Uqhubekeko lwe-SMTluluhlu lwenkqubo yeteknoloji yokulungiswa ngokwesiseko sePCB.Ineenzuzo zokuchaneka okuphezulu kunye nesantya esikhawulezayo, ngoko yamkelwe ngabavelisi abaninzi be-elektroniki.Inkqubo yokwenziwa kwetshiphu ye-SMT ibandakanya ikakhulu isikrini sesilika okanye ukukhupha iglu, ukunyuswa okanye ukunyanga, ukuphinda kufakwe i-solder, ukucocwa, ukuvavanywa, ukuphinda kusetyenzwe, njl.
1.Ushicilelo lwesikrini
Izixhobo zangaphambili ezikumgca wemveliso we-SMT ngumatshini wokuprinta kwesikrini, umsebenzi wawo oyintloko kukuprinta i-solder paste okanye i-patch glue kwiipads ze-PCB ukulungiselela ukuthengiswa kwamacandelo.
2. Ukuhambisa
Izixhobo ezibekwe ekupheleni komgca wemveliso ye-SMT okanye emva komatshini wokuhlola i-glue dispenser.Umsebenzi wayo ophambili kukulahla iglu kwindawo emiselweyo yePCB, kwaye injongo kukulungisa amacandelo kwiPCB.
3. Ukubekwa
Izixhobo ezisemva komatshini wokuprinta isikrini sesilika kumgca wokuvelisa we-SMT ngumatshini wokubeka, osetyenziselwa ukunyuswa ngokuchanekileyo amacandelo okunyusa umgangatho kwindawo emiselweyo kwi-PCB.
4. Ukunyanga
Izixhobo ezisemva komatshini wokubekwa kumgca wemveliso we-SMT sisithando somlilo esiphilisayo, umsebenzi wawo ophambili kukunyibilikisa iglue yokubeka, ukwenzela ukuba amacandelo aphezu komhlaba kunye nebhodi yePCB zidityaniswe ngokuqinileyo kunye.
5. Reflow soldering
Izixhobo ezisemva komatshini wokubeka kumgca wemveliso we-SMT yi-oven yokuphinda iqhutyelwe, umsebenzi wayo oyintloko kukunyibilikisa i-solder paste ukwenzela ukuba i-surface mount components kunye nebhodi ye-PCB zidibaniswe ngokuqinileyo kunye.
6. Ukufunyanwa
Ukuqinisekisa ukuba umgangatho we-soldering kunye nomgangatho wendibano yebhodi yePCB edityanisiweyo iyahlangabezana neemfuno zefektri, iiglasi zokukhulisa, iimicroscopes, abavavanyi be-in-circuit (ICT), abavavanyi be-flying probe, ukuhlolwa okuzenzekelayo (AOI), iinkqubo zokuhlola i-X-RAY. kunye nezinye izixhobo ziyafuneka.Owona msebenzi uphambili kukubona ukuba ngaba ibhodi yePCB ineziphene ezifana nesoldering ebonakalayo, i-solder elahlekileyo, kunye neentanda.
7. Ukucoca
Kusenokubakho iintsalela ze-soldering eziyingozi kumzimba womntu njengokuguquguquka kwibhodi yePCB edityanisiweyo, ekufuneka icocwe ngomatshini wokucoca.
