Yuav ua li cas optimize qhov reflow profile?

Raws li kev pom zoo los ntawm lub koom haum IPC, cov generic Pb-dawbsolder reflowprofile yog qhia hauv qab no.GREEN cheeb tsam yog qhov kev lees paub rau tag nrho cov txheej txheem reflow.Puas yog nws txhais tau tias txhua qhov chaw hauv cheeb tsam GREEN no yuav tsum haum rau koj daim ntawv thov rov ua dua tshiab?Cov lus teb yog NO!

Lub PCB thermal muaj peev xwm txawv raws li cov khoom siv, thickness, tooj liab hnyav thiab txawm tias cov duab ntawm lub rooj tsavxwm.Nws kuj tseem txawv heev thaum cov khoom siv nqus cov cua sov kom sov.Cov khoom loj tuaj yeem xav tau sijhawm ntau dua los ua kom sov dua li cov me me.Yog li, koj yuav tsum txheeb xyuas koj lub hom phiaj pawg thawj coj ua ntej tsim kom muaj qhov tshwj xeeb reflow profile.

1. Ua ib tug virtual reflow profile.

Lub virtual reflow profile yog raws li qhov kev xav ntawm kev sib tw, qhov kev pom zoo ntawm solder profile los ntawm cov chaw tsim tshuaj paus, qhov loj, thickness, cooper hnyav, txheej ntawm lub rooj tsavxwm thiab qhov loj, thiab qhov ntom ntawm cov khoom.

1. Reflow lub rooj tsavxwm thiab ntsuas lub sijhawm tiag tiag thermal profile ib txhij.
2. Txheeb xyuas qhov sib koom ua ke zoo, PCB thiab cov xwm txheej ntawm cov khoom.
3. Hlawv-hauv lub rooj tsavxwm kuaj nrog thermal shock thiab mechanical shock los xyuas lub rooj tsavxwm kev ntseeg tau.
4. Sib piv cov ntaub ntawv thermal hauv lub sijhawm nrog cov ntaub ntawv virtual.
5. Kho qhov teeb tsa parameter thiab sim ob peb zaug kom pom qhov txwv sab sauv thiab kab hauv qab ntawm lub sijhawm tiag tiag reflow profile.
6. Txuag optimized tsis raws li lub hom phiaj board lub reflow specification.
