Cov txheej txheem tseem ceeb ntawmreflow soldering khoomyog cov cua kub hloov, saw ceev tswj thiab cua ceev thiab huab cua ntim tswj.
1. Kev tswj cov cua sov hloov hauvsoldering qhov cub.
Tam sim no, ntau yam khoom siv cov tshuab tsis muaj hlau lead, yog li covreflow soldering tshuabsiv tam sim no mas yog cua kubreflow soldering.Nyob rau hauv cov txheej txheem ntawm cov hlau lead-dawb soldering, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau qhov kub hloov pauv thiab kev ua haujlwm kub hloov pauv.Tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob loj, yog tias muaj kev hloov pauv hluav taws xob txaus thiab tsis tuaj yeem tau txais, cov cua sov yuav qis dua li cov khoom siv hluav taws xob me me, uas ua rau qhov kub thiab txias sib txawv..Cov cua ntws hom ntawm lub reflow qhov cub lub cev ncaj qha cuam tshuam rau lub tshav kub pauv ceev.Ob txoj kev hloov pauv cua kub rau reflow soldering yog: micro-cim cua kub hloov txoj kev, thiab lwm yam yog hu ua me me-kub kub cua hloov txoj kev.
2. Tswj cov saw ceev ntawmreflow soldering.
Kev tswj cov saw ceev ntawm cov khoom siv reflow soldering yuav cuam tshuam rau qhov sib txawv ntawm qhov kub thiab txias ntawm lub rooj tsavxwm.Feem ntau hais lus, txo cov saw nrawm yuav muab lub cuab yeej nrog lub peev xwm kub ntau lub sijhawm kom sov, yog li txo qhov kub ntawm qhov sib txawv.Tab sis tom qab tag nrho, qhov kev teeb tsa ntawm lub cub tawg kub yog nyob ntawm qhov yuav tsum tau ntawm cov tshuaj txhuam hniav, yog li nws tsis muaj tseeb los txo cov saw nrawm yam tsis muaj kev txwv hauv kev tsim khoom tiag tiag.
3. Tswj huab cua ceev thiab huab cua ntim ntawm reflow soldering khoom.
Khaws lwm yam xwm txheej hauv lubreflow qhov cubtsis hloov pauv thiab tsuas yog txo cov kiv cua ceev hauv qhov cub reflow los ntawm 30%, qhov kub ntawm lub rooj tsavxwm Circuit Court yuav poob li ntawm 10 degrees.Nws tuaj yeem pom tias kev tswj hwm huab cua ceev thiab huab cua ntim yog qhov tseem ceeb rau kev tswj qhov kub thiab txias.
Txhawm rau kom paub txog kev tswj cov cua ceev thiab huab cua ntim, ob lub ntsiab lus yuav tsum tau them sai sai rau:
ib.Qhov ceev ntawm lub kiv cua yuav tsum tau tswj los ntawm kev hloov pauv zaus kom txo tau qhov cuam tshuam ntawm qhov hloov pauv ntawm qhov hluav taws xob ntawm nws;
b.Txo qhov tso pa tawm ntawm cov khoom siv, vim tias qhov nruab nrab ntawm cov pa tawm hauv nruab nrab feem ntau tsis ruaj khov, uas yooj yim cuam tshuam rau cov cua kub hauv qhov cub.
