- Nyob rau hauv tus txheej txheem ntawmreflowqhov cub, lub Cheebtsam tsis ncaj qha impregnated nyob rau hauv lub molten solder, yog li ntawd lub thermal shock rau lub Cheebtsam yog me me (vim yog cov sib txawv cua sov txoj kev, thermal stress rau lub Cheebtsam yuav kuj loj nyob rau hauv tej rooj plaub).
- Muaj peev xwm tswj tau tus nqi ntawm cov khoom siv nyob rau hauv cov txheej txheem ua, txo cov vuam tsis xws li vuam virtual, choj, yog li qhov vuam zoo yog qhov zoo, qhov sib xws ntawm cov vuam sib txuas yog qhov zoo, muaj kev ntseeg siab.
- Yog tias qhov tseeb qhov chaw ntawm cov txheej txheem ua haujlwm ntawm PCB solder casting thiab muab qhov chaw ntawm cov khoom muaj qhov sib txawv, hauv cov txheej txheem ntawmreflow solderingtshuab, thaum tag nrho cov khoom ntawm cov vuam kawg, tus pin thiab cov khoom siv sib txuas ua ke nyob rau tib lub sijhawm, vim qhov cuam tshuam ntawm qhov nro ntawm cov molten solder, tsim cov nyhuv orientation, txiav kho qhov sib txawv, cov khoom rov qab mus rau kwv yees qhov chaw nyob. .
- SMT Reflowqhov cubyog ib qho kev lag luam solder paste uas ua kom muaj qhov tseeb thiab feem ntau tsis sib xyaw nrog impurities.
- Cov cua kub hauv zos tuaj yeem siv tau, yog li cov txheej txheem vuam sib txawv tuaj yeem siv rau vuam ntawm tib lub substrate.
- Cov txheej txheem yog yooj yim thiab kev ua haujlwm ntawm kev kho yog tsawg heev.
