I-SMT kunye neNzuzo yayo kwiiBhodi zeSekethe

Yintoni i-SMT? Kutheni le nto i-SMT yamkelwe ngokubanzi, yamkelwa kwaye yakhuthazwa lishishini lezombane xa sele iphumile? Namhlanje iCapel izakukhuphela yona nganye nganye.

ITekhnoloji yoMphezulu weMount:

Kukuseta kwangaphambili umgubo we-alloy wokuncamathisela (i-solder paste ngokufutshane) kuzo zonke iipads eziza kudityaniswa kwi-PCB ngokushicilela, ukugquma indawo, okanye ukutshiza, kwaye emva koko kufakwe izinto eziphezulu (SMC/SMD)) indawo ekhankanyiweyo kumphezulu we-PCB, kwaye emva koko ugqibezele ukunyibilika kunye nokudityaniswa kwe-solder paste kuzo zonke izihlanganisi ezikhwelayo kwiziko elikhethekileyo elichaziweyo ukugqiba yonke inkqubo yoqhagamshelo lwePCBA. Ingqokelela yezi teknoloji ibizwa ngokuba yi-surface mount technology, igama lesiNgesi yi “Surface Mount Technology, SMT ngokufutshane.

Ngenxa yokuba iimveliso ze-elektroniki ezihlanganiswe yi-SMT zinoluhlu lweenzuzo ezibanzi ezifana nobukhulu obuncinci, umgangatho omhle, ukuthembeka okuphezulu, inkqubo yokuvelisa ngokuzenzekelayo, imveliso ephezulu, imilinganiselo yemveliso engaguqukiyo, kunye nokusebenza kweendleko ezigqwesileyo, ziye zamkelwa ngokubanzi kwaye zithandwa yi-elektroniki. ishishini. Ke, emva kokuba imveliso yamkele i-SMT, zeziphi iingenelo ezinokuzuzwa yimveliso?

Izinto ezilungileyo zokusebenzisa i-SMT kwiimveliso:

1. Ubuninzi bendibano ephakamileyo: Ngokuqhelekileyo, xa kuthelekiswa nenkqubo ye-THT, ukusetyenziswa kwe-SMT kunokunciphisa umthamo weemveliso ze-elektroniki nge-60% kunye nokunciphisa ubunzima nge-75%;

2. Ukuthembeka okuphezulu: Zombini ireyithi yokupasa yokuqala ye-solder joints kwimveliso yemveliso kunye nexesha eliphakathi phakathi kokungaphumeleli (MTBF) kweemveliso ziphuculwe kakhulu;

3. Iimpawu ezilungileyo ze-high-frequency: Ekubeni i-SMC / i-SMD ngokuqhelekileyo ayinayo isikhokelo okanye isikhokelo esifutshane, impembelelo ye-parasitic inductance kunye ne-capacitance iyancitshiswa, iimpawu eziphezulu ze-frequency zesekethe ziphuculwe, kwaye ixesha lokudlulisa umqondiso lifutshane;

4. Ixabiso eliphantsi: Indawo yePCB esetyenziselwa i-SMT yi-1/12 kuphela yendawo yeTHT enomsebenzi ofanayo. I-SMT isebenzisa i-PCB ukunciphisa ukugrumba okuninzi, okunciphisa iindleko zokwenza i-PCB; ukunciphisa umthamo kunye nomgangatho kusindisa kakhulu iindleko zokupakishwa kwemveliso kunye nokuthutha; Ixabiso lilonke lemveliso liyancipha kakhulu, kwaye ukhuphiswano olubanzi lwemveliso kwimarike luyandiswa. amandla;

5. Ukuququzelela ukuveliswa kwemveliso : Kwimveliso yobuninzi, iyakwazi ukuzenzekelayo ngokupheleleyo, kunye nemveliso ephezulu, umthamo omkhulu, umgangatho ozinzileyo, ukuthembeka okuphezulu, kunye neendleko eziphantsi ezidibeneyo zokuvelisa.

I-Shenzhen Capel Technology Co., Ltd. iseke imveliso yebhodi yesekethe ukususela ngo-2009 kwaye ibonelela ngeenkonzo zendibano ye-SMT PCB. Kule minyaka ili-15 idlulileyo, iqokelele amava atyebileyo, iqela leengcaphephe, oomatshini abakumgangatho ophezulu kunye nezixhobo, kunye nobuchule obuphambili bokuvelisa. Isombulule iingxaki ezahlukeneyo kwingxaki yeprojekthi yabathengi.
