SMT iyo Faa'iidada ku jirta Guddiyada Wareegga

Waa maxay SMT? Waa maxay sababta SMT guud ahaan loo aqbalay, loo aqoonsaday oo loo dhiirrigeliyay warshadaha elektiroonigga ah marka ay soo baxdo? Maanta Capel ayaa mid mid kuu kala saari doona.

Surface Mount Technology:

Waa in horay loo dejiyo budada daawaha u eg (koollada alxanka ee gaaban) dhammaan suufyada lagu xirayo PCB-ga iyadoo la daabacayo, dahaarka barta, ama buufinta, ka dibna qaybaha dusha sare ee dusha sare (SMC/SMD)) booska la cayimay ee korka PCB-ga, ka dibna dhamaystir dib-u-dhajinta iyo isku-xidhka koollada alxanka ee dhammaan kala-goysyada alxanka korka ee foornada gaarka ah ee la cayimay si loo dhamaystiro dhammaan habka isku xirka PCBA-ga. Ururinta tignoolajiyadan waxaa lagu magacaabaa tignoolajiyada dusha sare, magaca Ingiriisiga waa "Surface Mount Technology, SMT oo gaaban.

Sababtoo ah alaabada elektiroonigga ah ee ay soo ururisay SMT waxay leeyihiin faa'iidooyin taxane ah oo dhammaystiran sida cabbir yar, tayo wanaagsan, kalsooni sare, habka wax-soo-saarka tooska ah, wax-soo-saarka sare, qeexida badeecada joogtada ah, iyo waxqabadka qiimaha wanaagsan, si weyn ayaa loo aqoonsaday oo ay doorbideen qalabka elektiroonigga ah. warshadaha. Marka, ka dib marka alaabtu qaadato SMT, faa'iidooyinkee ayaa laga heli karaa alaabtu?

Faa'iidooyinka isticmaalka SMT ee alaabta:

1. Cufnaanta fadhiga sare: Guud ahaan, marka la barbardhigo habka TTHT, isticmaalka SMT wuxuu yarayn karaa mugga alaabta elektaroonigga ah 60% wuxuuna yareeyaa miisaanka 75%;

2. Isku halaynta sare: Labada baasaska ugu horreeya ee kala-goysyada alxanka ee wax soo saarka alaabta iyo wakhtiga celceliska ee u dhexeeya guuldarrada (MTBF) ee alaabta ayaa si weyn loo hagaajiyay;

3. Sifooyin wanaagsan oo soo noqnoqonaya: Maadaama SMC / SMD badanaa aysan lahayn hoggaan ama hoggaan gaaban, saameynta inductance parasitic iyo capacitance ayaa la yareeyaa, sifooyinka sare ee wareegga wareegga ayaa la wanaajiyaa, iyo wakhtiga gudbinta calaamaduhu waa la yareeyaa;

4. Kharash yar: Meesha PCB ee loo isticmaalo SMT waa 1/12 oo kaliya ee aagga THT oo leh shaqo isku mid ah. SMT waxay isticmaashaa PCB si ay u yarayso qodista badan, taas oo yaraynaysa kharashka wax soo saarka PCB; hoos u dhigista mugga iyo tayada ayaa si weyn u badbaadisa qiimaha baakadaha alaabta iyo gaadiidka; qiimaha guud ee badeecada aad ayaa loo dhimay, waxaana kor loo qaaday tartanka balaadhan ee badeecada suuqa. xoog;

5. Fududeynta wax-soo-saarka otomaatiga ah: Wax-soo-saarka guud, si buuxda ayaa loo farsamayn karaa, oo leh wax-soo-saar sare, awood weyn, tayo xasilloon, kalsooni sare, iyo kharashka wax-soo-saarka oo hooseeya.

Shenzhen Capel Technology Co., Ltd. ayaa aasaasay warshad wax soo saarka guddiga wareegga tan iyo 2009 oo waxay bixisaa adeegyada shirka SMT PCB. 15kii sano ee la soo dhaafay, waxa ay uruursatay khibrad qani ah, koox xirfad leh, mashiino iyo qalab horumarsan, iyo awoodo wax soo saar horumarsan. Waxay u xallisay dhibaatooyin kala duwan ee mashaakilaadka mashruuca macaamiisha.
