4. Kev nchuav thiab xau: Thaum lub caij nplooj zeeg lossis xau, kev tu thaj chaw tam sim ntawd yog qhov tseem ceeb los tiv thaiv kev kis kab mob ntxiv. Qhov no tej zaum yuav suav nrog kev siv cov khoom nqus dej xws li xuab zeb lossis av nplaum kom muaj cov txeej thiab ntxuav thaj chaw nrog cov kuab tshuaj uas tsim nyog lossis tshuaj ntxuav.
5. Kev cob qhia: Kev cob qhia thiab kev kawm tsim nyog yuav tsum tau muab rau cov neeg ua haujlwm uas tuav SMT nplaum. Qhov no yuav tsum suav nrog cov ntaub ntawv hais txog kev tuav, khaws cia, thiab pov tseg ntawm Adhesive thiab kev siv PPE kom raug thiab cov txheej txheem teb thaum muaj xwm txheej tshwm sim los yog nchuav.

Los ntawm kev ua raws li cov kev coj ua zoo tshaj plaws rau kev tuav, khaws cia, thiab pov tseg ntawm SMT nplaum, cov tuam ntxhab tuaj yeem ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm Adhesive thaum txo cov kev phom sij lossis kev cuam tshuam ib puag ncig. Nws yog ib qho tseem ceeb rau kev sab laj cov chaw tsim khoom cov lus qhia, cov kev cai hauv zos, thiab cov lus qhia rau cov lus pom zoo thiab cov kev xav tau tshwj xeeb.

SMT nplaum tau hloov kho cov khoom siv hluav taws xob los ntawm kev txhim kho cov khoom lag luam kev ntseeg siab thiab ua kom muaj kev tso npe ncaj qha. Qhov ntau ntawm cov kev xaiv nplaum nplaum, kev nce qib hauv cov txheej txheem xa tawm, thiab kev txiav txim siab ib puag ncig tau ua rau SMT nplaum yog qhov tseem ceeb hauv cov txheej txheem tsim khoom niaj hnub no. Raws li kev lag luam hloov zuj zus mus, cov tuam txhab lag luam yuav tsum nyob twj ywm tshiab nrog cov kev tsim kho tshiab thiab cov kev coj ua zoo tshaj plaws nrog rau SMT cov nplaum kom ua tau zoo tshaj plaws, tawm los, thiab tag nrho cov khoom zoo. Los ntawm kev siv lub zog ntawm SMT nplaum, cov tuam txhab lag luam tuaj yeem qhib qhov muaj peev xwm tshiab hauv kev tsim khoom siv hluav taws xob, ua rau kev txhim kho kev ua tau zoo thiab cov neeg siv khoom txaus siab.
