Iifektri ezininzi ze-elektroniki zicinga ukuba ukuthenga umatshini omkhulu wokuphinda uthengisele unokuhlangabezana neemfuno zokusebenza ngokubanzi, kodwa kudla ngokubiza imali eninzi kwaye uncama indawo ehleliyo.I-8 ukuya kwi-10 yezone reflow kunye nezantya zebhanti ezikhawulezayo zinokuba sisisombululo esona sisombululo kwindawo ephezulu yokuvelisa umthamo, kodwa amava ethu abonise ukuba imodeli encinci, ilula, ifikeleleke ngakumbi kwi-4 ukuya kwi-6 yezowuni yeyona nto yethu ilungileyo Umthengisi ophezulu kwaye wenza umsebenzi ogqwesileyo. yokuphatha pick kunye nendawo throughput, idibana solder paste abavelisi 'reflow Specifications, kwaye ihambisa ethembekileyo, ukusebenza premium soldering.Kodwa unokuqiniseka njani?Zingaphi iimveliso ezinokusingatha inkqubo ye-4-zone, 5-zone okanye 6-zone reflow process?Olunye ubalo olulula olusekwe kwidatha enikezwe yi-solder paste kunye nababoneleli bezixhobo baya kukunika ireferensi elungileyo kakhulu.
Ixesha lokufudumeza i-solder paste
Into yokuqala ekufuneka uyithathele ingqalelo luyilo olucetyisiweyo lomenzi wakho wokuncamathisela kuqulunqo lwencama oza kuyisebenzisa.Abavelisi be-Solder paste ngokuqhelekileyo babonelela ngokufanelekileyo ngokufanelekileyo amaxesha efestile (ngokwexesha lokufudumeza lilonke) kwiinqanaba ezahlukeneyo zeprofayili yokuphinda-phinda - i-120 ukuya kwi-240 imizuzwana ye-preheat kunye nexesha lokufunxa, kunye ne-60 ukuya kwi-120 imizuzwana ye-reflow ixesha / ixesha elingaphezu kobume be-liquid.Sifumene i-avareji yobushushu bexesha eliphakathi kwemizuzu emi-4 ukuya kwe-4½ (240-270 imizuzwana) ukuba luqikelelo olulungileyo, olunolondolozo.Ngolu balo olulula, sincoma ukuba ungayihoyi ukupholisa kweeprofayili ezidibeneyo.Ukupholisa kubalulekile, kodwa ngesiqhelo akuyi kuchaphazela umgangatho wokuthengisela ngaphandle kokuba i-PCB ipholile ngokukhawuleza.
Ubude be-oveni yokufudumeza kwakhona
Ingqwalasela elandelayo lixesha elipheleleyo lokufudumeza ukufudumeza, phantse bonke abavelisi be-reflow baya kubonelela ubude bokufudumala kwe-reflow, ngamanye amaxesha kuthiwa ubude betonela yokufudumeza, kwiinkcukacha zabo.Kulo zibalo ezilula, sigxininisa kuphela kwindawo yokubuyisela kwakhona apho ukufudumala kwenzeka.
isantya ibhanti
Kugatya ngalunye olisebenzisayo, yahlula ubude bobushushu (kwii-intshi) ngenani elipheleleyo elicetyiswayo lobushushu (kwimizuzwana).Emva koko phinda-phinda nge 60 imizuzwana ukufumana isantya sebhanti kwii-intshizi ngomzuzu.Umzekelo, ukuba ixesha lakho lobushushu be-solder yimizuzwana engama-240-270 kwaye ucinga ngokuphinda kuqukunjelwe indawo emi-6 kunye netonela eyi-80¾ ye-intshi, yahlula i-intshi ezingama-80.7 ngama-240 kunye nama-270 imizuzwana.Iphindaphindwe ngamasekhondi angama-60, oku kukuxelela ukuba kufuneka usete isantya sebhanti lokubuyela kwakhona phakathi kwe-intshi ze-17.9 ngomzuzu kunye ne-20.2 intshi ngomzuzu.Emva kokuba unqume isantya sebhanti oyifunayo kwi-reflow ocinga ngayo, kufuneka unqume inani eliphezulu leebhodi ngomzuzu ezinokucutshungulwa kwi-reflow nganye.
Elona nani liphezulu leepleyiti zokubuyisela ngomzuzu
Ukucinga ukuba ngomthamo omkhulu kufuneka ulayishe iibhodi ekupheleni-kwisiphelo kwi-conveyor ye-oven reflow, kulula ukubala isivuno esiphezulu.Ngokomzekelo, ukuba ibhodi yakho i-7 intshi ubude kunye nesantya sebhanti ye-oven ye-6-zone reflow range ukusuka kwi-17.9 intshi ukuya kwi-intshi ye-20.2 ngomzuzu, ubuninzi be-output yaloo reflow yi-2.6 ukuya kwiibhodi ze-2.9 ngomzuzu.Oko kukuthi, iibhodi zeesekethe eziphezulu nezisezantsi ziya kuthengiswa malunga nemizuzwana engama-20.
Yeyiphi i-Oveni yokuPhumeza eyeyona ilungileyo kwiiMfuno zakho
Ukongezelela kwezi nkalo zingasentla, kukho ezinye izinto ezininzi ekufuneka ziqwalaselwe.Umzekelo, imveliso enamacala amabini inokufuna ukuqukuqela kwakhona kumacala omabini ecandelo elifanayo, kunye nokusebenza kwendibano yezandla kunokuchaphazela ukuba kungakanani na amandla okubuyisela okufunekayo ngokwenene.Ukuba indibano ye-SMT yakho ikhawuleza kakhulu, kodwa ezinye iinkqubo ziyasikela umda kwi-output yomzi-mveliso wakho, ngoko ke olona hlaziyo lukhulu lwehlabathi alulunganga kangako kuwe.Enye into ekufuneka iqwalaselwe kukutshintsha kwexesha ukusuka kwenye imveliso ukuya kwenye.Kuthatha ixesha elingakanani ukuba iqondo lobushushu liphinde lizinze xa utshintsha ukusuka kuqwalaselo olunye ukuya kolunye?Kukho izinto ezininzi ezahlukeneyo zokuqwalaselwa.
Umzi-mveliso waseChengyuan ugxile ekuphindeni kufakwe i-solder, i-wave soldering, kunye noomatshini bokugquma iminyaka engaphezu kweshumi.Wamkelekile ukuba uqhagamshelane neenjineli zaseChengyuan ukuze ukhethe eyona ifanelekileyo i-solder ye-reflow yakho.
