Kev ceev faj rau SMT nti ntws vuam
Flow vuam yog txheej txheem tseem ceeb ntawm SMT nti ua. Ntau yam xwm txheej yuav raug ntsib hauv kev ua haujlwm. Yog tias tsis muaj txoj hauv kev kho kom raug thiab kev ntsuas tsim nyog, kev nyab xeeb thiab kev raug mob hnyav yuav tshwm sim.
Kev ceev faj rau SMT thaj ua thiab reflow vuam:
1. SMT nti reflow vuam rauv yuav tsum ncav cuag qhov kub thiab txias (lub teeb ntsuab yog nyob rau) ua ntej vuam tuaj yeem pib.
2. Thaum lub sij hawm vuam txheej txheem, qhov kub thiab txias hloov ntawm txhua cheeb tsam kub yog feem ntau pom, thiab qhov kev hloov ntau yam yog± 1 degree(raws li reflow vuam rauv).
3. Nyob rau hauv cov xwm txheej txawv txav, cov khoom siv yuav tsum raug kaw tam sim ntawd.
4. Qhov luaj li cas ntawm lub hauv paus phaj yuav tsum tsis txhob siab tshaj qhov dav ntawm txoj siv conveyor, txwv tsis pub nws yog nquag mus rau board jamming xwm txheej.
5. Ua ntej welding, kev tiv thaiv kev tiv thaiv (shielding) los yog tsis muaj reflow vuam yuav tsum raug coj mus rau cov khoom uas tsis tuaj yeem tiv taus qhov kub thiab txias raws li cov ntaub ntawv ntawm cov txheej txheem ua cov ntaub ntawv los yog cov lus qhia ntim khoom. Kev tuav vuam los yog tom qab vuam los ntawm vuam neeg hlau yuav tsum tau saws.
6. Thaum lub sij hawm welding, txoj siv conveyor yuav tsum nruj me ntsis tiv thaiv kev vibration, txwv tsis pub nws yuav ua rau cov khoom tawg thiab kev sib koom ua ke cuam tshuam.
7. Tsis tu ncua ntsuas qhov tso pa tawm ntawm lub qhov hluav taws xob ntawm qhov hluav taws xob reflow vuam qhov cub, uas cuam tshuam ncaj qha rau vuam kub.
