Alaabta
Taleefoonka gacanta ee isgaadhsiinta guud ee ururinta wax soo saarka
Kani waa mashruuc isku-xidhka PCB oo loogu talagalay baardka weyn ee taleefanka gacanta.Elektrooniga macaamiisha, laga bilaabo alaabada maqalka ilaa kuwa la xidhi karo, ciyaaraha ama xitaa xaqiiqada dhabta ah, dhamaantood way sii kordhayaan isku xidhka.Dunida dhijitaalka ah ee aan ku noolnahay waxay u baahan tahay isku xirnaan heer sare ah iyo qalab elektaroonik ah oo horumarsan iyo awoodaha, xitaa kuwa ugu fudud ee alaabooyinka, awood siinta isticmaaleyaasha adduunka oo dhan.Sida shirkad elektaroonig ah oo baabuurta iyo soo saaraha PCBA-ga, annaga, ANKE, ayaa bixiya adeegyo tayo sare leh injineernimada, naqshadeynta iyo prototyping.

Habka Golaha SMT
1. Goobta (daaweynta)
Doorkeedu waa inay dhalaaliso xabagta balastarka ah si qaybaha korka ee korka iyo guddiga PCB ay si adag isugu xidhan yihiin.
Qalabka la isticmaalo waa foornada wax lagu daweeyo, oo ku taal gadaasha mashiinka meelaynta ee khadka SMT.
2. Dib u iibinta
Doorkeedu waa inay dhalaaliso koollada alxanka, si qaybaha dusha sare ee korka iyo guddiga PCB ay si adag isugu xidhan yihiin.Qalabka la isticmaalay waxa uu ahaa foorno dib loo rogo, oo ku taal suufka gadaashiisa.
Ku dheji khadka wax soo saarka ee SMT.
3. Nadiifinta golaha SMT
Waxa ay qabato ayaa ah in meesha laga saaro haraaga alxanka sida ux
PCB-ga la soo ururiyay waxay waxyeelo u gaystaan jidhka bini'aadamka.Qalabka loo isticmaalo waa mashiinka dharka lagu dhaqdo, meesha laga yaabo inay noqoto
Ma go'an, waxay noqon kartaa onlayn ama offline.
4. Kormeerka shirarka SMT
Shaqadeedu waa inay hubiso tayada alxanka iyo tayada isu imaatinka
Guddiga PCB-ga la shiray.
Qalabka la isticmaalay waxaa ka mid ah muraayadaha weyneeya, mikroskoob, tijaabiyaha wareegga gudaha (ICT), tijaabiyaha irbadda, kormeerka indhaha ee tooska ah (AOI), nidaamka kormeerka X-RAY, tijaabiyaha shaqada, iwm.
5. Dib-u-shaqaynta golaha SMT
Doorkeedu waa inuu dib u shaqeeyo guddiga PCB-ga ee fashilmay
KhaladQalabka loo isticmaalo waa birta alxanka, xarunta dib-u-shaqaynta, iwm.
meel kasta oo khadka wax soo saarka.Sida aad ogtahay, waxaa jira arrimo yar yar inta lagu jiro wax-soo-saarka, markaa dib-u-shaqaynta gacanta ayaa ah habka ugu fiican.
6. Baakadaha shirka SMT
PCBMay waxay bixisaa isu imaatinka, baakadaha caadiga ah, calaamadaynta, wax soo saarka qolka nadiifka ah, maaraynta jeermiska iyo xalalka kale si loo helo xal caada ah oo dhamaystiran oo loogu talagalay baahida shirkaddaada.
Adigoo isticmaalaya otomaatiga si aad isugu ururiso, baakadayso oo u ansixiso badeecadayada, waxaan ku siin karnaa macaamiisheena hannaan wax soo saar la isku halayn karo oo hufan.
Bixiyaha adeegga wax soo saarka elektaroonigga ah ee Automotive, waxaanu daboolnaa codsiyo badan:
> Alaabta kamarada baabuurta
> Heerkulka & dareemayaasha qoyaanka
> Iftiinka hore
> Iftiin wanaagsan
> Qalabka korontada
> Xakamaynta albaabka & gacan-qabsiga albaabka
> Qaybaha xakamaynta jidhka
> Maareynta tamarta
Saddexaad, qiimayaashu way kala duwan yihiin sababtoo ah kakanaanta iyo cufnaanta.
PCB waxay noqon doontaa kharash kala duwan xitaa haddii agabka iyo habsocodka ay isku mid yihiin, laakiin leh kakanaanta iyo cufnaanta kala duwan.Tusaale ahaan, haddii ay jiraan 1000 godad oo ku yaal labada loox ee wareegga, dhexroorka daloolka mid ka mid ah wuxuu ka weyn yahay 0.6mm iyo dhexroorka daloolka guddiga kale wuxuu ka yar yahay 0.6mm, taas oo samayn doonta kharashyo kala duwan oo qodista.Haddii laba loox oo wareeg ah ay isku mid yihiin codsiyada kale, laakiin ballaciisu waa ka duwan yahay sidoo kale wuxuu keenaa kharashyo kala duwan, sida hal ballaciisu waa ka weyn yahay 0.2mm, halka kan kale ee leh uu ka yar yahay 0.2mm.Sababtoo ah ballaca looxyada wax ka yar 0.2mm ayaa leh heerka cilladaysan, taas oo macnaheedu yahay qiimaha wax soo saarku wuu ka sarreeyaa midka caadiga ah.
Afar, qiimayaashu way kala duwan yihiin sababtoo ah shuruudaha macaamiisha kala duwan.
Shuruudaha macaamiisha ayaa si toos ah u saameyn doona heerka aan cillad lahayn ee wax soo saarka.Sida hal guddi oo waafaqsan IPC-A-600E class1 waxay u baahan tahay 98% heerka gudbinta, halka heshisyada fasalka 3 ay u baahan yihiin oo kaliya inay haystaan 90% heerka baasas, taasoo keenta kharashyo kala duwan warshadda oo ugu dambeyntii horseedaysa isbeddel ku yimaada qiimaha alaabta.
