukugenzura ubuziranenge bwo gusudira hamwe nubwiza bwinteko yubuyobozi bwa PCB bwateranijwe.Ibikoresho byakoreshejwe birimo gukuza ibirahuri, microscope, ibizamini byo kumurongo (ICT), igeragezwa ryikigereranyo, kugenzura ibyuma byikora (AOI), sisitemu yo kugenzura X-RAY, ibizamini bikora, nibindi. Ikibanza gishobora gushyirwaho ahantu heza kumurongo wibikorwa ukurikije ibikenewe byo gutahura.

Inzira ya SMT irashobora kunoza cyane imikorere yumusaruro nukuri kubibaho byacapishijwe imizunguruko, kandi ikamenya mubyukuri ibyakozwe na PCBA.

Guhitamo ibikoresho bibyara umusaruro urashobora kubona inshuro ebyiri ibisubizo hamwe nigice cyimbaraga.Inganda zikoresha inganda za Chengyuan zitanga ubufasha bumwe na serivisi kuri SMT na PCBA, kandi igategura gahunda yumusaruro ukwiye kuri wewe.
