Mu ikoranabuhanga rya elegitoroniki zigezweho, rikoreshwa ryakoreshejwe cyane mu bimenyetso bya digitale, imitako y'imbere no mu mirima iterwa n'umucyo mwinshi, ubusobanuro bukomeye, kirekire ndetse n'izindi nyungu n'izindi nyungu. Muburyo bwo gukora bwo gukora bwayobowe, tekinoroji ya engcaplatilation ni ihuriro ryingenzi. Muri bo, tekinoroji ya SMD Ikoranabuhanga hamwe n'ikoranabuhanga rya cob ni ingero ebyiri zingenzi. None, ni irihe tandukaniro riri hagati yabo? Iyi ngingo izaguha isesengura ryimbitse.
1.Ni iki cyo gupakira ikoranabuhanga SMD, Ihame rya SMD
Ibikoresho bya SMD, izina ryuzuye ryibikoresho byashizweho (igikoresho cyashizweho hejuru), ni ubwoko bwibigize hakoreshejwe ibikoresho bya elegitoroniki byiciro byinama yacapishijwe (PCB). Ikoranabuhanga rinyuze mu mashini ishyirwa mu bikorwa, Chip yayoboye (ubusanzwe ikubiyemo ibintu bisohora byoroheje n'ibikoresho bikenewe kandi binyuze mu bundi buryo bwo guhaguruka no ku bundi buryo bwo kuvugurura amashanyarazi .SMD Ikoranabuhanga rituma ibice bya elegitoronike bitoroshye, byororoka muburemere, kandi bifasha igishushanyo mbonera cyibicuruzwa byoroshye kandi byoroheje.
2.Ibyiza nibibi byikoranabuhanga ba SMD
2.1 Ibyiza byo gupakira ikoranabuhanga
(1)Ingano nto, uburemere bworoshye:Ibikoresho byo gupakira smd ni bito, byoroshye guhuza ubucucike bwisumbuye, bifasha igishushanyo mbonera cyibicuruzwa bya elegitoronike nacyo.
(2)Ibyiza-byinshi biranga:Amapine ngufi hamwe ninzira zigufi zifasha kugabanya inducance no kurwanya, guteza imbere imikorere ya metero nyinshi.
(3)Byoroshye kumusaruro wikora:bikwiranye no gukora imashini yikora, kunoza imikorere myiza no gutuza ubuziranenge.
(4)Imikorere myiza yubushyuhe:Guhuza neza na PCB hejuru, bifasha gutandukana nubushyuhe.
2.2 Ingaruka zo gupakira Inteko
(1)Kubungabunga ugereranije: Nubwo uburyo bwo kwiyongera bworoshye bworoshye gusana no gusimbuza ibice, ariko kubijyanye no kwishyira hamwe cyane, gusimbuza ibice byihariye birashobora kuba bitoroshye.
(2)Agace kagabanijwe ubushyuhe buke:Ahanini binyuze kuri padi na gel ahinnye yubushyuhe, igihe kinini akazi gakomeye gashobora gukurura ubushyuhe, bigira ingaruka mubuzima bwa serivisi.
3.Ikoranabuhanga rya cob ripakirana, Ihame rya cob
Cob Package, izwi ku izina rya Chip ku kibaho (Chip kuri Package y'Ubuyobozi), ni chip yambaye ubusa yasukuwe mu buhanga bwa PCB. Inzira yihariye ni chip yambaye ubusa (chip umubiri na i / o kurira muri kristu yo hejuru) hamwe nubwiza bwinjijwe muri PCB, hanyuma ukanyura muri wire, hanyuma ukanyura muri wire, hanyuma unyuze muri PCB, hanyuma unyuze muri PCB, hanyuma ukanyura muri wire, hanyuma ukanyura muri wire (nka alumini cyangwa wa zahabu) muri iki gikorwa yo mu gitutu cy'ubushyuhe, chip i / o terminal na pcb padi zihujwe, hanyuma zifunze hamwe no kurinda ibihangano. Iri tandukaniro rikuraho itara gakondo ya LED isaro excaplatilation, bigatuma paki yoroshye.
4.Ibyiza nibibi byikoranabuhanga rya cob
4.1 cob gupakira ikoranabuhanga
(1) pake ikwiye, ingano ntoya:Kurandura amakaramu yo hepfo, kugirango ugere ku bunini buto.
(2) Imikorere isumba byose:Inkonzi ya zahabu ihuza chip na chip on orchine, intera yo kwandura ibimenyetso ni ngufi, ikagabanya uburoko no guterura nibindi bibazo byonoza imikorere.
(3) Gutandukana neza:Chip isudikurwa muri PCB, kandi ubushyuhe bwashutswe binyuze mu kibaho cyose cya PC, kandi ubushyuhe burashukwa byoroshye.
(4) Imikorere ikomeye yo kurinda:Igishushanyo mbonera cyuzuye, gifite amazi, ubuhehere, gihamya, gihamya yumukungugu, anti-static nibindi bikorwa birinda.
(5) Uburambe bwiza bugaragara:Nkiso Inkomoko yubuso, imikorere yibara irasobanutse neza kandi nziza cyane itunganijwe, ibereye kureba hafi.
4.2 IKIBAZO CY'IKORANABUHANGA ZA COB
(1) Ingorane zo kubungabunga:Chip na PCB gusudira, ntibishobora guseswa bitandukanye cyangwa gusimbuza chip, ibiciro byo kubungabunga ni byinshi.
