Telecom taleefanka gacanta ee loo yaqaan 'ColeCone Countfire'
Kani waa mashruuc PCB golud ah oo loogu talagalay magaca gacanta ee loo yaqaan 'Cellphone'. Elektiroonigga macaamiisha, ka soosaarka maqalka ah ee lagu raaxeysto, ciyaarista ama xitaa xaqiiqda dhabta ah, dhammaantood way helayaan oo iskuxiran. Adduunyada dijitaalka ah ee aan ku nool nahay waxay u baahan tahay isku xirnaansho sare iyo koronto hormaris ah, xitaa shirkada elektaroonigga ah ee gawaarida, annaga, annaga oo ah Anke, oo aan u dhiibno adeegyo tayo sare leh oo ku saabsan injineerinka, naqshadeynta iyo qaabeynta.

Geedi socodka Golaha SMT
1. Goobta (Daaweynta)
Doorkeedu waa inuu dhalaalo koollada balastarka si ay dusha sare u kaxeeyaan dusha sare ee dusha sare iyo gudiga PCB-da si adag loo wada xidhan yahay.
Qalabka loo isticmaalo waa foornada la daaweeyo, oo ku yaal mashiinka meelaynta ee khadka Smt.
2. Dib-u-iibinta
Doorkeedu waa inuu dhalaalo koollada gacanta, si dusha sare looga baxo dusha sare ee dusha sare iyo guddiga PCB ay si adag isugu xiraan. Qalabka loo isticmaalo wuxuu ahaa foornada wax lagu guro, oo ku yaal dabayaaqadaha gadaashiisa.
Waxunol on khadka wax soo saarka SMT.
3. Nadiifinta Shirka SMT
Waxa ay tahay in meesha laga saaro habayadaha keligood sida UX
PCB-ga la soo ururiyey wuxuu waxyeelo u leeyahay jirka bini aadamka. Qalabka loo isticmaalo waa mashiinka dharka lagu dhaqo, goobta ayaa laga yaabaa inay tahay
Lama hagaajin, waxay noqon kartaa khadka tooska ah ama khadka tooska ah.
4. Baadhitaanka Golaha SMT
Shaqadiisa waa in la hubiyo tayada alxanka iyo tayada golaha
Guddiga PCB ee la soo ururiyey.
Qalabka loo isticmaalo waxaa ka mid ah isweydaarsiga dhalada weyn, mikroskoope, tijaabiyaha-isweydaarsiga (ICT), tijaabada irbadda, baaritaanka otomatiga otomatiga ah (AOI), nidaamka kormeerka raajada, iwm.
5. Dib-u-habeynta Golaha SMT
Doorkeedu waa in dib loo isticmaalo guddiga PCB ee fashilmay
Khalad. Qalabka loo adeegsaday waa iibinta birta, rugta dib-u-qabashada, iwm.
meel kasta oo ku yaal khadka wax soo saarka. Sidaad ogtahay, waxaa jira arrimo yaryar inta lagu gudajiro waxsoosaarka, sidaa darteed kulanka gacanta ayaa ah habka ugu fiican.
6. Baakadaha Golaha SMT
PCBMAY waxay siisaa kulan, baakadaha caadiga ah, calaamadinta, soosaarka qolka nadiifinta, maareynta jeermiga iyo xalka kale ee lagu bixiyo xalka caadada ah ee baahiyaha shirkaddaada.
Adigoo adeegsanaya otomaatig ah, xirmo oo xaqiijiya badeecadaheena, waxaan ku siin karnaa macaamiisheena si aad u badan oo wax soo saar badan oo wax lagu kalsoonaan karo oo hufan.
Bixiyaha adeegga wax soo saarka ee elektaroonigga ah ee baabuurta, waxaan daboolnaa codsiyo badan:
> Wax soo saarka kamaradaha baabuurta
> Qulqulka & huurada dareemayaasha
> Nalalka hore
> Iftiinka caqliga leh
> Moduleles korantada
> Xakameeyayaasha albaabka & gacanta albaabka
> Moodooyinka xakameynta jirka
> Maamulka Tamarta
Saddexaad, qiimayaashu way ku kala duwan yihiin kakanaanta iyo cufnaanta.
PCB waxay noqon doontaa qiime ka duwan xitaa haddii qalabka iyo howsha ay isku mid yihiin, laakiin ay ku jiraan kakanaanta iyo cufnaanta kala duwan. Tusaale ahaan, haddii ay jiraan 1000 god oo labada god ah oo dhexroor ah, dhexroor dhexroor ah oo ka mid ah gudida boodhka ayaa ka weyn 0.6mm iyo dhexroorka godka ee guddiga kale ay ka yar tahay 0.6mm, oo sameyn doonta kharashyo qoditaan oo kala duwan. Haddii laba looxyo wareeg ah ay isku mid yihiin codsiyada kale, laakiin ballaca xariiqda ayaa sidoo kale ka duwan waxay sidoo kale keentaa kharashyo kaladuwan, sida ballaca ee guddiga ayaa ka weyn 0.2mm, halka midka kale uu ka yar yahay 0.2mm. Sababtoo ah ballaca looxyo ka yar 0.2mm waxay leeyihiin qiime cilladaysan, taas oo macnaheedu yahay in qiimaha wax soo saarka uu ka sarreeyo kan caadiga ah.
Tan afraad, qiimayaashu way ku kala duwan yihiin shuruudaha macaamiisha oo kala duwan.
Shuruudaha macaamiisha ayaa si toos ah u saameyn doona heerka aan cillad lahayn ee wax soo saarka. Sida hal gole oo ay ku qoran yihiin IPC-A-600E Fasalka 11aad waxay u baahan tahay 38% Pass-ka, intaad u baahan tahay heerka fasalka 90%, taasoo keenta kharashyo kaladuwan oo ah warshadda oo ay ugu dambeyntii horseedaan isbeddelada qiimaha badeecada.
