1. Fafaza i-flux engahlanzekile ebhodini lesifunda
Ifakwe ezingxenyeni eziqediwe zebhodi lesifunda, izoshumekwa ku-jig, kusukela emshinini emnyango wedivaysi yokuhlanganisa kuya ku-angle ethile yokuthambekela kanye nesivinini sokudluliselaumshini we-wave soldering, bese ngokuqhubeka nokusebenza kwe-claw clamping yeketango, indlela inzwa yenzwa, umlomo wombhobho ubuye ubuye naphambili eduze nendawo yokuqala yesifutho se-jig uniform, ukuze indawo yephedi eveziwe yebhodi lesekethe, iphedi phezu kwembobo nezikhonkwane zengxenye. ubuso obumbozwe ngokulinganayo ngongqimba oluncane lwe-flux.
2. Ukushisa ngaphambili ibhodi le-PCB
Endaweni yokushisa, izingxenye ze-PCB zebhodi le-solder zishiswa ekushiseni okumanzi, ngesikhathi esifanayo, ngenxa yokwanda kwezinga lokushisa lengxenye, ukugwema ukucwiliswa ku-solder encibilikisiwe lapho ibhekene nokushaqeka okukhulu okushisayo.Isiteji sokushisa, izinga lokushisa le-PCB ebusweni kufanele libe phakathi kuka-75 ~ 110 ℃ kufanelekile.
1) Indima yokushisa kuqala.
① i-solvent ku-flux iyahwamuka, enciphisa ukukhiqizwa kwegesi lapho i-soldering.
② i-flux ku-rosin kanye ne-ejenti esebenzayo yaqala ukubola futhi isebenze, ingasusa amaphedi ebhodi aphrintiwe, amathiphu engxenye nezikhonkwane ebusweni befilimu ye-oxide nezinye izinto ezingcolisayo, kuyilapho idlala indima ekuvikeleni indawo yensimbi ukuvimbela ukwenzeka kokuphezulu. -i-temperature re-oxidation.
③ ukuze ibhodi PCB kanye izingxenye preheated ngokugcwele, ukugwema Welding lapho ukuphakama okubukhali lokushisa elakhiwe ezishisayo ukucindezeleka umonakalo PCB ibhodi kanye izingxenye.
2) umshini wokugcwalisa i-wave ngezindlela ezijwayelekile zokushisa
① Ukushisa kwe-convection komoya
② Ukushisisa i-infrared heater
③ Ukushisa ngenhlanganisela yomoya oshisayo nemisebe
3. ukwenza isinxephezelo sezinga lokushisa ngokufakwa kwe-wave soldering.
Faka isigaba sokunxeshezelwa kwezinga lokushisa, ngemva kokunxeshezelwa kwebhodi le-PCB ekusongesheni kwamagagasi ukuze unciphise ukushaqeka okushisayo.
4. ebhodini lesifunda phezu kwegagasi lokuqala
Igagasi lokuqala liyimfucumfucu emincane yezinga lokugeleza "kwe-turbulence", ikhambi linokungena okuhle komthunzi wezingxenye zokushisela.Ngasikhathi sinye, amandla e-jet akhuphukayo akhuphukayo enza igesi egelezayo ikhishwe ngokushelela, kunciphisa kakhulu ukuvuza kwe-solder kanye nokukhubazeka kokugcwalisa okuqondile.
5. Igagasi lesibili lebhodi lesifunda
Igagasi lesibili i-solder “ebushelelezi” igeleza kancane, ingasusa ngempumelelo i-solder eyeqile kutheminali, ukuze yonke indawo ye-solder imanzise kahle, futhi ingaba igagasi lokuqala elibangelwa ukudonsa ichopho kanye nebhuloho ukuze lilungise ngokugcwele.
6. ibhodi lesifunda lingene esigabeni sokupholisa
Uhlelo lokupholisa lenza izinga lokushisa le-PCB lehle kakhulu lingathuthukisa kakhulu ukukhiqizwa kwe-eutectic ye-lead-free solder lapho ukukhiqizwa kwamabhamuza omoya kanye nezinkinga zokukhumula ithreyi ye-solder.
I-Zhejiang NeoDen Technology Co., Ltd. ibikhiqiza futhi ithumela kwamanye amazwe amancane ahlukahlukene ukukhetha nokubeka imishinikusukela ngo-2010. Sisebenzisa i-R&D yethu ecebile enesipiliyoni, ukukhiqizwa okuqeqeshwe kahle, i-NeoDen izuza idumela elihle kumakhasimende omhlaba wonke.