(2) Ibisabwa bifatika:Inzira yo gupakira ibisabwa ibidukikije ni muremure cyane, ntabwo yemerera umukungugu, amashanyarazi ahamye hamwe nubundi buryo bwo kwanduza.
5. Itandukaniro riri hagati yikoranabuhanga rya SMD disiki hamwe nikoranabuhanga rya cob
Ikoranabuhanga rya SMD Ikoranabuhanga hamwe na Cob Ikoranabuhanga mu murima Edred Explow Explow Explow Express yakozweho ibintu byihariye, itandukaniro riri hagati yabo rigaragarira cyane cyane mu mahame, uburemere n'uburemere, uburemere bwo kubungabunga no gushyira mu bikorwa no gusaba. Ibikurikira ni ikigereranyo kirambuye no gusesengura:
5.1 Uburyo bwo gupakira
Ikoranabuhanga rya Parabule ryateganijwe: Izina ryuzuye ni ahantu hashyizwe hejuru, nikihe buryo bwo gupakira abagurisha chip yakuweho ku buso bwanditse (PCB) binyuze mumashini ya parike. Ubu buryo busaba Chip ya LED ipakira mbere kugirango ikore ibice byigenga hanyuma bigashyirwa kuri PCB.
Ikoranabumba rya Gupakira rya ⑵COB: Izina ryuzuye ni chip ku kibaho, nikihe buryo bwo gupakira abagurisha mu buryo butaziguye chip yambaye ubusa kuri PCB. Ikuraho Intambwe zipakijwe zisambo gakondo ziyobowe, zihuza Chip yambaye ubusa kuri PCB hamwe na kole itwara neza cyangwa yubushyuhe, hanyuma umenye amashanyarazi binyuze mumugozi wicyuma.
5.2 Ingano nuburemere
Gupakira: Nubwo ibice ari bito mubunini, ingano nuburemere biracyagarukira kubera imiterere yapakiwe hamwe nibisabwa na padi.
Ipaki ya ⑵COB: Bitewe no gusiba amapine yo hepfo hamwe na shell, paki ya cob igera ku gitsina gakabije, bigatuma paki ari nto kandi yoroshye.
5.3 Gutandukanya Ubushyuhe
Gupakira - Ahanini nakwirakwiza ubushyuhe binyuze muri padi na colloide, kandi agace ko gutandukana nubushyuhe ni bigarukira. Munsi yumucyo mwinshi no kwishora mu misozi miremire, ubushyuhe bushobora kwibanda mu gace ka chip, bigira ingaruka ku buzima no gutuza kwerekana.
⑵COB Ipaki: Chip isegitswe kuri PCB nubushyuhe irashobora gukubitwa binyuze mu kibaho cyose cya PCB. Ubu bushushanyo bwangiza cyane imikorere yubushyuhe bwo kwerekana kandi bugabanya urugero rwo kunanirwa kubera ubushyuhe bwinshi.
5.4 Ibyokurya byo kubungabunga
Gupakira: Kubera ko ibice byashyizwe yigenga kuri PCB, biraroroshye gusimbuza igice kimwe mugihe cyo kubungabunga. Ibi bifasha kugabanya ibiciro byo kubungabunga no kugabanya igihe cyo kubungabunga.
Gupakira: Kuva chip na pcb basubukuwe muri rusange, ntibishoboka gusenya cyangwa gusimbuza chip ukundi. Bimaze kuba amakosa, mubisanzwe ni ngombwa gusimbuza ikibaho cyose cya PC cyangwa gisubize mu ruganda kugirango kisane, cyongera ikiguzi n'ingorabahizi.
5.5 Ibyifuzo
Igipfukisho cya ⑴SMD: Bitewe no gukura kwayo no mu giciro cyo mu buryo buke, bikoreshwa cyane ku isoko, cyane cyane mu mishinga iboneye kandi bisaba kororana cyane kandi bisaba kwamamaza cyane no kurukuta rwa TV.
Gupakira: Bitewe n'imikorere minini no kurinda cyane, birakwiriye kugaragariza indogobe yo hejuru, irerekana amashusho rusange, mubyumba rusange nibindi bisabwa byerekana ubuziranenge hamwe nibisabwa binini. Kurugero, mubigo byateganijwe, studiyo, ibigo bikomeye byoherejwe nibindi bidukikije aho abakozi bareba ecran kuva kera, ikoranabuhanga rya cob rirashobora gutanga uburambe bworoshye kandi bwumvikana.
Umwanzuro
Ikoranabuhanga rya SMD hamwe na Cob Gupakira Cob buriwese afite ibyiza byabo byihariye hamwe na pronarios yo gusaba mumurima wayoboye. Abakoresha bagomba gupima no guhitamo ukurikije ibyo bakeneye bifatika mugihe bahisemo.
Ikoranabuhanga rya SMD hamwe nikoranabuhanga rya cob rifite ibyiza byabo. Ikoranabuhanga rya SMD rikoreshwa cyane ku isoko kubera gukura kwayo hejuru no kugarura umusaruro muke, cyane cyane mumishinga itoroshye kandi isaba korora neza. Ikoranabuhanga rya CoB, kurundi ruhande, rifite irushanwa rikomeye mu mashusho yo mu nzu yo hejuru, yerekana, hashyizweho ibyumba rusange n'izindi nzego bikabije, imikorere myiza, gutandukana kw'ubushyuhe no gukwirakwiza ubushyuhe.
