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 wokubeka kumgca wemveliso we-SMT sisithando somlilo esiphilisayo, umsebenzi wawo oyintloko kukunyibilikisa iglue yokubeka, ukwenzela ukuba amacandelo aphezu komhlaba kunye nebhodi ye-PCB zidibaniswe 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. Umsebenzi ophambili 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.
