Yuav ua li cas kom nyob deb ntawm kev siv ib tug soldering hlau nrog phom sij solder hlau
Ua ntej tshaj plaws, PCB cov chaw tsim khoom yuav tsum siv ROHS tin hlau thaum soldering Cheebtsam nrog hluav taws xob soldering hlau, thiab ceev faj: xws li hnav hnab looj tes, lub qhov ncauj qhov ntswg los yog roj qhov ncauj qhov ntswg, xyuam xim rau qhov cua hauv qhov chaw ua hauj lwm, ib tug zoo pa system, thiab xyuam xim rau. ntxuav tom qab ua haujlwm. Txoj kev haus cov mis nyuj kuj tseem tuaj yeem tiv thaiv cov kab mob toxicity hauv solder.
1. Siv sijhawm so rau ib lub sijhawm: Feem ntau, koj yuav tsum tau so li 15 feeb hauv ib teev kom txo tau qhov qaug zog, vim qhov kev tawm tsam yog qhov phem 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, uas tuaj yeem txo qhov hluav taws kub thiab pab lub siab, thiab cov taum thiab zib ntab tuaj yeem tshem tawm cov hmoov txhuas thiab hluav taws xob ntau.
4. Kom tsis txhob muaj hluav taws xob, sim zam kom tsis txhob tos lub xov tooj ntawm tes.
5. Koj tuaj yeem ua kom cov hlau soldering ci dua, thiab sim siv PPD lub taub hau soldering, yog li ntawd thaum qhov kub thiab txias, koj tuaj yeem siv cov roj soldering tsawg thiab rosin kom txo qhov kev puas tsuaj rau lub cev.
6. Thaum cov roj solder thiab solder haus luam yeeb, sim tig koj lub taub hau mus rau sab, thiab thaum txhuam saum ntuj thiab dej, koj yuav tsum tig koj lub taub hau mus rau sab, thiab sim ua kom koj ua pa.
7. Siv cov dej cawv tsawg dua thiab ntau dua, thiab txhuam nrog cawv ib ntus yuav muaj txiaj ntsig zoo ib yam.
8. Ntxuav koj ob txhais tes.
9. 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 tawm nrog lub cev.
10. Ua haujlwm nrog lub npog ntsej muag.
