1.Storage condition of solder paste
Solder paste yuav tsum tau siv rau SMT thaj ua haujlwm.Yog tias tsis siv tshuaj txhuam hniav tam sim ntawd, nws yuav tsum muab tso rau hauv ib puag ncig ntuj ntawm 5-10 degrees, thiab qhov kub yuav tsum tsis pub tsawg dua 0 degrees lossis siab dua 10 degrees.
2. Kev tu txhua hnub ntawm SMT tshuab
SMTxaiv thiab tso tshuab kom tswj tau raws sijhawm, txhim kho cov kev cai thiab cov cai ntawm cov khoom siv tshuaj xyuas qhov chaw.Yog hais tias muaj embrittlement ntawm cov tshuab thiab cov khoom siv, los yog kev puas tsuaj ntawm cov khoom, yuav muaj SMT sticking slanting, siab ntuav thiab ib tug series ntawm tej yam kev mob, heev cuam tshuam rau kev tsim thiab tsim.
3. Kev kho dua tshiab thiab teeb tsa cov txheej txheem tseem ceeb
Txhawm rau kom ntseeg tau qhov kev sib txuas zoo ntawm PCB pawg thawj coj saib, peb yuav tsum nco ntsoov ua tib zoo saib xyuasreflowqhov cubcov txheej txheem ua tau zoo.Feem ntau, qhov ntsuas kub yuav tsum tau kuaj ob zaug ib hnub.Tsuas yog los ntawm kev txhim kho qhov kub thiab txias tsis tu ncua tuaj yeem lav qhov zoo ntawm cov khoom tsim thiab ua tiav.
4.Lifting xeem txoj kev
Vim lub complex qauv thiab kev siv tshuab ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob tsis muaj kev puas tsuaj tau muab tso rau hauv cov kev xav tau siab heev.Cov txheej txheem tshuaj ntsuam xyuas, suav nrog kev tshuaj xyuas qhov muag, AOItshuab, ICT thiab ultrasonic kuaj, tau ntev tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm cov txheeb ze ntom ntom, kev ua haujlwm tau zoo thiab kev ua qauv zoo hauv FIELD ntawm SMT.X-ray nrhiav txoj kev yog qhov kev xaiv zoo tshaj plaws los txhim kho qhov kev tshawb pom zoo thiab kev tsim khoom zoo nyob rau tam sim no.Saum toj no yog SMT thaj ua haujlwm kom xyuam xim rau cov ntsiab lus tseem ceeb, koj puas paub cov no?
Yog tias koj xav tau cov khoom siv SMT ntau lawm, thov koj xav tiv tauj peb.
