Vim li cas vim li cas soldering hlau tsis lo rau tin
1. Xaiv qhov kub thiab txias uas yog dhau lawm tuaj yeem yooj yim ua rau oxidation hnyav ntawm solding hlau ntxeev ntawm lub tin nto.
2. Tsis txhob noj cov tin ntawm lub tin coated nto ua ntej siv.
3. Siv cov qauv kev ntxuav tsis raug.
4. Cuam tshuam ntawm flux hauv impure solder lossis vuam hlau.
5. Thaum kev ua haujlwm kub tshaj 350 degree thiab surning nres rau ntau tshaj 1 teev, tus nqi ntawm cov soldering soldering cam cov lus qhia yog tsawg heev.
6. Qhuav hlawv "hluav taws xob soldering hlau cov lus qhia, thiab cov hluav taws xob soldering hlau, tuaj yeem ua rau cov hluav taws xob nrawm ntawm cov hluav taws xob soldering hlau taub.
7. Lub flux siv yog cov xeb zoo, ua rau muaj cov oxidation sai ntawm soldering hlau taub.
8. Siv nruab nrab thiab cov tub rog ua yeeb yam flux, tsis tas tu cov pa oxide rau cov taub hlau cam.
9. Tiv tauj nrog cov tshuaj organic xws li plastics, roj nplua nyeem, lossis lwm qhov sib txuas. Ib txwm tuav txoj kev.
Yuav ua li cas rov qab cov hlau xyaum uas tsis lo rau tin
1. Txo qhov kub ntawm soldering chaw nres tsheb mus rau ib puag ncig 280 degrees, muab cov samp daim txhuam cev thiab pheej tiv thaiv cov shap dua tsis muaj kev cuam tshuam. Rov ua cov kauj ruam saum toj no kom txog thaum tsis muaj lead-dawb soldering cam taub yog ci ntsa iab thiab soldered.
2. Tom qab soldering, nrhiav lub tooj hlau tooj los yog soldering nqus xaub thiab solding hlau ntsia hlau kom txog thaum cov hlau tawv tau puv.
3. Kho qhov kub ntawm cov hlau solding rau 300-360}}}}}}}}}} pa tawm hlau los tsoo cov cam taub hau hlau.
