Fumax waxay ku qalabeysan tahay mashiinada SMT ee bartamaha / xawaaraha sare leh ee ugu fiican leh soo saar maalinle ah oo qiyaastii ah 5 milyan oo dhibic.

Waxyaabaha kale ee aan ka ahayn mashiinnada ugu fiican, waxaan la kulannay kooxda SMT sidoo kale waxay fure u yihiin bixinta alaab tayo fiican leh.

Fumax waxay sii wadaa maalgashiga mashiinada ugu fiican iyo xubnaha kooxda weyn.

1. SMT:

Teknolojiyada dusha sare, oo loo yaqaan SMT, waa tiknoolajiyad koronto oo elektaroonik ah oo ku dhejisa qaybaha elektarooniga ah sida iska caabiyaasha, kaabayaasha, transistorrada, wareegyada isku dhafan, iwm ee looxyada daabacan ee daabacan kuna sameeya isku xirnaanta korantada iyadoo la iibinayo.

2. Faa'iidada SMT:

Wax soo saarka SMT waxay leeyihiin faa'iidooyinka qaab dhismeedka is haysta, cabbirka yar, caabbinta gariirka, iska caabinta saameynta, astaamaha soo noqnoqda ee wanaagsan iyo waxtarka wax soo saarka sare. SMT waxay fadhiisatay boos geedi socodka shirkii gudiga wareegga.

3. Talaabooyinka ugu badan ee SMT:

Nidaamka wax soo saarka SMT guud ahaan waxaa ku jira saddex tallaabo oo waaweyn: daabacaadda dhejiska dhejiska, meelaynta iyo dib u bixinta qashinka. Khadadka wax soo saarka SMT oo dhameystiran oo ay kujiraan qalabka aasaasiga ah waa inay kujiraan seddex qalab oo waaweyn: daabacaadda daabacaadda, mashiinka meeleynta SMT ee mashiinka wax soosaarka iyo mashiinka alxanka dib udaya. Intaa waxaa dheer, marka loo eego baahiyaha dhabta ah ee wax soo saarka kala geddisan, waxaa sidoo kale jiri kara mashiinno wax lagu dhejiyo, qalabka baaritaanka iyo qalabka nadaafadda guddiga PCB. Qaabeynta iyo xulashada qalabka khadadka soosaarka SMT waa in lagu tixgeliyaa iyadoo lagu darayo baahiyaha dhabta ah ee wax soo saarka wax soo saarka, xaaladaha dhabta ah, la qabsiga, iyo soosaarida qalabka casriga ah.

5. Farqiga u dhexeeya SMT & DIP

(1) SMT guud ahaan waxay ku dhajisaa qaybaha dusha sare ee dusha sare leh ee aan lahayn sunta rasaasta. Jinka Alxanku wuxuu ubaahan yahay in lagu daabaco sabuuradda, ka dibna lagu dhajiyo jibbaar jibbaar ah, ka dibna aaladda ayaa lagu hagaajiyaa dib u sii dajinta; uma baahna in lagu keydiyo wax u dhigma iyada oo loo marayo godadka sadarka qayb ka mid ah, iyo cabirka cabbirka ee teknolojiyadda kor u qaadista dusha sare ayaa aad uga yar tiknoolajiyadda gelinta daloolka.

(2) DIP soldering waa aalad xirmo toos ah loo soo baakadeeyay, taas oo lagu hagaajinayo iyadoo la ruxruxaayo mowjad ama alaab gacmeed.
