SMT isobanura iki?

Mubikorwa bya elegitoroniki bigezweho, birashoboka ko wahuye namagambo ahinnyeSMT- ariko mubyukuri bivuze iki?
SMT isobanuraIkoranabuhanga rya Surface, uburyo bwimpinduramatwara bukoreshwa muguteranya imiyoboro ya elegitoronike neza, neza, kandi murwego.

Ni umusingi inyuma yibikoresho hafi ya byose ukoresha uyumunsi - kuva kuri terefone zigendanwa na mudasobwa zigendanwa kugeza amatara ya LED, sisitemu yimodoka, nibikoresho byinganda.

Ibisobanuro bya SMT

SMT (Ikoranabuhanga rya Surface Umusozi)nuburyo bwo kubyara imiyoboro ya elegitoronike ibice birimoYashizwe hejuruby'ibibaho byacapwe (PCBs).

Mbere yuko SMT iba ibisanzwe, abayikora bakoreshejeBinyuze mu buhanga bwa tekinoroji (THT)- buhoro, inzira yibikorwa byinshi bisaba gucukura umwobo muri PCB no gushiramo kuyobora.

Muri SMT, izo kuyobora zasimbuwe nakurangiza ibyuma cyangwa amakariso, bigurishwa mu buryo butaziguye hejuru yubuyobozi ukoresheje paste paste hamwe nimashini zishyirwaho zikoresha.

Impamvu SMT Yasimbuye Gakondo Binyuze mu Nteko

Guhindura kuva muri THT kugera kuri SMT byatangiye mu myaka ya za 1980 kandi byahise bihinduka isi yose.
Dore impamvu:

Muri make,SMT yakoze ibikoresho bya elegitoroniki bito, byihuse, kandi bihendutse- utabangamiye imikorere.

Uyu munsi, hafi90% by'inteko zose za elegitoronikibyakozwe hakoreshejwe tekinoroji ya SMT.

Uburyo inzira ya SMT ikora

AnUmurongo wa SMTni sisitemu yimikorere ikora aho PCB ziteranijwe neza kandi byihuse.
Uburyo busanzwe bwa SMT burimoibyiciro bitandatu by'ingenzi:

1. Icapiro rya Solder

Mucapyi yerekanakugurishakuri padi ya PCB.
Iyi paste irimo imipira mito yo kugurisha imipira ihagarikwa muri flux - ikora nkibifata kandi ikayobora.

2. Gushyira Ibigize

Imashini zitoranya-zishyira mu buryo bwikora zishyira uduce duto twa elegitoronike (résistoriste, IC, capacator, nibindi) kuri paje yapfunditswe.

3. Kugaragaza Kugurisha

PCB yose inyura akwerekana itanura, aho umugurisha paste ashonga kandi agakomera, guhuza burundu buri kintu.

4. Kugenzura (AOI / SPI)

Igenzura ryikora ryikora (AOI) na Solder Paste Kugenzura (SPI) sisitemu igenzura inenge nko kudahuza, ikiraro, cyangwa kubura ibice.

5. Kwipimisha

Ikizamini cyamashanyarazi nigikorwa cyemeza ko buri kibaho cyateranijwe gikora neza mbere yuko cyimukira mu nteko yanyuma.

6. Gupakira cyangwa gutwikira neza

PCB zirangiye zashizweho kugirango zirinde cyangwa zinjizwe mubikoresho bya elegitoroniki byarangiye.

Ibikoresho by'ingenzi bikoreshwa mu musaruro wa SMT

Umurongo wa SMT ugizwe nimashini nyinshi zikomeye zikorana nta nkomyi:

Izi mashini zikunze guhuzwa na sisitemu yo kugenzura ubwenge kugirango tunoze neza kandi neza - igice cyaInganda 4.0 ubwihindurizemu gukora ibikoresho bya elegitoroniki.

Ibigize Rusange muri SMT

SMT yemerera ubwoko butandukanye bwibigize, harimo:

• Kurwanya hamwe na capacator (SMDs)- ibisanzwe kandi bito cyane.

