Reflow ncu yog siv nyob rau hauv Surface Mount Technology (SMT) manufacturing lossis semiconductor ntim txheej txheem.Feem ntau, reflow ncu yog ib feem ntawm cov khoom siv hluav taws xob sib dhos, suav nrog cov tshuab luam ntawv thiab tso chaw.Lub tshuab luam ntawv luam tawm solder paste rau ntawm PCB, thiab lub tshuab muab cov khoom tso rau ntawm cov ntawv luam tawm.
Teeb tsa lub Reflow Solder Pot
Kev teeb tsa lub qhov cub reflow yuav tsum muaj kev paub txog cov tshuaj nplaum uas siv rau hauv kev sib dhos.Puas yog cov slurry xav tau nitrogen (tsawg oxygen) ib puag ncig thaum cua sov?Reflow specifications, nrog rau qhov kub siab tshaj plaws, lub sij hawm saum cov kua dej (TAL), thiab lwm yam?Thaum cov txheej txheem no paub txog, tus txheej txheem engineer tuaj yeem ua haujlwm los teeb tsa cov ntawv qhia reflow nrog lub hom phiaj ntawm kev ua tiav ib qho profile reflow.Daim ntawv qhia txog qhov cub reflow yog hais txog qhov kub ntawm qhov cub, nrog rau qhov kub thiab txias, convection rates, thiab gas flow rates.Lub reflow profile yog qhov kub thiab txias uas lub rooj tsavxwm "pom" thaum lub sij hawm reflow txheej txheem.Muaj ntau yam yuav tsum tau xav txog thaum tsim cov txheej txheem reflow.Lub Circuit Court board loj npaum li cas?Puas muaj tej yam me me ntawm lub rooj tsavxwm uas tuaj yeem raug puas los ntawm kev kub siab convection?Dab tsi yog qhov siab tshaj plaws tiv thaiv kub txwv?Puas muaj teeb meem nrog kev loj hlob sai?Qhov xav tau profile yog dab tsi?
Nta thiab Nta ntawm Reflow Cub
Ntau lub qhov cub reflow muaj cov ntawv qhia tsis siv neeg teeb tsa software uas tso cai rau lub reflow solder los tsim ib daim ntawv qhia pib raws li cov yam ntxwv ntawm pawg thawj coj saib thiab cov lus qhia tshwj xeeb.Txheeb xyuas reflow soldering los ntawm kev siv lub thermal recorder los yog trailing thermocouple hlau.Reflow setpoints tuaj yeem hloov kho nce / nqis raws li qhov tseeb thermal profile vs. solder paste specifications thiab board/component kub txwv.Yog tsis muaj daim ntawv qhia tsis siv neeg teeb tsa, engineers tuaj yeem siv lub neej ntawd reflow profile thiab kho daim ntawv qhia kom pom cov txheej txheem los ntawm kev tshuaj xyuas.
