Amacandelo omgca wemveliso we-SMT:

Umgca wemveliso we-SMT uquka amacandelo azimeleyo asebenza ngokuhambelanayo ukuqinisekisa inkqubo yokuvelisa egudileyo.La malungu abalulekileyo aquka:

1. Umatshini we-SMT: Undoqo weUmgca wemveliso we-SMTngumatshini onoxanduva lokubeka izinto ze-elektroniki kwi-PCB.Baziwa ngokuba ngoomatshini bokukhetha nendawo, aba matshini basebenzisa iingalo zerobhothi kunye nemilomo yokufunxa ukukhetha izinto kwi-fieder kwaye bazibeke ngokuchanekileyo kwi-PCB.

2. I-oven ye-reflow: Emva kokuhlanganisana, i-PCB idlula kwi-oven yokubuyisela apho i-solder paste esetyenziselwa ukubamba amacandelo adibeneyo ayanyibilika kwaye aqiniswe, enze ibhondi eqinile.I-oven reflow iqinisekisa ukuba i-solder joints yenziwe ngokuchanekileyo kwaye amacandelo afakwe ngokukhuselekileyo kwi-PCB.

3. Umshicileli we-solder paste: Usetyenziso oluchanekileyo lwe-solder paste lubalulekile kwinkqubo ye-SMT.Umshicileli we-solder paste usebenzisa i-stencil ukufaka i-solder paste kwi-PCB, iqinisekisa ulungelelwaniso oluchanekileyo kunye neepads.

4. Inkqubo yokuhlola: Ukuze kugcinwe imigangatho yomgangatho, yonke imveliso yokuvelisa ithatha inkqubo yokuhlola.Oomatshini bokuhlola okuzenzekelayo (AOI) bajonga iziphene ezifana nezinto ezingekhoyo okanye ezingalungelelaniswanga kakuhle, iziphene zokuthengisela, kunye neziphene zePCB.Iinkqubo zokuhlola i-X-reyi zikwasetyenziselwa ukubona iziphene ezifihlakeleyo, ezinje ngokungonelanga kwamalungu e-solder.
