Iyintoni inkqubo ye-SMT ye-PCBA?

• I-SMT (iTekhnoloji yeNtaba yeNtaba yeNtaba), ebizwa ngokuba yiTekhnoloji yeNtaba yeNtaba, yeyona teknoloji idumileyo nenkqubo kwishishini lendibano ye-elektroniki. Idlala indima ebalulekileyo kwi-PCB (iBhodi yeBhodi yeBhodi yeBhodi yeSijikelezi yeBhodi). Ngamazwi alula, i-PCBA licandelo elifaka izinto ezahlukeneyo ze-elektroniki kwiBhodi yeSephalo eprintiweyo (i-PCB), kunye neSMT yinkqubo ephambili yokufezekisa olu kufakelo.

Iprinta yomthengisi

• Eli linyathelo lokuqala kwinkqubo ye-SMT kwaye ifana nokwakha "isiseko" kwi-PCBA. Okokuqala, i-PCB ilungisiwe kwi-adhedch yomatshini wokushicilela. Emva koko, i-themer paste (i-paste yomgubo kunye ne-flux) iprintwe nge-mesh yentsimbi (iphepha elincinci elinepateni yokuvula) kwi-PCB apho amacandelo athengiswe khona. Le nkqubo ifuna ulawulo oluchanekileyo lwesixa se-conter paste kunye nendawo yokuprinta, njengokupeyinta isebenzisa ipeyinti kwi-canvas ngokuchaneka. Ukuba isixa senani leTyala i-Conti inkulu kakhulu, kunokubakho iingxaki ezinje ngesekethe emfutshane kwinkqubo elandelayo yeWolding; Ithambeka elincinci leTystile linokukhokelela ekubeni athengiswe buthathaka.

Icandelo leNtaba

• Emva kokuba kuprintwa i-Tepler Passing igqityiwe, ingena kwinqanaba lokuhlaselwa kwecandelo elimnandi, eliyinqanaba apho i-PCBA iqala khona "Yongeza izitena nodaka". Umatshini weNtaba, ofana ne "Elf" i-Elf "ye-Elf", inokuthatha izinto ezahlukeneyo zomhlaba (i-SMD) evela kwibhanti ephezulu yezinto eziphathekayo okanye i-SMD enesantya esiphezulu kwaye ichanekile kwi-Phb Pid . Ezi macandelo ziyahluka ngokobukhulu kwii-chip ezincinci ukuya kwii-capatitors ezinkulu ezincinci, abaqeqeshe, njalo njalo. Umatshini wokubekwa kusebenza ngokuchanekileyo, uqinisekisa ukuba icandelo ngalinye lifakwe ngqo apho kufanele ukuba libe khona, kunye ne-tarton encinci yempazamo, ngendlela yokuba abasebenzi bokwakha babeka isiqwenga ngasinye esikhethekileyo kwisakhiwo sesakhiwo.

Ukukhawulezisa ukuthengisa

• Xa izinto zifakwe kwi-PCB ngokuchanekileyo, ziya kubhala "kuvavanyo lwe-welding" -imvuza-ukhula. Le nkqubo ifana nobhaptizo oluphezulu lwe-pcba "ukuze irhwebi ichithe amaqondo aphezulu, ukuze athengise izikhonkwane ze-PCB kunye. Kwindawo ekhawulezayo yempilo, iqondo lobushushu liya kunyuka ngokuthe ngcembe kwaye linciphe ngokwejika elisexeshekileyo. Xa iqondo lobushushu likhuphuka kwindawo yokunyibilika kweTote, i-Conti iya kuba lulwelo, kwaye phantsi kwesenzo soxinzelelo lomphezulu, siya kuzalisa umsantsa phakathi kwePIN yecandelo kunye nepad, yenza unxibelelwano oluhle lombane. Xa amaqondo obushushu ahla, i-Pote Assi Disosasisisotions, izinto zilungiswe ngokuqinileyo kwi-PCB, njengamaqondo ensimbi emva kokunyanzelwa kweqondo lobushushu, edibene ngokuqinileyo nangokuqinileyo.

3.Ukulungiswa kunye nokulungiswa

• Emva kweenkqubo ezimbalwa zokuqala, i-PCBA ibisenziwa kwangaphambili, kodwa ayinakuthathwa kancinci ". Oku kulandelwa luvavanyo olungqongqo, olufana "novavanyo lomzimba olupheleleyo" lwe-PCBA. Ukuhlolwa kwe-Automated Staction (AOI) Unokutshekisha ukuba ngaba indawo yokuma kwezinto ichanekile, nokuba kukho izinto ezilahlekileyo, nokuba kukho izinto ezilahlekileyo, nokuba ngaba uMthengi uncamathisela i-welding, nakwezinye iingxaki ezinokwenzeka. Ukuba kufunyenwe i-PCBA enesiphene, kufuneka ilungiswe. Ukulungiswa kufana "nokunyanga" i-PCBA egulayo. Iitekhnoloji ziya kusebenzisa izixhobo ezizodwa kunye nezixhobo zokulungisa iinxalenye eziphosakeleyo, njengokungekho mthethweni ilungelo lokuziqhelanisa okanye ukutshintsha izinto ezonakeleyo, ukuqinisekisa ukuba i-PCBA nganye ifezekisa i-picka elilandelayo okanye ihanjiswe Umthengi.

4.Kuphela konke , itekhnoloji ye-SMT yinkqubo echanekileyo nentsomi kwinkqubo yemveliso yePCBA. Ukusuka kulwakhiwo lweSiseko loThengiso lweThrinta, ukuya kwikhombeko yezinto ezinamacandelo, ukungcungcutheka okuphambili kwemveliso yemveliso, kunye nenkxaso yokugqibela kunye nenkxaso yokulungisa, ikhonkco ngalinye linxibelelana kakhulu kwaye linxibelelana. Ukumiliselwa ngokuchanekileyo kunye nokunxibelelana okusebenzayo kwikhonkco ngalinye kunokuqinisekisa ukukhutshwa komgangatho omkhulu we-PCB, hlangabezana neemveliso ezingqongqo zemveliso yombane, uzinzo kunye nokukhuthaza ukuphuculwa kweshishini lonke le-elektroniki, kwaye ubeke isiseko Isiseko sokuzalwa kweemveliso ezininzi zeTeknoloji ephezulu.
