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 wealloyi oncamathelayo (i-solder paste ngokufutshane) kuzo zonke iipads eziza kudityaniswa kwi-PCB ngokushicilela, ukugquma indawo, okanye ukutshiza, emva koko kunyuswe umphezulu (SMC/SMD)) kwindawo ekhankanyiweyo kumphezulu wePCB, kwaye emva koko ugqibezele ukunyibilikisa kunye nokudityaniswa kwe-solder incence yokunamathisela kwisixhobo esikhethekileyo esicacisiweyo kuyo yonke intlama ye-solder kwi-joint yokudibanisa ukuze ugqibezele yonke into. 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 lishishini lombane. 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.
