Kuv tuaj yeem tiv thaiv cov hlau ntawm cov hlau tsis muaj tshuaj lom li cas?
Ua ntej ntawm tag nrho cov, PCB factories yuav tsum siv ROHS tin hlau thaum soldering Cheebtsam nrog hluav taws xob soldering hlau, thiab yuav tsum tau ceev faj:
Piv txwv li, hnav hnab looj tes, lub qhov ncauj qhov ntswg lossis lub qhov ncauj qhov ntswg, ua tib zoo saib xyuas qhov cua hauv qhov chaw ua haujlwm, muaj lub tshuab ua pa zoo, ua tib zoo saib xyuas tom qab ua haujlwm, thiab haus cov mis nyuj kuj tuaj yeem tiv thaiv cov hmoov txhuas hauv cov hlau.
1. So rau ib lub sijhawm, feem ntau yog li 15 feeb txhua teev, kom txo tau qhov qaug zog, vim tias koj qhov kev tawm tsam yog qhov qis tshaj thaum koj nkees.
2. Kev haus luam yeeb tsawg dua thiab haus dej ntau tuaj yeem tshem tawm feem ntau ntawm cov khoom tsis zoo uas nqus tau thaum nruab hnub.
3. Haus cov kua txiv hmab txiv ntoo los yog dej zib ntab ua ntej yuav mus pw. Qhov no tuaj yeem txo cov cua sov sab hauv thiab pab koj lub siab. Tsis tas li ntawd, mung taum thiab zib ntab tuaj yeem tshem tawm ntau cov hmoov lead thiab hluav taws xob.
4. Koj tuaj yeem ua kom cov hlau nplaum ci dua me ntsis thiab sim siv lub taub hau PPD. Nyob rau hauv txoj kev no, thaum kub nce mus txog qhov kub thiab txias, koj tuaj yeem siv cov roj soldering tsawg dua thiab rosin kom txo tau qhov mob rau lub cev.
5. Thaum cov roj solder haus luam yeeb, sim tig koj lub taub hau mus rau sab. Thaum txhuam cov dej, koj yuav tsum tig koj lub taub hau mus rau sab thiab sim tuav koj txhais tes.
6. Siv cawv ntau dua. Yog tias koj txhuam nrog cawv rau ib ntus, cov nyhuv yuav luag zoo ib yam.
7. Ntxuav koj txhais tes tom qab vuam.
8. Ua ntej yuav mus pw. Sim mus pw ntxov thiab sawv ntxov kom pw tsaug zog txaus. Tsuav koj tsaug zog zoo, impurities tuaj yeem raug tshem tawm nrog lub cev.
9. Hnav daim npog qhov ncauj mus ua haujlwm.
