Izilumkiso zokusetyenziswa kwe-oven ye-SMT reflow.

I-oven ye-smt reflow sisixhobo se-smt-back-end, umsebenzi ophambili kukunyibilikisa i-solder paste, kwaye emva koko uvumele izinto ze-elektroniki zidle i-tin, ukuze zilungiswe kwi-pcb pad,smt kwakhona izixhoboyenye yeendawo ezintathu eziphambili ze-smt, i-reflow soldering Iziphumo kunye neempembelelo zibaluleke kakhulu kumgangatho weemveliso eziveliswayo.

1. Ukumiselwa kwendawo yeqondo lokushisa akukwazi ukulungiswa ngaphandle kwesizathu.Iiparamitha zommandla wobushushu odweliswe apha ngasentla ngokusisiseko zimiselwe ngokweyona mpembelelo yonyango yokuba indawo yebhodi ye-welding pcb iphendula i-90% yendawo esebenzayo yestencil yokuhambisa kwi-welding eziko, kwaye izinga lokuthutha ibhanti yi-75cm± 10cm/S.ye.Xa kukho umahluko omkhulu kwindawo yebhodi ye-pcb esetyenzisiweyo, isantya sebhanti kufuneka silungiswe kakuhle ukuze sifezekise umphumo omuhle we-welding.Umgaqo-jikelele wohlengahlengiso kukuba: xa indawo yebhodi ye-pcb incinci, isantya sebhanti ye-mesh sihamba ngokukhawuleza;xa indawo yebhodi ye-pcb inkulu, isantya sebhanti ye-mesh sihamba kancinci, kwaye yonke into ixhomekeke ekufezekiseni umphumo omuhle we-welding;

2. Iiparamitha ze-PID zetafile yokulawula ubushushu aziyi kusekwa ngokungaqhelekanga;

3. I-inlet kunye ne-outlet yomatshini wokuphinda uphinde udibanise kufuneka uphephe umoya wendalo wangaphandle ovuthuzayo ngexesha lokusetyenziswa, okuya kuchaphazela ibhalansi yobushushu obuguqukayo kwisithando somlilo kunye nokuchaphazelaukuweldaumgangatho;

4. Xa uthumela i-workpiece ye-PCB kwi-port yokukhutshwa kwesithando somlilo, kuyimfuneko ukuphepha ingozi yokutshisa isandla somqhubi;Kukwafuneka ukuthintela ibhodi ye-PCB ukuba iqokelele kwi-port yokukhupha, ebangela ukuba ibhodi ye-PCB iwe okanye ibhodi ye-PCB ekuphumeni.Amandla e-solder aphantsi phantsi kweemeko eziphezulu zokushisa Amacandelo e-SMD awela ngenxa yokuwa okanye ukutyumza impembelelo;

5. Yenza umsebenzi omhle kugcino lwemihla ngemihla lweumatshini wokuweldaizixhobo: coca umphezulu weizixhoboyonke imihla ukuze ikhululeke ekungcoleni, nqakraza iqhosha le-refueling kanye ngeveki kwimowudi ye-refueling manual, kwaye ugcobe i-roller chain nge-oyile yokushisa ephezulu yokushisa (BIO-30);kwimveliso eqhubekayo, ngenyanga Hayi ngaphantsi kwe kabini: Jonga ukongeza ubushushu obuphezulu ioli yokuthambisa kwisithando somlilo kunye nevili ngalinye leshaft elijikelezayo;

6. Khangela ukuba ngaba ucingo oluphantsi lomatshini we-welding luxhunyiwe ngokuthembekileyo ngaphambi kokuqala umatshini yonke imihla;

7. Emva kokusombulula ingxaki, vula unikezelo lwamandla oluphambili lwesixhobo kwaye ujike iswitshi yokumisa kaxakeka emile okwekhowa ebomvu ngewotshi ukuze ubuyele kwisimo sokuqala sokusebenza.Xa umatshini ucinyiwe, i-PCB kunye nebhanti yentsimbi ehambisa intsimbi akufanele imiswe kwisithando somlilo esisekwimeko yokushisa ephezulu, kwaye ibhanti yokuhambisa kufuneka imiswe emva kokuba iqondo lokushisa kumatshini lihlile.
