Yintoni i-SMT?

Uninzi lwee-elektroniki zentengiso zimalunga neesekethe ezintsonkothileyo zokufakwa kwiindawo ezincinci.Ukwenza oku, amacandelo kufuneka afakwe ngokuthe ngqo kwibhodi yesekethe kunokuba afakwe iingcingo.Eyona nto iyiyo itekhnoloji ye-surface Mount.

Ngaba iTekhnoloji yeMount Mount ibalulekile?

Uninzi lwezixhobo zombane zanamhlanje zenziwa nge-SMT, okanye itekhnoloji yokubeka umphezulu.Izixhobo kunye neemveliso ezisebenzisa i-SMT zinenani elikhulu leenzuzo ngaphezu kweesekethe ezihanjiswa ngokwesiko;ezi zixhobo zaziwa njenge-SMDs, okanye izixhobo zokunyusela phezulu.Ezi nzuzo ziye zaqinisekisa ukuba i-SMT iye yalawula ihlabathi le-PCB ukususela ekuqulunqweni kwayo.

Izinto eziluncedo ze-SMT

• Inzuzo ephambili ye-SMT kukuvumela imveliso ezenzekelayo kunye ne-soldering.Oku kuziindleko kunye nokonga ixesha kwaye kukwavumela isekethe ehambelana kakhulu.Ugcino kwiindleko zokwenziwa kwemveliso lusoloko lugqithiselwa kumthengi – luyenza ibe luncedo kumntu wonke.
• Imingxuma encinci kufuneka igrunjwe kwiibhodi zeesekethe
• Iindleko zingaphantsi kuneendawo ezilingana nomngxuma
• Naliphi na icala lebhodi yesekethe linokuba namacandelo abekwe kuwo
• Amacandelo e-SMT mancinci kakhulu
• Ukuxinana kwecandelo eliphezulu
• Ukusebenza ngcono phantsi kweemeko zokungcangcazela kunye nokungcangcazela.

Izinto ezingeloncedo kwi-SMT

• Amalungu amakhulu okanye anamandla amakhulu awafanelekanga ngaphandle kokuba kusetyenziswe ulwakhiwo lokuphuma ngomngxuma.
• Ukulungisa ngesandla kunokuba nzima kakhulu ngenxa yobukhulu obuphantsi kakhulu bamalungu.
• I-SMT isenokungafaneleki kumacandelo afumana ukuqhagamshelwa rhoqo kunye nokuqhawulwa.

Ziziphi izixhobo ze-SMT?

Izixhobo zokunyuswa komphezulu okanye ii-SMD zizixhobo ezisebenzisa itekhnoloji yokunyuswa komhlaba.Amacandelo ahlukeneyo asetyenzisiweyo ayilelwe ngokukodwa ukuba athengiswe ngokuthe ngqo ebhodini kunokuba abe neentambo phakathi kwamanqaku amabini, njengoko kunjalo ngeteknoloji yomngxuma.Kukho iindidi ezintathu eziphambili zamacandelo e-SMT.

Ii-SMDs ezingenamsebenzi

Uninzi lwee-SMD ezingasebenziyo zizixhasi okanye ii-capacitors.Ubungakanani bepakethe yezi zinto zisemgangathweni, amanye amacandelo abandakanya iikhoyili, iikristale kunye nezinye zikholisa ukuba neemfuno ezithe ngqo.

Iisekethe ezidibeneyo

Kubaulwazi oluninzi malunga neesekethe ezidibeneyo ngokubanzi, funda iblogi yethu.Ngokunxulumene ne-SMD ngokuthe ngqo, zinokwahluka kakhulu ngokuxhomekeke kunxibelelwano olufunekayo.

Transistors kunye diodes

I-Transistors kunye ne-diode zihlala zifumaneka kwiphakheji encinci yeplastiki.Iinkokeli zenza uqhagamshelo kwaye zichukumise ibhodi.Ezi phakheji zisebenzisa iintambo ezintathu.

Imbali emfutshane ye-SMT

Itekhnoloji yeMount Mount yasetyenziswa ngokubanzi ngeminyaka yoo-1980, kwaye ukuthandwa kwayo kukhule ukusuka apho.Abavelisi be-PCB bakhawuleza baqonda ukuba izixhobo ze-SMT zisebenza kakuhle kakhulu ukuvelisa kuneendlela ezikhoyo.I-SMT ivumela ukuba imveliso yenziwe ngoomatshini kakhulu.Ngaphambili, iiPCB bezisebenzise iingcingo ukudibanisa izinto zazo.Ezi ngcingo zazilawulwa ngesandla kusetyenziswa indlela yokuphuma komngxuma.Imingxuma engaphezulu ebhodini yayineengcingo eziphothiweyo, yaye ezi zinto zazidibanisa izinto ze-elektroniki.IiPCB zesiNtu zazifuna abantu ukuba bancedise kule mveliso.I-SMT isuse eli nyathelo linzima kwinkqubo.Izixhobo endaweni yoko zathengiswa kwiiphedi ezikwiibhodi endaweni yoko - kungoko 'indawo yokunyuswa komphezulu'.

I-SMT iyaqhubeka

Indlela eyaboleka ngayo iSMT kumatshini yayithetha ukuba ukusetyenziswa kwasasazeka ngokukhawuleza kulo lonke ishishini.Iseti entsha epheleleyo yamacandelo yenziwe ukuba ikhaphe oku.Ezi zihlala zincinci kunezo zihamba nomngxuma.Ii-SMDs zikwazile ukuba nenani eliphezulu lepin.Ngokubanzi, ii-SMTs zikwaxinene ngakumbi kuneebhodi zesekethe eziphuma emngxunyeni, ezivumela iindleko zothutho ezisezantsi.Ngokubanzi, izixhobo zisebenza ngakumbi kwaye zinoqoqosho.Bayakwazi ukuqhubela phambili kwezobuchwepheshe obungenakucingelwa ngokusebenzisa umngxuma.

Isetyenziswa kwi-2017

Indibano yentaba yomphezulu iphantse yalawula ngokupheleleyo inkqubo yokudala yePCB.Akunjalo nje kuphela ukuvelisa ngokufanelekileyo, kunye nokuncinci ukuthutha, kodwa ezi zixhobo zincinci zikwasebenza kakhulu.Kulula ukubona ukuba kutheni imveliso yePCB iqhubekile isuka kwindlela enentambo yomngxunya.
