Ithetha ukuthini i-SMT? IsiKhokelo esiGqibeleleyo kwiTekhnoloji yoMphezulu weNtaba

Ukuba ukhe wazibuza ukuba i-elektroniki yanamhlanje yakhiwe njani ngokukhawuleza kwaye incinci, sele ulichukumisile ihlabathiSMT.

Ngoko ke masiphendule umbuzo ngokuthe ngqo:

I-SMT ithetha i-Surface Mount Technology-inkqubo yanamhlanje yokwakha iibhodi zeesekethe ngokubeka izinto ezincinci ze-elektroniki ngokuthe ngqo kumphezulu we-PCB kwaye uzithengise kwi-oveni yokuphinda iqhume. Xa kuthelekiswa neendlela zokuphuma emngxunyeni, i-SMT yenza ukuba iimveliso ezincinci, ukudibanisa okuzenzekelayo ngokukhawuleza, ukuthembeka okuphezulu, kunye noyilo olumacala amabini.

Kufuphi,I-SMT bubuchwepheshe obenza izinto zombane zala maxesha zikwazi ukwenzeka- ukusuka kwii-smartphones kunye neziboniso ze-LED ukuya kwiimoto kunye nezixhobo zonyango.

Yintoni ngokwenene i-SMT

Phambi kwe-SMT, icandelo ngalinye linezikhokelo zetsimbi ezinde ezityhalwe kwimingxunya kwi-PCB zaza zathengiswa kwelinye icala.
Loo ndlela yakudala ibizwaItekhnoloji yomngxuma (THT)— uyacotha, mkhulu, kwaye usebenza nzima.

I-SMT ithetha i-Surface Mount Technology-inkqubo yanamhlanje yokwakha iibhodi zeesekethe ngokubeka izinto ezincinci ze-elektroniki ngokuthe ngqo kumphezulu we-PCB kwaye uzithengise kwi-oveni yokuphinda iqhume. Xa kuthelekiswa neendlela zokuphuma emngxunyeni, i-SMT yenza ukuba iimveliso ezincinci, ukudibanisa okuzenzekelayo ngokukhawuleza, ukuthembeka okuphezulu, kunye noyilo olumacala amabini.

Akusekho mingxunya, akusekho soldering ngesandla - icocekile, iyakhawuleza, idityaniswe ngokuzenzekelayo.

Leyo yintsingiselo yokwenyani ye-SMT:

Ukuchaneka okuphezulu, indlela ezenzekelayo yokwakha iibhodi zeesekethe ngokubeka kunye namacandelo e-soldering ngqo kwindawo yebhodi.

Imvelaphi ye-SMT

Ibali le-Surface Mount Technology libuyela emva ngaphezulu kwesiqingatha senkulungwane.
Ngeminyaka yee-1960,IBMwaqala ukuzama inkqubo ebizwaUkunyuka kwePlanar, eyayiyindlela yokuqala yokubeka amacandelo ngokuthe ngqo kwiibhodi zesekethe eziprintiweyo. Kwiminyaka engamashumi amabini alandelayo, le ngcamango yavela kwinto esiyibiza ngokuSMT.

Phakathi kwiminyaka yoo-1970, abavelisi babesele besebenzisa ukunyuswa komhlaba ukuvelisaiiwotshi kunye nezixhobo zokubala, ukusebenzisa indibano encinci, ekhawulezayo.
Kodwa akuzange kube ngowe-1980s - xa izinto ze-elektroniki zaye zancitshiswa kakhulu - ukuba i-SMT yaqala ngokwenene.

Ngu1986, izixhobo ezibekwe phezu komhlaba (SMDs) zibalwa malunga10%kuzo zonke iindibano ze-elektroniki.
Njekwiminyaka emine kamva, baye babaindlela elawulayoyokwenziwa kwePCB kwihlabathi liphela.

Ngexesha lokuzivelela, amagama amaninzi ahambelanayo aqhelekile kwishishini:

• SMD-Isixhobo sokuNyusa uMphezulu

• I-SMA– INdibano yeNtaba yeSurface-Mount

• SMC– iSahlulo sokuNyuma komphezulu

• ISINALA ESINGAMABANGA APHANTSI-Ipakethe yoMphezulu weNtaba

• WE– Surface-Mount Izixhobo

Ngokudibeneyo, la magama achaza i-ikhosistim eyenza i-SMT yaba sisiseko sokwenziwa kombane wale mihla.

Isebenza njani i-SMT - Inyathelo ngenyathelo

Makhe sijonge okwenzekayo kumgca wemveliso we-SMT.
Nantsi indlela ezalwa ngayo i-mainboard yefowuni yakho okanye ikhadi lolawulo lwe-LED:

1. Ushicilelo lwe-Solder Paste

Umaleko obhityileyo we-solder paste usetyenziswa kwi-PCB usebenzisa i-stencil yentsimbi.
Oku kuncamatheliswa kuya kunyibilika kamva kwaye kubambe amacandelo kwindawo.

2. Khetha kwaye ubeke

Oomatshini berobhothi babizwaiinkqubo zokukhetha kunye nendawochola amacandelo e-SMD kwiireli kwaye uwabeke ngokuchanekileyo kwi-solder pads pads.
Umatshini ngamnye unokukhwela amashumi amawaka eenxalenye ngeyure.

3. I-Soldering kwakhona

I-PCB idlula kwi-areflow oven, apho ubushushu bunyibilika i-solder paste, idibanisa inxalenye nganye ngokusisigxina kwibhodi.
Emva kokupholisa, yonke idibeneyo iqinile kwaye inokwethenjelwa.

