Yini i-SMT?

Iningi lama-elekthronikhi ezentengiselwano wonke amayelana nokujikeleza okuyinkimbinkimbi kokufaka ezindaweni ezincane.Ukuze wenze lokhu, izingxenye zidinga ukugxunyekwa ngokuqondile ebhodini lesifunda kunokuba zifakwe izintambo.Yilokhu empeleni okuyi-surface mount technology.

Ingabe i-Surface Mount Technology ibalulekile?

Iningi elikhulu lama-electronics anamuhla akhiqizwa nge-SMT, noma ubuchwepheshe be-surface mount.Amadivayisi nemikhiqizo esebenzisa i-SMT inenani elikhulu lezinzuzo ngaphezu kwamasekethe ahanjiswa ngendlela evamile;lawa madivayisi aziwa njengama-SMD, noma amadivaysi okukhweza ngaphezulu.Lezi zinzuzo ziqinisekise ukuthi i-SMT ilawule umhlaba we-PCB kusukela yasungulwa.

Izinzuzo ze-SMT

• Inzuzo enkulu ye-SMT ukuvumela ukukhiqizwa okuzenzakalelayo kanye ne-soldering.Lokhu kuyizindleko nokonga isikhathi futhi kuvumela isekethe engaguquki kakhulu.Ukonga ezindlekweni zokukhiqiza kuvame ukudluliselwa ekhasimendeni - okwenza kube nenzuzo kuwo wonke umuntu.
• Imigodi emincane idinga ukubhobozwa kumabhodi esekethe
• Izindleko ziphansi kunezingxenye ezilinganayo zembobo
• Noma yiluphi uhlangothi lwebhodi lesifunda lungaba nezingxenye ezibekwe kulo
• Izingxenye ze-SMT zincane kakhulu
• Ukuminyana kwengxenye ephezulu
• Ukusebenza okungcono ngaphansi kwezimo zokuzamazama nokudlidliza.
• Izingxenye zamandla amakhulu noma aphakeme azifaneleki ngaphandle uma kusetshenziswa ukwakhiwa kwe-hole.
• Ukulungisa ngesandla kungaba nzima kakhulu ngenxa yosayizi ophansi kakhulu wezingxenye.
• I-SMT ingaba yingafaneleki ezingxenyeni ezithola ukuxhunywa njalo nokunqanyulwa.

Ukungalungi kwe-SMT

Yiziphi izisetshenziswa ze-SMT?

Amadivayisi wokukhweza phezulu noma ama-SMD ngamadivayisi asebenzisa ubuchwepheshe bokukhweza phezulu.Izingxenye ezihlukahlukene ezisetshenzisiwe ziklanyelwe ngokukhethekile ukuthi zidayiswe ngokuqondile ebhodini kunokuba zifakwe izintambo phakathi kwamaphoyinti amabili, njengoba kwenzeka ngobuchwepheshe bembobo.Kunezigaba ezintathu eziyinhloko zezingxenye ze-SMT.

I-Passive SMDs

Iningi lama-SMD angenzi lutho ama-resistor noma ama-capacitor.Osayizi bamaphakheji alawa basezingeni elifanele, ezinye izakhi ezihlanganisa amakhoyili, amakristalu nezinye zivame ukuba nezidingo eziqondile.

Amasekhethi ahlanganisiwe

Ngobaulwazi oluthe xaxa mayelana namasekhethi ahlanganisiwe ngokuvamile, funda ibhulogi yethu.Ngokuphathelene ne-SMD ngokuqondile, zingahluka kakhulu ngokuya ngoxhumo oludingekayo.

Ama-Transistors nama-diode

Ama-Transistors nama-diode avame ukutholakala ephaketheni elincane lepulasitiki.Imikhondo yakha ukuxhumana futhi ithinte ibhodi.Lawa maphakheji asebenzisa imikhondo emithathu.

Umlando omfushane we-SMT

Ubuchwepheshe be-Surface Mount baqala ukusetshenziswa kabanzi ngawo-1980, futhi ukuthandwa kwabo kukhule kusukela lapho.Abakhiqizi be-PCB basheshe baqaphela ukuthi amadivaysi e-SMT asebenza kahle kakhulu ukukhiqiza kunezindlela ezikhona.I-SMT ivumela ukuthi ukukhiqizwa kwenziwe ngemishini ephezulu.Ngaphambilini, ama-PCB ayesebenzisa izintambo ukuxhuma izingxenye zawo.Lezi zintambo zazilawulwa ngesandla kusetshenziswa indlela yomgodi wokubhoboza.Izimbobo ezingaphezulu ebhodini zazixhunywe izintambo kuzo, futhi lezi zazihlanganisa izingxenye ze-electronic.Ama-PCB endabuko ayedinga abantu ukuze basize kulokhu kwakhiwa.I-SMT isuse lesi sinyathelo esinzima enqubweni.Izingxenye esikhundleni salokho zidayiselwe phezu kwamaphedi emabhodini esikhundleni salokho - yingakho 'i-surface mount'.

I-SMT iyaqhubeka

Indlela i-SMT ezinikele ngayo ekusetshenzisweni kwemishini isho ukuthi ukusetshenziswa kwanda ngokushesha embonini yonke.Kwadalwa isethi entsha yezingxenye ezihambisana nalokhu.Lezi zivame ukuba zincane kunozakwabo be- through-hole.Ama-SMD akwazile ukuba nenani lamaphinikhodi aphezulu kakhulu.Ngokuvamile, ama-SMTs nawo aminyene kakhulu kunamabhodi esekethe embobo, okuvumela izindleko eziphansi zokuhamba.Sekukonke, amadivaysi asebenza kahle kakhulu futhi ayonga.Bayakwazi ukuthuthuka kwezobuchwepheshe obekungacatshangwa ukuthi kusetshenziswa i- through-hole.
