Qhov cub reflow yog dab tsi?

Reflow qhov cubyog ib qho ntawm peb cov txheej txheem tseem ceeb hauv SMT mounting txheej txheem.Nws yog tsuas yog siv los solder lub Circuit Court board ntawm cov khoom uas tau mounted.Lub solder paste yog melted los ntawm cua sov kom lub thaj thaj thiab lub Circuit Court board solder pad yog fused ua ke.To taubreflow soldering tshuab, koj yuav tsum nkag siab txog cov txheej txheem SMT ua ntej.

Cov tshuaj txhuam hniav yog sib xyaw ntawm cov hlau tin hmoov, flux thiab lwm yam tshuaj, tab sis cov tin hauv nws muaj nyob ntawm nws tus kheej li cov hlaws me me.Thaum lub rooj tsavxwm PCB los ntawm ntau qhov chaw kub hauv lub qhov cub reflow, siab tshaj 217 degrees Celsius, cov hlaws me me tin tau yaj.Tom qab cov flux thiab lwm yam catalyzed, kom suav tsis tau cov khoom me me yaj ua ke, uas yog hais tias, ua kom cov khoom me me rov qab mus rau lub xeev cov dej ntws, cov txheej txheem no feem ntau hais tias yog reflux.Reflux txhais tau hais tias tin hmoov los ntawm cov khoom qub rov qab mus rau lub xeev ua kua, thiab tom qab ntawd los ntawm qhov chaw txias rov qab mus rau lub xeev khov dua.

txawvreflow soldering tshuabmuaj qhov zoo sib txawv, thiab cov txheej txheem kuj txawv.
Infrared reflow soldering: siab hluav taws xob conduction tshav kub efficiency, siab kub steepness, yooj yim los tswj qhov kub thiab txias nkhaus, PCB sab sauv thiab qis kub yog ib qho yooj yim los tswj thaum ob-sided vuam.Muaj cov nyhuv duab ntxoov ntxoo, qhov kub tsis sib xws, yooj yim ua rau cov khoom siv los yog PCB hauv zos hlawv tawm.
Cov cua kub reflow soldering: uniform convection conduction kub, zoo vuam zoo.Qhov kub gradient yog qhov nyuaj rau tswj.
Forced cua kub reflow vuam yog muab faib ua ob hom raws li nws muaj peev xwm ntau lawm:

Cov cuab yeej ntsuas kub: huab hwm coj ntau yog tsim rau kev tsim khoom loj ntawm PCB pawg thawj coj saib tso rau ntawm txoj siv taug kev, mus los ntawm ntau qhov chaw ntsuas kub nyob rau hauv kev txiav txim, thaj tsam kub tsawg dhau yuav muaj qhov tshwm sim kub dhia, tsis haum rau kev sib dhos siab. phaj vuam.Nws tseem loj heev thiab siv hluav taws xob ntau.
Qhov kub thiab txias me me desktop khoom: me me thiab nruab nrab-qhov loj me batch ntau lawm kev tshawb fawb thiab kev loj hlob nyob rau hauv ib qho chaw ruaj khov, qhov kub thiab txias raws li cov txheej txheem teeb tsa hloov nrog lub sijhawm, yooj yim rau kev khiav lag luam.Kev kho cov khoom tsis zoo ntawm qhov chaw (tshwj xeeb yog cov khoom loj) tsis haum rau kev tsim khoom loj.