4. Ukuhlolwa noVavanyo

Iikhamera kunye nabenzi boluvo (kwiI-AOIokanye iinkqubo ze-X-reyi) khangela yonke i-solder joint ukuze ichanekile.
Ukuba kukho isiphene, siphinda sisetyenzwe ngesandla ziinjineli ezinezakhono.

Yonke loo nkqubo - ukusuka kwibhodi engenanto ukuya kwisekethe epheleleyo - ithatha imizuzu embalwa kuphela.

Yintoni eyenza i-SMT ibaluleke kangaka

Unokucinga nge-SMT njengomqolo wokwenziwa kombane wale mihla.
Nasi isizathu sokuba kubalulekile:

• Iminiaturization:Ivumela amawaka amacandelo ukuba alingane kwiibhodi ezincinci.

• Ukuzenzekela:Oomatshini benza umsebenzi, benza imveliso ngokukhawuleza kwaye ingaguquguquki.

• Ukusebenza:Iindlela zombane ezimfutshane zithetha ukulahleka komqondiso omncinci kunye nokuthembeka okungcono.

• Ukusebenza kakuhle kweendleko:Nje ukuba imiselwe, i-SMT ithoba iindleko zabasebenzi kunye nezinto eziphathekayo kakhulu.

• Ukuba bhetyebhetye:Amalungu angaxhonywa kumacala omabini ePCB.

Ngaphandle kwe-SMT, ngekhe sibe neelaptops ezixineneyo, ii-smartwatches, okanye iindonga ze-LED — yonke into isenokukhangeleka ngathi yeyoo-1980s.

I-SMT vs. SMD — Yintoni Umahluko?

Kulapho abantu bahlala bebhideka khona.

• SMT = Umphezulu weTekhnoloji yeNtaba→ iinkqubo okanye indlela

• SMD = IsiXhobo sokuKhuphuka komphezulu→ ieyona nxalenyeisetyenziswe kuloo nkqubo

Ngoko ke, i-SMTNjaniyenziwe, kwaye i-SMD iyeIntoniibekwa.
Cinga nge-SMT njengekhitshi, kunye nee-SMD njengezithako.

SMT vs. Through-Hole Technology

Umngxuma wokutyhutyha usenayo indawo yayo-yeziqhagamshelo, ii-capacitors ezinkulu, okanye iimodyuli zamandla-
kodwa kuyo yonke enye into,I-SMT ngumgangatho.

Imizekelo yokwenyani yehlabathi ye-SMT esebenzayo

Uya kufumana i-SMT kuyo yonke indawo:

• Ii-smartphones:yonke i-microchip kunye ne-resistor kwibhodi yefowuni yakho ibekwe phezulu.

• Ukukhanya kwe-LED:I-SMD2835 kunye nee-LED ze-SMD5050 zifakwe kusetyenziswa imigca ye-SMT.

• Iisistim zeemoto:abalawuli beenjini, iziboniso zedeshibhodi, abenzi boluvo.

• Izixhobo zonyango:iimonitha ezidibeneyo kunye nezixhobo zokuxilonga.

• Ulawulo lwemizi-mveliso:iirobhothi, abenzi boluvo, iinkqubo ezizenzekelayo.

Ngokusisiseko, ukuba inebhodi yesekethe, yakhiwe nge-SMT.

Kwenzeka ntoni Ngaphakathi kumgca we-SMT

Umgca opheleleyo wemveliso we-SMT uhlala ubandakanya:

1. Umlayishi wePCB– iibhodi feeds ngokuzenzekelayo.

2. Isishicileli seNcamathelo ye-Solder– iprinta iipateni zokuncamathisela ezichanekileyo.

3. Khetha kwaye ubeke umatshini- ibeka onke amalungu e-SMD.

4. Hlaziya i-Oven– inyibilikisa i-solder kwaye itshixe iindawo kwindawo yazo.

5. I-AOI (uHlolo oluzenzekelayo lwaMacho)- iitshekhi zesolder okanye iimpazamo zokubeka.

6. Umkhupheli- iibhodi ezigqityiweyo zilungele ukuvavanywa.

Yinkqubo ezenzekelayo ngokupheleleyo eqhuba imini nobusuku kwimizi-mveliso kwihlabathi jikelele.

Ikamva le-SMT

Iifektri zale mihla ze-SMT ziya zisiba nobuchule ngakumbi.
I-AI kunye nokufunda koomatshini ngoku kunceda iinkqubo zokuhlola zibone iziphene ngokuzenzekelayo.
Itekhnoloji ye-IoT ivumela wonke umatshini ukuba anxibelelane idatha yexesha langempela kwiinjineli.
Ugcino oluqikelelweyo lunokumisa ukophuka ngaphambi kokuba kwenzeke.

Ngamanye amazwi,I-SMT isuka kwi-automation ukuya kubukrelekrele-Intliziyo yokuvelisa ngobuchule.

Ukubuyisela kwakhona ngokukhawuleza: Ithetha ukuthini i-SMT?

Ke, ukuba umntu uyakubuza kwakhona"Ithetha ukuthini i-SMT?",
unokuphendula ngesivakalisi esinye esicacileyo:

"I-SMT ithetha iTekhnoloji yoMphezulu weMount - inkqubo ezenzekelayo yokwakha iibhodi zesekethe ngokufaka izinto ngokuthe ngqo kumphezulu webhodi."

Nguwo lowo umfanekiso opheleleyo — ulula, uchanekile kwaye uyasebenziseka.
