Ua ntej thiab qhov tseem ceeb tshaj plaws, thaum soldering Cheebtsam nrog cov hluav taws xob soldering hlau, PCB cov chaw tsim khoom yuav tsum siv ROHS tin hlau thiab ua tib zoo saib xyuas kev nyab xeeb, xws li hnav hnab looj tes, roj hmab qhov ncauj qhov ntswg, lossis qhov ncauj qhov ntswg. Lawv kuj yuav tsum tau xyuam xim rau qhov cua hauv qhov chaw ua haujlwm thiab qhov zoo ntawm cov pa tawm, nrog rau kev tu tom qab ua haujlwm. Lead lom nyob rau hauv solder yuav zam tau los ntawm haus mis nyuj haus.
1. Siv sij hawm so ib ntus: feem ntau, koj yuav tsum so txhua teev li 15 feeb kom txo tau qhov qaug zog vim tias qaug zog ua rau tsis zoo.
2. Txhawm rau kom ntseeg tau tias feem ntau ntawm cov tshuaj lom neeg nqus tau raug tshem tawm thaum nruab hnub, haus luam yeeb tsawg dua thiab haus dej ntau dua.
3. Ua ntej yuav mus pw, haus ib co kua txiv hmab txiv ntoo los yog dej zib ntab los pab koj so kom txaus thiab ua kom koj lub siab zoo. Mung taum thiab zib ntab kuj tuaj yeem pab koj tshem tawm ntau cov hmoov lead thiab hluav taws xob.
4. Siv koj lub xov tooj ntau dua, PHS tsawg dua, thiab tsawg dua thaum koj tsis tuaj yeem tawm hauv tsev kom txo tau koj cov hluav taws xob tsawg.
5. Txhawm rau kom tsis txhob muaj kev puas tsuaj rau lub cev, koj tuaj yeem ua kom cov hlau nplaum ci dua thiab sim siv PPD lub taub hau vuam. Qhov no yuav cia qhov kub thiab txias kom tsis txhob siv ntau li rosin lossis vuam roj.
6. Sim tig koj lub taub hau mus rau sab thaum cov roj solder pib haus luam yeeb. Koj yuav tsum tig koj lub taub hau mus rau sab thaum koj txhuam cov dej. Sim tsis txhob ua pa.
7. Txhuam nrog cawv rau ib lub sijhawm thiab siv dej Tianna tsawg kom tau txais txiaj ntsig zoo sib xws.
8. Ntxuav tes.
9. Siv da dej kom sai li sai tau ua ntej koj mus pw kom koj sawv ntxov thiab pw tsaug zog txaus. Cov impurities tseem ceeb yuav raug tshem tawm ntawm koj lub cev thaum koj tsaug zog txaus.
10. Tsis txhob npog lub qhov ncauj ntawm qhov chaw ua haujlwm.
