Cov yam cuam tshuam rau qhov zoo ntawm reflow soldering

Cov yam cuam tshuam rau qhov zoo ntawm reflow soldering yog raws li nram no

1. Kev cuam tshuam ntawm cov tshuaj txhuam hniav
Qhov zoo ntawm reflow soldering yog cuam tshuam los ntawm ntau yam.Qhov tseem ceeb tshaj plaws yog qhov kub thiab txias ntawm reflow rauv thiab qhov muaj pes tsawg leeg ntawm cov tshuaj muab tshuaj.Tam sim no qhov kev ua tau zoo tshaj plaws reflow vuam rauv tau tuaj yeem tswj thiab kho qhov ntsuas kub kom raug.Nyob rau hauv sib piv, nyob rau hauv tus qauv ntawm high density thiab miniaturization, solder paste luam ntawv tau dhau los ua tus yuam sij rau reflow soldering zoo.
Lub particle zoo ntawm cov tshuaj txhuam cov hmoov txhuas muaj feem cuam tshuam rau qhov vuam zoo ntawm cov khoom siv nqaim, thiab cov viscosity thiab muaj pes tsawg leeg ntawm cov tshuaj txhuam yuav tsum raug xaiv kom raug.Tsis tas li ntawd, cov tshuaj txhuam hniav feem ntau yog khaws cia hauv qhov txias txias, thiab lub hau npog tsuas yog qhib thaum qhov kub thiab txias rov qab los rau hauv chav tsev.Kev saib xyuas tshwj xeeb yuav tsum tau them nyiaj kom tsis txhob sib tov cov tshuaj txhuam nrog dej vapor vim qhov kub sib txawv.Yog tias tsim nyog, sib tov cov tshuaj txhuam hniav nrog lub tov khoom.

2. Kev cuam tshuam ntawm cov khoom siv vuam
Qee zaum, kev co ntawm txoj siv conveyor ntawm reflow vuam cov cuab yeej kuj yog ib qho ntawm feem cuam tshuam rau vuam zoo.

3. Kev cuam tshuam ntawm reflow vuam txheej txheem
Tom qab tshem tawm qhov tsis zoo ntawm cov txheej txheem luam ntawv luam tawm thiab SMT txheej txheem, cov txheej txheem rov ua dua nws tus kheej kuj tseem yuav ua rau muaj qhov txawv txav hauv qab no:
① Nyob rau hauv txias vuam, qhov reflow kub yog tsawg los yog lub sij hawm reflow cheeb tsam tsis txaus.
② Qhov kub thiab txias hauv thaj tsam preheating ntawm tin hlaws nce ceev heev (feem ntau, txoj kab nqes ntawm qhov kub nce qis dua 3 degrees ib ob).
③ Yog tias lub rooj tsav xwm Circuit Court lossis cov khoom cuam tshuam los ntawm cov dej noo, nws yooj yim ua rau tawg tawg thiab tsim cov tin tas li.
④ Feem ntau, qhov kub thiab txias hauv cheeb tsam cua txias poob sai heev (feem ntau, qhov kub thiab txias txoj kab nqes ntawm cov hlau lead vuam yog tsawg dua 4 degrees ib ob).
