I.Measures hloov nto nro thiab viscosity
Viscosity thiab nto nro yog qhov tseem ceeb ntawm cov khoom siv.Qhov zoo tshaj plaws solder yuav tsum muaj tsawg viscosity thiab nto nro thaum melting.Nto nro yog qhov xwm txheej ntawm cov khoom, tsis tuaj yeem tshem tawm, tab sis tuaj yeem hloov pauv.
1.Qhov kev ntsuas tseem ceeb los txo qhov nro thiab viscosity hauv PCBA soldering yog raws li hauv qab no.
Ua kom qhov kub thiab txias.Ua kom qhov kub thiab txias tuaj yeem ua rau kom qhov deb ntawm molecular nyob rau hauv lub molten solder thiab txo cov gravitational quab yuam ntawm molecules nyob rau hauv cov kua solder nyob rau saum npoo molecules.Yog li ntawd, nce qhov kub thiab txias tuaj yeem txo cov viscosity thiab qhov nro.
2. Qhov nro ntawm Sn yog siab, thiab qhov sib ntxiv ntawm Pb tuaj yeem txo qhov nro ntawm qhov chaw.Ua kom cov ntsiab lus ntawm cov hlau lead hauv Sn-Pb solder.Thaum cov ntsiab lus ntawm Pb nce mus txog 37%, qhov nro ntawm qhov chaw txo qis.
3. Ntxiv tus neeg sawv cev ua haujlwm.Qhov no tuaj yeem txo qhov nro ntawm lub solder, tab sis kuj yuav tshem tawm cov txheej txheej oxide ntawm lub solder.
Kev siv cov nitrogen tiv thaiv pcba vuam lossis lub tshuab nqus tsev vacuum tuaj yeem txo qhov kub thiab txias oxidation thiab txhim kho cov wettability.
II.lub luag hauj lwm ntawm qhov nro nyob rau hauv vuam
Nto nro thiab wetting quab yuam nyob rau hauv qhov opposite kev taw qhia, yog li ntawd lub nto nro yog ib yam ntawm cov yam uas tsis conducive rau wetting.
Sebreflowqhov cub, yoj solderingtshuablos yog phau ntawv soldering, nto nro rau kev tsim cov pob qij txha zoo yog qhov tsis zoo.Txawm li cas los xij, nyob rau hauv cov txheej txheem kev tso kawm SMT reflow soldering nto nro tuaj yeem siv dua.
Thaum cov tshuaj txhuam hniav mus txog qhov kub thiab txias, nyob rau hauv qhov kev txiav txim ntawm qhov sib npaug ntawm qhov nro, yuav ua rau nws tus kheej txoj hauj lwm (Self-Alignment), uas yog, thaum lub sij hawm qhov chaw ntawm qhov chaw muaj qhov sib txawv me me, nyob rau hauv qhov kev txiav txim ntawm qhov nro, cov tivthaiv tuaj yeem rub rov qab mus rau qhov kwv yees lub hom phiaj txoj haujlwm.
Yog li ntawd, qhov nro saum npoo ua rau cov txheej txheem rov ua kom tiav rau qhov kev xav tau qhov tseeb kuj xoob, kuj yooj yim kom paub qhov siab automation thiab kev kub ceev.
Nyob rau tib lub sijhawm kuj yog vim tias "rov ua dua" thiab "qhov chaw ntawm tus kheej" tus yam ntxwv, SMT rov ua cov txheej txheem rov ua dua cov khoom siv lub ncoo tsim, cov qauv txheej txheem thiab lwm yam tau thov nruj dua.
Yog tias qhov nro ntawm qhov sib npaug tsis sib npaug, txawm tias qhov kev tso kawm yog qhov tseeb heev, tom qab vuam kuj tseem yuav tshwm sim ntawm qhov chaw sib cais, sawv monument, bridging thiab lwm yam vuam tsis xws luag.
Thaum yoj yoj, vim qhov loj thiab qhov siab ntawm SMC / SMD tivthaiv lub cev nws tus kheej, los yog vim lub siab tivthaiv thaiv cov khoom luv luv thiab thaiv cov tin nthwv dej ntws los, thiab cov duab ntxoov ntxoo tshwm sim los ntawm qhov nro ntawm cov tin yoj. ntws, cov kua solder tsis tuaj yeem nkag mus rau hauv lub nraub qaum ntawm lub cev kom tsim tau qhov chaw thaiv qhov chaw, uas ua rau cov xau ntawm cov khoom siv.
Nta ntawmNeoDen IN 6 Reflow Soldering tshuab
NeoDen IN6 muab kev ua haujlwm zoo reflow soldering rau PCB manufacturers.
Lub rooj-sab saum toj tsim ntawm cov khoom ua rau nws ib tug zoo meej tov rau ntau lawm kab nrog ntau yam yuav tsum tau.Nws yog tsim los nrog automation nyob rau hauv uas pab cov neeg ua hauj lwm muab streamlined soldering.
Tus qauv tshiab tau dhau los ntawm qhov xav tau rau lub rhaub tubular, uas muab kev faib tawm txawm tias qhov kub thiab txiasthoob plaws lub qhov cub reflow.Los ntawm soldering PCBs nyob rau hauv txawm convection, tag nrho cov Cheebtsam yog rhuab nyob rau tib tus nqi.
Tus tsim siv lub aluminium alloy cua sov phaj uas ua rau kom lub zog-efficiency ntawm lub cev.Cov pa luam yeeb sab hauv lim dej txhim kho cov khoom lag luam kev ua tau zoo thiab txo cov khoom tsim tawm, thiab.
Cov ntaub ntawv ua haujlwm tau khaws cia hauv qhov cub, thiab ob qho tib si Celsius thiab Fahrenheit hom muaj rau cov neeg siv.Lub qhov cub siv qhov hluav taws xob 110/220V AC thiab muaj qhov hnyav tag nrho ntawm 57kg.
Lub NeoDen IN6 yog tsim nrog aluminium alloy cua sov chamber.