• Imiyoboro ihuriweho (IC)- microprocessor, chip yo kwibuka, kugenzura.

• LED hamwe na sensor- kumurika no kumenya.

• Umuhuza na tristoriste- verisiyo yoroheje ya sisitemu yihuta.

Ibi bice bizwi hamwe nkaSMDs (Ibikoresho-Ubuso-Ibikoresho).

Ibyiza bya SMT

Kuzamuka kwa SMT byahinduye uburyo ibikoresho bya elegitoroniki byakozwe kandi bikozwe.
Ibyiza byayo birenze kure umuvuduko gusa:

Aller Ibikoresho bito kandi byoroshye

Ibigize birashobora gushirwa kumpande zombi za PCB, bigatuma igishushanyo mbonera, igishushanyo mbonera gishoboka.

Gukora neza cyane

Imirongo yuzuye ya SMT irashobora guteranya ibihumbi nibice kumasaha hamwe nabantu batabigizemo uruhare.

Performance Imikorere myiza y'amashanyarazi

Inzira ngufi zerekana inzira zisobanuraurusaku ruke, ibimenyetso byihuse, nakwizerwa kurushaho.

Kugabanya ibiciro byumusaruro

Automation igabanya amafaranga yumurimo kandi ikongera igipimo cyumusaruro, biganisha ku gukora neza.

Guhinduka mugushushanya

Ba injeniyeri barashobora guhuza ibikorwa byinshi mumwanya muto - gushoboza ibintu byose uhereye kumashanyarazi yambarwa kugeza kumashanyarazi agezweho.

Imipaka n'imbogamizi za SMT

Nubwo SMT ari urwego rwinganda, ntabwo rufite ibibazo:

• Gusana intoki bigoye- ibice ni bito kandi bipakiye cyane.

• Ubushyuhe bukabije- kugurisha ibicuruzwa bisaba kugenzura neza ubushyuhe.

• Ntabwo ari byiza kubihuza binini cyangwa ibice bya mashini- ibice bimwe na bimwe biracyakenewe binyuze mu mwobo kugirango imbaraga.

Kubera izo mpamvu, imbaho ​​nyinshi uyumunsi zikoresha auburyo bwa Hybrid, guhuza SMT na THT aho bikenewe.

Imikorere-Isi Porogaramu ya SMT

Ikoranabuhanga rya SMT rikora hafi ya byose mubikorwa bya elegitoroniki bigezweho:

Hatariho SMT, ibyuma bya elegitoroniki byoroshye kandi bikomeye ntabwo byashoboka.

Kazoza ka SMT: Ubwenge nibindi Byikora

Uko ikoranabuhanga rigenda ryiyongera, inganda za SMT zikomeje gutera imbere.
Ibisekuruza bizakurikiraho SMT imirongo irimo:

• Kugaragaza inenge ishingiye kuri AIyo guhinduranya ubuziranenge bwikora

• Ibiryo byubwenge no kubungabunga ibintuKugabanya igihe

• Guhuza amakuruhagati ya SPI, AOI, n'imashini zo gushyira

• Miniaturisation- gushyigikira 01005 hamwe na micro-LED inteko

Ejo hazaza ha SMT iri muburyo bwa digitale yuzuye hamwe na sisitemu yo kwiyigisha ishobora guhinduka mugihe nyacyo cyo kuzamura umusaruro no kugabanya imyanda.

Icyo SMT isobanura

Noneho,SMT isobanura iki?
Ntabwo arenze ijambo ryo gukora - ryerekana ihinduka rikomeye muburyo ikiremwamuntu cyubaka ibikoresho bya elegitoroniki.

Ikoranabuhanga rya Surface Mount Technology ryashobotse:

• Ibikoresho bito kandi byihuse,

• Gukora neza cyane, kandi

• Ikoranabuhanga ryoroshye kuri buri wese.

Kuva kuri terefone ya terefone yawe kugeza kuri robo yinganda nibikoresho byubuvuzi, SMT nurufatiro rutagaragara ruha imbaraga isi yacu ya none.
